can not get IP for eth0

view full story

http://www.linuxforums.org – I am trying to get networking up on an old PII which I have successfully installed with Fedora Core 4. There are link and activity lights on the onboard interface. The controller is a 3Com PCI 3c905 Boomerang 100baseTx using address 0xdc80. The driver module, 3c59x, is loaded as well as the mii module that uses it. There is an ipv6 module loaded but it is not clear if there is or is needed an ipv4 module. eth0 is sharing an interrupt with the UHCI controller. That should not be a problem. When I drop to console and runlevel 3, and call dhclient, which is installed, I get message telling me there is no offer to the dhcp request. But I am fairly certain there is not a problem on the router/switch side. Does anyone have an idea what might be amiss here? (HowTos)
