# This is a simple script to compare the currently installed version of samba to the latest stable release
# available via the www.samba.org website.  If the versions do not match, the script will email you.  Schedule
# this script via cron to run weekly for best results.

# Instructions:

# Replace <from_address> and <to_address> with sender and recipient emails below (without the brackets).

# Prerequisites:

# This script requires the mailx package in order to send notification emails.

# NOTE: This script was developed on a CentOS 7 64-bit system.  It may require modification to work on other
# Linux distributions or architectures.
