I have a machine on which I need to use both wired (eth o)and wireless interface (eth1). I essentially need that it should first try with wired itnerface to get routes to the LAN and then use wireless interface for wireless devices.

How can I do this?

Are both interfaces on teh same IP range?

If not it's easy - make the default gateway the router on the wired IP range, make a secondary default gateway on the wireless IP range.

If they're on the same network, a little trickier, but note you can still add routes to the table which *specify* which local adapter to go via, e.g.
(from the Man Route pages!)

route add -net netmask dev eth0

That "dev eth0" bit says "route this traffic out of the box via eth0" even if other adapters are available which acn also reach the network in question.
