snoop on Tru64?

Is there anything similar to snoop on Tru64?

Tcpdump runs on just about every Unix variant there is, so I would expect
it to have been ported to Tru64 as well.

There's tcpdump which comes as part of the Additional Networking Services
subset. It's a little tricky to set up for the first time. You need the
packetfilter option compiled into the kernel (see man packetfilter)
and then need to use:

ifconfig [interface] promisc - to set your NIC to promiscous
pfconfig +p [interface] - to set the packetfilter to promiscous and
pfconfig +c [interface] - to set it to copyall mode.

Regards,

Andrew

There is little reason to select anything save "all of the above"
when compiling the kernel on an ALPHA. If an admin neglected to do
that at boot time, it is a simple matter to run "doconfig" (after
booting the generic kernel) and do it at any time after. Compiling
everything into the kernel at install time (or during some scheduled
downtime) eliminates the need for reboots and downtime when later
installing options that involve kernel support.

Hope this helps,
Don
