chkwtmp


SYNOPSIS
       chkwtmp

DESCRIPTION
       Chkwtmp examines the file /var/log/wtmp for entries with no information
       (containing only null-bytes). If such entries  are  found  the  program
       prints the time window for the original entry. This is done by display-
       ing the timestamps of the  wtmp-entry  before  and  after  the  deleted
       entry.

       To  run  chkwtmp  you  need  read permission on the file /var/log/wtmp.
       Normally this file is world-readable  and  no  special  privileges  are
       required to run the checker.

FILES
       /var/log/wtmp       login data base

SEE ALSO

LIMITATIONS
       An  entry is recognized as overwritten if the time-information has been
       overwritten with null-bytes.

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