Flushing the IP routing table

Hi.
I set a default route for the hole system in /etc/sysconfig/network with:
gateway=192.168.0.1 below the hostname line, then restarted the network 
service.

But even now when I try and telnet to freeshell.org on port 23 I get the 
message:
freeshell.org/telnet: Temporary failiar in name resolution. Why am I still 
getting this problem? I had it working last term, and I still can't get the 
192.168.0.0 and 169.254.0.0 lines out of the table, but there is a default 
line below it.

Cheers.

Check out /usr/share/doc/initscripts-8.11.1/sysconfig.txt (or similar).
There's a load of info in there.

In short, static routes can be added in many ways.

For complex multi-route solutions, routes can be added by using the
/etc/sysconfig/network-scripts/route-<interfacename> file using:
ADDRESSn=<network address>
NETMASKn=<network mask>
GATEWAYn=<gateway IP address>

The "n" can be any integer number, but is expected to be monotonically
increasing and counting starts from 0.

If you only have one default route on the whole system, it can be
specified in /etc/sysconfig/network using:

GATEWAY=<IP Address>
GATEWAYDEV=<Interface> <--- Optional interface to use for route

Default routes per-interface can be specified in
/etc/sysconfig/network-scripts/ifcfg-<interfacename> with:

GATEWAY=<IP Address>

Hope this helps,
C.
