how to add an ip alias in opensuse?

[karozans]

Hi.

How does one add an ip alias to an eth device using the ip command instead of the ifconfig command?

I do not want the alias to be permanet.

man ip

ip addr { add | del } IFADDR dev STRING

when I run

ip addr add 192.168.1.5 dev eth0:0

The IP address is indeed added. But it is not added in the form eth0:0

Does this matter?

When I add a address alias through yast2 in opensuse, I see that the alias is added as eth0:0.

You need to modify your ip command just a bit:

ip addr add 192.168.1.5 dev eth0 label eth0:0

Then verify it, e.g.:

[root@host] ip addr show dev eth0
2: eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether 00:11:22:33:aa:bb brd ff:ff:ff:ff:ff:ff
    inet 10.1.1.4/24 brd 192.168.1.255 scope global eth0
    inet 192.169.1.5/32 scope global eth0:0
