The regular expressions below are proposed failregex for this software. Multiple regular expressions for failregex will only work with a version of Fail2ban greater than or equal to 0.7.6.

The tag <HOST> in the regular expressions below is just an alias for (?:::f{4,6}:)?(?P<host>\S+). The replacement is done automatically by Fail2ban when adding the regular expression. At the moment, exactly one named group host or <HOST> tag must be present in each regular expression.

Please, before editing this section, propose your changes in the discussion page first.

  • vsftpd: .* authentication failure; .* rhost=<HOST>$
  • \[.+\] FAIL LOGIN: Client "<HOST>"$
