9 A good starting point may be taking a look at the kernel IP routing
10 table -- that's what "route" is for. You probably want to use its "-n"
11 switch to disable host name lookups.
12
13 You want a route with destination 0.0.0.0, genmask 0.0.0.0 (means CIDR
14 network 0/0, or "default" upstream) and gateway somewhere in the range
15 24.88.247.x (24.88.247/24), going through (iface) eth1. Without it,
16 your system will not be able to talk to anything outside of your
17 little corner of Road Runner's network.
18
19 If you have such a route, then running traceroute (also with "-n")
20 towards a known valid IP address should give you some clue as to where
21 the problem is. You may also want to look at any iptables rule sets
22 you may have; that's "iptables -L -n" (list, numerical).
23
24 If you can connect to an IP address but not using a DNS name, that
25 leaves just name resolution (/etc/resolv.conf and /etc/nsswitch.conf
26 under "hosts:", as I recall).
