Title: 2 IP's on the same NIC
Post by: Craig on February 21, 2002, 06:59:55 PM

I have 1 NIC in my SME v5.1.2 and I would like to setup an alias IP address on that same NIC.

ie: on the same NIC I would like to have 111.111.111.111 and an alias IP of 222.222.222.222

I have done this before with RedHat using Webmin but I am not sure how to achieve this with SME.

Thanks in andvance for any help.

Regards
Craig

Craig

Use 'ifconfig' to setup a virtual IP.

ie. 'ifconfig eth0:0 222.222.222.222 netmask 255.255.255.0 up'

This should do what you want.

David

Thanks for the info

If the server gets rebooted will it loose this setting?
If it does loose this setting on a reboot I could put it in rc.local?

Hi Craig

Yes it will loose the setting if rebooted, I assume you can put it in rc.local as this is the last script to be run at boot up.

SME is still RedHat under the covering.  If you create /etc/sysconfig/network-scripts/ifcfg-eth0:0 with the same contents RedHat would use for an IP alias, SME will initialize the same way at startup and the ifup, ifdown scripts will work.
