Re: [Server-devel] Setting for Machine to Automatically Reboot
Thanks guys Much appreciated. The setting is in power managemenet - AC Power Recovery (turn it on). That does the trick. Regards, Brian Hall From: Reuben K.

In a particular school we are rolling it out to, powercuts tend to occur regularly. Do you know of a BIOS setting that enables the server to automatically boot when the power comes back on? This would be much better instead of us having to go down to the school to turn on the machine manually Thanks In advance, Brian Hall ___ Server-devel mailing list Server-devel@lists.laptop.orgmailto:Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel ___ Server-devel mailing list Server-devel@lists.laptop.orgmailto:Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel No virus found in this message.

[Server-devel] ejabberd eats up 100% cpu time when it should be idle
Context: bernie alsroot: beam on jita is eating up cputime :-((( bernie alsroot: are we already running the latest version with all the patches? martin_xsa says he has fixed some bugs in the fedora 14 rpm. alsroot bernie: yup, this is fedora packages. also ejabberd /var is being recreated to the initial state every day bernie alsroot: we should tell this to martin_xsa alsroot bernie: thats why I was for something else for school server bernie alsroot: me too... my experience with ejabberd has been terrible so far. but let's ask martin first... he seems confident that it can be made to behave well. bernie alsroot: i'll forward this conversation to him This is ejabberd-2.1.6-4.fc14.x86_64 from Feb 24 2011. Is there a newer release, perhaps? -- Bernie Innocenti Sugar Labs Infrastructure Team http://wiki.sugarlabs.org/go/Infrastructure_Team ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

Diagnosing your problem? Discussing it on the ejabberd mailing list? Well, I assume OLPC people did it many times before me, I just reused their experience tryinhg to follow wiki.l.o docs and using native packages from fedora. Yes -- everytime we saw a perf problem we diagnosed. Right now we don't see performance problems when load testing the XS. What's the exact binary package of ejabberd and configuration that works well? How many users has it been tested with? I've had similar an experience similar to Aleksey with all versions of the ejabberd I tried, and so did the Collabora people I spoke with. I tried tweaking the configuration a bit, but the impression I got is that ejabberd is over-engineered for our needs (only 1 server, about 1000 users). If you see perf problems in your specific setup, I can only suggest you diagnose -- perhaps with the help from the ejabberd developers via their mailing list. Thanks.

Putting a wireless router an AP in the middle with a default route to another XO on a separate subnet running some XS server code that in turn connects out maybe the USB ethernet port to the WAN might work. Without some real router protocols active, hairpinning issues will also arise if you try to just hook back to the same subnet. So bottom line (unless I'm way out of the loop in ancient history - which sometimes happens) , is that from what Peter is saying, if you already have an acceptable infrastucture which is currently working on an XO 1.5, then there is no reason for it not to work on a 1.75. However it would be my prediction that if you were hoping to have a vanilla XO 1.75 now run as a WAP, that may still not be as simple as you want.

Please see http://wiki.sugarlabs.org/go/Sugar_Server_Kit for more information on the software that will be running on the school/classroom server. The Sugar Server Kit modularized the existing OLPC-XS and provides a community level 'tool kit' for creating a school or classroom level servers. The Sugar Server Kit Provide a split between the community level project (Sugar Server Kit) and any number of downstream solutions based on the community project. This should stimulate the downstream community to contribute to this upstream community project, facilitating reuse of its experience in all other downstreams; Treat the community project as a collection of useful tools, created and supported by community contributors, that might be composed into a final deployment solution on purpose, i.e., Sugar Server Kit is not an OS or a final solution, but rather a bunch of tools that might be launched on any major GNU/Linux distribution at the deployment level. And because some of these tools might be implemented in several ways, it should make the acceptance process of new features by upstream more flexible; The whole system should be as reliable as possible. Thus, the community project will provide a decent testing environment (several levels of automatic and human driven tests at the top level), which might be used not only for Sugar Server Kit itself, but for deployment solutions as well. david Once all the XO buddies (XO 1 and 1.5) atttach to a 'real' AP, all machines on that AP can see each other, and get out to the Internet through the AP's running as a router.
