Re: [Server-devel] XS procurement recommendations (new hardware - Nosy Komba, Madagascar)
I might sum up here from recent additions (replies) on this mailing list regarding current low-power server options (x86/32bit) for XS: 1) FitPC2i - Dual Ethernet, fanless, poss heat-issue (heat sink), PhoenixBIOS (no Wake-on-LAN), 12W draw (poss ~5W idle) http://www.fit-pc.com/web/fit-pc/fit-pc2i-specifications/ 2) SolidLogic - (VIA C7, 25W draw) current sys in use not available for purchase, EU options in links below http://www.logicsupply.eu/systems/intel-atom/ http://www.logicsupply.eu/systems/fanless/ deployment sites: Jamaica 3) MSi WindBox - '10 Atom D510, 4GB DDR2 - ~35W, drawback single Ethernet NIC (USB WiFi adapter) http://fr.msi.com/models/Wind%20Box%20DC500 deployment sites: Nepal, Haiti, Philippines 4) EPC-AT270 - Dual Ethernet (Wake on LAN), fanless, drawback '08 model Atom N270 (2GB DDR2) - http://www.avalue.com.tw/products/EPC-AT270.cfm deployment sites: PNG, Oceania? These solutions generally haven't changed in the last two years, in Q2, 2012 now these are the current stable options for low-power x86? If that's the reality, I assume we can make a decision around these options, taking site specific considerations into account, and plan for possible involvement (replacement) down the line (1-2+ years) with any future server development for ARM/plug/etc and what suitable working model is devised around it.

The blurb that came with it says it's capable of 2 watts standby, but we'd need to see if it can do wake on lan.

Its no longer sold (not sure why?) but uses a VIA C7 processor and is fanless. Draws 25W at the AC end of the power brick (DC 19V). Here's a list of what they offer. http://www.logicsupply.com/categories/fanless_systems A FitPC2 should work as well. It pulls 15W at the AC end of the power brick (DC 12V). The only concern I had with a FitPC2 was the heat. They do sell an after market heat sink that helps. If you wall-mount the box, you could fashion a chimney on the heatsink to create a continuous draft of air (hot air rises and will create an air column that pulls in cool air from the outside) to pull the heat away from the sink. We tested a FitPC2 (See appendix http://wiki.laptop.org/images/4/46

Re: [Server-devel] [support-gang] Restore journal from school server
No, they're not the same format - the Backup Activity (ASLO) produces an archive which can be restored Restore Activity (ALSO) (all items are completely added to target journal on restore). The backup with the old XS model (not sure if this continues with new, I believe so) can generally be seen here http://wiki.laptop.org/go/XS_Blueprints:Datastore_Simple_Backup_and_Restore I believe the past-implementation is according to the blueprint. I believe that I backed up Lubang's XS journal datastores (/library/users/Serial Number/datastore) that was in use during 2010/2011, but I don't think it has been used this year since last July's (2011) upgrade to OLPC-AU version (stalled), wasn't completed. And also we have backups of XO-laptop journals with Backup activity. I also believe I left a copy if the backups with Lubang (cc Lloyd). I will have to double check. If it's regarding OM's XS servers and their backup - see the page I linked above from wiki, and also look at backing up the file system (datastore directories) and Moodle db, and consulting the XS 0.7 devs for guidance on a potential migration (if needed) for restore single journal entry via Moodle, for example. regards, Mitch On Thu, Mar 22, 2012 at 8:16 AM, Cherry Withers cwith...@ekindling.orgwrote: Are the files saved from using the Backup Activity and the one from an auto-backup by the XS the same format? If so, can one potentially package the journal back-ups from XS and store them in USB and use the Restore Activity to restore in lieu of a full journal restore from XS at this time?

I even found a page talking about backup/restore which referenced instructions for restore later in the page, (which was a false promise). So I am being lazy and asking for help. The eKindling deployment here in the Philippines is installing school servers, and wants help using the backups they now have on the server, when they are needed. I'd like to help them, but I don't know enough, and it is not featured prominently on our wiki!

Re: [Server-devel] XS-AU registration issue Fwd: Upgrade from XO 1.5 Firmware Q3B19 to Q3B22 results to Registration Failed Error
I agree James, it should in no way be firmware related from these releases. Regards, Mitch On Mon, Feb 6, 2012 at 2:30 AM, James Cameron qu...@laptop.org wrote: In no way could it be firmware alone. I was release engineer for Q3B19 and Q3B22, and the changes are: 1. new EC firmware for battery charging improvements, 2. handling a boot failure correctly (svn 2589), Neither of these changes affect the operating system or wireless. There were no changes to serial number code.

Re: [Server-devel] openVPN on the XS
We're looking to try set this up in our new and existing deployments this year with their XS servers, the WIKI documentation would be great to point to for our local tech lead, Ferdie (Occ Mindoro, Ph) who we're waiting to hear from before we proceed with our own openVPN instance for Phils.

We've been using openVPN on the XS in India (http://bhagmalpur.wordpress.com) and Jamaica (http://olpcjamaica.org.jm). OpenVPN runs in client mode on the XS and phones home to public IP server. We have a couple of laptops with appropriate keys that also run in the client mode. openVPN runs on the server in server mode. This setup allows us to ssh into the XS from the two client laptops whenever the servers get online via DSL or GPRS/3G. openVPN takes care of the whole NAT business nicely. I know that George Hunt was trying to do this in Haiti. Not sure how far he got. We also got a suggestion to look into IPv6 tunnels (http://www.sixxs.net/tools/ayiya/). 1) Is anyone else using something like this or similar? 2) Is there a different approach to doing the same?
