The method differs if you have a dynamic or a static IP. It also differs if you are dialup (ppp - modem connection) or dsl (eth0 -NIC connection). Can you fill us in plz?

ifconfig <device> down
ifconfig <device> up

Where <device> is usually...
eth0 (or eth1, eth2, etc... depending on how you assign your NIC) for NICs

I don't think you're using dialup/modem, correct me if I'm wrong.

Are you doing this as root? Is /sbin in your path? You can always try "/sbin/ifconif" to explicitly state the path. It is in the rpm net-tools: you can always do "rpm -q net-tools" to make sure you have it, but I suspect you do.

The configuration information is actually in a file called /etc/network-scripts/ifcfg-eth0. It is worth taking a look at even if your configuration is setup properly already through a GUI. I myself explicitly set my IP (local 192.168.0.0 space) there, although most people use the DHCP from their router/modem.

The "ifdown eth0;ifup eth0" sequence should work if your NIC is configured as eth0 (which it usually is). Basically, the /etc/init.d/network script does on bootup is an "ifup eth0" (getting this from the existence of a file /etc/sysconfig/network-scripts/ifcfg-eth0). I suspect your routing was messed up as well. I would do the following next time (as root, of course) "/etc/init.d/network restart" . This would reset all network parameters and devices to bootup conditions. You can mess around with it if you like. For example, save the output of "/sbin/route" and "/sbin/ifconfig". Execute "/etc/init.d/network stop" and you will nolonger have internet. Compare the output "/sbin/route" and "/sbin/ifconfig". now to the previous output. The execute "/etc/init.d/network start" and see that the output of those commands are now what they were to begin with. Note: "/etc/init.d/network restart" is simply a stop/start in sequence. Have fun.
