two network interfaces don't get along

nurey

I have a wired ethernet eth0 and a wireless eth1 via pcmcia

This is gonna be complicated to explain so please hang with me...

The problem is that when i unplug the cat5 on eth0 and activate eth1, both eth0 and eth1 are "UP" and this somehow confuses eth1 such that I cannot ping the eth1 gateway, until I do "/etc/init.d/net.eth0 stop"

This causes another problem. When i stop net.eth0, all services that depend on it also stop (eg. postfix). I don't want this to happen. I want the dependent services to keep running.

I notice that the postfix rc script contains depend section with "need net"... so shouldn't it keep running given that net.eth1 is UP?

Did you copy net.eth0 to net.eth1 and use it to handle your second interface?

Could it be that both interfaces believe they are the default gateway? Sounds like a routing conflict to me.
