Web Interface for the Guthrie Database can be accessed here:

As an example we will add pinger.aup.edu.pk in the database. 
The main page contains a Table of Nodes already present in the database. There is a search box, at the top of this table to search against all the columns.
We first search for any other entry containing the word 'aup' in it. 
We see there is just one other entry and it is disabled. We will now create a new entry.
On clicking the button 'Create' we see the following interface: 
We now enter the IP address of the Node. 
Entering the Nodename of the host, which is pinger.aup.edu.pk 
Next is site name. This should be aup.edu.pk
