network configuration

Trent Bukowsky — Mon, 15 Oct 2001 02:14:05 GMT

I finally have my Linux box up and running. But I want to switch IP addresses on a regular basis.

I have only one Ether card and I have to switch between Internet and intranet IP's. I know how to change IP's using netcfg. But what I would like to know is how can I do it from the "#" prompt without GUI. WHich files should be changed and what are the commands I have to run along with syntax.

If somebody can tell me it would be most helpfull. It would also be helpful if somebody can tell me how to change IP's on an OPENBSD machine.

Thankx

Hi

If you are using RedHat (or similar) distribution, your network configuration is stored under
/etc/sysconfig.
See /etc/sysconfig/network and /etc/sysconfig/network-script/ifcfg-eth0

and /etc/hosts, /etc/resolv.conf are also important.

(Again on redhat systems) Alternatively, run the /sbin/netconf script with will set all the necessary files based on your responses. This program runs in a screen oriented GUI if X is not up.

The IP information for network interfaces on OpenBSD are stored in the /etc/hostname.* -files.

Run 'man hostname.if' and 'man afterboot' for instructions.

You could also try to bind two IP addresses to one card.
(Aliases) that way, when you switch the cable, it should work automaticly.
It is not a clean solution, but a laisy one :)
