The script which performs network configuration (olpc-scripts/network- config) is separate from the script which performs network configuration at first boot (init.d/olpc-network-config) to allow manual operation and simplify debugging. It is not called by any other script. >> On Thu, Jul 3, 2008 at 12:09 PM, Tim Moody <[EMAIL PROTECTED]> >> wrote: >>> /fsroot.olpc/etc/sysconfig/olpc-scripts/network_config closes the >>> loop by >>> creating /etc/sysconfig/olpc_net_config, but ONLY if it >>> succeeds.

Please don't confuse mesh networking with the ability to collaborate, which works with any network connection between laptops (WiFi, mesh, wired). We currently don't recommend that any school (except for ones with less than fifteen students) use mesh networking. We suggest traditional 802.11g APs, connected to a server over wired ethernet be used instead. > because we can't get an antenna). Why can't you get an antenna ? You can request one through our developer program. Please let me know if you are having problems obtaining antennas through that program --- there have been problems in the past but we think they are fixed! > Either way, the script could probably accomodate more > wired adapters. It already knows what's there. Sure. When that script was written, it wasn't clear how long it would last (I was guessing a month, but it has been almost a year). If it isn't going to be replaced soon, adding support for three or four adapters would be easy. But all adapters beyond the first should be routed subnets, as we are trying to prevent multicast and broadcast traffic from propagating.

Disks are cheap. Why wouldn't we want testers all using the same partition layout ? The current partition layout can be critized and changed, but preserving sanity is easier with a common partitioning scheme across the XS servers. BTW, that is a one line change in the kickstart file --- you can trivially build your own school server image that lets you manually set partitions... We need another name for "mega-servers", which provide school server services, but have a different network, service/server mapping, and storage scheme (partitioning or separate disk servers) than the XS.
