[K12OSN] Two subnets

[Michael Blinn]

No, two NICs with two separate gig switches.

I've found the source of this error and have boldly moved on to others (;

Apparently, I needed a separate 'shared-network' declaration for each 
subnet. (before, my dhcpd-k12ltsp.conf had both subnets in the one 
WORKSTATIONS subnet) After this change, the client received the correct 
IP each time it requested.

However, then, I received kernel panics, unable to mount root. I changed 
the /etc/exports file to the one as is attached, though I'm not sure 
that made a difference (I defined each mount and its allowed subnets 
separately instead of using 192.168.0.0/255.255.0.0). I restarted NFS 
and did 'exportfs -avr' to ensure the changes were taken.

I DO get an OK now, though it is still trying to mount to the incorrect 
NIC. I think I've moved into NFS issues and DHCPD is now all set.

(this is a 192.168.1.0/24 client on the 192.168.1.0/24 switch and 
192.168.1.0/24 server NIC - I copied a separate i386 for the 
192.168.1.0/24 subnet and called it /opt/ltsp/i386-1)

I'll keep at it. NFS doesn't do any logging so I'm kind of fishing in 
the dark. Does anyone have any suggestions?

I hope folks don't mind me attaching and being a bit wordy about this 
issue. I'm hoping that others who do two subnets in the future may find 
it helpful to peruse this in the archives.

Cheers,
