check-permissions

check-permissions(1M)					  System Administration Commands				     check-permissions(1M)

NAME

       check-permissions - check permissions on mail rerouting files

SYNOPSIS

       /usr/sbin/check-permissions [login]

DESCRIPTION

       The   check-permissions script is intended as a migration aid for sendmail(1M). It checks the /etc/mail/sendmail.cf file for all configured
       alias files, and checks the alias files for :include: files. It also checks for certain .forward files. For each file  that   check-permis-
       sions checks, it verifies that none of the parent directories are group- or world-writable. If any directories are overly permissive, it is
       reported. Otherwise it reports that no unsafe directories were found.

       As to which .forward files are checked, it depends on the arguments included on the command line. If no	argument  is  given,  the  current
       user's home directory is checked for the presence of a  .forward file. If any arguments are given, they are assumed to be valid logins, and
       the home directory of each one is checked.

       If the special argument ALL is given,  the passwd entry in the  /etc/nsswitch.conf file is checked, and all password entries  that  can	be
       obtained through the switch file are checked. In large domains, this can be time-consuming.

OPERANDS

       The following operands are supported:

       login	       Where login is a valid user name, checks the home directory for	login.

       ALL	       Checks the home directory of  all users.

FILES

       /etc/mail/sendmail.cf   Defines enviornment for	sendmail

       /etc/mail/aliases       Ascii mail aliases file
