can't find (windows) dhcp server w/ fedora box

[sbontrager]

I've installed fedora on a box to use as an internal web server (apache) for our organization. I use a Windows Server 2003 box for a dhcp and dns server. I've had no problems w/ our AIX servers or any workstations getting IP addresses from the dhcp server, but can't seem to get fedora on the network. I know the ethernet card is good, the cables and ports are also all good. If I use a static ip address for the fedora computer it appears to work (ifconfig), but can't get on the network. dhcp gets no ipaddress at all. Any clues?

Time to start troubleshooting. You've already covered the obvious physical connections. When you do set an IP, can you ping the dhcp server? Confirm that there is a route between the two. Firewalls shouldn't make a difference, because this is an outgoing dhcp request to an internal server.

Have you tried the graphical network config tool (redhat-config-network)? Main Menu > System Settings > Network. Select a device and edit to be sure dhcp is on. You can manually set dns there as well.

No, can't ping. I disabled the firewall. Used the graphical network tool, tried setting the ip manually, through dhcp, virtually every setting there I could think of. I finally got it to give the correct broadcast address when i run ifconfig, but i still have no network connectivity outside the box. Incidentally, the port light is on on the hub, indicating it's reading my ethernet activity on the linux box.

Can you maybe post the results of /sbin/dhclient? Perhaps you need to add the dhcp server to your /etc/hosts.allow or something like that.

I would start perusing through /var/log/messages and other related logs. See System Tools -> System Logs for an easy to parse interface.

Is the default gateway set? Post the output of /sbin/route to cehck your routing tables are ok.

Not being able to ping the dhcp server is the source of this problem. How far does /usr/sbin/traceroute (or xmtr) get on its path to the dhcp server?

[sbontrager]

attached are the results of /sbin/route and /sbin/dhclient. Please give me some instruction on how to run traceroute. Many thanks for your help.
