Environment: Mandrake 7.1 (CD-ROM) Linksys Router (which does DHCP) Linksys NIC CableModem During the installation of I selected dhcpd/bootpd and left the IP address blank. When I finished the installation and rebooted for the first time it brought up eth0 ok [ PASSED ], but when it went to grap an IP from the DHCP server (the router) it failed. The two windows machine handle the DHCP fine so I know, I assume, that the DHCP server is working... After I logged in I used DrakX to try to reluctantly specify an IP address: 192.168.1.103 (the other two (Windows) machines are .101 and .102 via DHCP). Thought DrakX didn't complain or show an error this didn't worked. So I tried adding a gateway: 192.168.1.1 No error, but didn't work either. Then I went to the command line and typed ifconfig all I get back is something like: [root@tux /root]# ifconfig lo Link encap:Local Loopback inet addr:127.0.0.0 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:3924 Metric:1 RX packets:12 errors:0 dropped:0 overruns:0 frame:0 TX packets:12 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 I didn't see eth0 and I didn't see the loop back address 127.0.0.1, only 127.0.0.0 - i'm at a loss here. When I typed route all I saw was something like: [root@tux /root]# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 127.0.0.0 * 255.255.255.0 U 0 0 0 lo Then when I tried for fun to add a gateway by hand: route add -net default gw 192.168.1.1 dev eth0 it says something like SIOADDRNORT or something... I've read 3 or 4 HOWTO about setting up the ethernet stuff, and none of it has helped me. Any suggestion on how to trouble shoot this. How can I determine for sure that the OS is seeing my NIC?
