Here I am replying to my own message.  I should have added that when the
initial vic tool comes up, it has not "followed" the display machine to
the initial venue -- i.e., the "address," "port," and "ttl" boxes are all
empty.  I can manually enter the address/port/ttl into these boxes and the
captures start (I noticed I can also enter the display machine's IP and
the port 10001 and a capture starts???).

Any insight would be welcome.
