Re: Single NIC multiple configurations

Michael Griffin wrote:

I have a laptop with a single NIC which I use for both work and home. Obviously my network settings are different but I was wondering if I
could set it up so that the correct configuration would come up
depending upon which environment I was in.  I am not opposed to manually
bringing the network up or down in each, setting, I am just wondering
what would be a "best practice".

I was/am considering using aliasing (eth0:0, eth0:1), but I am not sure
how I would go about it.

All responses appreciated,

Thank you,


Use multiple network profiles as configured via system-config-network on FC2 or redhat-config-network on FC1. I.E. create a home profile and a work profile and put different named inteface configurations that may use the same device (eth0) in, and have one active in home profile, and one active in work profile. Edit /boot/grub/grub.conf duplicating the entire entry for your preferred boot choice, then add "netprofile=home" to the kernel line on one, and "netprofile=work" to the other. Hint: you can add "home" to the end of one title line and "work" to the end of the other title line so it is easy to tell which you are choosing in the grub boot menu at next boot.

Here is a sample boot entry for a "home" network profile:
title Fedora Core (2.6.3-2.1.240) home
       root (hd0,0)
kernel /vmlinuz-2.6.3-2.1.240 ro root=LABEL=/ hdc=ide-cd vga=792 acpi=on psmouse.proto=imps netprofile=home
       initrd /initrd-2.6.3-2.1.240.img
