Hi guys,

I'm running CentOS 4.4

I know how to add an IP address (aliased to eth0, such as eth0:1) via the GUI based system-config-network

But how is this done via SSH only? Using system-config-network-tui, I only see an option to configure the Ethernet, I tried just changing all the settings to:

Name: eth0:1
Device: eth0
Static IP: the new IP
..etc

(hoping that it would still keep my eth0 config and simply add eth0:1, but I don't really know what I'm doing here..)

but that didn't seem to take effect (ifconfig didn't show the new IP on eth0:1)

I did:

service network restart

and still no show. Is that the right way to add an IP alias to the network card via SSH, or maybe I'm not restarting the network properly?


Thanks
Nat

Post output from ifconfig -a

Thanks Brian,

Let me make sure I understand, I have these ifcfg* files under /etc/sysconfig/network-scripts/

-rw-r--r-- 3 root root 188 Feb 20 09:14 ifcfg-eth0
-rw-r--r-- 1 root root 254 Jun 20 2001 ifcfg-lo


This is what is in my ifcfg-eth0 file:

[root@server ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0:1
BOOTPROTO=none
BROADCAST=192.168.1.255
HWADDR=00:11:2f:71:54:d0
IPADDR=192.168.1.111
NETMASK=255.255.255.0
NETWORK=192.168.1.0
TYPE=Ethernet
GATEWAY=192.168.1.1
ONPARENT=yes



If I wanted to add say 192.169.1.112 to my box, would I add another entry in this *same* file (ifcfg-eth0) and list the device as eth0:2 ?


I only have on NIC card in the box.


Thanks

No it will be a seperate file. Look at this site for detail look of files and their contents. http://www.ducea.com/2006/07/15/linu...based-systems/

What you have it your current ifcfg-eth0 does not look right at all. Check this for a reference.

in the past i've been caught out by some scripts not liking the : in the file name. the name of the file is probably easier delt with as ifcfg-eth0_1 for example. just a tip that may be irrelevant these days.
