I currently run DD-WRT on a Linksys WRT54GL. One of the great features of DD-WRT is its Simple Network Management Protocol (SNMP) functionality. You can setup a desktop to gather SNMP data from the router and provide it in nice graphical form.

First, you need to configure the router running DD-WRT:

1. Login to the DD-WRT web interface by entering the router's IP address in your browser.
2. Select the Services tab.
3. Click the Enable radio button under SNMP.
4. Enter a description for the location (such as "Home"), a name for the contact (such as "Aaron Gember"), and a name for the router (its hostname is a good choice).
5. Click the Apply Settings button.

After DD-WRT is configured, MRTG needs to be configured. All the commands below are run as root. A few may be Fedora specific, but the commands are easily adaptable for other Linux distributions.

1. Install MRTG

   yum install mrtg

I had SSH enabled on my router running DD-WRT v24 and my SSH key installed, allowing me to SSH into the router. However, I could not remember the password for the web interface. I used the instructions at http://www.righteoushack.net/?p=262 to reset the password by modifying NVRAM values using SSH.
