On Wed, Jun 17, 2009 at 3:02 PM, Daniel Draked...@laptop.org wrote: The teachers already had their XOs at this point The teachers have XOs and the kids don't yet. Correct? I think this is basically a conflict between the case when you are installing 1 XS (in which case what you are describing is perfect) vs 10+ of them. I am still wrapping my head around the workflows applied in each school to deploy 10+ schools... Having to connect up other computers and open web browsers But... but... OK, these are my assumptions: 1 - You do send a technician (or more) with the XS + AP plus some cabling 2 - The technician will have to open a browser, assoc to the AP, open Browse.xo and visit the XS homepage as a basic QA step. A technician cannot leave a school without having tested the connection to the XS at least _once_. 3 - As part of #2, the technician registers the XO that will be the head teacher's machine. If the head teacher already has an XO, the technician borrows it. Otherwise, the technician grabs a random XO, registers it, and hands it over with a bit of ceremony to the head. This is a social thing: the technician should do something to stress that the XO is special. And command-based interfaces can be more easily automated by the deployments. Except that you don't know what to automate. As you said, you don't know what XO will the head teacher get. What's the SN? UUID? Here's a possible approach: Right now we can't tag anyone in any role until they've registered. In fact, early in the installation we don't really have a complete Moodle DB. So a command in the style you requested doesn't have much to work on. On the other hand, if you do know the SN, it would be relatively easy to make a list of 'blessed' SNs, so echo SN1234567B /etc/moodle/coursecreators would be a way to handle it. And the presence of that file signals that the 'first come is coursecreator' feature is immediately disabled. In my experience, even with instructions this would not happen according to plan. It really needs to be in the control of the team doing the infrastructure. Or the technician handling the setup @ the school? Is that still an unreasonable expectation? cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

Does it really make sense to rely only on Moodle being on the internal network to provide security? You are right, and a lot of my pre-OLPC work has been in making the largest of those installations work smoothly in scale, security, performance, customisations... In those cases, Moodle is a webapp. In this case, however. Moodle is the central UI for most things XS. Some things XS change how the XS behave. For example, I am drafting a bit of code that will let you configue eth0 and 'domain_config' from a Moodle-based UI. So on first boot, the XS comes up in a special mode that lets you set those 2 things. Once this work is done, you no longer need to login as root. Ever. On the other hand, it'd be serious trouble if Moodle started listening on the public address. Right now Moodle seems to be reasonably meek... but I haven't thought that through actually, it may have risks too. The bottom line is: Services that are on the LAN address have not been designed to be on the WAN address -- many (most?) of them are a security risk if exposed to the WAN today. As the XS evolves, _more_ services will pose a risk if exposed to the WAN. So -- put your test/dev machines on the LAN to play with things. The XS will hand out DHCP leases to non-XOs, you can create normal user accounts in Moodle (from the 'course creator'-blessed XO) so that things work. Using non-Sugar XMPP clients (mostly) works too if you're on the LAN. hth, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

Thanks! Makes sense. (I've been away for a few days as you've probably noticed. Now I am trying to get XS-0.6 out of the door, which simplifies all the process significantly.) The page now explicitly states the XS position on DNS - i.e. don't need to do anything because the XS does it for you. However, some people may want to use ISP dns servers. It would be nice to see instructions for such users, but the current ones were incorrect. (the way to do it would be to configure bind to send all requests to an upstream server.) Yes. We need a canonical list of the names that need to be set on the external DNS. I am personally confused by issues surrounding hostname resolution of the local server. Deployments will usually make up hostnames, right? The expectation is that they'll make up the leftmost bit of the domain name, so that the _hostname_ is always 'schoolserver'. In which case they don't resolve on the out-of-the-box XS setup, yes? Does ejabberd really fail if it can't resolve the hostname? In Paraguay, we modified /etc/hosts on all XSs as follows: 127.0.0.1 schoolserver.escuelaXX.caacupe.paraguayeduca.org schoolserver localhost.localdomain localhost i.e. we added the FQDN (as stated in /etc/sysconfig/hostname) to the very front of the 127.0.0.1 resolution (must be the first entry, because I couldn't find any other way to get hostname -s and hostname -f working correctly), then we added the unqualified hostname schoolserver. On 0.6 the domain_config scripts do that as well, IIRC. If I remember correctly, this was done in order to make puppet work. Maybe these are puppet and ejabberd bugs, but it doesn't seem unreasonable for applications to require the local hostname being correctly resolvable and the hostname being correctly output by the hostname program. Yep. Though there's a bit of trickery in that schoolserver != localhost. Finally I commented out the instructions explaining how to fix ejabberd when the user changes the hostname, because they were incorrect. The solution would be to re-run domain_config and then fix the Mnesia DBs, but I'm not sure if re-running domain_config is advisable or if a certain flag needs to be used or something. It would be nice to see these instructions return if someone is in-the-know or can experiment. Alternatively we could wait for XS_0.6 as trac suggests that this is no longer an issue.

The Linksys routing table is: Once you get it to be a bridge, packages will just be copied (bridged) over, instead of routed, and this will be a non-issue.

Re: [Server-devel] Fwd: Simple Digital Library Index System
This sounds interesting. It is something I was hoping to implement somehow, using IMS-CP (or similar) plus a repository scheme copied from the Debian apt repository format, or the yum repo format. Both repo formats are fantastic for this, very rsync, http and cache friendly, super-scalable and distributable, etc. The plan was (is?) to use the upcoming Moodle v2 repository plugins infra to build client and server sides, but with the protocol being just a trivial-looking repo format, any existing system can be a server. Unfortunately Moodle v2 will take a long time to be ready. (I've reviewed GreenStone in the past, and worked with Fedora - the _other_ one - , eprints and a few other ones. I was not impressed with any of them.) Not sure how this project is designed and implemented. If it does something like the above, fantastic. It'd mean that the software maintains the repo (which is served by bare apache), but does not need to be running permanently. The resident memory footprint of Java is a bit of a no-no for the XS. In any case, it might need client code for the Moodle side so that the content is easy to integrate into the topic of the day and learning narratives... cheers, m On Mon, Jul 27, 2009 at 6:39 PM, Sameer Vermasve...@sfsu.edu wrote: -- Forwarded message -- From: Mike Dawson mikeofmanches...@gmail.com Date: Mon, Jul 27, 2009 at 1:03 AM Subject: Simple Digital Library Index System To: de...@lists.laptop.org Dear All, In Afghanistan we wanted to have a system that would make it as simple as possible to make a relatively large, replicated digital library accessible locally on the school server (external bandwidth here is about 64kbps per school).

It seems to me that the basic functionality is already in Moodle, in that activities can be presented or not to a Moodle user depending on his group memberships. On investigating how Flash content can be embedded in Moodle, I found that (1) Moodle supports SCORM and (2) a lot of Flash eLearning content is actually packaged as SCORM. Yes. And yes. My strong recommendation is to target SCORM. A fallback option may be Matt Bury flash module, but it is not recommended. So, what we're proposing to do first is take some Flash videos, embed them in SCORM objects, put them in Moodle and looking at how the groups/permissions features of Moodle can be used to manage them. Sounds good -- do remember that the XOs don't normally ship with fullblown Adobe Flash, they ship with Gnash. Targetting gnash is an interesting area, one where I'd like to hear more about. If you talk nicely to them, the Gnash developers will be very keen to help too. I've also installed the XS server software on a PC and our networking people are setting it up so later we can test with an XO accessing Moodle on the XS. but it seems to me that we could be doing this work on on a plain vanilla Moodle installation? If that is the case, perhaps discussing the project is off-topic for this list? Sounds right to test and debug it in a vanilla Moodle first. We do customise some stuff, but nothing that breaks the main APIs. Things to keep in mind: - If you write Moodle code, don't rely on admin (or on the 'doanything' capability). We don't give our users the 'admin' account. The workflow to setup, manage and use the content must be doable with non-admin roles.

It would be a win for Get Satisfaction if we did this because it would be a great case study for them to write up. Would this be enough of a win for us to be worth doing?

Re: [Server-devel] [Sugar-devel] Jabber Testing Monday Aug 24
Hi Caroline, sorry about the delay -- catching up on XS things now -- enormous thanks for the report. So controlling for Gadget and reg'd numbers, it seems that the ejabberd version (or perhaps other XS compoment) version makes a difference. The ejabberd upgrade was very significant, and the rework of the 'online' patch was also fairly important (I assume you are using the 'online' SRG as it's the 'default' config). In terms of Sugar preferring salut, and having to restart... - Maybe there are connectivity issues (high latency?) to the XS? - If connectivity to the XS is good, it should be enough to wait, as I've seen Sugar (0.82 at least) try Gabble every once in a while... - If waiting is not enough, it should be enough to reconnect to the AP. That definitely triggers a Gabble connection attempt IOWs if you do have to restart, there maybe a regression there... Overall, I find the relatively fast Telepathy switching a bit frustrating as a programmer, but I've seen how it's useful in real world usage. All I would ask for -- should a genius-in-a-lamp ask for my wishes -- would be some subtle UI hint. Maybe a variation on the quater-arcs that mark the connected AP or something like it... cheers, m On Tue, Aug 25, 2009 at 5:18 AM, Caroline Meekscarol...@solutiongrove.com wrote: Again we are working with XS1 - responding to jabber.sugarlabs.org.

When we stopped sharing the TA it dropped back down. We then shared a chat and CPU again rose to 100%. Next we switched to testing on XS2. Sharing Turtle Art and Chat did not spike the CPU. We felt there were 4 differences between XS1 and XS2 The number of registered users XS 1 is an older version of the XS 0.5.2. XS2 is 0.6beta XS 2 has Gadget XS1 had about 20 users logged in XS2 had 4 or 5 Next we turned off Gadget on XS2 and repeated our test. No CPU spike. Thus we think #3 is unlikely to be the important difference. Next we deleted the registered users on XS1 and switched our testing back to XS1. When we shared TA and chat there was still spikes up to 100% CPU. Thus we think #1 is unlikely to be the important difference.

But I don't think its our right now solution for the work we are talking about doing. 1. Our target, elementary school teachers are not currently using either Moodle or Sugar, adding both at once makes the learning curve even harder. Adding a 3rd system... easier? 1. We are focusing on lesson plans in the 1 hour and even 20-minute groupwork time frames. Moodle is more focused on longer time frames. I am about to include José Cedeno's new 'timeline' courseformat which should make classroom usage a bit better :-) 1. We are focusing on what the teacher will do and what the class will do both online and offline during the lesson as well as learning goals, standards, help for the teacher in differentiating the lesson etc. Think the teachers guide for the text book. Moodle is more focused on what the student is doing online. Its not a very natural fit. That sounds a lot like the paper-based materials Peru is putting together. A booklet for the teacher that guides a (probably multi-day) lesson called XO-Reporter that covers lots of things, from choosing a topic to report on, asking good questions, writing in news style with inverted pyramid -- some parts involve using the XO. http://www.perueduca.edu.pe/olpc/archivos/Fasc_PERIODISTA.pdf More like that (though of varied depth) http://www.perueduca.edu.pe/olpc/OLPC_fichasfasc.html For new teachers, and in agreement that we are snowing them with a ton of new things, these docs seem to be most useful _on paper_. I cry a bit for the lost trees, but we do need these stepping stones. And heck, I like my key guides / books / references to be on paper. If things to aid support computer use want to use the same screen I am trying to use for something else, it's a losing proposition. 1. Moodle has tremendous promise in terms of reducing teacher workload. Here is an example of what I hope that in the future Moodle will be able to: 1. Provide a link that students click and they open a Write document that is a template/scaffolding for a specific assignment, say writing a scientific argument. I have _just_ published a Moodle update on Friday that should do this. If a teacher creates a template and uploads it as part of Moodle topic 1. When the document is saved it is automatically turned in as Homework in Moodle allowing the teacher to review and comment on the document from anywhere, even on days when the class does not see the science teacher. That's a bit harder :-) but doable. However, I still see Moodle as just one format teachers will use.

Yes, you can segregate what XOs see in the neighbourhood view by moodle course membership. This is mainly useful when you have schools with more than ~50 XOs. Quick howto: 1 - Make sure you are using a recent Browse.xo (101 at least, I think) 2 - The first XO to register (reboot) and visit moodle successfully gets some extra rights (is an 'admin' of sorts). So get an XO reg'd and visiting Moodle -- it will auto-authenticate into Moodle. Should see a 'site administration' block on the left. 3 - Create some courses (Site Administration-courses-Add/edit-Add new), assign teachers and students. In the long and confusing new course form, all you need to set is Full Name and Short Name. Please ignore every other option. Note: when it comes to enrolling, setup some courses for XOs you have registered already -- this is mainly to have something to work with! You can add more courses enrolments later. Might help: http://docs.moodle.org/en/Enrolment#Manual_enrolment 4 - In 'Site Administration', go to Courses-Presence Service, and set presencebycourse to Yes. 5 - Within 10 minutes, issuing the same ejabberdctl queries as above should show that Online has been replaced by several SRGs -- one per course. Asking for the 'info' of those, will show you their membership. 6 - When you make the switch from one mode to the other on the XS side, the situation will be confusing for the XOs, so they might need to re-associate to the Access Point (so they re-query their group membership) before they see the changes. Note: All changes to the course membership take 5~10 minutes to appear in ejabberd on the XOs, and some changes may also need an XO to reassociate to the AP. Emphasis on 'some' :-) Dan: service pgsql-xs supports chkconfig, but is not reerenced in any runlevel (run 'chkconfig --add pgsql-xs') Should I run this as it says? Yes! and then restart the server. Both pgsql-xs and moodle will start up. On this first startup, moodle will perform its setup (so it'll take a tad longer). You can see the log of the install in /var/log/moodle/instupg.log klogctl during boot returns 'invalid argument' dunno mshbonds and wmeshs do not seem to be present normal. could not connect to server postgres as well. not normal but you'll have it fixed for the next reboot :-) m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

There is a 'postgres' service too. That should be stopped. The result is a page stating: Moodle is disabled at the moment. That is because Moodle is having trouble starting up -- and that is all about getting the 'pgsql-xs' service going, and the initial moodle setup running. Some more debugging: - Does the file /etc/moodle/needsupgrade exist? (It should :-) ) - Does the file /var/log/moodle-instupg.log exist? You'll want to look at it. Lines with 'PHP Notice' are safe to ignore, you should see lots of SQL, and a final line saying [Wed Sep 16 05:12:57 EDT 2009] Finished install / upgrade - Success. That file probably has the secret to your woes... - What happens if you do...? /etc/initd.d/moodle stop (bash -x /etc/initd.d/moodle start 21) | tee moodleinit.log The 'tee' command will show you the output but will also save it to the moodleinit.log file. So I am hoping you can post your /var/log/moodle-instupg.log and moodleinit.log files so we can debug further. We've been digging around (but not changing) /etc/httpd/conf/httpd.conf and /etc/httpd/conf/httpd-xs.conf That should not affect things. If moodle is showing you the Moodle is disabled at the moment msg, the apache config is doing its job just fine :-) and they both point to a document root of /var/www/html we are overriding it -- see the /etc/httpd/conf.d/ directory :-) Does this have anything to do with our problem? I don't really know what I'm doing...

I had to re-read your logs a bit. In brief: I made the mistake of reading the moodle-instupg.log bottom-up, and thought the install had become corrupted. But re-visiting it, I realise that the error that is key here is the failure to connect to the Postgres server. psql: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket /tmp/.s.PGSQL.5432? So we need to make sure that the pgsql-xs service is running, and that it accepts connections from Moodle (that is, from apache). Some commands to try (and the correct output in my test XS) # check that the postgresql service is *not* set to run as it will conflict w pgsql-xs $ chkconfig --list postgresql postgresql 0:off 1:off 2:off 3:off 4:off 5:off 6:off # should say that the server is running $ service pgsql-xs status # should give you a list of databases - see how moodle-xs is owned by apache $ su postgres -c '/usr/bin/psql -l ' List of databases Name| Owner | Encoding +--+--- moodle-xs | apache | UTF8 postgres | postgres | SQL_ASCII template0 | postgres | SQL_ASCII template1 | postgres | SQL_ASCII # check that you can connect as the apache user and list existing tables $sudo -u apache psql moodle-xs -c '\d' List of relations Schema | Name | Type | Owner +-+--+ public | adodb_logsql| table| apache public | adodb_logsql_id_seq | sequence | apache public | mdl_assignment | table| apache public | mdl_assignment_id_seq | sequence | apache public | mdl_assignment_submissions | table| apache public | mdl_assignment_submissions_id_seq | sequence | apache public | mdl_backup_config | table| apache ... Can you try these commands?

To celebrate! - Your moodle-instupg.log file now will have new stuff, showing that Moodle connected to Postgres and created all the relevant tables... - Moodle should be working now! :-) If Moodle is not working now, post the moodle-instupg.log again, and the verbose log of starting moodle (same procedure as yesterday).

Strange that the DB would have been in a stage where Moodle cannot get it going, and does not give a meaningful error.

[Server-devel] xs-activation update, and antitheft howto
In the last few weeks I wrote up several procedures related to activation and antitheft tools in Spanish. I now had a chance to write it up in the wiki http://wiki.laptop.org/go/Antitheft_HowTo Together with the writeup, there is a small update to xs-activation so recommended: yum --enablerepo=olpcxs-testing install xs-activation cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
