The server is now coming up with the desired static address from a cold boot. I was going to test again with my SOAS but unfortunately the stick got corrupted.

Dear Martin, Greetings and a Happy New year. The XS 0.6 is loaded on a Dell computer for the Sichuan deployment. I never been in person for Sichuan or Bhutan deployment to experience firsthand how well it work. I will try to see if I could get details from those who were there doing the real work. A photo of the XS and with the Altai A3 Smart WiFi sitting on top.

Hopefully that data is still available. In the case of VMs you need the resources allocated to the VMs rather than the hardware specs as the hardware specs don't really mean much.

Re: [Server-devel] We need: examples of XS hardware in use --
Hello Martin, Happy New Year ! We run our XS inside virtual machines. I have XS inside virtualbox on my Lenovo T61 laptop Santa Rosa Core 2 DUO 2.0 Ghz 4GB DDR2 120GB HDD while Solutiongrove runs a couple of XS installations inside VMWare ESXi (http://www.vmware.com/products/esxi/). I'll try to get the hardware info where ESXi is installed from our service provider. ESXi has these fancy charts and graphs on usage and stuff about the virtual machines running, I'll see if it's possible to extract that info for you. Hopefully that data is still available.

List, David, Reuben, We are getting increasing enquiries "what hardware can we use for an XS in a school with N laptops?", and frankly the http://wiki.laptop.org/go/XS_Recommended_Hardware is a bit slim on concrete recommendations. So I need your help -- I've added some info in the "hardware known to work" section, but I'd like David to put more info on the exact model of MSI Wind he's using, additional hardware, number of laptops supported, and any extra notes. Similarly, Reuben, I need more info on what hw the OLPCCorps crowd is using. And anyone else that's running an XS (hi Hamilton!)... we need your hw profile and your numbers. Additionally, I've added a 'server sizing' section. It'll be great to get corroboration that the CPU/RAM to number of users match what you are using in the field, and whether your server gets in trouble when usage spikes. 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

Training > teachers on Learning4Content in the capital and then having them return with > no chance of practicing their new skills is not a good policy. 100% agreed. Several points here on the technical side; - It should be rather easy to get mediawiki going on the XS - yum install your dependencies, get the php code, etc. In fact, "yum install mediawiki" will get you v1.14.0 (which may or may not be current enough for your needs). Either way, you will probably need to do some apache configuration (make a new file in /etc/httpd/conf.d ) And the "vanilla" mediawiki will want to use MySQL which comes with its own warning stickers. - Whether wikieducator publishes their database in a format you can use to run an "offline server" wikieducator, that's for them to answer. Feel free to insist -- it's definitely worthwhile content. Watch out for "content" that is merely an external link -- it'd be a cruel tease in an offline environment. - Wikieducator may find it easier for themselves (and for users of the content like us) to export a *static* version of their content -- Wikipedia does this every month or so, see http://en.wikipedia.org/wiki/Wikipedia:Database_download -- specifically the reference to "pages-articles.xml.bz2" If you do any (or various of the above), do share your "steps to setup" on our XS_Techniques_and_Configuration page :-) 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
