[Server-devel] Permissions in /sys/class/net/msh0

Hi All,

I've been at this for days now and am only emailing out of desperation.  
I'm on server build 161 (the 163 install didn't work on my hardware), 
though I enabled the testing repos to get what I hope is closer to 163.

Anyway, I finally managed to trick the server into seeing a msh0 
device.  I've got 3 NICs - eth0, eth1, and msh0.  I put HWADDR=<mac 
address> for the third NIC in the ifcfg-msh0 files.

Now that I've got /sys/class/net/msh0, the olpc-mesh-script wants to run 
at boot.  Which is great!  But, something's the matter with the 
permissions.  On boot, when it tries to echo 1 > 
/sys/class/net/msh0/anycast_mask, permission is denied.  I can't even do 
it manually.

I'm guessing there's a udev rule somewhere that needs to be edited or 
added.  Any ideas?

The reason I'm doing this is to try to see if I can get a school mesh 
portal point to work with off the shelf hardware.  If anyone has an 
easier way to do that or can point me towards the documentation, I would 
be grateful for any assistance.
