Re: Combining ethernet devices for sniffing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Ed,

There are 4 interfaces:

eth0 -> transport
eth1 -> unused
eth2 -> sniff
eth3 -> sniff

eth2,3 are plugged into a fiber tap and each card carries 1 direction of the bidirectional traffic.

I would like to combine them to form a single interface for things like tcpdump, tethereal, snort, etc. I don't want eth0,1 to be a part of it.

Thanks,
Harry

Exactly what is the task?

If it is simply to capture traffic on all interfaces is there any issue with using tcpdump with the "-i any" parameter?
