Today's discovery is that if you're foolish enough to enable DHCP on an alternate network interface (eth3, in my case) on Linux, then the DHCP client will overwrite your hand-configured default route that actually works with the one it received from the DHCP server.

Which is not particularly helpful when eth3 is connected to a different LAN with a router that actually checks the IP addresses of packets it forwards. At which point it eats the SSH connection I was using (because that was to an IP address on eth0) and I had to wander down to the lab and dig out a keyboard and monitor.

I am becoming more and more convinced that the Linux network stack just Does Not Work as soon as you plug it into more than one network.
