I was previously running a home network (three computers) with Windows. I am trying to move to Linux. In configuring the network, I need to tell Linux what the numbers (such as 192.168.0.5) are for the different computers. It tells me that if I do not know such stuff, then I should contact my Network Administrator. Trouble is, I are him. :-( Probably what I need is to be pointed to a good howto or tutorial on this. (Along the lines of teaching me how to fish, rather than just giving me one.)

Thanks for any help.
John (a newbie, but coming along)

ip-address is set when you set up your ethernet-card, with commands such as ifconfig and after it, route. other ips and their hostnames are set in /etc/hosts..like

ifconfig eth0 192.168.1.1 netmask 255.255.255.0 up
route add ...etc...etc...etc...

that's a start. use google to find more stuff on how to get your network up and running, or read the man for route and ifconfig.

So long as each PC has a different IP, they can be anything within the 192.168.0.xxx range.

It would be useful to know exactly what your setup is, are you using a router? If so, the router IP needs to go in the "gateway" setting for each of the PCs. The "Subnet mask" should be set to 255.255.255.0 and DNS server is usually fine set to your router's IP.

Since you're on RH you probably want to use
their wizards to make those changes permanent.

Try something like
system-config-network from a command-line, or
locate the network wizard in the Gnome GUI.

About the kind of addresses that you use: That
heavily depends on what network gear you're
using, if you, for example, happen to have an
ADSL router it may well be that it hands out
IPs to your machines via DHCP, in which case
you just need to chose DHCP in the network
setup tool. If they are manually set-up you can
basically chose random IP addresses in the
192.168.x.y range as long as you make sure
that all machines have the same x and different
y (and both of x and y are 0 < n < 255 ...
