Note this should map all normal ip devices, including MSWindown, OSX, and etc. This software requires knowledge of local area networking and Internet protocol basics. i.e. you should know what an ipaddress (equivalent of a phone number or house address for a computer) is and how it is used.
Step 1: Installation.
From the command line go to where you downloaded it to and install it.
$ cd (download directory)
$ sudo dpkg -i jNetMap-0.5.deb
If your Debian based repository supports it:.
$ sudo apt-get install jnetmap
Go to the Applications menu > Internet > jNetMap to run it.
Step 2: Your First Network Map.
Since you probably have not done a map before, You will want to choose "Create a new map of your network".
Then you will want to go to the menu and go Tools > Network scanner.
That you give you a screen to choose you network. It defaults to 192.168.1.1. You need to make sure that is correct.
Either from the command line:
or go to your desktop and display Connection information.
Once you are sure that the network is right, press the scan button.
Step 3: Results?
You should get a network map. You may have to use your mouse to arrange the connections.
If you click on one of the devices you should get additional information about that device at the right hand column.
You can even get port information by going to Tools > Port scanner. I did a port scan on a printer server (192.168.1.99)
Step 4: Other Possiblilities
Step 5: Identifying the Maker of a Nic.
There are other tools to look at for getting information about your network. They usally require admin rights and or a bit more experience with netowrking. Here are just two:
nmap (with a gui front end such as zenmap)
