Pix "capture" does not show live traffics like

Checkpoint tcpdump or fw monitor. you have

to use "show capture xxx" to view traffics.

By the time you see it, it is not live anymore.

tcpdump and "fw monitor" show you actual

live traffics on the interface.

A PIX doesn't have tcpdump nor fw monitor. This is a PIX not a Checkpoint.

The original poster asked "How to see the live traffic on the PIX interfaces."

capture does not have the ability to let users

look at live traffics. That's my point.

hello sukh,

connect the pix inside interface through a switch, and do port mirroring on the switch to capture all traffic flowing through that pix.. use the SPAN feature of the switch to mirror the port.. as others said, there are no inbuilt command or feature in PIX, to do this functionality...

Hope this helps.. all the best..

A couple of things I do with either PIX or ASA to watch live traffic:

1-Syslog, just be sure to have a syslog server (easier to sift through) and log to informational level.

2-Can look at output from show conn (not as helpful but you can grep or | inc for specific ip's. This is more of a sanity type of check.

What version of code are you running? The ASDM is useful unless you are wanting to see more than just syslog type of traffic.
