ifconfig

(as root) Display info on the network interfaces currently active (ethernet, ppp, etc). Your first

ethernet should show up as eth0, second as eth1, etc, first ppp over modem as ppp0, second as

ppp1, etc. The "lo" is the "loopback only" interface which should be always active. Use the

options (see ifconfig --help) to configure the interfaces.

ifup interface_name

(/sbin/ifup to it run as a user) Startup a network interface. E.g.:

ifup eth0

ifup ppp0

Users can start up or shutdown the ppp interface only when the right permission was checked

during the ppp setup (using

netconf ). To start a ppp interface (dial-up connection), I normally

use kppp available under kde menu "internet".

ifdown interface_name

(/sbin/ifdown to run it as a user). Shut down the network interface. E.g.: ifdown ppp0 Also,

see the previous command.

netstat | more

Displays a lot (too much?) information on the status of your network.
