The -h flag is an undocumented flag to login that is used to pass host
info through to the utmp record.

The reason for these are that login is a built-in command in most
(all?) shells.  The built-in command takes at most one argument, a
username; thus, "login -h tip.address" is too many arguments and "login
-h" tries to log you in as the (probably nonexistent) user named -h.
You need to run the login *program*.  Try using /bin/login instead of
just login.  (Note, if you do this then when you log out you will
likely find yourself back in your original shell; to avoid this use
"exec /bin/login" or some such.)
