Re: [Server-devel] Wikiserver on XS
good thing there are brighter bulbs involved in olpc than myself :) cbj I will have to look at your code for wikislice and see how it harvests the images from wikipedia. I was having the most trouble w/ that part. Perhaps wikislice can easily be reused for wiktionary we like wiktionary because it is quite small and it has audio samples that say the word. Nepali kids seem really like the latter feature. -Original Message- From: Chris Ball [EMAIL PROTECTED] To: Bryan Berry [EMAIL PROTECTED] Cc: server-devel@lists.laptop.org Subject: Re: [Server-devel] Wikiserver on XS Date: Mon, 30 Jun 2008 12:06:51 -0400 Hi, I tried setting up a Wiktionary server on a shared server that our pilots have access to and it was a major pain in the ass. After 3 days I couldn't get it to work. I had a lot of trouble downloading and importing the images, perhaps Chris Ball's wikislices gets this right. I will have to look at the code and ask him. Oh, you mean using the wikislice technology to build a snapshot of the dictionary data from wiktionary, rather than the wikipedia data? That's an interesting idea. The wikislices are alright but they don't allow for searching for content which I think is an essential feature. Yes, they do; when you run the Wikipedia activity, there's a search toolbar that searches against the local index. (You might be confusing the Wikipedia activity with some hand-made Wikislice HTML content bundles that SJ made quite a while ago.) - Chris. ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
[Server-devel] VPN server for our project
Hi, OLPC France is plannig a project Windrose (http://wiki.laptop.org/go/Projects/WindroseOLPC ) consisting for the schools among the world participating in the project to share and publish their contents (text, images, videos, etc.) in a semi-private BLOG (likely EduBlogger). My question: has anyone experimented the fonction of a VPN network involving remote XS servers ? Our concern is to protect the privacy of the kids, allowing private areas and public areas and making the login process easier for the kids/teachers. The communication/authentification to the VNP server will possibly be organised via a local XS server. Thank you for your comments Best regards Samy ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

We have compat packages, and all pam-pgsql, etc in that repository. So, using those files won't be a problem. Also - I see you work at CommandPrompt -- so I'll throw a wishlist item I have on my list in your direction. Perhaps you, or someone at CommandPrompt has something similar. With Pg packaged, what we will need to come up with is ~3 sets of config files tuned for different memory footprints. The same XS image will be used in hosts with various memory configurations - 256MB RAM on XO hardware, 1GB on the recommended config, and high-end hosts may have more RAM. Sure, it is doable -- I can do it for you. Pg cannot take all of that memory, but perhaps 15%-20% is a reasonable footprint. The workload for Pg is mainly Moodle and MediaWiki. Ok. One of the key things for the XS is that we should not OOM, and our working set _must not_ end up in swap. And we have several services we have to run, so it's a bit of a tough diet on RAM usage. We gotta sweat every MB :-) You are right. So, please let me know when you need the config files, and also how can I submit those packages to OLPC repository.

So python-pgsql and php-pgsql are there too? python-psycopg2 is there, but not php-pgsql. The question is: Is php-pgsql already in OLPC package set? If yes, we have compat packages to satisfy dependencies. If not, I can give it a shot. ... So, please let me know when you need the config files, and also how can I submit those packages to OLPC repository. When? Yesterday ;-) - but perhaps there is no need for rebuilding the packages. What I am wondering about is what the best solution is to maintain those alternative configurations long-term. Perhaps we could have a postgresql-server-altinit package that provides an alternative init script + config files and disables the init script from postgresql-server. The alternative init check memory size, and starts with the appropriate config files. Maybe we can solve this issue during initdb process, and copy the preconfigured config file based on the memory to data directory after we run initdb. It may be easier to maintain... BTW... I must admit that I did not work for OLPC project before, so I don't know how to do things.

Re: [Server-devel] Laptop XS working
Martin/list To remind you, I am getting to know the XS using an installation on a laptop, with 2 XO-B4s and 1 XO-1, all running build 703 and G1G1 activity pack. I have followed the configuration instructions for a small school server, ejabberd starts on boot etc. I have tested the server with and without Internet access via Ethernet. I am using a prototype active antenna that obviously is working fine. I had initial success, finding that all three XOs immediately could access the server and Internet through the browser, and they could see each other in the neighbourhood, share and invite. I then registered all three, this was uneventful. The register option no longer appears on the XOs. However, the result (unless this is a red herring) is that they can all still access the server and Internet but do not see each other any more in the neighbourhood and cannot collaborate. Can you point to any lines of attack to diagnose the problem. I can see the school mesh and simple (olpc) mesh with my Windows laptop.

How could that be? But I will do so. XOs are smart enough to collaborate even without the XS, and in this case they are using the AP but not using the ejabberd-provided services for collaboration. The main difference is that it scales much *much* better once they've registered and are using it. Can you explain the importance of the domain name. I just called mine oceania.org.

Re: [Server-devel] Laptop XS working
OK, done all that, I was fooled for a while, when logging onto ejabberd via the web interface (on a connected XO) I did not realise you need to enter the full username, i.e. [EMAIL PROTECTED] I bet that will fool a few other novices like me :) Two of the 3 laptops are now OK, but the third does not find the school mesh and reverts to the simple mesh. This happened after I registered it, it then locked up and had to be rebooted.. last question is, how does one remove the registered laptop, reset the XO (I can always reinstall it) and re-register it?

Symptom: olpc-netstatus shows all laptops running gabble to a server, the ejabberd admin page shows the laptop online, but the laptops can't see one another. This sounds like the online roster isn't setup properly. Another possibility is that there needs to be a DNS entry for conference.schoolserver resolvable on the school server. (An obscure riff on this is that ejabberd uses erlang name resolution, which tends to use alternate nameserver entries more aggressively than libc. Make sure that /etc/resolv.conf only points to the local nameserver.) Can we get more details about the laptop XS ?
