I need to be pointed in the right direction on how to do this project.
I simply want a gnome panel applet that will run constantly and, when clicked, will display an IM style list of I.P. addresses that are active on the network I am currently connected to. It should be able to have a configuration menu that will allow the user to specify a subnet mask, and frequency of scan.
I am looking for something that will return something similar to the output of:
nmap -sP xxx.xxx.xxx.xxx-xxx
My question is: What language should I learn to make this happen, and is anyone willing to mentor me through the process?
