Berkeley Network

   (B-NET) Top level {Unix} {Ethernet} software developed at the
   {University of California at Berkeley}.  There are no formal
   specifications but UCB's {4.2BSD} {Unix} implementation on the
   {VAX} is the de facto standard.  Distributed by {Unisoft}.
   Includes net.o driver routines for specific hardware, {pseudo
   ttys}, {daemons}, hostname command to set/get name, /etc/hosts
   database of names and {Internet address}es of other hosts,
   /etc/hosts.equiv host-wide database to control remote access,
   .rhosts per user version of hosts.equiv.

   UCB's implementation of the {Internet Protocol} includes
   trailers to improve performance on paged memory management
   systems such as {VAXen}.  These trailers are an exception to
   the Internet Protocol specification.
