chklastlog - check lastlog-file for deleted entries
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.
