[Giving Donald a short break]

The command "ifup eth0" assumes that you have eth0 somehow "configured" on
your system.  If you're a RedHat user, that configuration is in
/etc/sysconfig/network-scripts/ifcfg-eth0, and will look something like


Hopefully, this is all pretty self-explanatory.  Most distros have something
similar.  Suse sets this stuff in its big rc script, for example.  But
almost all distros have a way (linuxconf, yast, etc.) to add and manage the
interface via a tool which is presumably easier than hand-editing the config

At any rate, if you type "ifup eth0" and it returned a usage, it's because
it didn't find the configuration information for eth0.  On to ifconfig....

ifconfig is used to configure your network interfaces, which includes
assigning an ip, and network mask, broadcast address, etc.

Donald used because it's a safe IP address to use.  You need to
replace that with whatever the correct IP address for this machine is.  If
the network is working under Windows, then boot into Windows, open the Start
menu, choose "Run...", type "winipcfg" in the box that comes up and press
"enter".  You'll be greeted with a dialog that shows the information for
each network interface, choose your network card and press the "More info>>"
button.  You can see there what the IP Address is.  If you're using DHCP to
obtain that address (i.e. "DHCP Server", "Lease Obtained", and "Lease
Expires" are populated) then you'll have to set up DHCP on the Linux side,
and I don't even want to go there.

The simple fact is this: if you can use "ifconfig" to start the interface,
then it's working.  You just need to configure the system to know about it.

Yes, you need to learn how to set it up.  Try "linuxconf", if that doesn't
work, try "yast".  Not sure what is used in Debian.  You'll have to poke
around a bit.

Hope this all helps.
