NAME
mailer - script to warn users about their weak passwords SYNOPSIS
mailer password-files DESCRIPTION
This manual page documents briefly the mailer command, which is part of the john package. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. john, better known as John the Ripper, is a tool to find weak passwords of users in a server. The mailer tool is useful to inform users which have been found to be using weak passwords by mail. You should edit the message mailer will send to the users, but remember to copy the script to a safe place before editing it, as it's gen- erally a bad idea to modify things living in /usr. SEE ALSO
john(8), unafs(8), unique(8), unshadow(8). The programs are documented fully by John's documentation, which should be available in /usr/share/doc/john or other location, depending on your system. AUTHOR
This manual page was written by Jordi Mallach <jordi@debian.org>, for the Debian GNU/Linux system (but may be used by others). John the Ripper and mailer were written by Solar Designer <solar@openwall.com>. The complete list of contributors can be found in the CRED- ITS file in the documentation directory. john June 03, 2004 MAILER(8)
