Re: [Server-devel] [XSCE] Can I name my server something other than http://BOX.LAN ?

[Tim Moody]

I think the question and answer don't quite line up.  What I name the
server and the alias I give for the browser to find it are not the same
thing.

The host name should be set with either in the admin console or via local
vars as the FAQ says, but the rest deals with aliases.

Are we now at the point of changing the default hostname to box?

Re: [Server-devel] [XSCE] xsce on rpi georgehunt's base-6.2

sorry, I may have seemed to imply that ansible needs to be 2.2. I think just

Is Ansible 2.2 the magical version? I have some notes on my unsuccessful 
attempts to install XSCE. So far, I have not succeeded at installing XSCE on a 
RPI2. (Do note though that imaging my SD card does work on the RPI2.) The 
various Ansible versions are mostly pulled from Github Except where noted.


All of these are RASPBIAN JESSIE LITE and George's Base-6.2 branch (except 
where noted).


  *   Ansible 1.8 Does not work. Roles use new keywords, ansible recognizes 
this and exits.

  *   Ansible 1.9 had a series of problems to what I later think is due to 
newer commands. Also, duplicate keys cause it to halt. (couldnt find duplicate 
keys, but that's what Ansible said). Wasn't taking such detailed notes at that 
time :\.
  *   Ansible 2.3.0 (Installed from Tim's Script.)
 *   fatal: Unable to mark file vars/local_vars.yml
 *   I think this is an attempt to untrack local_vars to permit changes.  
It will only cause a problem if you make changes and later try to git pull

using last duplicate key it sees. Previous versions error & stops.

[Tim Moody]

a project using donated hardware has several 250g disks rather than a single 1 
tb disk, so the use of raid (via bios) or lvm to create a single virtual disk

Hi,

A SIP server on the XSCE will allow for VOIP services (audio, video, text). 
There are numerous SIP clients on various platforms so it seems a good protocol

I have already included a SIP server in the upcoming deployment of XSCE and

You are not necessarily required to create accounts *per* user, but an account 
is needed. It is easy enough to create a default account (during initial 
installation/setup itself). The default login/captive portal page can have the 
details prefilled. For example, take a look at the video:

http://people.sugarlabs.org/anish/captive.webm

In this case, I just require the user to press the "accept and login" button 
and get redirected to school.lan from there (the last bit is not in the video).


You _can_ have named accounts if you want. You can have bandwidth control per 
account as well if needed (this would obsolete wondershaper). This can be 
useful if some users have fast access and others have limited bandwidth access 
to your server (can happen in a mesh setup).

So, in sum, it is easy to have the default redirect without requiring the user 
to enter credentials, but it is possible to have credentials as well.

I think the answer to br0 is yes.


Wonderful :-)

Subject: Re: Captive portal updates

Hi,

I wanted to ask whether a captive portal + radius server + radius server gui 
would be a useful feature and wanted to discuss possible implementation routes 
as this affects other services on the XSCE.

A radius server allows to have controlled access to server resources, internet 
connectivity, and allows one to create users, groups, and set aside network 
bandwidth. i.e. it is quite useful in a medium to large setup. A captive portal 
alongside it allows for good UX with notifications in phones, tablets and not 
having users to type http://school.lan.

The existing captive portal PR (#771) is a very good step in that direction, 
but I believe we will eventually need to use some kind of standard 
implementations - radius + captive portal setups.

Now that 6.1 is out of the door, I would like to propose a captive portal 
feature for 6.2.

In the current setup I am testing, I am using freeradius[1] as the radius 
server, and CoovaChilli [2] as the captive portal. Coova does it's own dhcp so 
it will have to replace dhcpd if it is used. Also, starting/stopping the coova 
services affects iptables, so initially, having it run in conjunction with 
dansguardian and squid might be a little tricky (though it is certainly 
possible, just needs more time to test/develop). Also, while freeradius is 
available as a rpm package, coova, and a dependency needs to be complied from 
source. I can create the packages for it though - it did not seem complicated.

So, the current approach I am proposing is:
1. If captive + radius is enabled, dhcpd is disabled, squid and dansguardian 
are disabled. Later, we can just have dhcpd disabled and the other two enabled 
if need be
2. If captive + radius is enabled, either we include a few knobs and levers to 
manage radius in our admin console (more difficult), or include a radius admin 
console (easier)

At the same time I have a question, since my understanding of xsce networking 
is limited. When setup in LANcontroller mode with both the internal wifi + LAN 
being controlled by XSCE, does all the LAN side traffic flow through br0? Is it 
always the case?  (in gateway mode too). If that is so, then I will configure 
coova to work on br0.

Now, this is progress since the user experience is exactly how you would see in

However, there are some notes:
1. Coovachili does its own dhcp, so probably we might have to use that, if the

2. By default it does dhcp on a different subnet. and _maybe_ because of that,

I should add to Tony's comments that Sugarizer will be a standard feature of 
XSCE as of the upcoming 6.1 release,  so the extent to which XSCE supports 
sugar will be dependent on the extent to which Activities are implemented in 
Sugarizer.  This is increasingly important as we encounter deployments where 
the clients are not XOs.

We need to experiment with http://www.squid-cache.org/Doc/config/cache_dir/

I think this is serious enough to warrant atleast a doc note to have the squid 
cache in a different partition as it makes the machine completely unusable 
otherwise. I don't think it is maybe the best idea to have it in library (but 
rather a separate partition). 

Or, as you say, a cron job - but in my case the bloat filled up the hdd in less

Yes, squid's model assumes that the cache that lives on a partition all by

itself with no real consideration for other programs on that partition.

Think that was the original reason for /library in the first place, maybe

we should rethink where the content/databases should reside.

Re: [Server-devel] [XSCE] Has anyone else seen squid swap.state bloat?

[Tim Moody]

I don't think it is practical to have a separate partition and while 
http://wiki.squid-cache.org/SquidFaq/ConfiguringSquid#What_.27.27cache_dir.27.27_size_should_I_use.3F
 talks about a separate partition, it and other docs make  it clear that the 
entire partition should not and need not  be used.
We need to experiment with http://www.squid-cache.org/Doc/config/cache_dir/ 
parameters to find something that works.  If that fails then we should create a 
cron job.

I think this is serious enough to warrant atleast a doc note to have the squid 
cache in a different partition as it makes the machine completely unusable 
otherwise. I don't think it is maybe the best idea to have it in library (but 
rather a separate partition). 

Or, as you say, a cron job - but in my case the bloat filled up the hdd in less 
than a week.

[Server-devel] rpi3 data points

[Tim Moody]

At the recent LinuxFest in Bellingham we had the opportunity to do a little 
capacity testing on the internal wifi of the rpi3. The LANForge system from 
Candela Technologies was used to create connections to the rpi3 and a maximum 
of 32 were made. We also did some throughput testing and saw 2.5 Mbs over all 
clients.
This was ad hoc testing in a noisy room full  of  booths, so not entirely 
rigorous, but a data point nonetheless. ___

Re: [Server-devel] [XSCE] Re: [UKids] Raspberri Pi/clone(s) most ruggedizable for OLPC fieldwork?

[Tim Moody]

Jerry could list the problems he's aware of.

But if you can get 64bit F24 running on Pine64, then you can use 
https://github.com/XSCE/xsce/wiki/XSCE-Installation#do-everything-from-scratch 
to install XSCE with ansible.  At that point you can tell us what works and 
what doesn't.

I ordered mine in Feb and am still waiting for delivery.

Jerry and George spent a lot of time migrating legacy XS code from F18 to F22.  
There is more work to get to F24.  I agree that we want to get there.

Looping back on this...

My PINE64 arrived in the mail today. Mine is the 2GB RAM variant, with gigabit 
ethernet, but no bluetooth or Wi-Fi (which is an add-in module)

 I actually have a couple of 200GB microSD cards that I just acquired, and I’ll 
be putting it through its paces. The SanDisk SDSDQUAN-200G-G4A retails for 
$249, but the actual street prices are $80 (on Amazon)

I suspect it will work fine in the PINE64. Does anyone here have any 
recommendations for putting XSCE through its paces, or otherwise stress-testing 
the install, besides normal benchmarking of static HTTP page load performance.

Release Notes for XSCE 6.0


What is it?


XSCE is the digital backbone for your education revolution. Put simply, School 
Server is an open-education project inspired by One Laptop Per Child to provide 
breakthrough digital learning tools to the world’s poorest children.


A Rose by any other Name


Internally and in the source code we refer to this software as XSCE, the 
Community Edition of the XS server originally from OLPC. Students and teachers 
often know it as Internet in a Box, a collection of educational materials and 
applications found on the internet, but available on the server even without an 
internet connection. We also refer to it as a School Server since it is aimed 
at schools and other places where people learn and performs the function of a 
server.


What's new in XSCE Release 6.0?


This release extends the tools available to educators in three ways:

*   It makes available free and open source content that is available in 
many languages
*   It provides new avenues for students to create, and share their work
*   It contains number of advances to permit easy configuration, tailoring 
of content, and monitoring of student work.


Newly Available Open Source Educational Content


*   KA Lite brings the online features of Khan Academy to the offline 
School Server based classroom. There are videos, exercises, tests, and student 
tracking in a number of languages, all selectable via a Graphical User 
Interface.  
https://learningequality.org/ka-lite/
*   Searchable offline access to Wikipedia and other content such as 
Wiktionaries and TED Talks in a variety of subjects and many languages, 
provided by the Kiwix server technology.   
http://www.kiwix.org/wiki/Main_Page
*   RACHEL (a curated selection of offline materials)  
 http://worldpossible.org/rachel/
*   Bring your own content by inserting a USB thumbdrive with content into 
the server having it immediately viewable by students.


Encourage Students to Write, Foster the Creative Process


*   Elgg provides the tools for generating social networks  
 
http://learn.elgg.org/en/2.0/intro/features.html
*   ownCloud provides client based tools for storing and retrieving 
materials stored on the XSCE local cloud.
*   DokuWiki (EXPERIMENTAL) provides a means for students to publish their 
work.   https://www.dokuwiki.org/features
*   Wordpress (EXPERIMENTAL -- enable in "local_vars") gives students 
experience editing/sharing using a tool that is becoming an industry standard.


New Tools for Administering the XSCE School Server


*   A new Graphical User Interface (Admin Console) to enable services, 
select and download content, get information
*   AWstats is a flexible tool for summarizing the web traffic on and 
through the server in graphical and detailed ways.  
http://www.awstats.org/


How do I get it?


There are three main methods of installing this software:

*   Use ansible and the git repository - this is the fall back when you 
need to customize or you have a platform for which we have not created an image.
*   Use an image you download - for some commonly used platforms we create 
image files that you can download, put on a usb stick or sd card and boot in 
your new hardware.
*   Create and use your own image - this will appeal to you if you want an 
image to use in multiple machines and are able to use the tools we provide to 
create it.

In each case you need hardware that has been assembled, but with nothing 
installed on it.

Detailed instructions on each of these methods is at  
 
https://github.com/XSCE/xsce/wiki/XSCE-Installation.

[Server-devel] rpi - 2 questions

[Tim Moody]

The xsce rpi2 images are pretty much there based on
https://www.kraxel.org/repos/rpi2/ But there are two decisions still
outstanding.

 

1) fsck on rootfs

 

Kraxel had in /etc/fstab

 

UUID=1a57e552-0bae-4a16-9705-12d51e12db05 / ext4 noatime 0 0

 

but I have noticed error messages about lost inodes when I mount this
partition on another machine and was thinking of changing to

 

UUID=1a57e552-0bae-4a16-9705-12d51e12db05 / ext4 noatime 1 1 

 

which would force fsck on each boot, but add a delay.  an alternative would
be to document the use of touch /forcefsck to force it only on the next
boot.

 

Is changing fstab a good idea and is there a better one?  My inclination is
to make the change rather than rely on someone to force fsck.

 

2) kernel

 

Kraxel had 4.4.1, now upgradable to 4.4.6

 

https://github.com/raspberrypi/firmware

 

has 4.1.20 and seems a bit more official, but there is no repo I can find,
so no dnf update.

 

My inclination is to stick with Kraxel, but I am open to suggestions.

 

Another factor is that rpi3 will need the device tree from
raspberrypi/firmware and possibly other files, but this is not very relevant
until they get a 64bit kernel and linux.

At lot of this content would be quite large in static html, so kiwix.org have 
compressed it into a file format called zim which is then rendered by their 
kiwix server which is either proxied by apache or accessed directly.  Apache

If you already have an (apache) webserver running, is there an option to serve

Hi Bishnu,

 

Actually if you use xsce, there is a graphical user interface that will allow 
you to select by language all of the wiki type content from the url Adam 
mentions and download and unzip it to a location where the kiwix server can 
render it. In your case, since you have your own server, you could use xsce as 
a staging machine to make life easier.

 

For OSM, Anish has freshly generated India and Nepal and can give you a link.

 

Tim

Re: [Server-devel] [XSCE] Re: XSCE testing on NUC/el7 ; munin not working

Re: [Server-devel] zims

you're right.  I mistakenly thought it referred to the source, which came
from the zip file, but in fact the target directory is not created unless
you enable kiwix.  I just tested pre-creating the target directory and I
think that fixes the problem.

I will have to retry this. I do not remember as I have done 4 installs and
tried several kwix installs.
I do know that rachel on a centos 7.1 install failed with a crc error due to
mp4 files. It would not install.

But I have another install where it works perfectly?

Note that my upstream cat5 connection uses the network socket on the NUC [1]
so the setup may not be the same as mentioned in the instructions.

Will try to do this again in f22 xsce -live and make notes.

Thanks for all your work on this amazing software;

[Server-devel] XSCE Network Testing

[Tim Moody]

Network discovery and configuration have become increasingly complex as we
try to handle more and more cases.  I have created a test plan for
networking to supplement the general test plan for XSCE.  There are probably
additional cases that should be tested, especially in the area of
connections that are added or changed after installation, so add them if you
can.

 

Please help get this right by testing and recording your results in

 

https://docs.google.com/spreadsheets/d/1NTePIfkhBJpRbBQ867V3WK_ORgunMMfaZt9V
Vd8tCmI/edit?usp=sharing

 

Please copy the template to a new worksheet and fill in the testing
environment and the results for scenarios tested.

 

The overall test plan for XSCE is at

Re: [Server-devel] [XSCE] khan_assessments.zip download fails

[Tim Moody]

the easiest workaround is to have enough memory.  I bumped the vm up to 1.5G 
RAM and the problem disappeared, but this could come up if you put a large 
storage on a machine with small memory and want to run kalite with the 
assessments.

Yes

Great. I was actually thinking whether we should have different rows for all 
such info, or just a link to /etc/xsce.ini. Maybe it makes sense to have them 
in separate rows just in case the info in /etc/xsce,ini may be stale?

 

some things like ram and storage are not in the ini, but I debated about 
repeating things that are.  the question could also be asked about the commit 
hash, which is in the ini.  I guess it's a tradeoff between being able to see 
the context at a glance and having to copy things.

 

what do L0 and L1 mean?

 

 

This is a remnant of my semiconductor h/w verification days. Wanted to have a 
basic distinction between depth of testing. So in this case, L0 would mean 
basic testing of the most critical stuff. L1 means deeper level testing. The 
idea being an L0 test run would be over much quicker and L1 take additional 
time (and maybe expertise) so not everybody might want to do it. 

Thoughts?

I think the whole question of test methodology has not yet been addressed, but

Re: [Server-devel] [XSCE] [RFC] XSCE 6.0 test matrix

[Tim Moody]

good start.  I would break out NUC and VM by OS (centos vs f22)

 

also, probably need short explanations on some of the header fields

 

https://github.com/XSCE/xsce-tests, most recently owned by George, should get 
into the picture

 

https://github.com/XSCE/xsce/blob/master/docs/TESTING.rst is getting stale.

Subject: [XSCE] [RFC] XSCE 6.0 test matrix

 

With the XSCE 6.0 release imminent in a few weeks, it would be great if we 
could get the code tested in the many platforms we support. To this end, I have 
started working on a test-grid. The spreadsheet is linked here:

https://docs.google.com/spreadsheets/d/1pevXOSIoV9LQF_8QV-5_ds0WPqC1Lko3UYYJh8UnUkM/edit#gid=0

At this point, I'm looking for contributions to improve the structure of the 
sheet, but more importantly, for respective module maintainers to fill in the 
necessary testing steps in the 'Template' tab. 

Note: This is NOT a call to fill in test data yet. The sheet is not ready - 
both in completeness and user-friendliness. Please help with making it so. 

Thank you all!

Re: [Server-devel] [XSCE] CentOS install - i3 NUC - Code to Inspire

[Tim Moody]

Actually now I see more.  They were so slow loading I thought the higher levels 
didn't exist.

 

Still not getting anything above 10 or 11 depending on how you count.  At some 
of the lower levels there are tiles missing.

Nick, et. al. 

Would love some feedback on the tiles. 
http://home.braddock.com:28112/osm/slippymap.html

The scheme I've broadly followed is this:

Zoom <= 6

Natural earth data overlaid with text labels

Zoom between 7 and 10

OSMBright as a base layer + hillshade + slopeshade + color-relief. DEM data is 
SRTM 15 arc-sec resolution.

Zoom >= 11

OSMBright + hillshade + contours. DEM data is 1 arc-sec resolution

Would LOVE feedback, critiques on the design styling and suggestions to improve 
it. For example:

1. Contours at zoom level 11 is maybe a bit overdone, can be included from zoom 
12 or 13 onwards. 

2. Between zoom 7 and 10, the tiles look faded. This is primarily due to the 
hillshade, which is gray in color. Now if this is really a problem, I could 
make this situation slightly better.

3. Zoom level 10 (the last level with the crazy colors) has too much faded out 
elevation, and in the next level the elevation features are much sharper. Is 
this a problem?

4. The colors of the contours is blue. Maybe there is a better color out there? 
I suck at design and colors generally!

In terms of size, the tiles with elevation data are roughly double the size 
without elevation data.

 

Thanks everyone for being a great help during this process. :-)

When a usb drive is inserted into the server it is mounted (hopefully).  If
the server is restarted that mount disappears even if the device is still
attached.

 

I started down the road of remounting any drives that were automounted for
shared content.

 

Now I am wondering if at startup I should mount anything returned by blkid
that is not already mounted.  (I don't want to alter fstab.)

 

Also, what are the chances that a device that was /dev/sdb1 for example will
still be so on restart?

Re: [Server-devel] [XSCE] automount

I had it on good advice that mounts are not reestablished on restart.  It
makes sense as there is no physical event of plugging in the device.

But because of your comment I just rebooted and the mount was in fact
reestablished, so looks like it is not in fact a problem.

It would be great if you could do a docker proof of concept on xsce.  Most of 
us have little experience with it beyond what we read.  I don't really see 
docker and ansible as alternatives, since an ansible playbook can easily run in 
a docker container.  I'd like to move from VBox to docker at some point.

[Server-devel] usbmount

[Tim Moody]

I'm working on adding LibraryBox/PirateBox type functionality whereby if a
usb in plugged into the server it is automounted by usbmount and if it has
/share, /Share, or /PirateShare in its root directory a symlink will be
created in /library/content/USBx depending on where it was mounted.

 

I think this should be enabled by default.

Subject: Re: [XSCE] usbmount

 

Why the need to have a folder with a specific name? In different langs, the 
folder name could be different to make sense to users?

I assume you mean on the usb not the symlink.  The worry was that we wouldn't 
want to share the /grades or /myphotos folders, so we should restrict the share 
to specific folders.  The link students will see will just be USBx, which is 
pretty international.  Also, /library/content renders unicode names, so files 
inside the share in any language should work.

Remember, this is a dynamic share, not a copy at the moment.

Another idea could be to link it to the folderspace where owncloud houses it's 
content to allow easy back and forth between the server and the USB key - 
unless there is a better mechanism. 

 

I think owncloud is a much more feature-rich alternative.  You can create 
folders with any name you like with restrictions on users.  You can upload 
files to those folders from your hard disk or an attached usb.  I also think 
owncloud creates db records for uploads and we would have to do that manually, 
which could be tricky and risky.

 

I think the automount is simple with some restrictions and owncloud is more 
complex with more functionality.

Yes, I meant on the USB. So if I understand your explanation correctly, 
everything in the USB drive will be linked/shared in a folder visible to the

 Everything under /media/usbn/share (or either of the other 2 checked ) will

[Tim Moody]

found docs, but 

 

on my fedora 22 nuc usb does not automount even though found and usbmount is 
enabled and configured for vfat file system

 

when I remove, even after umount I get unable to read boot sector to mark fs as

I have tried two drives and both exhibit the same behavior even though both 
mount on win7 and automount on f20 (albeit with a complaint about the dirty bit)

# WARNING!  #

#   #

# The "sync" option may not be a good choice to use with flash drives, as   #

# If you omit it, don't forget to use the command "sync" to synchronize the #

# data on your disk before removing the drive or you may experience data#

# loss. #

#   #

# It is highly recommended that you use the pumount command (as a regular   #

# user) before unplugging the device. It makes calling the "sync" command   #

# and mounting with the sync option unnecessary---this is similar to other  #

# operating system's "safely disconnect the device" option. #

Subject: KaLite splitting collections into smaller bits

 

Hi, 

I am creating an offline copy of the kalite content and it would be useful to 
know the sub-collections in particular subjects whch would be desireable. 

For example in ES, I am making the full dump of all Maths videos, but I assume 
it would also be useful to have Maths-elementary Maths-senior etc. 

So feedback for what goes in which collection would be useful!

Here is the reference list in Maths-ES.  Similar lists exist for Maths-EN, 
Sciences and other topics. 

I think it only make sense to split a collection if the size is over 10G or so. 
Whatsay?

You can get an idea of the same by looking at the kalite section here:

This looks great and not overly complex.  XSCE uses one convention that you are

probably /library/osm or tilestache or some combination.  Can tilestache.cfg

Happy to help with the testing. I have an intel NUC running an atom processor 2

Could you tell me how to get the mbtiles from your ftp. If this works, I can

Hi all

 

This is about the project to bring a new way of storing OpenStreetMaps offline 
for internet in a box (schoolserver).

 

(Apologies if I'm using the wrong mailing list, feel free to add more)

 

I wanted to test what it would look like to run Tilestache to serve .mbtiles 
using the schoolserver. So I installed XSCE on a local VM with Fedora 21 here, 
installed Tilestache, moved the .mbtiles in it, and did some testing.

So far I only tested with Nepal zoom 0-13 and Nepal zoom 14-15 (to see how 
combining multiple files was working)

I reduced the VM to use only 1 core at 50% (I'm on MBP Intel i5 2.6Ghz, 2 
cores). Speed was decent when viewing with leaflet in my browser from my laptop.

 

I've created a gist that explains all the steps required to do it

https://gist.github.com/jeromegv/cb64bc2c994e80af

 

The reason I wanted to test it was also to see if the integration would be 
relatively straightforward. I assume you would eventually want to do the 
install through the schoolserver admin console. When comes the time to do that, 
I might not be the person to do this integration, but I think that the steps 
I've done so far should at least prove that the XSCE stack should be 
compatible. 

 

*   I might not have the best testing setup or what is similar to a typical 
schoolserver, if you have the proper hardware to test, let me know, I can send 
you the .mbtiles on a FTP for nepal and you can test it (about 1Gb)
*   Feel free to provide feedback on the GIST and if the integration seems 
to make sense
*   There's an extra optimization that is possible for tilestache, to cache 
the tiles to the HD once they were retrieved and served from the .mbtiles once. 
It's currently disabled. Not so sure if it's worth it and how much we would 
gain considering MBtiles are already pre-rendered files, perhaps better to test 
once we have a full planet. The downside is that it stores on HD a lot of PNG 
files and this might eventually baloon if you get tons of people to use those 
maps. Benefit of sticking entirely to mbtiles is we know exactly how much disk 
space. Might be optional setting from admin console when there's plenty of HD 
available.
*   Next step for me will be to test generation of MBtiles for bigger 
country and eventually get to the Planet. Will need some type of cloud setup to 
manage/store all that.

Thanks

Re: [Server-devel] [UKids] Re: [XSCE] Tilestache on XSCE stack (OSM offline)

[Tim Moody]

I think rendering on the fly is a bit of a misnomer as the metatiles are just 
concatenated pngs to save on the number of files in the file system, but they 
aren't compressed and are just rendered tiles.

 

http://wiki.openstreetmap.org/wiki/Meta_tiles.  I think Braddock used 4096 
tiles per metatile.

I see i see, so the disk space can't be exactly compared to what we see in 
.mbtiles, since if you had to transfer that to another server and did not want 
to do rendering on fly, this would be a different file size (much bigger).

As is obvious, for zoom levels 0-11 I had generated tiles for the entire world,

data source I used was the nepal osm data

Zoom level 12 and onwards, tiles were generated only for nepal.

The bigger question i'd be asking is the setup required to generate tiles, and 
what it would take to do for the entire planet. I guess Braddock would be happy 
to give access to Jerome on hadron if he wants to give it a try. It is a

Re: [Server-devel] [XSCE] Changing the XSCE's hostname (or the address one enters in the browser)

[Tim Moody]

xsce distinguishes between hostname (schoolserver) and domain name (defaults to 
.lan).  You can change the second of these no problem in the console.  You can 
override the first in local_vars, but if you do XOs won't automatically find 
the schoolserver.  (I have a machine that I named xsce.lan, which works fine.) 
The expectation is that if you need multiple schoolservers or need to add to an 
existing network that you will do it by changing the domain name, so only that 
is exposed in the console.

Hi,

What would be a method to change the XSCE's hostname post an initial install 
from schoolserver.lan to something else. 

The web-admin console does not allow changing this, so I am guessing it will 
break a few things if I force the issue. What would be a way around this..

1) Either change the hostname
 

OR

2) Redirect to schoolserver.lan upon entering my-preferred-addr in the 
browser.


1) would be preferred and 2) a backup.

Thoughts on how to best do this?

   G'day Tim,
  
   Thanks, that's interesting.
  
   My best guess is you have a bad connector and the 24-hour thermal
   test you did fixed it.  The problem may return.
  
   Another guess is that the card has the production state awareness
   feature [1], part of e.MMC v5.0, which uses the storage cells
   differently before
  they
   are enabled for normal use.  The state can be changed with suitable
   tools,
  or
   will clear itself once enough data is written; followed by a power
   cycle.
  The
   result is a sudden increase in performance after that power cycle.
  
  interesting ideas.  I have no way of judging either.
 
  My guess is that I tried so many different ways of partitioning it
  from fdisk to parted that it was so messed up that an xo 1.5, a nuc,
  and a dell all found it corrupt, compounded by the fact that systemd
  has it in use even if it is not actually mounted.
 
  The sdcard holder is also looking pretty suspect as used with the card
  slot on the xo.  I put the micro sd in the holder back into the xo 1.5
  and it reported two devices with pttype of dos, but gave unknown
  file system when I tried to mount

Re: [Server-devel] [XSCE] sdcard for /opt and /library on xo 1.5

[Tim Moody]

I think the bottom line is that on this xo1.5 I need to use a usb thumb
drive instead of this micro sdcard and its holder.

 Subject: Re: [XSCE] sdcard for /opt and /library on xo 1.5
 
 G'day Tim,
 
 Thanks, that's interesting.
 
 My best guess is you have a bad connector and the 24-hour thermal test you
 did fixed it.  The problem may return.
 
 Another guess is that the card has the production state awareness feature
 [1], part of e.MMC v5.0, which uses the storage cells differently before
they
 are enabled for normal use.  The state can be changed with suitable tools,
or
 will clear itself once enough data is written; followed by a power cycle.
The
 result is a sudden increase in performance after that power cycle.
 
interesting ideas.  I have no way of judging either.

My guess is that I tried so many different ways of partitioning it from
fdisk to parted that it was so messed up that an xo 1.5, a nuc, and a dell
all found it corrupt, compounded by the fact that systemd has it in use even
if it is not actually mounted.

The sdcard holder is also looking pretty suspect as used with the card slot
on the xo.  I put the micro sd in the holder back into the xo 1.5 and it
reported two devices with pttype of dos, but gave unknown file system when
I tried to mount

[Server-devel] sdcard for /opt and /library on xo 1.5

[Tim Moody]

I have been around the block with a 128G micro sdcard allegedly from
Sandisk.  I made various attempts at creating two partitions and formatting
them ext4, some of which progressed at the rate of 10G/hour.

 

I finally used dd to write /dev/zero to the entire device, which took almost
24 hours.

 

After that parted mklabel msdos and mkpart worked fine and mkfs.ext4 also
worked fine in a couple of minutes.

[Tim Moody]

I agree on the VM.  I use VBox and usually give it 1G.  I have started giving 
100G of disk because it only takes what it needs.

 

I haven't gotten into vagrant, so I just create a 'Base' VM and then clone it, 
which takes about 2 minutes.  I put minimal fedora (I have both 21 and 22) plus 
my keys, git, nano, wget, ansible, and mkdir /opt/schoolserver into the base.

 

Now I just have to clone the vm, clone the xsce repo and either 
./install-console or ./runansible.  I usually save this VM too, for future 
cloning to do tests.

I guess a VM using a single core and 512 MB or 1GB RAM would be a reasonable 
starting point. A Rpi-2 would be great as well. You could just test from the 
latest master branch, and it *should* work. Currently, a role called 'Pathagar' 
is broken, so you may have to disable installing it in vars/default_vars.yml 
when you give it a go. 

Is using a VM, I often tend to use vagrant. You can use a fedora 21/22 minimal 
or centos minimal image. 

This is the image I used for testing my XSCE install, where things went 
smoothly - 
https://github.com/holms/vagrant-centos7-box/releases/download/7.1.1503.001/CentOS-7.1.1503-x86_64-netboot.box

If using centOS you will need to enable the epel repo - yum install epel-release

 

Hope this helps. 

Best,

Anish

Got this idea from this post where :

Should I be testing with XSCE 5.1? XSCE 5.5 beta? Should I get some hardware

A few questions.

 

Which of the filtered datasets did you use for populated places? 

 

Are they from 
http://wiki.openstreetmap.org/wiki/Planet.osm#Country_and_area_extracts ?

 

Is the directory structure such that separately rendered tiles for different

I did some sampling.

 

In Manhattan the maximum zoom is  http://xsce/iiab/maps/tile/15/9649/12318.png

In Northern Ontario the maximum zoom is

In the middle of the North Pacific http://xsce/iiab/maps/tile/14/1088/6190.png 
a surprising level 14

 

Moving slightly left I get http://xsce/iiab/maps/tile/14/1080/6191.png so I'm 
not quite clear on the generic blue tile point.

 

I'm also not clear on the point about the meta tiles.  From what I read in 
http://wiki.openstreetmap.org/wiki/Meta_tiles , meta files just concatenate the 
smaller tiles, so I'm not clear on how that saves space.  I do understand that 
it greatly reduces the number of nodes in the file system making retrieving 
them viable.

 

I looked at space usage by zoom level on the current IIAB OSM:

In IIAB we use a dataset of populated places to render at the highest 
resolution level, and render the rest of the world at a slightly lower 
resolution.  Our highest resolution is high enough to see individual buildings. 
 Our total dataset of rendered tiles for the world with detailed populated 
places coverage is 100GB.

 

Another optimization we made for IIAB that contributed considerable dataset 
size reduction and helped with filesystem efficiency - we use the OSM meta 
tiles, which normally store 64 tile png images, but we modify them to store 
4096 png images per file, and we made an optimization so that identical tiles 
are removed (think of all the blue of the ocean cover 75% of the earth).

 

We use Leaflet as our javascript web front end, and it works quite well.

Re: [Server-devel] [XSCE] RE: [UKids] Re: [support-gang] Taking OpenStreetMap Offline - DESIGN Call - Thur June 11, 10AM EDT / 2PM UTC

[Tim Moody]

couple of observations:

 

As expected, the new tiles have a lot more detail.

 

There are more levels of zoom in the new ones.

 

Some names have changed - the old map had Lalitpur and the new one has Patan 
(both are used)

 

I don't see any boxes for unprintable characters, but there is a lot less 
Devanagari. (Google maps has more)

 

Is it possible to merge individually generated regional tiles?  for example if 
you rendered India and Nepal separately would you get both?

 

What happens if you render the world at level 10 and then specific countries at 
16?

- DESIGN Call - Thur June 11, 10AM EDT / 2PM UTC

 

Hi,

Following from the skype call this week, I uploaded Nepal's OSM data in 
postgres and render tiles to see performance, and as expected, everything is 
blazing fast. 

The pbf file went into the postgress in less than 5 minutes, and tiles are 
being rendered pretty fast as well.

You can check it yourself by going to 
http://home.braddock.com:28112/osm/slippymap.html

* Select Mapnik

* Zoom out and center over Nepal

* Select Local tiles

* Zoom in

I don't know what this proves as the bottleneck still is doing this for the 
entire planet, which we need to figure out a way for anyway.

Best,

Anish

Great document. I've added 2 comments to the document, feel free to incorporate 
into the document if that makes sense.

 

Also added a TODO for myself to do more research about the various search 
solutions. 

I've used Nominatim in the past (on the client side, not the server 
infrastructure) and it was overall very good, but I'll want to know more about 
the other ones.

Re: [Server-devel] Trying to access a school server from the outside world

[Tim Moody]

xsce listens on ssh, so if you expose that port externally you can access the 
server.  probably you don't do this as we usually put the server behind a 
firewall.

George Hunt set up an OpenVPN hub which some installs can use.  Servers connect 
to the vpn hub and connected users can then pass through the hub to the server. 
 Both users and servers need keys stored on the vpn hub.

You would need to check with Adam and George.

Re: [Server-devel] White list on xsce

[Tim Moody]

The whitelist can be edited in the Admin Console at http://schoolserver/admin.  
You need the xsce-admin user's password to login.  Go to the Configure menu 
option and it should be straightforward.

You can also turn Squid whitelist filtering on and off.

Not sure what version you have, so these features might not be there.

Hi Jerry,

Thanks for the response. So you're saying that I *should* be using the latest 
master and it *should* work with those tweaks that you mention? :-) 

I don't require any authentication for the wifi network, and xsce out of the 
box as the ssid is okay with me. Will check upon the hostapd conf to see if the 
interface is br0.

Also, did you face issues with dhcpd not coming up complaining about no subnet 
declaration in your testing? Seems to be happening here, although I'll let the 
current runansible run finish and then report back. 

Oh, and slightly offtopic .. moodle probably needs postgres which is disabled 
by default :)

Cheers,

 Hi,

 Have been struggling all day trying to figure out how to install current
 master on a NUC.

 I set one up two weeks ago in the following fashion:
 f21-server install on a NUC
 xsce install in appliance mode
 install hostapd and configure wifi chip to be used
 rerun xsce playbooks

 This seemed to work well on the first try and is being used at the school
 in the mountains I went to.


Yea, we made some great progress in the WiFi realm.

 Now I have two more NUCs and am trying to setup current master

 I installed hostapd before running any playbooks, and running xsce seems
 to
 enable a bridge network br0 and use it as LAN. I also see a hostapd
 config
 option in the vars file.


Yes we added basic WiFi AP mode support, sets up an open AP with no
authentication using bridging. The only thing configurable in local_vars at
this point is the ssid, we didn't extend the all the variables from
hostapd.conf to local_vars yet. A pull request to do so would be welcome.

 Would like to know the 'proper' way to go about it. i feel like I am
 trying
 various permutations and not setting things up as they should be. Any
 pointers would be useful.


If you're running authentication, I'd let ansible finish then overwrite the
hostapd.conf file with your version but be sure to add bridge=br0 to the
file then restart the hostapd service.

Jerry

[Tim Moody]

At this time, and subject to testing, xsce can be installed on Fedora 18 (for 
XOs), 20, and 21 and on Centos.  Any and all of these needs testing.

 

Keep in mind that xsce is not necessarily bundled with one of these OS in that 
you can install the os and then runansible or one of the other setup scripts.

 

However, to make life easier, George has images and an installer that you just 
stuff onto a machine and have a working xsce.  Similarly Jerry has an iso that 
already has all the needed rpms and other installables and will give a livecd 
style ready to go xsce.

 

However, you also need to keep in mind that if you install from an image or an 
iso you are getting a particular os and a snapshot of xsce.

 

If you want to roll your own, you can first install an OS.

 

I use what's on XO-4 for F18, minimal for F20, and as Danishka mentions Server 
Edition for 21.  I haven't tried Centos.

 

Finally, please also keep in mind that all of these things have happened since 
the last release (5.1) of xsce so are a work in progress, which is exactly why 
a lot of testing is needed.

 

 

 




I would like to help on both CentOS and Fedora side.

Please remember that Fedora also introduced Server Edition since Fedora 21. [1]

Re: [Server-devel] [XSCE] Re: XS(CE) integration with other environments?

[Tim Moody]

XSCE tries to play in three distinct roles:

1) Gateway - the traditional XS configuration with an upstream connection, 
usually dhcp, and a downstream connection with dhcpd and dns on a fixed address 
with the name schoolserver.
2) Appliance – only an upstream connection, usually using dhcp, but in the 
future with a fixed ip address.
3) Lan Controller – only a downstream connection, provides the same services 
and ip address as a Gateway but with no routing.

XSCE uses a combination of flags indicating the installer’s intent and 
discovery of the adapters and gateway present to select one of the three roles 
above.

The other convenience for more complex topologies is that subdomain names are 
possible, so that each downstream can still look like ‘schoolserver’ to its 
clients, but look distinct to those upstream.

Subject: [XSCE] Re: XS(CE) integration with other environments?

You are taking my remarks a bit out of context, although it is hard for me to 
tiptoe around explaining things while trying not to insult anyone.


From the schoolserver perspective, schoolservers as originally implemented 
were meant to be an all-in-one system.  They provide DHCP for the laptops, act 
as the Internet gateway, provide anti-theft  backup services, etc.


Sugar  XOs have hardcoded logic expecting the schoolserver to be called 
schoolserver.  Schoolservers are also expected to have certain hardcoded IP 
addresses in case an XO runs into anti-theft problems, etc.


But in larger networks/school districts, I have seen schoolservers installed 
into networks where they are not allowed to control DHCP.  They often were not 
the Internet gateway, and local policies might not allow them to be called 
schoolserver.  Occasionally the schoolserver isn't even in the same building 
as the XOs, and may be on a completely different subnet.


This is a whole concept I once called Sugar for the Enterprise {school 
district} but I don't know if that is worth pursuing at this time.



XSCE is interesting in that it supports things like Internet-in-a-box which 
are not XO specific.  And from what I've seen, the XSCE community may in some 
ways be more active than the Sugar community.


But it is unclear to me what features the XSCE community is implementing to 
support deployments other than those they are directly involved with, or what 
the feedback loop is there.

Can someone further explain Sam Greenfeld's suggestion below from 
http://lists.sugarlabs.org/archive/iaep/2015-March/017279.html ?  No 
obligation, but if there are common requests missing from XSCE  similar, 
let's understand them:


The XO/Sugar/Schoolserver combination was originally promoted as a complete 
solution which could be used independently without anything else.

But in practice, there is a need to integrate with other solutions.  Sugar may 
be a great educational environment but there is a need to tie it into existing 
schools and curriculums.  OLPC had educators on staff looking into this 
problem, but I don't think we have that luxury.

As an example, the same kludge hacks kept being made over and over to 
integrate Sugar  XOs into environments where the schoolserver might not 
control the network, proxy authentication/802.1x networks were used, etc.  For 
some reason this functionality never made it upstream.

  I wonder what the top usable speed for an sd card is for this device.

For such 128GB microSD's, we're now down from $29-shipped-from-China to 
$17-shipped-from-USA.  However new condition with Brand New retail 
packaging raises question as to whether this might possibly have been used a 
priori?  eBay seller is rated 98.7% so worth the risk?  Limit of 2 per 
customer, but how many earring do we need ;)

[Server-devel] external batteries

[Tim Moody]

I didn’t find the batteries I saw before, but this looks pretty good.

http://www.amazon.com/AmazonBasics-Portable-External-Battery-Charger/dp/B00LRK8JDC/ref=sr_1_22?s=wirelesssrs=10112675011ie=UTF8qid=1425048233sr=1-22
weighs 8 oz.  check my math, but at 10K mAh that should power a 3W 5V device 
for 16.67 hours in a perfect world. this one has two usb outs, so for devices 
with portable hdd there is a supply for the device and another for the hdd.
some of these take awhile to charge, so two smaller ones might be better, 
though more complicated.  not sure if you can charge and use at the same time, 
but input is separate from output.___

I'm excited about our discussion yesterday. Based on your research, what do you 
think of: 

http://www.amazon.com/gp/product/B00F4U49M6/


From the comments, I suspect that there is really a 3.7v battery inside, so 
that there is enough headroom to actually charge the thing.  Then they must do 
a dc-dc conversion back up to 5v output

I think our application will be gentle on the electronics, compared to mainline 
usage.

I like the idea of lcd capacity indication.  The comments suggest that output 
reading is not reliable, but hopefully it will be repeatable.___

Re: [Server-devel] [support-gang] [XSCE] Re: school server weekly mtg minutes

The part I don't fully understand is that android (using chrome in my case) 
can find http://schoolserver.lan, just not http://schoolserver.  Looks to me 
like the phone reaches the xsce dns server, but the server only resolves 
schoolserver.lan.

So in the settings sections I see a number of options

Web (which I guess would be html)
Database (SQL, Mongo)
Files
REST - not quite sure what this would do

Also there is this
https://github.com/opensearchserver/oss-text-extractor
(didn't check if it came bundled with the rpm - there's a separate rpm
from a different source as well). From the documentation

- 

An open source RESTFul Web Service for text extraction and analysis.
oss-text-extractor supports various binary formats.

   Word processor (doc, docx, odt, rtf)
   Spreadsheet (xls, xlsx, ods)
   Presentation (ppt, pptx, odp)
   Publishing (pdf, pub)
   Web (rss, html/xhtml)
   Medias (audio, images)
   Others (vsd, text, markdown)

- 

Seems quite useful.

Also, I think the usefulness of a search engine would go up when there
is more student/teacher generated content.

Cheers,
Anish

Re: [Server-devel] [XSCE] copyright and licensing

[Tim Moody]

My original question had nothing to do with forking IIAB or using its code, but 
rather sought it as a model for including licensing in the code I write so as 
to make it usable by others.  In addition to choosing different licenses, the 
IIAB strategy is to include a license only at the top level of the tree, 
whereas OLPC had a license at the top of each module.

Having said all that, I think IIAB has modules that could be of interest to 
developers outside of IIAB as a whole.

You don't need our (IIAB) permission to relicense our software under GPL or 
AGPL because the BSD 2 clause license we are using is compatible with GPL 
forks.  BSD is gives more rights than GPL. 

That said, I'd strongly prefer no one forks our code base in that way and 
instead contribute back to the core IIAB project software (under a BSD license).

There is no reason BSD components and GPL components cannot co-exist, as they 
do everywhere else, assuming basic linking hygiene is used.  If you don't 
understand this post please don't make licensing decisions.

[Server-devel] raspi project

[Tim Moody]

I personally have not had much luck with Indiegogo as far as actually getting 
stuff is concerned, but an interesting project if rather expensive.

[Server-devel] RFC - command server

[Tim Moody]

Because I want to get to a place where running ansible and loading content can 
be managed through an admin gui, I have started thinking about a command 
server, a sort of callable job queue.

I want to give certain admin users the ability to launch commands which run as 
root and may be long-running.  Such commands should survive a restart and it 
should be possible to monitor progress.

I am leaning towards the following approach:

1. A command server based on ZeroMQ implemented as a systemd service which is 
always running as root.
2. Input to the command server is through a unix domain socket which is owned 
by root and rw only for anyone in a group whose members are apache and probably 
xsce-admin.
3. The command server uses sqlite for persistent storage owned by root and rw 
by owner.  Probably the schema distinguishes between command requests and jobs.
4. A php or python script invoked by an ajax call from the admin gui invokes a 
command on the command server. The gui would be user/password protected.
5. The command server parses the request and checks if it has already been 
requested.
If the command is new:
6. The command server logs the command into persistent storage and immediately 
returns a response with probably OK or Error depending.
7. It translates it into a shell command based on internal logic.  It NEVER 
simply executes a command it gets from the gui.
8. The command server forks a child which runs the appropriate command in 
background, returns its pid, and terminates.  The pid is put in persistent 
storage.
If the command is a duplicate:
9. The command server verifies that the command is running and to the extent 
possible its percent of completion and returns status to the caller.
10. There would also be status commands to return a list of current jobs or 
status of an active job and perhaps jobs marked active that are not running.
11. If the command server crashes or the system is restarted, the command 
server attempts to restart active jobs.

Possible commands are:

rsync-iiab-content – copy various iiab files to their destination in /library.  
The source is a parameter, but not the destination to keep from copying malware 
into /usr/bin, etc.  Some attempt would also be made to verify the source to 
prevent malicious content.
rsync-rachel-content – similar
rsynce-kiwix-content – the list could grow
runtag
runansible
reboot

Re: [Server-devel] [IIAB] iiab on xo-4

[Tim Moody]

Thanks.  This got me past the /tmp space problem, but now I have a new problem.

If for some reason,  such as mirrors unavailable, /bin/pip install -U -b 
/piptmp --use-mirrors Internet-in-a-Box fails and I rerun I get

Found existing installation: MarkupSafe 0.18
  Uninstalling MarkupSafe:
Successfully uninstalled MarkupSafe
Running setup.py install for markupsafe
  Traceback (most recent call last):

-rw-r--r--  2 root root 34 Nov  2  2007 setuptools.pth

I can also get a variant of the problem 

ImportError: No module named pkg_resources, which I believe is part of 
setuptools.

I tried yum erase python-pip python-devel  gcc xz-devel  mod_wsgimod_xsendfile 
and then reinstalled, assuming that setuptools must be part of one of these 
packages, but that did not solve the problem.

I tried yum install python-setuptools, but that did not solve the problem 
either.

Any help is welcome.

Hi Tim, 
pip builds its packages in /tmp by default.  You can specify a different 
directory where you have enough disk space.

See http://stackoverflow.com/questions/10617198/pip-creates-build-directories

pip install -b customized_build_directory to specify another directory asbuild

Re: [Server-devel] [IIAB] iiab on xo-4

I found pkg_resources.py and setuptools in /piptmp, which seems wrong, but I 
don’t know why it is there and how to cause it to install where I assume it 
should be in /usr/lib/python2.7/site-packages/.

[Server-devel] xsce-tests

[Tim Moody]

I have created an xsce-tests git repo with scripts to assist in testing the 
schoolserver.

Please look at https://github.com/XSCE/xsce-tests/blob/master/README.md for 
details.

The scripts are installed on a test XO by copying the contents of the Run-on-XO 
directory to the root of a usb stick and booting the XO with it.

This will install scripts into both /root and /home/olpc.

It has only been tested with an XO-1 running 12.1.0.

There are also utility scripts to connect to an AP and start sshd.

Hello

​I have the same problem, when i run ./runansible, always get stuck on this 
part, with same error.

Also when i run ansible-playbook -i ansible_hosts xsce.yml --connection=local 
--tags=pathagar​

Is there any way to avoid the pathagar part?



I try to set up a xsce for initial testing on Nexcom NISE 104[0] device.
