[Server-devel] Testing XS 0.5.1 Beta
I installed a new XS 0.5.1 and it seems to be working as expected. I can connect properly to the XS from sugar installed on F10 from the sugar packages. I can not connect from my XO laptop. olpc-netstatus shows I am connected to the jabber server, but it does not show anyone in the network view. I enabled debugging and I can see it shows that it finds the other sugar instance connected to the jabber server, but the logs show that the f10 sugar disconnected. I can see that both are still connected according to the ejabberd admin web pages. Note that on F10 with sugar I can see the XO laptop. Looks like the XO itself has some problem with the presence service. Where should I look to debug this further? -- Dave Bauer d...@solutiongrove.com http://www.solutiongrove.com ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
[Server-devel] Moodle on XS Install
I am using XS 0.5.1 beta. On there the moodle instance is not comfigured. Should I expect it to work out of the box or are there additional steps I need to take to get it working. The XS install docs don't mention moodle at all, only ejabberd.

[Server-devel] Gadget on XS
Hi, I am trying to get gadget working on my XS at schoolserver.solutiongrove.com First I downloaded the source and built it, but I could not find any indication that gadget was installed. How can I tell if it is working? Next I tried the gadget package http://koji.fedoraproject.org/koji/taskinfo?taskID=1261886 RPM but it required ejabberd package. RPM says this is not installed. (I did install python-twisted which was another requirement of the RPM). Does anyoe have any advice on getting gadget working? Thanks!

Ah I see, yeah I can try this and let you know. Conceivable gadget can coexist with the Moodle/Ejabberd integration you are working on. We are also contemplating using this as a public collaboration server, so we are not following the XS recommendations completely.

Tried this based on the documentation you added
less /etc/gadget/gadget.config
server_host = 'localhost'
server_port = 5560
domain = 'sugarlabs.org'
password = 'X'
roster_path = 'gadget.roster'
ejabberd-xs.cfg
{5560, ejabberd_service, [
{ip, {127, 0, 0, 1}},
{access, all},
{host, "gadget.localhost", [{password, "X"}]}]}
Same result in the gadget log. Restarted ejabbderd and gadget services.

[Server-devel] ds-backup.py backup_url server check
Hi, I have updated my XS to the lastest code and I have the ds-backup server code on there. I have ds-backup-client on my client (slightly modified SoaS). Now I am investigating how this works and I am reviewing ds-backup.py to see why my backups are not working. I am looking around line 114 and I see this backup_url = 'http://schoolserver/backup/1' I see that the serial number from the client is appended to this. I don't see anything on the XS that responds on this URL. Should this respond or do I have the wrong version of this script or I am confused? If something should respond on this URL, is it part of Moodle, ds-backup server or something else? Thanks!

Upon further research, i added a print e.code into ds-backup.py I see I am getting a 403 unauthorized response from the schoolserver. This is on a registered client that can get into moodle using the browse.xo magic cookie. I am not clear on how authentication is supposed to work with the ds-backup code.

[Server-devel] 503 Error, library full when running ds-backup.sh
I tracked down a problem backing up SoaS. We have working registration and ds-backup client etc. I was getting a 503 error from the backup-available.py. This was the result of /library/ being full. I checked and /library/ is only 30 megabytes! Is this expected. I setup this XS on an 8G disk with 4.7G free after install. Is there an easy way to expand this? It looks like its LVM. I can create a new volume and map it to /library/ if necessary, but it seems the 30M default is pretty small.

[Server-devel] Aliasing and backup
Ok, I am asked here after I read the XS Blueprint for account aliasing, I am not sure I am thinking about this the right way. I registered SoaS and generated a backup and its available from Moodle just fine. I later register another SoaS and go to the the old registration, click the alias tab, choose the new registration and click the Alias this account button. I login to the XS from the new registration and an logged in automatically. I go to my backup tab and it says this user has no backup data yet. As an experiment I also tried aliasing in the opposite direction, going to the new user, clicking that alias tab and choosing the old user to the same effect. Should the backups from the original account show up on the new aliased account?

It prefills in my login name as the aliased user instead of the new username and my magic cookie doesn't work anymore. I guess its changing the username when I try to login and it doesn't match.

How many did you setup and what technique did you use, Bridged, NAT, Internal for each one? Also if you execute "ifconfig" from the terminal within the XS VM what is the output? This should show what addresses the interfaces are listening on. I just had another idea. netstat -an | grep 80 should tell you which IP address the Moodle server is listening on. It is on port 80. You'll also see port 8080 for the idmgr service.

Re: [Server-devel] Gadget on XS
Success!
I did a new XS 0.6d2 install and added the gadget RPM. I configured it
correctly an gadget is running and I can see gadget communicating with
Soas-strawberry!
I have not been able to see what is different on this install, it is 0.6d2
instead of 0.5.2.

Re: [Server-devel] Gadget on XS
Here is what I have so far:
XS 0.6
Install frm kickstart
Edit /etc/sysconfig/network-scripts/ifcfg-eth0-local for static IP
run /etc/sysconfig/olpc-scripts/domain_config
Make sure ejabberd is configured correctly
Edit /etc/ejabberd/ejabberd.cfg
Restart
ejabberdctl --node ejabb...@schoolserver start
Gadget
Get RPM
http://kojipkgs.fedoraproject.org/packages/gadget/0.0.3/2.fc9/noarch/gadget-0.0.3-2.fc9.noarch.rpm
More Info: http://koji.fedoraproject.org/koji/buildinfo?buildID=95961
yum install python-twisted
rpm -i gadget-0.0.3-2.fc9.noarch.rpm
Edit ejabberd.cfg to support gadget
Hostname is gadget."full hostname" ie
gadget.schoolserver.xsdev.solutiongrove.com
It looks like its not using gadget but local collaboration. I turned off the
shared roster and shutdown ejabberd and I think it might be using local
collaboration instead of the server.
I need more debugging.

[Server-devel] Automatic @online@ shared roster
Can I disable this for some testing with Gadget? I finally got gadget to install and run on an XS 0.6 install but no matter how I remove the Online shared roster it comes back by itself. I assume some process in moodle according to the description, (created from moodle) is recreating it. This works great on initial install it just works, but for testing is gadget works, I am not sure if the shared roster or gadget is being used.

For my specific application, I will be using the Moodle/ejabberd combination, but as someone asked, I figured I would try it out and see if gadget worked.

Re: [Server-devel] Automatic @online@ shared roster
Thanks, I figured it must be some cron thing since it kept coming back every couple of minutes. I can track it down from there. I am just doing this to try to understand what gadget is doing.

OK, we can workaround this two ways, Use schoolserver as the jabber server name in the settings then 1) set the IP in /etc/hosts as a quick hack to make sure things work 2) set up the SoaS to use the built in DNS on the XS. Using the DNS seems problematic, probably due to my lack on knowledge. If we do that we need to defer to the network DNS for everything except the schoolserver hostname. If kids take the stick home, what happens with the DNS if we put the XS into resolv.conf? The SoaS is not getting DHCP from the schoolserver due to the setup where the XS is just inserting into the same LAN as the clients.

The debugging settings will also enabled logs for local collaboration, so hopefully that will give us the information we need.

Re: [Server-devel] /library partition
I am not sure if there is any documentation: It has pgsql-xs the postgresql database for Moodle users which I think are home directories for the registered XOs which will contain their backups. xs-activation, hopefully martin will explain that xs-activity-server which I assume allows you to run a server to distribute activities, and the content goes there. xs-rsync I am not sure what this is. I believe the overall idea is that anything that is "content" goes in this directory as opposed to software or parts of the operating system.

I tracked this down. In moodle/web/auth/olpcxs/auth.php where
schoolserver is set as the hostname. I changed it to use
php_uname('n') and it is working now. I'll submit a patch if you think
this is workable. It coincides with the registration patches to allow
other server names.

It was concatenating 'schoolserver' . $XS_FQDN where our XS is not
called schoolserver.

[Server-devel] Strange Presence Anomoly?
I had 3 users on an XS. One user shared Terminal Second user entered the shared terminal then stopped the shared terminal on their end. Second user can't see first user in neighborhood anymore. Third user and first user can still see everyone. Interesting. I will try to collect more data but I wanted to get this out there as something to look for.

I downloaded the file on my Mac and it got the correct mime type and offered to open the project in Squeak. I tried on soas-strawberry and XO-802 and it did not open etoys from the journal. Maybe etoys is looking for a different mime-type than x-application/squeak-project?

OK, I fixed this by adding
'pr' => array ('type'=>'application/x-squeak-project','icon'=>'video.gif'),
to lib/filelib.php in moodle. Looks like our version of XS did not support
this mime type for forum uploads in moodle. This should be an XS 0.6
install.

It looks like line 113 does not work it gets in error when you do not have any battery and the command hal-get-property --udi $B_HAL --key battery.charge_level.percentage returns instead of a numeric value, the help for hal-get-property.
