Multiple IPs

[Lawrence MacIntyre]

Ben:

I'm not too good at GUI interfaces either, but here's how to edit the
config files...

Here is an example of the /etc/network/interfaces file with one address
on the eth0 card being assigned by dhcp and another assigned statically.

auto eth0
iface eth0 inet dhcp

auto eth0:0
iface eth0:0 inet static
  address 192.168.0.1
  netmask 255.255.255.0

eth0 is the primary (real) address, and eth0:0 is an alias (the one you
want to add).  Modify this file, substituting your preferred address and
execute the command:

/etc/init.d/networking restart

Note that you can just use DNS aliases and keep the same ip address if
you want to.  The only real exception is when you want to use SSL
certificates, as they work best when the name matches the certificate.
