Hi all,
I am using kubuntu 8.0. The following problems am facing,

To stop a network we use
/etc/init.d/networking stop - I can ping after stopping.(so it is not working.)

Also anybody know how to replaced the gateway. I used the "route add" command but it is adding it to the table, what i want is replaced the old gateway with new one.

Thanks,
Renjith

You may need to do one of these to see what's happening with your network: tail /var/log/syslog

Replacing the gateway can be done with the ifconfig (/sbin/ifconfig) command. Read the man page for it to see the syntax used.

http://linux-ip.net/html/basic-changing.html seems to be a pretty good place to get some additional information regarding the use of ifconfig.
