[TriLUG] How to set a persistent route in Linux

[Jason Faulkner]

(hey, I learned this this week! huzzah!)

in debian, just put a script in /etc/network/if-up.d that pulls them
up. Something basic like

#!/bin/sh
route add -net 192.168.2.0 netmask 255.255.255.0 gw 192.168.1.2 dev eth0

and it automagically runs it when you bring networking up. BRILLIANT!
