[K12OSN] dhcp leaking out eth1

[William Fragakis]

Don't know how this is happening - apparently some of our newly 
installed servers (k12ltsp 4.4.0)
are serving dhcp off eth1. Physically, it's the only connecting to the 
school network which has its own dhcp server on a 10.x.x.x subnet. eth0 
is happily handing addresses out on 192.etc and clients are working 
fine. /var/lib/dhcpd/dhcpd.leases (i hope I didn't misspell anything 
material) indicates ip addresses handed out to Windows machines on the 
school network.

Some we having fully connected and are handing out ip addresses over 
eth1, a couple are new installs without clients which are doing it.

These are supposed to be default installs with eth0 being local and 
eth1 being internet. The network config panel reads correctly. Cables 
are correct, too - or at least we double checked 10 times and it seemed 
okay.

We've done a number of identical Dell boxes as servers and only a 
couple are acting up.

Is there anything I'm missing? Any way to force dhcp serving to only 
one ethernet port?
