Note, there is a problem with using tcpdump and Ultrix 4.1 if you are using
LAT. To run tcpdump usefully you have to put the interface into promiscuous
mode, this results in lat not working on any other system on the ethernet,
presumably because the ultix system is now replying as well. The problem
doesn't go away until you reboot the ultrix system.
