MRTG or The Multi Router Traffic Grapher can be used to monitor SNMP network devices and displays the traffic that has passed through each interface.

Log in to your server as root.

First you should create a folder to store mrtg graphs/html pages
# mkdir -p /var/www/html/mymrtg/

Use cfgmaker command to create mrtg configuration file
# cfgmaker --global 'WorkDir: /var/www/html/mymrtg' --output /etc/mrtg/mymrtg.cfg public@localhost

Now you should create default index page for your MRTG configuration
# indexmaker --output=/var/www/html/mymrtg/index.html /etc/mrtg/mymrtg.cfg

Copy all tiny png files to your mrtg path
# cp -av /var/www/html/mrtg/*.png /var/www/html/mymrtg/

Now test if MRTG is running fine:

(a) Run mrtg command from command line with your configuration file:

Run this command
# mrtg /etc/mrtg/mymrtg.cfg

You may get few warning message for first time, thats ok, ignore them.

Check the next url:

http://www.yourhost.com/mymrtg/
or
http://serverip/mymrtg/

Visit MRTG web site.

Don't let your neighbors or intruders connect to your wireless network. You should replace the default passwords on every device you purchase with passwords of your own. It means that every router, access point or other networking device comes with the same password. Imagine how many ""dlink"" networks there would be in the world if none of our customers renamed their routers? Hackers make it a point to know every company's default passwords. By simply defining a new password, one that will certainly be easier for you to remember than the default, you will establish the protection you need to halt hackers from accessing your network or devices.
