NAME

       chklastlog - check lastlog-file for deleted entries

SYNOPSIS

       chklastlog

DESCRIPTION

       Chklastlog  is  reading  all entries from the file /var/log/wtmp (file with informations about logins and
       logouts) and checks for  every  user  found  in  this  file  whether  there  is  an  entry  in  the  file
       /var/log/lastlog, too. The program will complain about userids with logins but no lastlogin information.

       To  run  chklastlog  you need read permission on the files /var/log/wtmp and /var/log/lastlogin. Normally
       these files are world-readable and no special privileges are required to run the checker.

FILES

       /var/log/wtmp       login data base
       /var/log/lastlog    last login times

LIMITATIONS

       This program only works if the user has not logged in after the deletion of their lastlog entry.

       This program was designed to run on SunOS 4.x systems only. On other systems the output is undefined...
