Mohamed,
Does the gateway server have dhcpd running on it ? Is
there any chance that it is responding to the workstations
when they send out the dhcp/bootp request ?
Are you using a switch or a hub to connect the machines?
The reason I ask, is that if it is a hub, you can run
tcpdump on the LTSP server and watch the packets, and see
if the workstation is sending the dhcp request, and then
you can see who is sending the reply.
When I do that, I use the following command:
tcpdump -s 1500 -w /tmp/tcpdump.out port 67 or 68
Let that run for a few minutes while you turn on a workstation.
After a few minutes, kill the tcpdump command and you should
have a file with all the packets captured in /tmp/tcpdump.out.
Then, use Ethereal to look at that file. You should be able to
pick out the source and destination addresses of the packets.
Hope that helps,
Jim McQuillan
