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. -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing: domain: grr@cbmvax.commodore.com Commodore, Engineering Department phone: 215-431-9349 (only by moonlite)
