Changing Server IP

**jimbaloo** · 10-20-2005

I have to change the IP address on a friends server tomorrow and I was hoping to get a few pointers from those of you more knowledgeable than I. The machine is running Fedora Core 2, and the service provider has changed and given them a new IP address, that has to be set tomorrow.
Thanks for the advice.

rehdat-config-network or edit /etc/sysconfig/network-scripts/ifcg-eth0.

I just looked at this on my own box and got this:
DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:10:5A:14:43:53
ONBOOT=yes
TYPE=Ethernet
DHCP_HOSTNAME=spottydog.doghouse.com
What parts in this need changed?

[edit]This might make sound stupid but can I just do ifconfig eth0 0.0.0.0 netmask 255.255.255.255 where 0.0.0.0 is the IP address?

You could just do "ifconfig eth0 IP up".

You can do that, but by far the easiest way is to use the redhat tool for network config. It works from both command line and from X - and it's actually called:

system-config-network

on FC2

Thanks for the advice guys, I really appreciate it.

Unfortunately the new service provider didn't provide updated DNS addresses, and the physical wiring on the server was a mess so they had to call in a professional.
At least I learned something from the experience.
