Re: login can be used to hide from finger under SunOS 4.13u1

Login will hide you from finger, but it does not remove you from being seen
through "w" or "who"...  When you "login" after you have logged-in, you
overwrite your current tty with a new one, therefore removing the original
location through which you came into the system.
