Or, if you have a 2.4.x kernel:
# apt-get install iproute2
# ip addr add 10.0.0.2/16 brd + dev eth0 # same as example above
# ip addr add 192.168.0.2 dev eth0 # use this for an address on \
the same subnet as the "primary" address
As far as where each application sends its data from, you'll have to
either configure each app to bind to the appropriate address, or use
iptables to mangle packets based on source port.
