I like tcpdump. I save the output to a file and view the file on my
linux (or windows) box with ethereal/wireshark.

Or you could either find an AIX Wireshark binary, or build it
yourself ...

I haven't built Ethereal on AIX in several years, but don't recall it
as having being very difficult.

Thanks for the replies.

Is there a good howto to use tcpdump on AIX? I am trying to capture
all NFS packets from one server to another and troubleshoot a NFS
failure.

thanks

FWIW
I have EtherReal (now WireShark) installed on my PC...
I use IPTRACE on AIX to capture the information, then FTP it
to my PC for display in EtherReal.

Regarding HOWTO:
iptrace -a -b -s source_host -d dest_host my_capture_filename

Assuming I am capturing on source_host, the above command will capture
all interactions between source_host and dest_host...
If you want to limit the capture to just a single PORT, then add "-p
portnbr" to the command
line. For example to capure only http network traffic:
iptrace -a -p 80 my_http_capture_file
