       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
       cfingerd  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 (

       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.  :)


       -c     Give standard CFINGERD (custom) output.

       -n     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
       file.  If 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 world-readable.)


       If you like this program, have any  suggestions  on  how  it  could  be
       modified, or have bug reports, please write to:
