assigning ip address after install
 

where can i change the ip address of my rh7.2 box after installation? also, if i selected dhcp at the install stage, do i need to change this for the change in ip address to take effect?

you can edit the file /etc/sysconfig/network-scripts/ifcfg-eth0
or you can type in setup at the command line and select network configuration.

run the '/usr/sbin/netconfig' program. This a simple ncurses program. There you can change from DHCP to STATIC and also modify your IP info.

'/usr/sbin/redhat-config-network' is a flashy gui that I think does the same thing and more. If you're curious, check out the other redhat-config-* programs in /usr/sbin.

For network changes to take place, all you need to do is to 'take down ' the interface and bring it up again. If you have only one interface and its a ethernet card, then it's usually called 'eth0'. So you can do 'ifdown eth0' or the more standard 'ifconfig eth0 down', then 'ifup eth0' or 'ifconfig eth0 up'.
