Angry Red Hat 7.2 configuration


Please advise

I am a new user to redhat 7.2

Does anyone know how to add a second ip number to a Network interface card or know of a HOW TO paper. Am I right in thinking it has something to do with aliases.

Any suggestions.

Thanks

Burchy

i don't think a second ip to one device is possible.. if you had two ethernet cards its possible.

What you wanna do it's quite easy. Just follow these steps:

- create a file named ifcfg-eth0:1 in your /etc/sysconfig/network-scripts directory;
- write this in that file:

DEVICE=eth0:1
ONBOOT=yes
BOOTPROTO=static
# here you should make some adjustments
IPADDR=192.168.1.1
# here too
NETMASK=255.255.255.224
# and here
GATEWAY=192.168.1.1

- restart your network service

Ok, you're up and runnin'...

Good luck.

Thumbs up YUP!!

Ionut, You beat me to it. I've put 3 IP's on one single interface. Pretty kewl! If you think that is impressive, I know someone that has configured 1 interface to do dhcp (ppoe), gave it an internal IP address, AND HAD ALL His PC's on his LAN to go out that interface to the ethernet. A lot of collisions but hey it works.

This is not impressive, but common. I am using this "alias" tehnique for virtual hosting (www, mail and ftp). Look what an ipconfig shows at my console:
