Chaneg ip addr in RedHat AS3

franlo — Mon, 03 Jul 2006 10:46:53 GMT

Hello,

I'm new on Linux,
Could you tell me how to change (in command line) the ip address on redhat AS4 ?

No netconf file and net startup script found ;-)

ifconfig tell me 3 nic with all the same address (eth0, eth1 and bond0) and all of then have the same mac adrress. what does it mean ?

Sure it's a basic question but i'hadn't found aswer in admin guid (only gui way).

Thanks a lot

Regards

Francois

The file is:

/etc/sysconfig/network-scripts/ifcfg-eth0

Change the line:

IPADDR

The run:

ifdown eth0
ifup eth0

Shalom,

Suggestion for testing. cp the ifcfg-eth0 file to /root so if you make mistake you can recover.

You can try out your ideas or change temporarily with the ifconfig command, which works the same as HP-UX.

The GATEWAY for the NIC can be in the ifcfg-eth0 or /etc/sysconfig/network

Hello all,

Thanks a lot for your answers.

ifconfig is alright for me but i was lokking for configuration files. I read in man that /etc/sysconfig/network 's files are not editable, but in fact it's ok to change those.

I saw after that bound0 is for agregate nic, that's why i have same mac address.

thanks a lot

That would be bond0

In this case you don't want to change eth0 and eth1 because they are slaves to the software bond ethernet driver bond0

You change the ip address with the ifconfig command to bond0 instead of eth0 and change the file /etc/sysconfig/network-scripts/ifcfg-bond0
