listening on multiple interfaces

[Jeff Wolfe]

Hi Folks,

I've gotten used to argus' ability to listen on multiple ports on the same 
machine. (we use the Shomiti Century taps which have 2 outputs, one for TX and 
one for RX.) 
Is anyone aware of a tool that can write tcpdump formatted output files but 
capture from two interfaces simultaneously? Failing that, I guess I could use 
or write a tool to multiplex two seperate tcpdump streams together..

Any ideas?

I need to capture some streams for analysis and the only format my tools 
understand is tcpdump capture files.

Thanks..
