[K12OSN] The Dreaded DHCP on port 1067



Hello,

I've been fighting with my LTSP server for a long while now, and I could
use some advice.  My school is such that I can't put the thin clients on
their own hub/switch... instead I need to share the LAN with another DHCP
server.  With this in mind, I have:

(1)  Set up the server to use DHCP port 1067 (following directions to make
this work in dhcpd.conf and dhcpd files.
(2)  Set up the etherboot floppies correctly to look for port 1067.  I
want to use floppys so I can use the machines "normally" as Win95
machines, or with LTSP at the drop of a floppy.

The clients seem to make the first DHCP request OK, and everything is fine
until later in the game (and much screen activity later) when I see
"Running DHCPD on port 67" and then "Kernel Panic".  This is after IPs
have been picked up, etc.

Another added issue is that use of "ethtool" shows me that one NIC is in
full duplex mode, while the second is in half duplex mode.  I think I've
solved this by adding the following commands to /etc/rc.local:

ethtool -s eth1 speed 100 duplex full autoneg off
ethtool -s eth0 speed 100 duplex full autoneg off

Checking eth0 and eth1 after these commands are executed shows them both
in the same mode.

Anyway, any help would be appreciated in getting DHCP to STAY with port 1067.

PS:  Here is some command window output in case it is useful:
