Login session conected from network.
>Description:
When called from user prompt login(1) clears utmp entry,
removing info about user location in network. It's still
possible to find the original conection from netstat and
fstat, but it's not easy.
>How-To-Repeat:
telnet to somehost
$w
See FROM field
$login
Enter user and password
$w
See new FROM field: no network address
>Fix:
I'm not sure, but maybe a previous check in utmp could help.
Don't know which side-effects it could have on normal logins.
