How do you find LAN machines with dhcp?

Yes.. thanks.

This machine is your DNS server correct? Perhaps you need to put its own IP address in the /etc/resolv.conf ?

Hmmm... good point. I'll look into that tonight when I'm back at that machine. Thanks.

That didn't work. The error message is "network is not reachable". And it doesn't matter whether I try to access a name or a hard IP address.

"network unreachable" is typically a routing issue. Can you ping your gateway?

Yes, I can ping 192.168.1.1 which is my gateway.

try netstat -rn

KevinJ · 11-19-2002, 09:35 AM

any chance your gateway is restricting access some how?

I don't see how my gateway could treat this one machine differently than all the others - but maybe it is.

Here is the output of netstat -rn:
# netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 40 0 0 eth0

Why does it show my gateway as 0.0.0.0? That can't be right, can it?

I have it working now. I had the gateway set incorrectly in the one dhcp server machine. Once I fixed that it could see the outside world.

I can't thank you gentlemen enough. You have been most helpful and most patient. The users are one of the main things that makes Linux GREAT.
