CHKLASTLOG(1)
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
SEE ALSO
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...
