Running on the ARM platform, I get:

Re: [Server-devel] Problemas con servidor xs

[Reuben K. Caron]

Fernando, Carlos,

Hola Amigos.

First, we'll troubleshoot this and then I'll tell you why this setup is 
problematic.

2wire: 192.168.1.254
XS: 192.168.1.253
XOs: 192.168.1.0 -- > .252

On the XS:

-Did you save the static ip changes to the file: 
/etc/sysconfig/network-scripts/ifcfg-eth0-local?
-What is the output of the command ifconfig -- Does it show that the static IP 
address configured correctly?
-What is the output of the command ping schoolserver
-What is the output of the command ping 192.168.1.254
-What is the output of the command dig google.com
-What is the output of the command ping google.com

On the XO:
-Connect to the Wireless.
-What is the output of the command ping 192.168.1.254
-What is the output of the command ping 192.168.1.253
-What is the output of the command dig google.com
-What is the output of the command ping google.com
-What is the output of the command ifconfig -- Note the IP address of the XO

On the XS:
-What is the output of the command ping IP_ADDRESS_OF_XO_ABOVE

Your current setup has limitations:
1.Only 252 clients will be able to connect
2.XO's cannot connect, ping, or resolve "schoolserver," DNS entry because they 
get IP configuration from DHCP of 2wire. 2Wire does not know how to resolve the 
hostname schoolserver. 

The #2 issue can be resolved by either:

-If possible you maybe able to assign the DNS server in 2Wire configuration to 
point to 192.168.1.253 for DNS resolution, *or*
-Disable DHCP on 2Wire, Enable DHCP on XS, Add manual default routes from XS 
<-> 2Wire

Let us know the output of the commands and also some screenshots of the 
available configuration of the 2Wire configuration screens because I cannot 
find any manuals available online for this model.

Regards,

Reuben

I believe OOB is pulling activities and version information from here:

Update the links to the latest version and on the next build you should get the

Can we make it so that it only installs signed RPMs? Would that help?

I signed manifest which includes a list of files would probably be  
more feasible as you wouldn't have to alter the RPMs.

Re: [Server-devel] Dansguardian on XS

[Reuben K. Caron]

German,

You are at a point where you must define your own public DNS server.  
Hosted at your own public IP address. On the following site we show  
the technique. The configuration is not exactly the same but similar:


http://wiki.laptop.org/go/OS_Builder/Adding_OpenDNS_Configuration#Configure_your_public_DNS_server

Basically, DNS queries would be: XO->XS->PUBLIC FOUNDATION DNS SERVER- 
>OpenDNS


As your deployment grows this will also allow you to more easily scale  
your XS installations as they can be preconfigured to point to your  
managed DNS server, instead of trying to find the public IP address at  
each site.


I hope this helps.

Regards,

Reuben

OLPC's keys will always be installed and valid unless the customer chooses to 
override. From what I understand, you're planning to only use augment keys so 
Tony's comments are still valid.

Re: [IAEP] "Mesh" Dreams = OLSR

[Reuben K. Caron]

Mike,

Thank you for the information!

To be clear, from what I understand from our discussions in the past  
you're topology looks like

AP(802.11A + OLSRD) - AP (802.11B/G) - XO

You have several AP(802.11A + OLSRD) acting as your backbone and they  
drop down to standard AP (802.11B/G) for connection to the XOs.

Please let me know if this is correct.

Out of curiosity: have you considered extending your OLSR network to  
the AP (802.11B/G)'s and installing the OLRSd binary on your XOs so  
the OLSR network can be extended beyond the school?

Thanks,

Reuben

Here is a link to a paper that actually tested in a physical 49 node

This differs from most other papers that I have read that use

Fo deployments that have funding for APs there is not much need for  
"mesh." I would approximate that roughly 66% of our user base are in  
deployments that do not have funding for APs.

 From what I understand, OLSR has a better mechanism for maintaining  
the "mesh information." If you recall any change in mesh was  
previously broadcasted to all listeners. OLSR is configurable. For  
instance, information would only be broadcasted to two levels of one  
devices immediate neighbor not the whole mesh cloud. Another issue we  
had was maintaining mesh information in a limited memory space on the  
WLAN module; OLSR would now process that information.

Hi Chris,

Great point. Thank you for bringing this up. I have given this some  
thought; though I'm curious to know if this is your only objection to  
the suggestion? I find it interesting that what you consider a non- 
starter, I consider a feature. I have often considered it a bit  
presumptuous for us to deplete one child's precious power resources to  
maintain the mesh network for other children. We have created a model  
where in essence one household is funding access to the Internet in  
another household through power costs. My thoughts are: we don't do  
this. If the XO wants to go into idle-suspend let it. The connecting  
XO will have to find another path or lose access to the Internet.  
Either way it is a better solution then what we have now. If children  
group together and knowingly disable idle-suspend so they can maintain  
a mesh network for their neighbors then that is fine and a great  
example of building community but doing so as a mandatory  
implementation IMHO and with all due respect is questionable.


Some things I'd like to point out.

-8.2.1 has idle-suspend disabled by default and we are considering  
disabling by default idle-suspend for new XO - 1 builds. In these  
cases OLSR would be performing fine.
-The switch in WLAN chip from XO 1.0 to 1.5 forces us to re-think how  
we do connectivity.
-The thin-firmware being built for XO 1.5 has the same CPU-prohibiting  
idle-suspend limitation and *does not* include a user base and support  
community of thousands of users and active development. Yet it relies  
on one closed source firmware developed by one firm based on the same  
"mesh" technology developed 3 years ago. It also lacks my hardware  
agnostic points.
-On the XO 1.5 builds where idle-suspend is working (CONGRATULATIONS  
TEAM), I'd recommend letting it idle-suspend. Yes, it will create  
route-flapping but in the school scenarios there should be enough  
paths to maintain connectivity and in the household environment any  
bit more of connectivity is better then none. It also leaves children  
and families the ability to knowingly disable-idle suspend and provide  
a resource to their neighbors.


Thank you for your thoughts.

"Mesh" Dreams = OLSR

[Reuben K. Caron]

Where Mesh != 802.11s but rather an adhoc, self healing, self  
organizing routable network.

Imagine a world where Sugar on a Stick machines can communicate on the  
same network as an XO laptop. A world where mesh capabilities are  
hardware agnostic allowing anyone to bring up a mesh network by  
booting a live cd.

Imagine a school full of XOs where some are connected to Adhoc Channel  
1, some to Channel 6, and some to Channel 11. Now think of an XO that  
has two USB Wireless Adapters each connected respectively to one of  
those channels. This central XO also has a third USB ethernet dongle  
or a 3G wireless modem attached to it. Consider how this simple setup  
could provide Internet to everyone in the school. Consider the ability  
to actually create "Mesh Portal Points," that allow one connection to  
provide an Internet connection to many hops down the line.

Consider the benefits of using open source software versus our closed  
source firmware and partnering with communities like Freifunk whose  
network is ~ 800 node, guifi.net is almost 10k nodes in Barcelona,  
Athens Wireless is 5k nodes.

These things are all almost immediately possible by using OLSRd  
software. Over the past few months, I have tested and built small  
networks around my neighborhood to consider the feasibility of such  
software. Now I realize there is a difference between small and large  
networks but I think it is something we should consider.

As I have said, please *consider * all of these things with a fresh  
perspective and try to forget about the prior mesh battles.

Let's think of solutions that will actually make this work.  Some  
things to consider from Aaron Kaplan, a member of the OLSR community,  
cc'd here:

"How to scale networks?

-The key is to have multiple channels, smart channel selection/ 
assignment, automatic txpower control and low interference between  
nodes!
-In a sense, it is funny but true: the quieter the devices become, the  
better everybody can "hear" his mesh partner.
-Summary: layer 2 is king for scalability , only then do you need to  
look at layer 3 optimizations (and with OLSR.org we already took care  
of that part"


I hope that we can come together to re-group and re-think how we OLPC  
and SugarLabs do connectivity and utilize the open opportunities  
available to create such solutions.

Reuben

Redesigning: Library, Read, Get-Books, and Content bundles

[Reuben K. Caron]

There has been a lot of great progress with the Read and Get-Books  
(IA) activities. However, we have neglected to think about how we can  
better fit all of these pieces together. For instance, consider  
deployments that would like to install content bundles. They package  
these files into .xol packages and these packages get installed into  
the "Library," which is contained on the left hand side of the Browse  
activity. Yes, you read that correctly..."the BROWSE activity," an  
activity intended for online exploration is used to view offline  
content. Every deployment that I have shown this to has found it very  
unintuitive. Consider another example: You want to use Get-Books to  
get a new book. So you open Get-Books search for a book and download  
the book. But where did it go? I guess one could assume (correctly)  
that it went to the journal. So you close Get-Books. Go to the  
Journal. Find the book you downloaded. Open the book (in Read.) IMHO,  
a series of needless steps.

So what if we created a "Library Activity"
The activity would:
-Open a book from within the activity
-Highlight and annotate books
-List all of the books you have downloaded
-Allow you to search and download additional books from Feed Books,  
Internet Archive, the XS, etc..
-List the resources in /home/olpc/Library (so this can be removed from  
Browse)
-Allow one to synchronously or asynchronously share a book to their  
Neighborhood so anyone can download and read it.

I have filed a bug here if anyone would like to follow it: 
http://bugs.sugarlabs.org/ticket/2110

I look forward to hearing your thoughts.

Regards,

Reuben

Good question -- no there wasn't.

But the f11 builds for xo-1 only did 802.11b/g for a long time. I  
have

this silly assumption that there's a kmod to blacklist or a kmod
option to set/change to completely disable the 802.11s support.


As far as I know, there is NO way to completely disable mesh
support on XO-1 without holding the WLAN card in reset.
Even if you don't support it at the OS level, the firmware will
still behave badly if it receives a mesh broadcast packet.

IIRC, we settled for trying to ensure that no mesh packets were
ever broadcast, but if one did get sent, everyone would still
help relay it.



Um, I think this should send a mesh stop command to the firmware.

Re: [Server-devel] Fwd: [SoaS] wireless connection school server

[Reuben K. Caron]

David,

Keeping the list on.

So to be clear the XOs are connected to an Active Antenna and the SOAS  
is connected to an AP?

How is the AP connected to the XS?

You are correct the original intended audience for the article was the  
G1G1 community; however, the fact remains that it continues to be the

5 minutes...then why hasn't it happened?!?! Oh I know! The barrier to  
entry for writing an activity is too high and, unlike Flash, a  
relatively small number of people know how to do it...If flash were  
more widely supported on the XO, I'm sure such a Flash APP would  
already exist.

I'll refrain from listing the software on the XO that is nowhere near  
possible to edit on the XO because either the source code is not  
available or the XO does not meet the technical requirements to run  
necessary software.

Yes and no. Anyone technically capable to rebuild our build system, as

AIR.

No again, OLPC should have done the legwork so deployments don't have  
to jump through the hurdles of obtaining licensing from Adobe.

Carlos,

+1

Thank you for bringing this up.

FYI: One of our largest deployments and two other smaller deployments  
have received approval to ship Adobe Flash in their builds.


IMHO, OLPC would be able to provide deployments with the option of  
including Adobe Flash, while continuing to include Gnash as default,  
if they wish to do so without having to jump through the hurdles of  
applying and waiting for individual approval.

Message-ID:

Hi guys.

I know most people here prefer free as in Libre as opposed to free as
in beer, but what do you think of coordinating with Adobe to get Flash
10.1 + AIR 2.0 on the XO?

Adobe already supports a lot of open-source initiatives and have
already open-sourced the Flex SDK which you can use to compile SWFs
using text files and a command line a la JDK (or in Windows, using an
open-source IDE like Flashdevelop (needs .NET runtime)).
http://opensource.adobe.com/wiki/display/flexsdk

Flash's spec is open, but they cannot opensource the Flash Player or
AIR because they contain technologies which Adobe does not own but
pays licensing fees for.

With stuff like Youtube (using the camera to record a video, something
you cannot do with HTML5), UStream and games (which kids dig a lot),
the internet experience really isn't complete without Flash.

Moreover, the big difference is that with the Actionscript Virtual
Machine 2 which uses Actionscript 3, the speed difference from the
AVM1 (Actionscript 1/2 like GNASH) is 10x or more, which is very
important since we're talking about low-speed/power devices here.

Also, Flash Player 10.1 has been engineered for mobile devices so it
should run very efficiently on the XO 1.5 (you can only do so much
with the XO-1, but Flash 10 beats GNASH's performance on it
nonetheless).

Also (sorry John, Rob), Actionscript 2 is a dead technology which
needs to be put to rest (and there are few practical open source tools
to generate AS2/AVM1 SWFs). GNASH simply cannot catch up with the
features that are being implemented with each new release of Flash..

Also, Adobe is actively pushing Flash on as many devices as possible
via the Open Screen Project http://www.openscreenproject.org and I'm
sure they'd be more than happy to have Flash get bundled on the XO.

Also, Flash is the most commonly used toolset for building educational
apps. Not everyone has the skill or patience to programmatically
animate objects in e-learning applications. What I mean is that it's
very efficient.

What do you guys think?

Hello everybody.

I'm volunteering at CeibalJAM [0].

I'm trying to make Java applets work in the Browse activity. I have  
seen in

[1] that Browse can handle Java applets.

I've created an activity called "Java" that packs the Sun JRE. The  
activity
is downloadable from [2]. The JRE gets installed in the following  
folder:


/home/olpc/Activities/Java.activity/jre

Then I created a symbolic link to the Java plugin in the "plugin"  
folder of

the Browse activity:

[o...@xo-1e-5d-7a plugins]$ pwd
/home/olpc/Activities/Browse.activity/plugins
[o...@xo-1e-5d-7a plugins]$ ln -s
../../Java.activity/jre/plugin/i386/ns7/libjavaplugin_oji.so
libjavaplugin_oji.so
[o...@xo-1e-5d-7a plugins]$

I guess I have to do something else to make it work. Maybe something  
in the

"conf/mozpluggerrc" file?

That doesn't work. Running olpc-session as dsd mentions does overlay

Re: Using SoaS Blueberry to emulate OLPC F11 builds

Martin,

It looks like SOAS Strawberry will more closely relate to OLPC F11  
builds. Strawberry is based on F11 and Sugar 0.84.

Re: Using SoaS Blueberry to emulate OLPC F11 builds

[Reuben K. Caron]

Martin,

Blueberry is based on F12. The package differences will be much  
different.

Re: 1.5 - gnome-packagekit?

Neil,

Thanks for bringing this up. It looks like this could be of some value  
to deployments and something they could easily add should they choose  
to customize their build image. Keep up the good work and let us know  
how development is going.

Perhaps this is something for Zeroinstall  http://0install.net/ .
ZeroInstall allows for installation of software as a user so you can  
do

things without making system level changes.

I'm working on a setup for the XO that can give you a custom
environment. The entire thing goes into $HOME. I uses Zeroinstall to
grab everything as needed, even the window manager.  In practice the
bundle comes with the window manager but that is merely as a pre- 
filled

zeroinstall cache entry.

Because everything is done at the user level, it is very hard to break
things, but it still allows users to have a great deal of flexibility
with their system.

Yes, of course, you are correct. I was confusing this with the "single-

Absolutely, explaining the concept of joining Mesh Network # was  
complicated and confusing enough, it would be a shame to have to re- 
teach all of that.  Since you've corrected my pitfall, do you see any  
negatives to this?

Alternative to Create a new wireless network

[Reuben K. Caron]

Daniel,

Since we've run into problems with creating ad-hocs networks on the XO  
1.5 (1) (2), I've been thinking about this functionality, the change  
in UI behavior and perhaps the decrease in usability and I don't like  
it. I believe it is clunky to have children create their own  
networks..Who designates who creates the network? Why do I have to  
join that network? Why can't I make my own network and have them join  
me, etc.. All of this is aside from the technical limitations of which  
channel does my network get created on. Does the user specify channels  
1, 6, or 11 when creating the network, or does the channel randomly  
get set? If randomly set, how do we avoid channel overlaps and  
interference.

To ease all of this and maintain a similar UI, what if we:

-Create three faux "Mesh Channel #" icons in the Network view
-When the child wants to join a mesh network they will select one of  
the networks
-Upon selection: the XO will: 1. Scan to see if that ad-hoc network  
already exists and 2. if it does not exist the XO will create the  
network allowing other children to join it.

The one pitfall of this idea, and I'm not sure how much of an issue  
this would be, is also the pitfall of ad-hoc networks...when the  
initiator of the ad-hoc network leaves the network fails. When the  
network has a respective name it is a bit more obvious when that  
person has left and the reason why the network has failed, this would  
not be the case given the anonymity of a "Mesh Network #." A more long  
term solution to this problem may be for the XO to sense the loss of  
the initiator and recreate the network. In this case, the first XO to  
sense the loss of the network after some period of time would check if  
another XO has already setup the network, if not the XO would create  
the network or join the new one if it already exists.

Aside from the one pitfall, I think it would be really beneficial to  
maintain the same UI and appearance of functionality. Further  
development in this area may also help us get MPP back, at least at  
the software level.

Your thoughts?

Regards,
Reuben

1.5 - gnome-packagekit?

[Reuben K. Caron]

In the sugar environment we have the great resource of activities.sugarlabs.org 
  that children can browse through to add new activities. However, on  
the Gnome side of things we only have the yum terminal commands. While  
I realize children can add, remove, and install programs using such  
commands, it is a bit problematic when you don't know the name of what  
you are searching for or the actual name of the package you want to  
install or remove.

-Should we include gnome-packagekit to provide such functionality?
-Or would including it increase the complexities of managing  
deployments?

Since .XO and .XOL bundles were specifically designed to be "safe" for  
installation and removal, I'm concerned the inclusion of gnome- 
packagekit would allow one to more easily break their installation but  
I also think it would be nice for children to explore the rest of what  
Fedora has to provide.

Re: Wanted: List of Sugar activities for the XO-1.5

As I said it can be launched in Gnome through /home/olpc/Activities/ 
OOo4Kids.activity/resources/program/soffice. So I guess the question  
becomes is it sufficient to just link to this in the Gnome side and if  
so how can our build system incorporate this in the process?

I believe we are doing the same thing with etoys. How are we handling  
this with etoys?

Re: Wanted: List of Sugar activities for the XO-1.5

[Reuben K. Caron]

The only different one that comes to mind is WikiBrowse, a Wiki Slice.  
We have both an English and Spanish version. (*No French yet...*)  
However, as Martin said, aside from Activities where the localization  
work has not been done yet, OLPC does attempt to ship software that  
contains localized strings.

Hi,

[Added ericb to CC; Eric, we're talking about which applications to

How about suggestions for programs on the Gnome side?


That's a good idea, thanks.

I haven't decided what to do about OpenOffice yet -- at the moment we
don't ship it, but do ship abiword and gnumeric.  The options for it
look something like:

* just add the openoffice.org Fedora packages for GNOME.
 (How much disk space would that use?)


To provide the somewhat equivalent programs in full version OOo in  
comparison  to OOo4kids:


openoffice.org-writer
openoffice.org-calc
openoffice.org-draw
openoffice.org-impress

a yum install takes up ~300 MB, though I believe some of that is the  
actual download.




* just add the Ooo4Kids activity for Sugar.

* just add the Ooo4Kids activity for Sugar, *and* find a way to make
 the same activity launchable inside GNOME.  This would need Ooo4Kids
 to be useful for older kids as well, since they're the target
 audience for using GNOME instead of Sugar.

The OOo4Kids activity is here:

http://activities.sugarlabs.org/en-US/sugar/addon/4241  (100MB)


Claudia and I have been working with OOo4kids for the past few days  
and I really like it in both Sugar and Gnome and on my own Mac. (It  
can be launched in Gnome through /home/olpc/Activities/ 
OOo4Kids.activity/resources/program/soffice) It has very nice icon  
driven interface and has much of the functionality I would expect in  
typical office applications.


I like the idea of have a single application that is usuable in both  
environments to reduce the overall footprint. Could we have it linked  
into the Gnome Menu?


The one question I have is in regards to localization. Can we have one  
bundle that supports localization, i.e. changes default language  
according sugar/OFW values, or would we need different bundles?

Hi folks,

We'd like your help in coming up with a list of default-installed
Sugar activities for the XO-1.5 software release.  The current
activity list, which wasn't chosen with any particular criteria
or thoughtfulness, is:

Analyze
Browse
Calculate
Chat
Distance
Etoys
Implode
Infoslicer
IRC
Jukebox
Labyrinth
Log
Maze
Measure
Memorize
Moon
Paint
Physics
Pippy
Read
Record
Scratch
Speak
TamTam *
Terminal
Turtle Art
Typing Turtle
Words
Write

Any suggestions for activities to add?  A reasonable set of criteria
for looking at the suggestions seems like:

(a) works on 0.84 (and preferably 0.82)
(b) complete translations for OLPC deployment countries
(c) reasonably low disk space use
(d) download popularity on activities.sugarlabs.org

Thanks!

- Chris.

Martin,
Glad to hear you found the root cause. If we can come up with one or two

this and then enable squid; I'm sure they will be glad to do so.

Re: [Server-devel] Browse-101 for 0.82 and XS-0.6 interop

[Reuben K. Caron]

The G1G1 set of activities (1) on wiki.laptop.org was updated to include
Browse-102, I believe at the time the composite image was created for
8.2.1. This version does appear to work on 8.2.1 and has your auto-login
magic working with an updated XS 0.5.2.

Can we get a definitive answer on which to use 101 or 102?

Thanks,

Reuben

Re: [Server-devel] Filtering and authentication

[Reuben K. Caron]

All of the documentation is contained within their download. It appears
like a nice lightweight solution. It is basically a captive portal that
requires authentication before allowing access to the internet. It takes
a different approach then netreg using dynamically created iptables
generated after a user logs in. Whereas netreg uses dhcp to assign one
set of ip addresses to an authenticated group of users and one set of ip
addresses to an unauthenticated set of users. It appears in their
current implementation nocat would require an authentication every time 
a user connects to the system and netreg would require a single
authentication event and subsequently would read the mac address from
the dhcpd.conf file and grant an authenticated ip address.

Reuben

Re: [Server-devel] Filtering and authentication

[Reuben K. Caron]

Henry,

Thank you for your thoughts and examples. This is exactly why the XS
installer does not contain any content filtering software. It is very
much a cultural and deployment specific issue.

As Anna said, in their case and in the case of every public and many
private K-12 schools in the US they must implement a CIPA compliant
content "filter" in order to continue receiving important
telecommunications (e-rate) funding.

Again thank you for your thoughts and the litmus tests you provide.

Regards,
Reuben

Yes, I was particularly thinking of you and your experience in Ethiopia
and the difficulties you faced to re-secure the laptops. I prefer to
think of it as: Is there a realistic and common use case for when a
*deployment* would want or need to run enable-security.

[Server-devel] Upgrade to 0.5.1

[Reuben K. Caron]

There seems to be a differing set of instructions on how to upgrade:

from the wiki:
http://wiki.laptop.org/go/XS_Installing_Software#Upgrading_from_XS_0.4_or_earlier

"If you are upgrading from XS 0.4 or earlier, the process is similar to
a new installation, with some minor changes. In the menu shown right
after booting, you should choose the (preselected) 'Install with
kickstart' option, press the Tab key, and add 'upgradeany' to the boot
configuration line. After adding that line, press enter twice.
With this extra option, Anaconda will recognise the old installation and
will offer to upgrade."

the second from server-devel:

http://lists.laptop.org/pipermail/server-devel/2008-November/002493.html

"Just to make this clear, for the upgrade to work you need to select one
of the top two options, hit tab and then append "upgradeany". The
default selection has the ks.cfg file which prevent the upgrade choice
from appearing as an option in anaconda. (thinks it's the partitioning
info being present)"

Passing upgradeany to the kickstart option does not work. Passing
upgradeany to the top two options does work.

Two questions:

1. Which should be used.
2. If you pass upgradeany to one of the top two options that does not
use the kickstart, do you lose any functionalality?

Thanks,
Reuben

I've just pushed a patch to pilgrim's joyride branch to switch the
baseurl that gets written out in /etc/yum.repos.d/olpc-development.repo
from http://xs-dev.laptop.org/~cscott/repos/dist-olpc3-devel/ to
http://kojipkgs.fedoraproject.org/static-repos/dist-olpc4-build-current/i386/

(olpc3 is our 8.2/F9 repo, and olpc4 is the 9.1/F10 repo, so Joyride
should have been switched to write out the olpc4 baseurl when we
created the new repo.)

And, after the change, we don't have depsolving problems any more!
Here's the list of packages to be downloaded -- the next question is
going to be how to avoid many of these dependencies.  Perhaps instead
of trying the groupinstall, we should be hand-picking a smaller base
of GNOME packages from this list?



Well its the list up to the "Installing for dependencies" that is
explicitly requested, all the below is pulled in for deps. I'm not
sure how pilgrim builds the list but I think if it uses kickstart like
the other fedora build systems do you should be able to do a specific
"-packagename" and its removed from the list.

  
Does pilgrim (Puritan?) use "kickstart" like files? If so, how? If not, 
why do we not create builds using what seems to be fedora's standard 
build system?

Re: [Server-devel] Amateurish Workaround to Get Bonding to Work With eth1

[Reuben K. Caron]

Alright, so I am still seeing problems. 

yum --enablerepo=olpcxstesting install xs-config , did not work for me.

So I:

-wget 
http://xs-dev.laptop.org/xsrepos/testing/olpc/9/i386/xs-config-0.5.7.g11aaacf-1.noarch.rpm

-yum localinstall xs-config-0.5.7.g11aaacf-1.noarch.rpm --nogpgcheck

- reran domain config
-check hostname
-restart

log file still shows:

Dec 11 09:33:06 schoolserver kernel: bonding: lanbond0 is being created...
Dec 11 09:33:06 schoolserver kernel: ADDRCONF(NETDEV_UP): lanbond0: link
is not ready

until I issue the:

-ifenslave lanbond0 eth1

which results in:

Dec 11 09:52:47 schoolserver kernel: bonding: lanbond0: enslaving eth1
as an active interface with an up link.
Dec 11 09:52:47 schoolserver kernel: ADDRCONF(NETDEV_CHANGE): lanbond0:
link becomes ready

and then dhcp works.

Put this in /etc/rc.local

ifenslave lanbond0 eth1

Reboot.  And there we go:

Re: [Server-devel] XS 0.5 Second Attempt at eth1

[Reuben K. Caron]

Now that I have DHCPD running on a clean install. I can report that it
still does not hand out IPs. When I assign my laptop ethernet adapter as
172.18.96.1 and 172.18.0.1 I do get an ARP error from the server;
however, when I bump it up one address 172.18.0.2 it still does not ping.

Re: [Server-devel] XS 0.5 Second Attempt at eth1

[Reuben K. Caron]

After doing a clean install 4 times and dhcpd not starting I
investigated a bit more and I found:

When I

cd /etc/sysconfig/olpc-scripts
./domain_config xs5.org

It creates the xs_domain_name file in /etc/sysconfig/olpc-scripts/

However, /etc/sysconfig/dhcpd looks for this file in /etc/sysconfig/

When I copy /etc/sysconfig/olpc-scripts/xs_domain_name to
/etc/sysconfig/xs_domain_name; then start dhcpd it correctly generates
the config files and starts up.

For completeness I then deleted
/etc/sysconfig/olpc-scripts/xs_domain_name and
/etc/sysconfig/xs_domain_name.

Then ran: /etc/sysconfig/olpc-scripts/domain_config xs5.org ; this does
generate xs_domain_name in the correct /etc/sysconfig directory.

Re: [Server-devel] XS 0.5 Second Attempt at eth1

Yes, it is on the server. However isn't it a bit chicken and egg setting
an ip address that will be on the wire given that the device on the wire
is waiting for an ip address from the server?

Re: [Server-devel] XS - XO archiving and backup (was Re: [OLPC India] Issues on the ground )

[Reuben K. Caron]

XS 0.4 does include a backup and restore functionality. The restore is
through a web interface that can be accessed at
http://schoolserver/ds-restore. The one caveat to this functionality is
that it requires the XO to be running 8.2 (in order for the backup to run).

Re: [Server-devel] testing XS-RSYNC

[Reuben K. Caron]

Great, thanks. I was steered to the correct files and got it to work 
from both the USB and command line. The files I used can be found at:


http://dev.laptop.org/~reuben/xs-xobuilds/

Out of curiosity why do we require the tree files which come from:

http://pilgrim.laptop.org/~pilgrim/xo-1/streams/8.2/build767/devel_jffs2/

instead of the files which we document and publicize more frequently at:

http://download.laptop.org/xo-1/os/candidate/767/jffs2/
or
http://download.laptop.org/xo-1/os/official/711/jffs2/

FYI: updating build 766 to 767 WORKED using the command:

olpc-update --server schoolserver 
xo-1-olpc-stream-8.2-build-767-20081001_1616-devel_jffs2
