userlist - Userlisting of who's on your system.
This program simply gives you a listing of who is connected to your system. It
is used primarily in the sorted listing of cfingerd
, which utilitizes
the same method of display for a more uniform output between systems. (It also
made more sense to do it this way instead of having jumbled up display
listings in sorted finger displays. Besides, it made more sense to do this
than use finger. :)
This program functions with the same types of things in mind that
does. If the user has a .nofinger
file, their username
will not be displayed in the userlisting.
Example output is shown as:
Username Real Name Idletime TTY Remote console
username I'm real ... 9d 23:59 0 (remote.site.com)
where it would display the user's login name, the user's real name, their idle
time given in the format "dd hh:mm", their TTY, and their remote
location (or where they're telnetting from).
If the username is over 8 characters, the program will not search for their
information in the passwd file, since it may be too long. Besides, it checks
getpwnam, anyway. :)
- Give standard CFINGERD (custom) output.
- List only people idle less than one day.
Although userlist is not required to run as suid root, it is a good idea. The
reason is it checks each users' directory for a .nofinger
indeed that user has a .nofinger
file in his/her directory, that user
will not be shown in the userlisting.
If you change the program to run as nobody.nobody, you are free to do so. But
you will also show the users if they are online, regardless of whether or not
they have a ".nofinger" file (as long as their directory is NOT
