Logcheck is a program that automatically monitors your system logfiles on a regular basis and emails security violations to you. It looks for messages generated by various programs (including Portsentry and Hostsentry) that indicate a hacking attempt, and generates a report which is emailed to the chosen address.

The options on this page are :

- Email reports to
  The email address to which security violation reports and sent.

- Hacking log messages
  A list of messages which if found in one of the system log files indicate a hacking attempt.

- Violation log messages
  A list of messages that indicate a potential security violation. Any message that is on this list but also in the 'Except for' list below it will be ignored.

- Ignored log messages
  Any log message listed in this field will always be ignored, even if it matches one of the hacking or violation message strings.

At the bottom of the page is a form for choosing exactly when Logcheck should be run. However, if your Logcheck install uses a Cron script that forces it to be run hourly or daily, this form will not be displayed.
