Via Wabi

Greetings -

I'm attempting to bring up CU-SeeMe (latest PC version)
running under Wabi 2.1 on Solaris 2.4. CU-SeeMe launches
and allows me to select a site to connect to. A snoop
shows that the server side is rejecting the request
due to "bad port" (See appended short trace).

Others on this alias have reported CU-SeeMe working w/
Wabi. I'm curious as to which versions of the app and of
Wabi were used. It would also be helpful to know why my
connection request was being rejected.

Thanks -
