PLEASE UNDERSTAND WHAT YOU ARE DOING BEFORE YOU START THIS. SAVE YOUR EXISTING CONFIGURATION FILES BEFORE CHANGING THEM. Please read my disclaimer about such things.
In the very likely event that I've misstated something here, please let me know. My E-mail address is below.
Some of the items (and in fact this page as a whole) assume you have some sort of Internet access. I'd suggest reading this whole page and getting any software packages while you have a chance. Internet access from within Linux, using Road Runner is tedious at best.
DEVICE=eth0 ONBOOT=yes BOOTPROTO=dhcp
NETWORKING=yes FORWARD_IPV4=false HOSTNAME=something.twcny.rr.com DOMAINNAME=twcny.rr.com GATEWAY=22.214.171.124
Change the third octet (the 255 here) to whatever your network number is. You need the .1 at the end (that's the address of the Cisco at the other end.) The "something.twcny.rr.com" doesn't matter, dhcpcd will change it anyway.
You should see something like: "dhcp eth0..." then "done." The PC light on the modem should be lit. If you see "failed." and the PC light goes out, something is wrong, probably with the ethernet cable. The PC light may go out when the eth0 interface is configured 'down.'
eth0 Link encap:Ethernet HWaddr 08:00:20:0C:46:D0 inet addr:126.96.36.199 Bcast:188.8.131.52 Mask:255.255.255.0 UP BROADCAST NOTRAILERS RUNNING MULTICAST MTU:1500 Metric:1 RX packets:115134 errors:1 dropped:0 overruns:0 TX packets:109135 errors:0 dropped:0 overruns:0 Interrupt:5 Base address:0x1270
Some of the numbers will be different, but the important ones are: inet, Bcast and Mask. If you see 0.0.0.0 for your inet address, dhcpcd failed.
Destination Gateway Genmask Flags MSS Window irtt Iface 184.108.40.206 0.0.0.0 255.255.255.0 U 1500 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 3584 0 0 lo 0.0.0.0 220.127.116.11 0.0.0.0 UG 1500 0 0 eth0
Again the third octet in the route to 18.104.22.168 should be whatever your network is. You should also see the route to 0.0.0.0 (the default route address) to the router (the .1 address).
