The original login still shows up in the wtmp file though.  And I can find
out where (what IP address) you are coming in from by doing a 'netstat -na'.

Doing a 'login username' from the C shell can occassionally be useful,
especially if you are using someone else's workstation or X terminal
and just want to start up a new xterm and login as yourself (yeah I
know you can 'su' or 'telnet localhost'!).
