Re: A source of martians?

Hi Capt_Caveman
Hello, welcome to Linuxquestions.

My question is this: Can martians be caused by the fact that Linux Server eth1: is receiving broadcast data intended for the 192.168.0.x network?In the same breath, can martians be caused by the fact that the Linux Server eth0: is receiving broadcast data intended for the 192.168.1.x network (the network that the Router and Linux Server eth1 are on)?

I believe so. You'll often see martians anytime you have two NICs with different networks on the same physical layer. In this case the switch should keep the networks reasonably seperate, but broadcast traffic is probably still getting through and causing the problem (specifically broadcasts with a source IP of 192.168.0.X showing up on the interface and vice-versa). That's a guess, so I'd need to see some packets or the martian log messages to be any more sure. I think this is a situation where you could physically rearrange your network topolgy in order to solve the problem.

Talking Thanks...

Thanks for the reply. I kind of thought that would be a cause of martians. I've been doing a lot of reading up on them-- it's not every day martians make contact with me!
