[Server-devel] XS 0.7 CentOS boot hang

2013-08-20 Thread David Leeming
Hi,

 

Apologies if this has been covered before.

 

I noticed that sometimes an XS 0.7 installation will hang in the boot screen
(the advancing white shaded bar bottom of screen). I have not been able to
fix this other than by reinstalling. I read somewhere there is a bug
involving X11 and the fix is to boot in single user mode and delete
xorg.conf. But tried that and it still hung but with scrolling boot text on
the screen.

 You can try disabling the pseudo-graphical progress bar to get more

I usually hit F2 to see when it slows down or hangs (like when it
doesn't get a dhcp lease on the WAN port).

 On a system that hangs, choose to edit the default boot option before the
 countdown timer finishes.  Delete the rhgb (Red Hat Graphical Boot) and
 quiet parameters, and then tell Grub to let the system boot to see if
the
 hang point becomes obvious.

It's not clear to me why you are holding the X key here, are you
expecting that to upgrade the firmware from the rom file?

It doesn't quite work like that. What the X does is make the laptop
boot in secure mode. Your laptop has security disabled (as you
mentioned: no wp tag) but by pressing X you are simulating
security-enabled. As designed, this then goes and looks for an
activation lease or developer key, and fails. (it wouldn't have
upgraded the firmware from the .rom even if you made it happy with the
appropriate lease/key)

Anyway, no manual firmware upgrade should be necessary. Lets figure
out why the reflashing doesn't work.

Hi,

Thanks again. The laptops are good to go for this school year (12.1.0). 
I will be able to work the collection stick problem when I return to the 
schools (probably in December).
I'll double check the flash time to check for variability between units.

At these schools all the laptops are XO-1 or XO1.5. However, I think a 
Nandblast facility working across all the models would be very useful 
for the start-of-year update.

Yours,

Tony

 Hi,

 Thanks again for this!

 What I gather is that we should use Nandblast from an XO for
 reflash. For a time it was not supported for XO-1.5, but my current
 understanding is that it supported for all versions of XO.
 Up to 13.1.0 it is supported on XO-1, XO-1.5 and XO-1.75.

 It is fast for XO-1, and quite slow for XO-1.5 and XO-1.75.  The
 breakeven point, where I would switch from USB drive to NANDblaster,
 is about five XO-1, and about twenty for XO-1.5 and XO-1.75.

 In 13.2.0 it is broken, and I am working on that in ticket #12726,
 hoping to get fixes in before release.  Fixes are available for XO-1
 (Q2F19) and XO-1.5 (Q3C16).  XO-1.75 is still a problem.

 It was not intended to be supported on XO-4 with the new 802.11n
 wireless card, but so far it looks possible.

 In Lesotho, the flash was taking 15min from boot to reboot for
 registration. These laptops (XO-1) date from the first G1G1 and so
 there is no telling about endurance.
 That time of 15 minutes is far too long, and should be investigated
 ... if the internal storage is three times slower than when the
 laptops were produced, you will have performance problems.  I have
 some old XO-1 units here that have been used by children, and they are
 not showing that symptom.

 Naturally, reload of the Journal occurs via the file system after
 the flash. Sadly, this is not a current issue because none of the
 deployments actually use the Journal (e.g. in Lesotho the laptops
 are shared among several students).

 The laptops (XO-1.5s) at Saint Jacobs were sponsored by a group in
 Stuttgart and are not part of the Rwanda purchase. In any case, I
 believe the information needed for the collection stick is available
 (serial number and uuid).
 If it is already available, get it to me.

 Yours,

 Tony

 The 'locked' XO problem derives from XOs distributed in the minimum
 100 XO purchase - many of these are locked. Also, in Rwanda the
 policy is to keep the laptops locked even though they have
 indefinite leases.
 Rwanda probably has a deployment key and should be able to sign builds
 with it.  My guess is that the laptops would also have the deployment
 keys injected already.  You will need to work with the people who have
 the keys.

 My current plans are to visit these schools in December and so I may
 be able to get them unlocked then.
 http://wiki.laptop.org/go/Collection_stick is perfect for this,
 provided the deployment did not remove the OLPC keys.

 (I don't have records of what deployments have done).

 What I would really love is a 'Nandblast' capability in the firmware
 that gets it's image from the schoolserver. That probably would work
 (how does an XO know an image is coming over wifi from an XO or a
 school server?).
 There is no implementation of NANDblaster for the school server,
 because it requires special support in the wireless device.  A typical
 access point will not work.  It requires an XO as the sender.

 (NANDblaster is implemented in the firmware, not the operating system.
 An alternate design could be engineered, but that doesn't seem likely
 to be attempted.)

 The normal flash problem is that several XOs need to be reflashed at
 one time, so the usb key approach is time-consuming. My experience
 is that a reflash from usb key takes 15min. Naturally, one key to
 this process is the ability to reload the backed up (hopefully)
 Journal.
 Reloading the backed up journal is costing you 10min?  Reflashing an
 XO-1 from USB drive 13.2.0-12 costs only 5min.  If the reflash is
 taking much longer than that, there may be an endurance or end of life
 problem with the internal storage of the XO.

[Server-devel] Installing XSCE on XO-1

2013-07-01 Thread David Leeming
Hello,

 

Can anyone confirm that XSCE 0.3 has been successfully installed on an XO-1?


 

If so, the starting point would be installing 31036o0.img (not .zd) onto an
external 8GB+ SD card?

 

We want to try this here in rural PNG but need to be sure as it is a long
job with the downloading 

 

Oh yes, we tried to prepare an XO-1 as per the instructions on the wiki
(installing the os on an SD card) but failed at the first step - we can't
get a developer key for the XO because activation.laptop.org uses an
invalid security certificate (Error code
sec_error_expired_issuer_certificate). How can we get the developer key? We
don't have any unlocked XOs available... (we checked the date/time on the XO
was correct)

Re: [Server-devel] Best XSCE strategy for us in Pacific with XO-1.5 2GB Testing XSCE 3 on XO 1.5 2GB os855

2013-06-20 Thread David Leeming
Successfully installed XSCE 0.3 on my XO-1.5 (2GB) after first installing XO
release 13.1.0 on an 8GB external SD card and then following the standard
procedure. First time I ran xs-setup there were some errors probably caused
by connectivity issues but when I re-ran xs-setup it successfully completed.
Moodle is there, all looks good. I will put a selection of our Pacific
Islands content and test our normal Moodle configuration (very basic) and
try it out with some teachers in a scheduled training in a couple of weeks
time. 

Also will try and get a 32Gb or 64Gb card and install on that. I noted
Anna's advice and copied the yum cache. When I repeat with the larger card I
will try and use that to reduce downloading.

All going well so far - managed to install the 13.1.0 os on an 8GB SD card
and have proceeded with the XCSE installation up to including the bootstrap.


I assume that as it is on the external SD card anyway, I don't need to run
prep-storage?

I was also wondering, how important it is to have a USB Ethernet adapter
present whilst setting it up and whether it needs to be active (i.e.
connected to an AP) whilst running xs-setup

Finally, is there any performance penalty for running it from the external
SD card?

I looks like the 1.5 lite does not have enough space for the 13.1.0 image.

You will need almost an 8gb hard disk in order to proceed with the
installation. If the internal hard disk is less than that, you can use
a sdcard to install the system, check the following
instructions:http://activitycentral.com/community/news/installing-os-sd-card

Re: [Server-devel] ANNOUNCEMENT XSCE 0.3 Final Release

2013-06-11 Thread David Leeming
This is very exciting. I am just starting on a 200 XO 1.5 deployment in
Solomon Islands and will give this a whirl.

 

We have XO 1.5s with only 2GB onboard. Is that enough?

 

I have seen the wiki pages and will work on that but if there are any tips,
I will be watching this list, of course I will give my feedback too.

 

I particularly want to use the 30GB of content that the Pacific islands
jointly collected together (mostly OERs). The way we did this on the XS 0.7
was to put the content folders in /library and set up aliases in html.conf
and then add links to resource or website on the Moodle pages. Can I
assume I can do the same with XSCE 0.3 using a 32GB or 64GB SDRAM card?

 

To install, is it possible to down the image and install with a flash drive?
Then I can get the download from one of the few places here where we can get
a decent download speed, and install more than one at my leisure.

After three months of hard work and three weeks of working out the kinks
in the release process, XSCE 0.3 is ready for its final release. 

 

We went conservative this release. Emphasis on stability meant less time for
new features.

 

* XSCE now runs on the XO-1.5,XO-1.75 and  XO-4.

* Modular Architecture: cleanly integrate extendable services.

* XSCE runs on the XOs' current OS 13.1.0 (we discovered some wrinkles with
13.2.0 which push its use off to the next release)

* Moodle is Back!

* Content filtering via openDNS.com

* Script for formatting of SD cards, and integration into system for content
storage and memory extending swap file (does not work on XO4's)

 

 

Grab an XO-1.5, XO-1.75 or a XO-4 to give XSCE 0.3 give a whirl:

 

 http://schoolserver.org/0.3 http://schoolserver.org/0.3

 

If you are just getting started with XSCE we suggest using the instruction
at
http://wiki.laptop.org/go/User:Holt/XS_Community_Edition/0.3/Installing
http://wiki.laptop.org/go/User:Holt/XS_Community_Edition/0.3/Installing to
install your first server.

 

Once you are through the install, a good second step is to work your new
server though it's paces by doing the smoke test at

product real.

Re: [Server-devel] 12 Volt power system for School Servers.

2013-05-30 Thread David Leeming
We have a primary school in PNG with school server driving 9 wireless access
points with PoE to cover a 200 laptop deployment with 7 classrooms 

http://wikieducator.org/OLPC_PNGSDP/Kisap 

Powered by 12V solar using the excellent Sundaya kits. The wiring looks
untidy, I know, but they have worked very reliably over 2-3 years. Also the
integrated batteries and proprietary DC connectors make it difficult to
misuse the power (a common cause of early demise of batteries)

http://www.sundaya.com/welcomeEN.php 

The Mikrotik GrooveA range of outdoor wireless access points are really
good. They will work on 9-27V so even with 12V, you can get very long cable
runs, and you can screw in a vertical omni or your antenna of choice. We
didn't use them in the deployment above but I would do in the future.

Tony makes an interesting point that may be new to some:

On Thu, May 30, 2013 at 06:47:26AM +0200, Tony Anderson wrote:
 This discussion is relevant because 12vdc does not travel well over
 long distances. It may be necessary in a school with multiple
 classrooms to use an inverter to provide 110 or 220vac to the
 routers via PoE.

As the distance between the battery bank and the access point
increases, so too does the required _diameter_ of copper cable.

Copper cable is quite valuable, and easily traded.  It can be a good
security practice to avoid installing too much of it.

If the cable is too thin, the power demand by an access point causes
too much of a voltage drop.  For instance, one might put 12V DC in one
end, and get 10V DC out the other end.  The access point may still
work fine.  But some of the power will be lost as heat in the cable,
lowering efficiency.

At some point, depending on cost, reliability, and availability of
equipment, it is worth operating at a higher voltage.

The options would seem to be Power over Ethernet (PoE), which will
yield 12.95W (IEEE 802.3af-2003) or 25.5W (IEEE 802.3at-2009), or an
inverter with a separate power circuit.

My best guess is that PoE will be cheaper, because a power circuit
installed to meet electrical regulations would tend to be designed for
the minimum domestic power standard of the country.  For example, in
Australia the minimum is 10A at 240V, or 2400W.  The mass of copper
is far more than what PoE would require.

Then there's the cost of a 12V input PoE power sourcing equipment
(PSE).

Hello,

 

We're conducting an assessment of server activity reports in a few schools

Is there a way to copy the activity report source data (logs??) on to

 Just to check one of the basic details...
 Are you aware that the XS-0.7 doesnt configure network by default? You
 must take extra steps.

2012-08-01 Thread David Leeming
Thanks Peter,

dmesg | grep eth

shows that the kernel sees the hardware, at least eth0 and eth1 hardware/MAC
addresses are shown, and those agree with that shown from ifconfig -a which
shows eth0, eth1 and lo but only lo with inet address (loopbackl). The
physical ports appear to be inactive, the LEDs don't light up and when
trying with a cable and computer, no network detected.

Reinstalling with 0.6, the networking works fine

mii-tool is mostly (should be completely) obsolete. You should use
ethtool for this functionality as it will work with all detected NICs.
dmesg | grep eth will let you know what the kernel sees.

The Marvell ethernet ports might not be well supported on CentOS 6.
You might want to check if a newer CentOS kernel adds support.
Alternatively you can likely use a Fedora kernel. dsd did that when he
had issues with NIC support on one of the deployments he was involved
with. I suggest checking the mailing list archives for the details.

[Server-devel] XO names when sharing with server

2012-05-11 Thread David Leeming
I am sure this has been covered before, but would appreciate a reference to
the thread...

 

I am using XO-1s, release 11.3.0 (build 883) with Sugar 0.94.1 and we are
still using XS version 0.6 with the latest updates.

 

When using XOs connected and registered on the server to collaborate, the
names of XOs which populate the neighbourhood view are displayed as very
long strings ending something like @schoolserver.fqdn.org rather the correct
friendly name. This also affects how activities perform when
collaborating. Connect for instance, becomes difficult to use because the
long name of the joined XO causes the playing area to resize to a small area
on the right of screen.

 

It doesn't seem to do this when using the mesh.

 

Not sure if this is a server, the OS build or Sugar issue. It used to be
fine with earlier XO builds and the same server version.

 

Apologies if this has been covered before - if there is a ticket I can view
or whatnot, would appreciate the tip.

The Apache error logs suggest that the database connection failure is

I am copying you separately a document that we use in PNG and Solomons that
helps with a basic default installation of XS 0.6 and some very basic Moodle
settings. It's a bit country/project specific so I need to clean it up
before sharing on this list. I have installed from a USB stick before, but
it's a while ago. OLPC-AU do this so will leave that to Sridhar. We use CD

Hi David,

Sorry for my delayed reply.  Thanks for your comments and advice.  Please
do send me the specs for the EPC-AT270 you are using.

I tried downloading the XS operating system from the OLPC website onto a
dongle/flash drive and installing it from that onto the PC we have
designated as our server, but the installation failed.  Later, we had two
computer specialists reformat the PC and try the same thing without
success.  Each time, we got errors that said the XS files were incomplete.

Did you install your XS software from a dongle, or did you download it
directly onto your server?
If you installed from a dongle, do you have any suggestions on what we
might be doing wrong?
Do you know if there is information anywhere with very detailed,
step-by-step instructions for installing the XS from a dongle?

We are all total Linux and XS novices, and none of us have ever operated a
server before.  Since we haven't been able to install the XS, I'm
unfamiliar with the XS features you mentioned (Moodle home page, /library,
class segregation etc.)

Hi Janissa

Your programme sounds very worthwhile and I wish you all the best with it!

Maybe I was not clear, but my point is that for us, the XS (we are using
v0.6) installed on a low power e-box such as the EPC-AT270 (I can send you
the spec sheet, it is available in Australia not sure where you are) has
proven exactly what you seem to be looking for. Very low power, running at
15W or less on 12V DC solar power, with auto-power on enabled so even if
there is a power outage the locals don't need to intervene. At one site it
ran 18 months continuously and no problems. The access points all using
DC power via PoE too.

Our schools in PNG only theoretically have Internet access in some
locationsas the quality of service is insufficient. Even if it were, it's
only for the teachers due to cost. But the teachers do have some limited
options with 3G dongles if they wish to sign up to the OLPC-Australia
XO-Certification programme (extended to Pacific) laptop.moodle.com.au and
so we spent time training them to do so.

It is true one does need some initial centralised or outside expertise
to set the servers up but in our case we are all Linux novices really and we
get by. On site, as I said the servers are very useful, but as in your
case we have to just install and leave them and expect little maintenance
work although as time goes on various champions emerge. I am typing this
in the remotest place in PNG, and yet I am planning today to training one
teacher to be able to do some role assignment work on the XS Moodle in
some
schools we can't visit this time.

I guess this list can help you design a suitable configuration for the XS.
As I said in our case it is really basic, just using the Moodle home page
as a links page to folders of resources in the /library, and some upload
folders and the general news/forum. We don't use the class segregation as
yet because we are unable to assist when the students change class at the
new year, so the strategy is just to tell teachers try not to overload the
server, coordinate with each other etc. In the future we can improve on
it.

[Server-devel] Collaboration XO-1 with XS

2012-04-26 Thread David Leeming
I have noticed when using the combination XO-1 build 883 , Sugar 0.94.1 and
XS-0.6 that collaboration for registered XOs connected to the XS network is
unreliable. After doing some collaborating sometimes the populating of the
neighbourhood views becomes unreliable and shared activities are not
displayed on other XOs neighbourhood screens. Also, when hovering over some
XOs which are displayed on neighbourhood view, the name is not shown but
instead a long text stream. This has been attempting to disrupt teacher
training I am conducting but we work around it by for instance using
discard network history which seems to help.

 

I am copying to both lists as I am not sure where the problem lies. Any
advice appreciated and apologies if some of this has been covered in past
discussions, if so just a referral would be most appreciated.

 Normally named.run should only contain a number, a small integer.

 If you restart the server, after having removed named.run, and let it
 run for a while, what happens with named.run ?

This is a server machine I carry about to use in field trainings. Typically
I use a Windows laptop connected to the server network with a VNC client
running, to use with a projector to display XOs (using Classroom Broadcast).
I have not had any problems before, perhaps I did not reach the limit. It is
now clear this is due to the Windows laptop antivirus trying to update:
after deleting named.run, a few hours later it is getting up to 100MB and it
turns out that is made up of lines as below the below: 

network unreachable resolving 'dnl=12.geo.kaspersky.com/A/IN' ;

I also have problems this trip with collaboration. We only have 25 teacher's
XO-1s (b883, sugar 0.94.1) and all are registered and appear in the Moodle
user list. But the neighbourhood does not reliably populate and when sharing
an activity the sharing icon does not reliably appear on all the other XOs
neighbourhood view making it difficult to do collaboration training. Is
there an issue with the combination of XS v0.6 and the particular XO
build/sugar version? Or maybe something on my server is broken,

[Server-devel] Browse or Moodle-XS error - Redirect Loop Redirection limit reached

2012-04-23 Thread David Leeming
Hello, 

 

I am running a training session on the school server but not sure if my
problem is Browse or XS so copying to both lists. 

 

The trainees are teachers, learning the basics - they have zero computing
experience. We are using Browse 129.1 and XS 0.6 with current updates. They
have learned to connect to the wireless network and register. The group size
is 25 and there are more than one (4 actually) physical access points.

 

Moodle-XS is used to present links to folders of resources via URL aliases.
Example, a link such as

 

http://schoolserver/MyResource pointing at folder /library/myresource

 

thus, the resources don't actually need Moodle to work.

 

Suddenly all the trainees when trying to access the server Moodle pages with
Browse get the error: 

 

Redirect Loop : Redirection limit for this URL exceeded.

 

I can type in the URL alias http://schoolserver/MyResource manually and it
will display the content OK. 

 

So it seems to be a Moodle issue? How to deal with it? I have never seen
this before ...

Regarding the below, it seems that the database is not running and on
checking disk space, the file system /dev/sda2 is 100% used. I am assuming
this is the cause of the problem. We don't use that area for storage, all
our resources are saved in /library. So I guess that it might be the
database or other dynamic resource that has increased in size to the maximum
available on this server. 

Looking for advice on what to do to free up space and get it working again,

Re: [Server-devel] Browse or Moodle-XS error - Redirect Loop Redirection limit reached

2012-04-23 Thread David Leeming
 

Regarding the below, it seems that the database is not running and on
checking disk space, the file system /dev/sda2 is 100% used. I am assuming
this is the cause of the problem. We don't use that area for storage, all
our resources are saved in /library. So I guess that it might be the
database or other dynamic resource that has increased in size to the
maximum available on this server. 

Looking for advice on what to do to free up space and get it working again,

 

Should have waited before posting; I found in filesystem /dev/sda2 several
large message log files, on erasing them all works sweetly 

 

Also found a file named.run which is nearly 1GB in size, - I gather this is
a debugging file, can I disable the function that generates it? Will
named.run continue to grow with our deployed servers, all of which use the
default install (version 0.6)?

Subject: [Server-devel] Browse or Moodle-XS error - Redirect Loop
Redirection limit reached

 

Hello, 

 

I am running a training session on the school server but not sure if my
problem is Browse or XS so copying to both lists. 

 

The trainees are teachers, learning the basics - they have zero computing
experience. We are using Browse 129.1 and XS 0.6 with current updates. They
have learned to connect to the wireless network and register. The group size
is 25 and there are more than one (4 actually) physical access points.

 

Moodle-XS is used to present links to folders of resources via URL aliases.
Example, a link such as

 

http://schoolserver/MyResource pointing at folder /library/myresource

 

thus, the resources don't actually need Moodle to work.

 

Suddenly all the trainees when trying to access the server Moodle pages with
Browse get the error: 

 

Redirect Loop : Redirection limit for this URL exceeded.

 

I can type in the URL alias http://schoolserver/MyResource manually and it
will display the content OK. 

 

So it seems to be a Moodle issue? How to deal with it? I have never seen
this before ...

Hi Janissa

Your programme sounds very worthwhile and I wish you all the best with it!

Maybe I was not clear, but my point is that for us, the XS (we are using
v0.6) installed on a low power e-box such as the EPC-AT270 (I can send you
the spec sheet, it is available in Australia not sure where you are) has
proven exactly what you seem to be looking for. Very low power, running at
15W or less on 12V DC solar power, with auto-power on enabled so even if
there is a power outage the locals don't need to intervene. At one site it
ran 187 months continuously and no problems. The access points all using DC
power via PoE too.

Our schools in PNG only theoretically have Internet access in some locations
as the quality of service is insufficient. Even if it were, it's only for
the teachers due to cost. But the teachers do have some limited options with
3G dongles if they wish to sign up to the OLPC-Australia XO-Certification
programme (extended to Pacific) laptop.moodle.com.au and so we spent time
training them to do so.

It is true one does need some initial centralised or outside expertise to
set the servers up but in our case we are all Linux novices really and we
get by. On site, as I said the servers are very useful, but as in your case
we have to just install and leave them and expect little maintenance work
although as time goes on various champions emerge. I am typing this in the
remotest place in PNG, and yet I am planning today to training one teacher
to be able to do some role assignment work on the XS Moodle in some schools
we can't visit this time. 

I guess this list can help you design a suitable configuration for the XS.
As I said in our case it is really basic, just using the Moodle home page as
a links page to folders of resources in the /library, and some upload
folders and the general news/forum. We don't use the class segregation as
yet because we are unable to assist when the students change class at the
new year, so the strategy is just to tell teachers try not to overload the
server, coordinate with each other etc. In the future we can improve on it.

Subject: [Server-devel] Lesotho project network server: obstacles  needs

I work with a non-OLPC-affiliated XO laptop project in Lesotho.  Our
project uses G1G1 XO-1 laptops we buy on the open market and refurbish
ourselves.

Like David Leeming in PNG (see Server-devel Digest, Vol 60, Issue 13,
Topic 1 -- Re:  Looking for new low power server hardware candidate), I
work with schools in a very remote area with rough terrain, difficult
access, limited resources, and poorly trained teachers.  Unlike David's
area, our schools do not have access to internet.

The teachers we work with have absolutely no computer experience coming
into our program.  They are all eager to receive training and use the
computers in their classrooms, but because of their own poor education,
they have trouble following general instructions and retaining the
computer skills we teach them.  We find that they need very detailed,
written, step-by-step instructions for everything.  Most of the time, they
are incapable of extrapolating what they've learned and applying it to a
slightly different situation or another activity.

Much of the teaching at the schools is done in English, despite the fact
that English is the teachers' second language.  Many of them have small
vocabularies with low language proficiency.

Those of us helping them are educators and administrators, not computer
technicians.  For us, most of the discussions and instructions in this
server-devel forum go way over our heads.  We have tried to get computer
specialists to help us set up a server, but this is nearly impossible
because it requires a commitment of days to reach and service our area. 
Twice, computer volunteers have come to our first school to install the
server software from a CD onto a standard PC. But, both times the OLPC XS
software didn't work and/or was incomplete.  Without internet access, they
were unable to complete the process.  After two years, we still do not
have a functional server for the 86 laptops at that school.  We haven't
even tried to set up a server at our other school, which will have a total
50 XO laptops by the end of this year.

Our schools charge and operate all their computer equipment off solar
panels

[Server-devel] Changing domain name

If I change the domain name of an XS (version 0.6 + updates, default

Re: [Server-devel] deregister laptops

2011-05-15 Thread David Leeming
HI, what I am trying to do is restore an XO-1 running build
860/0.84.31/Q2E45 that has been registered on one XS to a condition where it
can be registered on another XS. When you register, the register option
disappears from the options on the home page when you point at the icon in
the middle. We want that back again so it can be used with another XS. On
previous versions you would use Terminal and
/rm/home/olpc/.sugar/default/config

I tried sugar-control-panel -c registration and get this error:

sugar-control-panel: Failed to contact configuration server; some possible
causes are that you need to enable TCP/IP networking for ORBit, or you have
stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/
for information. (Details -  1: Failed to get connection to session: Did not
receive a reply. Possible causes include: the remote application did not
send a reply, the message bus security policy blocked the reply, the reply
timeout expired, or the network connection was broken.)

I must be missing something obvious? Of course we can always reinstall but
would prefer more elegant solution ...

Re: [Server-devel] XS-0.7 plans -- your thoughts please...

2011-01-18 Thread David Leeming
Great news, looking forwards to 0.7

I think three areas where we had some difficulties.

1. Perhaps making the default install easier to set eth0 up for static
config
2. Not sure if it is relevant to the build, but we would have enjoyed an
easy way to clone from a master, i.e. when setting up a customised XS for a
number of schools 
3. We had difficulties running the olpcxs update (yum --enablerepo .) at
times, and although we couldn't always replicate the problem it seemed to be
related to clock/date/time skew 

I have never tried selecting the Gnome option, but a nice GUI would be
useful for users with limited grasp of command line stuff for file
management. Maybe that is available already

Managing a system with Gnome sounds seductive, but I can't think of a faster
way to bork up a server than to let a novice admin loose in GUI tools with
root powers.

For file management, say a user level directory under /var/www/html, far
better to mount it with sshfs from a remote system (there's even a Windows
tool for that called dokan).  That way you can have the ease of a GUI
filesystem tool without the risks of actually running a Window Manager on
the server itself. Not to mention installing Gnome and X Windows and all the
deps takes a ton of space.

 Even if a location doesn't have internet access, daily reporting of the

At

trying to achieve is to get the Register to appear on the XO home page
when you hover over the middle, under Shutdown and My settings; i.e. to
have the Register option available again in the shutdown dropdown menu so
that I can register the XO on another XS.

We have to do this quite often, for instance right now we have 25 teachers
from 3 schools with OLPC projects visiting one school for training. They all
need to access the XS server at that school, using their own laptops.

Hence we need to deregister them. I am not sure if this question is for the
Sugar dev or server dev list, but is certainly server related.

Any help appreciated! We are stuck at the moment. We are otherwise stuck; we
upgrade them XOs to 10.1.2 and now don't have access to the server without a
lot of time consuming work.

(it is a pity as the rm /home/olpc/.sugar/default/config method was well
understood here)






There's an alternate method using the gconftool-2 program that is
somewhat more complex.





gconftool-2 --set --type=string \
/desktop/sugar/backup_url \
''

And finally a brute force method rm -rf .gconf but this destroys other
settings, most of which may not be important.

Yes. And if the NICs are replaced too.

It's not enough however (from a correctness PoV) when cloning a disk.
There's a number of files that get generated on first boot -- the ssh

Unfortunately there isn't an easy command on linux distros to return

[Server-devel] Cloning and hardware addresses

2010-12-02 Thread David Leeming
I have been cloning a master XS hard drive onto a number of copies, to be
used in different computers (of the exact same type). I used the following
simple way of cloning

 

dd bs=8192 if=/dev/sda of=/dev/sdb 

 

where sda is the master and sdb is connected via USB. This done using a live
CD to boot it up.

 

The clones work fine in the same PC as was used with the master. However, on
booting a cloned HDD in another machine it does not detect the NICs (the
computer has 2). I assume I have to delete the HWADDR= line somewhere, for
both eth0 and eth1.

 

Question is, where? Or should this be done another way?

 following simple way of cloning
 
  
 
 dd bs=8192 if=/dev/sda of=/dev/sdb 
 
  
 
 where sda is the master and sdb is connected via USB. This done using
 a live CD to boot it up.
 
  
 
 The clones work fine in the same PC as was used with the master.
 However, on booting a cloned HDD in another machine it does not detect
 the NICs (the computer has 2). I assume I have to delete the “HWADDR=”
 line somewhere, for both eth0 and eth1.
 
  

 /etc/udev/rules.d/70-persistent-net.rules
 Delete the lines that refer to all the eth devices and reboot
 Jerry

Sub note to this. I found I had to delete the file altogether. Then it works. 
It regenerates the file with the new hardware addresses so if the HDD is moved 
again, I guess this step needs repeating.

Re: [Server-devel] Bridging XS to another network

2010-11-02 Thread David Leeming
OK thanks Jerry. I have decided to test this out on a safe replicated 
environment rather than risk breaking something, as I'd then not be able to fix 
it in the short time left on site. You gave me the second option, for the few 
fixed Windows PCs that will be involved in the initial part of this project, on 
those I will edit the hosts file. I will be back here next month and will have 
then bring a second machine with me to br about with at no risk!

Many thanks, you've really been a tremendous help, also Anna and other, cheers

   Jerry,
   
   The computers wishing to access the server are Windows laptops that get 
   their DNS from the ISP (actually the gateway router

  This gateway router is handing out the dhcp addresses and the nameserver
  is pointing to google's dns servers? That would be the place to hijack
  the dns for schoolserver, do you have access to this router? Is this
  the second linksys that you refer to below? 
  
  On one of these Windows boxes can you add an entries to
  winpath\system32\drivers\etc\hosts file:
  
  192.168.0.210 schoolserver
  192.168.0.210 schoolserver.patukae.org
  
  and then test with ping:
  
  ping schoolserver
  ping schoolserver.patukae.org
  
  If that is successful, you should be able to see moodle in the browser.
  
  
   The 192.168.0.0/24 network is actually a schoolnet linking several 
   village schools with Wi-Fi bridges 
   and access points, and it has Internet gateway (VSAT). We want all those 
   schools to access the XS moodle and my added wiki.
   
   QUESTION: Yes, I can access the gateway router (it is also a Linksys 
   WRT54G2). Would you know how to add the enter pointing 
   schoolserver.patukae.org to 192.168.0.210, where (in the router admin) 
   would I add that entry? It is not obvious to me, sorry...
   
  
  Give me a bit on that one, I have to check. 
  
 
 Just so were looking at the same thing, Figure 6-13 on:
 http://www.scribd.com/doc/21144997/Linksys-WRT54G-router-manual
 
 I don't see a way of adding any entries, just boxes in the dhcp part for
 the upstream static dns servers, this info is being passed to the
 clients, at a windows cmd prompt, what does ipconfig /all show?
 
 What you need is a nameserver on 192.168.0.XXX to handle the name
 resolution. Think I can rig that up with just the XS, give me a bit.
 
 Jerry

  
The first order of business would be to have named use the forwarders
that are configured in the linksys, because the XS can't resolve
anything outside of its own domain. You can ping google's ip address but
google.com will fail. You need use these directions to add them, you can
skip the service named restart part:

http://wiki.laptop.org/index.php?title=XS_Techniques_and_Configurationsection=15#Use_ISP-provided_DNS_servers

Next edit /var/named-xs/school.external.zone.db changing 18.85.46.29 to
be, in your case, 192.168.0.210

Now restart named:

service named restart

You should now be able to ping from the XS(and the client XOs as well if
you have iptables enabled) to anywhere on the web. 

Don't go any farther unless this works.

Ensure that the linksys that is between the XS and the main router is
acting as a DMZ host for the schoolserver or ensure that both port 80
tcp and port 53 tcp/udp are forwarded to the XS.

Boot your Ubuntu Live CD and edit the /etc/resolv.conf file, change the
nameserver to be 192.168.0.210

now the ping test:

ping schoolserver.patukae.org 
ping schoolserver

Try out moodle.

Don't go any farther unless this works.

On the main router, in the dhcp config page move the other ip addresses
down to the 2  3 slots and fill in the first slot to be 192.168.0.210
and save the changes. The clients will pick up the changes as their dhcp
leases expire, or you can do ipconfig /release, ipconfig /renew to force
the change quicker. We're now handing out the linksys' ip address as the
first nameserver to be used, where it will be forwarded to the XS to
handle. This should result is less traffic up the isp's pipe as the XS
will cache dns requests made to it. The second  third entries on this
linksys would be just backup for if the first nameserver(the XS)failed
to resolve.

2010-11-01 Thread David Leeming
Hi Jerry

That sorted it out - almost...

I added the gateway and the server can now ping through the router.

I added port forwarding for HTTP and success  partially

From the outside I can enter the router WAN IP (which is now 192.168.0.210) and 
mixed results...

http://192.168.0.210 gives the Firefox error Server not found, Firefox can't 
find the server at schoolserver.patukae.org (showing that it has found 
something at least). Same with http://192.168.0.210/moodle/ 

However, the MediaWiki installed on the XS is fine (http://192.168.0.210/wiki 
is fully accessible).

The difference is that moodle lives in /var/www/moodle but the wiki lives in 
/var/www/html/wiki

Would be sincerely grateful for the last piece in the puzzle  so would all 
the teachers here, as this firefighting is going on in parallel with the 
XS/wiki deployment!

 Hi thanks jerry,
 
 Almost there, just need clarification...
 
 On the router, what should I use for the LAN network, like this or different?
 172.18.0.88
 255.255.255.0 
 (is that correct? It means the network does not include the higher ranges 
 172.18.96.xxx etc)
 
That should work, then only the XS has a direct route, while the XOs on
172.18.96.xxx don't.  

 Should the router firewall settings be virtual server port 80 to 
 172.18.0.1??? or 172.18.???.??? 
 What is the main IP address of the XS, I thought is was 172.18.0.1
 

use 172.18.0.1 as the target of the port forwarding, that should work
once the default route is set as below.

 To add a route on the XS, do you mean (and what are the ??/):
 
 route add default gw 172.18.0.88 netmask 255.255.???.??? landbond0??? 
 

Yea that is the idea, but you would need to re-add that upon reboots.
Lets try to get this to auto configure, edit ifcfg-lanbond0:2 from:

if [ $XS_SERVER_NUM = 1 ] ;then
ONBOOT=yes
IPADDR=$XS_LANBOND_MAINXS_IPADDR
NETMASK=255.255.255.0

BOOTPROTO=static
#BONDING_OPTS=
IPV6INIT=no
else
 
To be:

if [ $XS_SERVER_NUM = 1 ] ;then
ONBOOT=yes
IPADDR=$XS_LANBOND_MAINXS_IPADDR
NETMASK=255.255.255.0
GATEWAY=172.18.0.88 
BOOTPROTO=static
#BONDING_OPTS=
IPV6INIT=no
else

That should create the default route via 172.18.0.88, when the network comes up.

restart the network service and retest

service network restart
ping 172.18.0.88
ping 192.168.1.88 

This that fails, can you capture the output of:

Jerry,

The computers wishing to access the server are Windows laptops that get their 
DNS from the ISP (actually the gateway router points to Google DNS).The 
192.168.0.0/24 network is actually a schoolnet linking several village schools 
with Wi-Fi bridges and access points, and it has Internet gateway (VSAT). We 
want all those schools to access the XS moodle and my added wiki.

QUESTION: Yes, I can access the gateway router (it is also a Linksys WRT54G2). 
Would you know how to add the enter pointing schoolserver.patukae.org to 
192.168.0.210, where (in the router admin) would I add that entry? It is not 
obvious to me, sorry...

Other feedback: 

Everything on the XS is default apart from the added wiki. I ran domain_config 
patukae.org, yes. I have not done anything deviating from default installation 
that would cause the @@BASEDNSNAME@@ to appear. 

At the moment from the external net I can browse to
http://192.168.0.210/wiki and it works fine
but not
http://192.168.0.210/ or http://192.168.0.210/moodle 

Maybe the above is relevant?

I'm going to say either your isp's servers, or the ADSL modem is caching

No, not likely.

 The server functions normally when XOs and PCs connect wirelessly or wired to

Anna,

 

What you describe below is what I am trying to do (see the net diagram in my
other email). I only want apache/Moodle/wiki to be available to the external
network (your regular LAN). You'll see that I have a simple WRT54G router
bridging but no matter what I try, I can't see the apache service through
the router. Can you say what Wan and LAN settings you used for your router? 

I used

WAN - fixed 192.168.1.88 / 255.255.255.0

LAN - fixed 172.18.0.88 / 255.255.255.0

Port 80 forwarded from WAN to 172.18.0.1 (or DMZ host with 171.18.0.1)

In this set up: 

If I try to ping from the XS to 172.18.0.88 it is OK, if I try to
192.168.0.88 it says network unreachable.

But if I use a PC hooked up on the eth1 network, with fixed IP 172.18.0.89 /
255.255.255.0 (for example) I can ping the WAN address and beyond. This is
what leads me to think it needs one extra step with route, or it may be
something to do with the WRT LAN setting and XS having different netmasks.
You can see I am reaching at straws a little L  

 

 

 

 

By way of example, here's a setup I've done in the past:

Regular LAN:
XS (eth0) 192.168.1.20
My Desktop 192.168.1.6
XO A 192.168.1.7

XS LAN:
XS (eth1) 172.18.0.1
XO B 172.18.96.2

On the XS LAN, XO B can go to http://schoolserver or 172.18.0.1 and see
the default Moodle homepage.  It can also register to the XS and all that
good stuff, cause it's getting its IP address from the XS's DHCP server.

On theRegular LAN, my desktop and XO A can't see the Moodle homepage at
192.168.1.20 until I open port 80 in the firewall on the XS using lokkit (or
edit iptables or whatever).  Since XO A is not getting its IP address from
the XS, it won't be able to register.  If XO A wants to use the XS's
Jabber server, that port needs to be opened in the XS firewall.  XO A can
now manually set the Jabber server to 192.168.1.20 and collaborate.  If you
want to use Moodle, not being able to register to the XS is a huge issue.
Apache access works fine, though.

Re: [Server-devel] Bridging XS to another network

2010-10-30 Thread David Leeming
Martyn,

 

In regard to the below, I am trying to set up the XS behind a Linksys
WRT54G2 router. 

 

I think my issue is because eth1 (lanbond0) is set up as network
172.18.96.1/255.255.224.0 (for the XOs) but the server listens on 172.18.0.1
(or

 

I have tried to use the route command to add the router LAN IP as the
default gateway but it doesn't work or I did it wrong

 

Could you please tell me what I should use for the LAN settings on the
router? 

 

The WRT54 settings I am using here at home are

.. WAN - static IP, 192.168.1.88 / 255.255.255.0 (external network is
192.168.1.0/24)

.. LAN - static IP, 172.18.0.88 / 255.255.255.0 (could it be the
netmask? The WRT only allows up that setting , i.e. 255.255.224.0 is not
possible)

.. Port forwarding, I tried everything, including UPnP forwarding and
DMZ Host with 172.18.0.1 as the IP

 

At the moment I can't ping from the XS to the Linksys WAN IP (on the
external network). However, I can ping the LAN side (172.18.0.88). 

 

Moreover, from a PC connected to the same LAN side of the router, I ACN
indeed ping all the way through the router to the external network and
beyond. I can also ping the server and if I enter 172.18.0.1 in the browser
I get Moodle. So in summary, the PC can send traffic through the router but
the server can't. Beats me but I am sure it is the network settings
somewhere.

 

I tried this using with the router LAN network set to 172.18.96.0/24 but it
didn't work either - I can't ping through the router even with a PC
(destination reachable). Note that the PC is given a mask of 255.255.224.0
by the XS DHCP (and DNS server 172.18.0.1) and it's not possible to use that
in the router settings.

 

Is this going to be possible? Do I need a better router ? I am going to the
remote site today for 7 days, and need to crack this one quickly

Hello all again,

 

A networking challenge this time.

 

I have an XS at a school where there also exists a wide area private network
connecting schools using Wi-Fi. We want those connected schools to be able
to access the XS, for various reasons.

 

That network (let's call it network 2) is 192.168.1.0/24 and it is connected
with the Internet via a router  running NAT and DHCP.

 

The XS local network seems to be quite complicated, I don't fully understand
it, but what I need to know is the correct slash designation for the httpd
and dns servers at 172.18.0.1 so that I can bridge it to network 2.

 

I am trying to use a Linksys WRT54G2 in DMZ Host mode with the IP address
172.18.0.1 bridged to the external Wan IP address of the WRT (set to
192.168.1.88)

 

The WRT LAN IP setting only allows netmask values of up to 255.255.255.0 and
I am worried if there is a mismatch then it could be why I can't get it to
work. 

 

I also suspect I may have to add something to the apache or routing config
on the XS, so as to listen on the WRT external IP address 

 

At the moment I set the Linksys to 

WAN - fixed IP 192.168.1.88 / 255.255.255.0

LAN IP address - 172.18.0.88 / 255.255.255.0  (could the net mask be the
issue?)

Application: DMZ Host, value 172.18.0.1 

Required changes to  xs apache settings   ??

 

Trying to connect on the network 2 side using a browser if I enter
192.168.1.88 or 172.18.0.1 it just times out.

 

If anyone reading this recognises what I am trying to do, I'd very much
appreciate your advice.

Re: [Server-devel] Bridging XS to another network

2010-10-30 Thread David Leeming
Thanks Anna, I'll just clarify;

 

I am working on UNESCO project where schools in a remote area are linked by
a WAN (both wired and Wi-Fi bridges). Only one school is an OLPC school.
Schools generally (not just OLPC) contribute to an online wiki environmental
encyclopaedia . Content in any kind of format is uploaded to a local server
where it is moderated and digitally processed if need be, by a trained QA
team prior to upload to the online wiki. This is needed for reasons of
integrity of content, traditional views on what content can be shared, etc.
Lesson plans are developed to support schools in ways linked to the
curriculum to access and create content for the wiki. Excitingly we can have
the OLPC uploading Sugar formats like eToys, etc. Other schools will
contribute text, images, audio and video. 

 

So the content will be locally uploaded to either the XS Moodle or the
offline wiki as appropriate - reducing barriers to participation. I have the
server running so that once you get access on a non-XO computer, you bring
up the Moodle using http://schoolserver/moodle andthe wiki from
http://schoolserver/wiki. It all works fine on the eth1 network (the
internal network). I can also connect any PC and enter 172.18.0.1 to bring
up the server Moodle page. 

 

It is NOT intended that XOs on the external network can register on the
single XS. The only school with XOs has local access to the XS on the XS's
eth1 network. The other schools only need to be able to  access the XS
Moodle and wiki.

 

So my problem is that even with opening and forwarding port 80, or using DMZ
Host mode, the server cannot see through the router and reply to requests.
On the other hand, a PC can ping right through the router so 

 

I just need in simple terms, to know what I need to do with the apache
config or hosts or other files so that the XS can be seen on port 80 from
the external network. I don't care about jabber etc. Only access to web
services.

 

I am packing to go now, but will look again at your advice - many thanks.
But if anyone can quite specifically give me advice on the router LAN
settings to use, and any required changes to the XS networking and routing
settings so that it is able to reply back to port 80 requests through the
router, I would be most appreciative.

David:

I'm a little confused as to your setup.  If you just have the one ethernet
device on the XS, it can either get an IP address from your router (as eth0)
or hand out DHCP addresses (as eth1).  It can't be in both roles.

I've played around with external access for the XS and it does involve some
firewall stuff.  I think I used lokkit to configure access to port 80 and
the jabber port to my regular LAN.  Then I opened up those ports on my
router firewall for access from the rest of the internet.

By way of example, here's a setup I've done in the past:

Regular LAN:
XS (eth0) 192.168.1.20
My Desktop 192.168.1.6
XO A 192.168.1.7

XS LAN:
XS (eth1) 172.18.0.1
XO B 172.18.96.2

On the XS LAN, XO B can go to http://schoolserver or 172.18.0.1 and see
the default Moodle homepage.  It can also register to the XS and all that

now manually set the Jabber server to 192.168.1.20 and collaborate.  If you
want to use Moodle, not being able to register to the XS is a huge issue.
Apache access works fine, though.

I use ifcfg-eth0-local to set the static IP for eth0 on the XS.  Here's my
example:

IPADDR=192.168.1.20
NETMASK=255.255.255.0
NETWORK=192.168.1.0
BROADCAST=192.168.1.255
GATEWAY=192.168.1.254

To see what I need to put in there, I'll do this on another Linux box

Re: [Server-devel] Bridging XS to another network

2010-10-30 Thread David Leeming
Anna,

 

What you describe below is what I am trying to do (see the net diagram in my
other email). I only want apache/Moodle/wiki to be available to the external
network (your regular LAN). You'll see that I have a simple WRT54G router
bridging but no matter what I try, I can't see the apache service through
the router. Can you say what Wan and LAN settings you used for your router? 

I used

WAN - fixed 192.168.1.88 / 255.255.255.0

LAN - fixed 172.18.0.88 / 255.255.255.0

Port 80 forwarded from WAN to 172.18.0.1 (or DMZ host with 171.18.0.1)

In this set up: 

If I try to ping from the XS to 172.18.0.88 it is OK, if I try to
192.168.0.88 it says network unreachable.

But if I use a PC hooked up on the eth1 network, with fixed IP 172.18.0.89 /
255.255.255.0 (for example) I can ping the WAN address and beyond. This is
what leads me to think it needs one extra step with route, or it may be
something to do with the WRT LAN setting and XS having different netmasks.
You can see I am reaching at straws a little L

There is one warning message that comes up on boot to do with the USB device

Yes, it does.

 My second question, is if there are any instructions on setting up a
 second interface using a USB Ethernet adapter.

I don't see any instructions, but I believe it just works if the USB

going last time I needed it, but I don't remember the details.

(a)In the attached document, MySQL Preparation, the stated directories

Background to his - I'm working on a project involving an OLPC pilot in
Solomons, rural community and schools wi-fi network, and a UNESCO indigenous

running on the same server as the XS. Then students using specially prepared

various reasons moderation is needed, and we also want to reduce any

Re: [Server-devel] PDA mambot on XS

2010-10-03 Thread David Leeming
Martin, Mike, 

I am exploring the possibility of increasing access to the server by
providing mobile-friendly content targeted at people in the community, and
the increasing number of phones with Wi-Fi support. For instance, the school
server as a multi-purpose resource could serve as a sort of on-demand
community radio station broadcasting audio information in the form of mp3s
(or any playable formats commonly used in mobile phones).  

It would be nice to have a tidy way to share such content, with user uploads
allowed too, and thus I thought of using a dedicated CMS with a mobile
extension or plugin. I understood by mambot that one could use a plugin
that causes mobile browsers to be recognised and then display content
tailored to suit. For instance, Wordpress comes with a mobile edition
plugin. On the XS it might run in parallel to Moodle with a different CMS,
and I am experimenting with that on an Ubuntu 10 machine, or there might be
a way to do it with Moodle. It might not be needed, I was happily surfing
the XS on an iPhone without any such reformatting. However, I want to see
what the range of options are, so I am interested in any feedback.

Is it possible to install a PDA-mambot on the XS without doing it via a

We had some results doing this , but it is actually much more time consuming
than installing and configuring the servers individually. What would be
really useful is (a) some way of automatic this or (b) the ability to export

Hi David,

super brief -

- get the machine in 'single user mode' (init 1 on the commandline will
work)
- plug new disk in, setup the partition table, and the filesystems
- rsync / and /library to the temp mountpoints
- remove hardware-specific files: /etc/udev/rules.d/70-persisntent-net.rules
- fixup /etc/fstab to match the UID of the new filesystems
- run grub targetting the new disk
- move new disk to new machine

that will _clone_ the XS so it will keep a lot of identifiers (and all
the data) from the original XS.

Do NOT use this technique for cloning a base install. Use
kickstart/anaconda methods to automate many-machine rollouts.

Re: [Server-devel] wifi setup

2010-08-04 Thread David Leeming
Tom

We use multiple APs in schools set up in simple AP mode, using DHCP (not
fixed IP), the same SSID exactly, and only one network icon appears in
neighbourhood view. Same capitalisation is important. But you never have to
choose which one it should connect to. At the current school we had to
accept some 120 sector APs as there was no omnis in stock. Walking about
with Terminal Activity running and pinging, you could clearly see where it
hopped onto a new AP.

Can't add much more from technical point of view. We've used Linksys W54
types, EnGenius various types, DLink cheapo and more expensive types, and
usually in the default state with minimal config - just SSID, simple access
mode and DHCP client. Everything on the eth1 network.

Great idea on the digital timers -- when you have a chance, documenting
the setup would benefit other deployments.

Will be posting up details on wiki pages when I get a chance. But we are
using Sundaya S4 kist with the 55W panels doubled up with 2A loads or less.
The units are self contained, well priced, and the system is modular so that
if one part goes down due to low voltage it doesn't pull the rest. So far we
have seen the unit with the server (1.5A load) running all night reaching
full charge by 11am even on a cloudy day. The 12V DC digital timers were
sourced from Rainbow Power, www.rpc.com.au)

 (Advice on power management): I would like suggestions how the server can
be
 safely turned on and off automatically.

I have designed the server so that it survives sanely hard power off.
 During development and testing I almost never issue a formal shutdown.
 Removing the powercord is de rigueur.

Just don't do it during yum / rpm updates (how I wish those were saner!)

OTOH, given that you have set timers, if everything is running smooth
you know what time power will be off, so you can set a cronjob at a
regular time to run shutdown. (As various clocks drift, this won't be
particularly reliable...)

Daily reboot _not_ needed.

OK, well we have set it up to run 24/7 with the timer override, allowing
teachers to set the timer to auto if need be (but then they will have the
daily task of manually switching it on, that can get neglected in my
experience, especially as the servers are in locked rooms, with the daily
hassle of finding keys etc. Sounds a minor issue but in practice it is best
to have the system as automated as possible).

We also added a line to the cron table (crontab -e) to have a daily reboot
just because we have been brought up to think that is a good thing!!!

 ... generally the
 impression was that networking was functioning well over the entire
campus.

Excellent!

 However, we noticed that collaboration was not working well. XOs could not
 see all members of their course in neighbourhood view – it seemed to be

I would have expected that. The ejabberd server (if you've updated the
RPMs to the latest from olpcxs-testing) will handle many XOs well, but
the neighbourhood view on the XO doesn't cope well with so many XOs.

The cure: segregate presence by course (see xs techniques and
configuration in the wiki for the steps).


We reconfigured with smaller groups (less than 35 per group) and it tested
OK - 6 class groups all independently collaborating and isolated from each
other. As it was the last day and Sunday, we could only do a limited test
with 5 XOs per class but we had Chat running with pretty good responsiveness
(the icon appearing in a few seconds on all laptops) on each of the 6
classes. Whilst this was happening I measured memory use as 184KB total
using ps_mem.py up from 170KB with no XOs active. We'll have to wait for a
monitoring visit to get the data on the full load situation. We only had 2
weeks to do all the training and obviously focused on laptop use and
classroom integration / the pedagogical side, although one teacher was
trained to do basic user management on Moodle. These teachers have mostly NO
previous computing experience.

[Server-devel] Server performance feedback and testing suggestions

2010-07-30 Thread David Leeming
In our PNG deployment we have only just got the system up for testing due to
late delivery of most of the infrastructure eqt (we had the laptops so were
able to complete the initial training);

-  250 XOs divided into six classes G3A - G5B and all 15 teachers

-  One eBox fanless VIA server with 1GB RAM (non-expandable). We had
planned two (one for G3-4 and one for G5+) but vital eqt did not show up in
time so we are managing with one.

-  Campus wide wireless network, solar powered, using a ratio of less than
30 XOs per AP.

-  1Gb switches used throughout

-  1:1 use of 15W thin film (GoldPeak) panels with DC Share cables for the
laptops. No power in this school.

 

I have questions about power management for the server, and feedback on
server performance.

 

Layout is 3 x single storey double classrooms (G3A, 3B... 4A, 4B...etc) in
line, separated by about 15m. The server is situated in a parallel line of
classrooms about 6m to one side. We use some centrally located solar power
supplies with POE. The whole system is DC powered and we use digital; timers
to turn things off when not needed to save power. However the system
provides good access for at least 15 hrs per day.

 

(Advice on power management): I would like suggestions how the server can be
safely turned on and off automatically. I guess auto off at an agreed time
would be easy, turning on might be hardware dependent. Or can we put it into
sleep mode when not needed (10pm-7am) and have it running 24/7? With solar
power one has to be efficient as possible. If it is run 24/7, we'd like to
know how a timed daily reboot can be activated, and whether that is a good
idea or just leave it on.

 

(Advice on server performance and testing suggestions): 

 

We only have 2 days to test the full system due to the crazy logistical
issues that have plagued us. Yesterday we had it all running with the
students in the classrooms, logged on to the server OK. They are segregated
into 3 courses at the moment (G3, G4, G5) with about 60 students per course.
However in the test yesterday it was out of school hours and only maybe 30
students per course (Grade) were present. We observed that browsing the
server, both with site files and public folders (such as Schools Wikipedia
and the heavier UNESCO ASEAN SchoolNet series of flash animations) was
generally working good and the server as responsive. Moodle admin (such as
adding users to courses) was working very responsively. So generally the
impression was that networking was functioning well over the entire campus.

 

However, we noticed that collaboration was not working well. XOs could not
see all members of their course in neighbourhood view - it seemed to be
taking a long time to populate the view, and you could see some dropping out
occurring - XOs that were on and connected, suddenly disappearing from view
on a neighbouring XO. Likewise, sharing activities was almost universally
not working - no icon displayed on the course members neighbourhood view.
This contrasts with the good responsive and reliable browsing. In this test,
we were using presence service split by course, with the students added as
students and the teachers of those grades added as teachers. No-one was
given site roles. The teachers were also members of another course
teachers intended to allow collaboration between the teachers in different
grades.

 

We would like some feedback on what could be the issue. Is it the low power
server with only 1GB RAM? But we only had a maximum of about 90 students
divided into the three courses online yesterday. Could it be some
inefficiency in the networking? But browsing was working well. Could it be
that Moodle is broken in some respect? But during training we were
experiencing no issues with collaboration with the teachers.

 

What data , logs can we collect to analyse the performance and feed back to
this list? 

 

Thanks.

Re: [Server-devel] Turn Editing On missing and joining multiple courses

2010-07-30 Thread David Leeming
Martin,

My request is about the Front Page. In courses it is clear how to manage
editing. On the Front Page only the first XO seems to be able to create
global links to public folders and site resources (the menus that become
editable through Turn Editing On). It may seem a point of detail but what
happens if the first admin XO becomes unavailable for any reason? We are
told that logging on as administrator is at your own risk as it might
break Moodle. As the persons who would be required to log on as
administrators would be the teachers only newly introduced to computers, I
think we need to follow safe guidelines.

Yes - perfect! You're getting the 'moodle way'. Create a Teachers'

 expect – will there be any “cross over” issues (the best way I can
describe
 it) if teachers A and B are members of the Grade 3A and 4B courses
 respectively, and then also both as members of “Teachers”.

Each course its is own world -- you are doing it right.

Moodle never asks is this person a teacher? or is this person a
student?. Moodle doesn't care. You are a teacher _in the context of a
course_. You might be a student in another course (how to use
moodle)!

A child might be student in a course, but an openminded teacher /
course creator  can setup a course where kids are setup with a
teacher role and can do more things!

Hope all is good in PNG!

Re: [Server-devel] [Fwd: Turn Editing On missing and joining multiple courses]

2010-07-28 Thread David Leeming
Thanks Tabitha,

 

I realise I should be clearer about what I am asking. I understand the
Moodle context-based administration. It is rather the effects of multiple
course membership on the presence service when split by course, which I am
uncertain about. Let's say user A is a member of course 1 and course 3. User
B is a user of course 2 and course 3. Does that mean that user B will be
able to see all the members of course 1 as well as user A? I don't see
evidence of that in our deployment but I am just checking in case this could
cause issues with the presence service.

 

We are using low-power (and low-RAM L) servers due to our dependence on
solar power. So we need to make it work most efficiently and as I understand
it, that is best achieved with small user groups segregated using the
presence service.

 

Regarding the other matter; logging on as Administrator is according to XS
Techniques and Configuration a non standard task at your own risk. I am
trying to use standard recommended procedures, which can be safely
replicated by the local trainees, using the first XO registered - which is a
partial administrator (it can create course creators, but cannot delete
courses). If I create a course creator with that initial XO, they do not
have turn editing on appearing which means that they cannot (for instance)
create global links to public folders on the front page - even if they are
Front Page course creators too. 

 

My question in regard to this issue is whether what I am observing is NOT
what I should be seeing, and there is a problem with my system, or whether
your inference is what I should be noting in that you have to actually log
on as the site administrator to create a full replica of the first XO.

In our PNG deployment and elsewhere I am finding with Moodle that when the
initial administrator XO creates additional course creators, the Turn
Editing On button does not appear on the new Course Creator XOs, although
you can see all the site admin functions. For example, I have used Admin 1
XO (the first one to register) to make Admin 2 XO a system course creator
and a front page course creator.  But no Turn Editing On appears. 

I don't know exactly the role setup for Moodle on XS, but it may be that
they have slightly different roles; do they appear at the same level in
Users - permissions - assign system roles?
I just tested - I am logged in as site administrator (I mean Moodle role
administrator at system level) on one computer and have just assigned
another XO as course creator at system level. The new system course
creator XO does have a turn editing on button.
Tested adding another XO as a front page course creator and this XO does not
get a turn editing on button. I then tested assigning the XO as a front page
teacher and now they do get the turn editing on button. 

Secondly, we have set up courses for each of six classes and are joining the
250 students and their teachers to them as teachers and students. The
teachers have been made Front Page teachers but not been given any system

respectively, and then also both as members of Teachers.

The PNG teachers can be in a course called teachers and assigned as any role
you want. I think the front page thing might be what is confusing things for
PNG. Moodle is hierarchical - system roles beat course roles which beat
resource/activity object roles. Moodle considers the front page to be a
course, so system role would beat it. 
PNG Teachers are not system level teachers so you can make them students in
a course. Who is the teacher role assigned to for the teacher course? The
principal maybe?  
Continuing this train of thought - it is perfectly okay to make a student a
teacher of a course. e.g. You can have a year 6 student the teacher of the
year 4 maths course if you want. Just don't do it at system level, stick to
course level. 

I would not set system level roles for anyone except the person(s) who will
adminstrate Moodle after you leave. Two people is good in case one person
leaves.

[Server-devel] Turn Editing On missing and joining multiple courses

2010-07-27 Thread David Leeming
Hello,

 

In our PNG deployment and elsewhere I am finding with Moodle that when the
initial administrator XO creates additional course creators, the Turn
Editing On button does not appear on the new Course Creator XOs, although
you can see all the site admin functions. For example, I have used Admin 1
XO (the first one to register) to make Admin 2 XO a system course creator
and a front page course creator.  But no Turn Editing On appears. 

 

Is this an issue or something with my system? I have noticed this before and
we have just set up the server in question from the default image with
minimal configuration changes. It has the most recent testing updates. XOs
are 1.0 / 802 / 0.82.1

 

Secondly, we have set up courses for each of six classes and are joining the
250 students and their teachers to them as teachers and students. The
teachers have been made Front Page teachers but not been given any system
roles (otherwise they appear in all the courses). We want to allow teachers
to collaborate between each other as well, so I am thinking of creating a
Teachers course. I have not enough experience with Moodle to know what to
expect - will there be any cross over issues (the best way I can describe
it) if teachers A and B are members of the Grade 3A and 4B courses
respectively, and then also both as members of Teachers.

 

Many thanks from Central Highlands, PNG

[Server-devel] Creating Moodle administrators

2010-07-19 Thread David Leeming
My question is whether the initial laptop to be registered on an XS has full
administrator rights? I am finding it difficult to delete courses. Should I
be able to do so? Moodle documentation states that only Administrators - not
Course Creators - can delete courses. However, as  one can use the first XO
to upgrade other users to Course Creators, that would imply that the first
laptop is indeed an administrator. So where should I find the delete
course function? 

 

We were hoping to create master images of our configured servers for a
multiple school project. But as far as I see it, we need to use a registered
admin XO to configure Moodle in the first place. Is it possible to remove
this after configuring Moodle, so that we can make clones which will then
accept the next laptop as their admin user?

Re: [Server-devel] Offline update

Good, Martin

Is it possible to download the updates from a Windows machine? We want to
update a server which has the stable 0.6 version 7th Oct 2009 to benefit
from all the latest patches etc, and then create a master image to use with
a few others. 

For a while we don't have access to a direct Internet connection or a Linux
machine - only expensive (USD 25c per MB) hotel wireless subscriber systems.
I need to download any update rpms and transfer them to and run them
manually on the XS.

Yes!

You can download all the RPMs, put them in a usb stick and then take
them to the target offline XS.

If you want to download the exact RPMs, take a similar XS that is
connected, and do

 yum [maybe --enablerepo=olpcxs-testing] update

and look at what it proposes to update, then run

  yumdownloader [maybe --enablerepo=olpcxs-testing] packagename

If you don't have yumdownloader, it's in the yum-utils package.

Re: [Server-devel] How to access site files quickly?

2010-07-05 Thread David Leeming
I am sorry, I sent this prematurely. Can I add some clarity

As I understand, OLPC is build on the principle of openness. When the
technology turns on itself and prevents the positive impacts, we must look
again at it.

We have some bona fide requirements to do what I am asking, in real life
situations attempting to build the capacity of national education
departments in my region, and we can't allow the technology to set the
agenda. It should rather enable what we need to do with the skill set/pool
that is available.

The server is nothing without content - and we have to make it easy to share
content (including uploading ad downloading without rigid contextual
frameworks)

Hi David,

My understanding is that bulk upload is typically discouraged because
each upload needs to have at least one context (context of a course,
assignment, etc) whereas a bulk upload simply throws all files into a
folder. Having said that, here's what I found.
http://www.moodleblog.org/?p=178 Both the video and the comment on
this page points to the same caution of bulk upload. Maybe Martin can
point to something better?

Re: [Server-devel] Educational XHTML Editor Educational Game Maker

2010-05-19 Thread David Leeming
Mike,

I have followed eXe Learning since it started, developed by Wayne Mackintosh
who later on, of course, created the WikiEducator and is a leading champion
of OERs. I can instantly see that eXe Learning if installed on the XOs would
be a very useful tool. Very easy to train teachers to become productive
quickly, compared with, say, online wiki work, which is not always an option
(yes we can install mediawiki on the XS but I think eXe Learning has
specific advantages in some areas). It is very well targeted technology,
thinking of the OLPC deployments in which I have been involved. As an
example, in a distance learning programme here in Solomons in 2007 we
converted examples of teacher training resources into online format using
eXe Learning, in order to demonstrate simple first steps in e-learning to
the Ministry. A junior officer with only basic office computing skills was
able to migrate the entire RTC teacher training manuals to online with
limited supervision - and she enjoyed it too!

Of course, the resources produced with eXe Learning are HTML based which are
easy to install in public folders on the XS. eXe Learning can also output
SCORMs which can be loaded into the XS's Moodle as appropriate. 

If we had access to an eXe Learning activity I would immediately incorporate
it into the teacher training that we do in Pacific Islands deployments.
Empowering teachers to create and share resources is always a key component
of Level 2/3 training, linked to curriculum integration. OERs have massive
potential for the Pacific. Educators have repeatedly called for more
regionally relevant and localisable curriculum related content, and
empowerment of front line teachers to create OERs is the way to scalability
- freeing up the dependence on overworked curriculum departments locked into
traditional closed authoring approaches with long term donor programmes.
Resources created with eXe Learning by teachers with XOs will therefore have
a wide currency beyond the OLPC project areas which are still only small
scale. They can be shared and used freely.

So, I will watch this thread carefully. I would like to help, if not as an
active team member on the coding, in other ways. What is the status of this,
can we expect an eXe Learning project for Sugar and the XO?

One requirement would be to be able to create a resource using the eXe
Learning activity, name and save in journal, then to be able to upload it
to the server so that it is installed as a public folder (or via site
files etc) but without any difficult command line work needed on the
server. So needs to be coordined with XS-devel.

Subject: Educational XHTML Editor Educational Game Maker

Dear List,

One of the greatest challenges here in deployments has been to create
sufficient curriculum *interactive* educational content.  Though
Scratch and Etoys are great for simulators for many common educational
interaction formats (e.g. assemble objects, click in place according
to hint in order, memory match, hangman, sorting items etc) using such
tools can be quite awkward.

eXe Learning was created as a GUI educational XHTML Editor with
support for fill in the blank question formats, multi choice, multi
select etc.  I have created plugins for Place the objects / label
(e.g. assembling parts / labelling a diagram), Click in place
according to a hint, sort objects, hangman, memory match, moving
object speed answer (e.g. Tuxmath) and sort.  The output is generated
as HTML / Javascript which can run online or offline.  I've also
created a plugin for embedding Scratch using the Scratch Java player
with an option for the user to download.

There are many repositories of open content; however many of them fail
to harness the potential of ICT as an interactive medium.  Hopefully
further lowering the barrier can help to create more.  This can make
it far easier to turn existing open static content into interactive
educational content.

Compared to conventional Javascript / Flash / EToys development this
dramatically increases the amount of educational interactive content
that can be produced by given teams in a given amount of time.  It
also can help make creation of interactive educational material far
easier for educators by templating the kind of interaction they would
like to produce and allowing them to just plug in the questions,
answers, images, options of the game etc.

For many parts of the curriculum the best course of action can be to
embed already created Scratch simulators from the Scratch website
(e.g. physics sims).  With eXe Learning + plugins one can produce a
complete interactive package that opens in the browser.  I am hoping
to develop a roleplay and generic simple simulator creator in the near
future.

Yes, the moodle feature is called site files, and should be
available (at least) to the first course creator.

In fact, it should be available to every course creator, but you've
hinted at some symptoms of a config bug that could be affecting other
course creators. Can the first CC see this option? Can other CCs?

[Server-devel] News forum and user database

2010-05-04 Thread David Leeming
I have two questions, we are deploying at a school in PNG this week.

 

1)  What is the easiest way to take home with us (i.e. on a flash-drive)
a copy of the user database with names and serial numbers of XOs registered
on the XS? Where is the database?

2)  What is the expected behaviour of the default news forum on the XS
Moodle front page? We registered an admin XO and then a load of users. I
tried to add a news announcement using the admin XO. It appears on the admin
XO but none of the users. In an earlier test with another XS I noticed this,
and went into the forum settings and forced everyone to be subscribed and
tried other options but I could not get it to display the forum postings on
the user XOs.

3)  What sort of data would people find useful from the server
performance? We have a small form factor eBox as the server (sorry I don't
have manufacturer details, I will try and get them) with five access points
distributed around the school. Situation is that there are initially only 61
students (G3 and G4 - PNG primary schools start with G3) and 8 teachers with
XOs, but on saturation we will have 170 students (may have to add another AP
or two). So this week we can test how 70 XOs perform in that environment. We
will have them in two Moodle groups with the presence service split my group
(G3 and G4).

Note on power consumption: We have ascertained that the eBox uses 14W and
the whole set up runs at 45W. In this school they have daytime power but in
the other 12 we are doing they will need solar power.

 folders to be listed. I.e. if there is no specific html file, the whole
 contents of the folder appear in the browser. Fine that is what I want.



 However, when copying content into that folder I rapidly run out of space.
 It seems that the main disk space is in an another partition where the
 folder /library is located. This makes sense (i.e. to have a lot of room 
 in
 the library...)



 Therefore, I copied my public content into sub folders under the directory
 /library and made the whole of /library public using the html.conf file 
 with
 Aliases pointing to my specific subfolders.



 However, under /library it won't allow contents of subfolders to be listed
 (unless there is an index file in which case it opens that by default, but

 I
 want the folder contents listed in some cases.



 Help?

Re: [Server-devel] PDF resources in public folders not opening in Reader

2010-04-03 Thread David Leeming
Having established that there is a bug in the PDF plug in for Browse 102,
with filenames having spaces, we can assume when that is fixed it will be
fine. I do have a question, how will the two options (Browser plug in, or
download and Read) compare in performance in a situation with say, 30
students reading the same pdf book from the server. Does the plug in
download the entire file before displaying? I.e. when it says Loading is
it loading the local copy? Would that slow down if there was a full class
engaged in the same activity?

 Hopefully an XS expert might be able to answer this.

 In the Browse activity that you are using, it doesn't seem possible  
 for
 the user to force a download.

I don't believe this is an XS issue. The XS is serving up the file and  
correct file type. I believe the solution lies in altering the mime  
type on the XO, so the XO will download the PDF and associate it with  
the Read application. FWIW, this is exactly how Browse used to work  
and it was altered so Browse would open, the pdf rather then having  
to launch the Read activity.

Investigating further, the resource in question opened in the browser
successfully when I shortened it's file name. Lesson learned is that long
file names cause problems ?

We have many resources that are published in PDF that we want to make
available in public folders. However, when you browse to them and click on a
PDf file, it does not open in Reader but within the browser and I am finding
that the PDF reader plug-in for the Browse activity is not able to open many
of the files - it just tries then chokes with a blank screen. Not particular
large files either (3MB or so). The same files open perfectly well with Read
activity from the Journal. 

 

So, how can we get it to force downloads that then open in Read activity?
There is a check box force downloads, can we make that take affect
globally in the public folder?

Re: [Server-devel] Turn editing on is not available

2010-03-30 Thread David Leeming
Hi Andra,

 

I haven't received any other feedback on this yet, so thanks for this. I
will try it but am worried by the warning given. What we are doing is
building a master XS to be cloned for up to 20 other servers. So rather
than have that risk multiplied by 20 it may be best to rebuild it completely
to get back the turn editing on facility that we have lost, unless Martin
or others can advise.

 

To restate, we had made a couple of changes to the System Roles to reassign
the main admin XO. That was fine, but in the process we now find that turn
editing on does not appear on the home page of the assigned Course Creator
XOs.

Any tips welcome.

 

David, I'm not sure if you got an answer or not. I am new to this, and I'm
not sure what caused your issue, but if you log into Moodle as admin, then
under Users / Permissions you will have the capability to Define roles.
Under Course creator at the right side, you can edit the roles. I was not
able to do this from my XO as mentioned at the bottom of the Wiki clip
below. I was able to do it from a non-XO by connecting to the AP and using a
browser to login to the schoolserver with the information given below.

Wiki excerpt


Logging in with the admin account


Use at your own risk! Direct access to the admin account is not recommended.
It may break your Moodle-on-XS today, or it may lead to breakage on
upgrades.

.. Normally the account is disabled (and only enabled at upgrade
time). Enable the account with

sudo -u apache php /var/www/moodle/web/local/scripts/adminuser-enable.php

.. After each upgrade, the account will be disabled again.

.. Look at the password - it is different for every XS:

cat /etc/moodle/adminpw

.. Login with the username admin.

.. If you are logging in from an XO which auto-logins using your
registered account, you can access the login page directly by editing the
URL to say  http://servername/moodle/login/
http://servername/moodle/login/. You can use this form even if you are
logged in.

Re: [Server-devel] Turn editing on is not available

2010-03-30 Thread David Leeming
Martin,

We have tried everything given there, and can happily add and remove Course
Creators.

But none of them can edit the Front Page because turn editing on does not
appear. We only have one half day left so unless we fix this we will revert
to plan B completely rebuild the servers - frustrating.

We also tried changing Front Page roles, to add the Course Creators within
that context. But to no avail.

Any idea where the config for editing of front page is located?

David

Hi David,

I am a bit snowed under, and unable to give you a good response
quickly. I think it's a logic bug.

I am pretty sure, however, that the problem you are seeing will
disappear if you use the technique here:
http://wiki.laptop.org/go/XS_Techniques_and_Configuration#Controlling_Course
_Creators_directly

Hope the workaround works for you. If you are deploying many XSs and
you know what XO you want as main admin, that will work for you.

cheers,
