As of release 4.2, Ultrix includes a version of tcpdump in the unsupported
subsets.  This is probably similar to what your Ether_listen does.  It is
possible to run tcpdump on earlier 4.x versions, but there are compromises
involved.  Note that Sun workstations also include a similar program called
etherfind and there is a version of tcpdump that work there also.  If is
often advantageous to have a "third party" doing the monitoring, not one of
the host systems.
