UNSHADOW(8) System Manager's Manual UNSHADOW(8)NAME
unshadow - combines passwd and shadow files
SYNOPSIS
unshadow password-file shadow-file
DESCRIPTION
This manual page documents briefly the unshadow 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 unshadow tool combines the passwd and shadow files so John can use them. You might need this since if you only used your shadow file,
the GECOS information wouldn't be used by the "single crack" mode, and also you wouldn't be able to use the '-shells' option. On a normal
system you'll need to run unshadow as root to be able to read the shadow file.
SEE ALSO john(8), mailer(8), unafs(8), unique(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.

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.
