[Xymon] old hosts.cfg tag "login"

Big Brother used to match service names in BBNETSVCS (defined in bbdef-server.sh), and lookup the port number in /etc/services, and try to connect with bbnet to the TCP port.  The "login" service is more commonly called rlogin and operates on TCP port 513.  Nobody uses it anymore.  If you have an old bbdef-server.sh and if BBNETSVCS includes "login" then this is likely to be it.

If the servers are still using rlogin, and you can't have it turned off, and you still need to test for it, you can emulate the same test by adding an entry to protocols.cfg.
