At least one workstation vendor shipping SVR3 with 4.3BSD-tahoe TCP/IP has
extended the SV fuser command for just this purpose.  A "path" of the form
'port/protocol' or 'hostname:port:protocol' which does specify a valid file
is understood to be a request to list processes with the sockets connected
to the specified port.  'Port' must be an integer constant, and 'protocol'
must be either TCP or UDP.  'Hostname' must be a IP number or hostname, and
is used to specify individual connections.
