Objet : [SLE] one network-card with 2 different configurations
Hi
In my office I need to define a fix IP address for the network-card, but
at home everythink works with DHCP.
since I don't feel like everytime I change to the office or come home to
newly define the network card with yast:
Is there a possibility to define one and the same network-card with two
different 'profiles' so that I just need to switch the profile ( I think
this exists for mac's ...)
many thanks for your kind help
I am sure, there must be many users, facing the same problem
cheers

I've met the same problem with my nvidia card, I wanted to boot
either with TVout support or not. Isolved it by defining an
environment variable at boot, according to the value I choose by a symbolic
link between two different XF86Config files.

In your case you can define either the "office=" or the "home=' as boot
parameter
and in one case link to a ifcfg-eth-id-xxxxxx file and in the other case to
another file.

You define an init script in /etc/init.d which is run before starting
network and it'll work.

As example you'll find below the script I wrote for xfree.

Ready to explain more and to help you.
