## Introduction[edit | edit source]

"A local area network (LAN) is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building using network media.[1] The defining characteristics of LANs, in contrast to wide area networks (WANs), include their usually higher data-transfer rates, smaller geographic area, and lack of a need for leased telecommunication lines."

## Finding other machines on your local network[edit | edit source]

### Under Windows 7[edit | edit source]

Using built-in command langauge

* Open a terminal (comand prompt)
* Type: Net View
* This will show Windows machines and machines that "talk to Windows"

Software to install (no guarantees at all. It's your decision !!!)

* NetResView, provides more information, e.g. sharable parts, workgroups, etc. for windows machines. Doesn't find my Linux machine that has a broken graphics driver :(

* Softperfect NetworkScanner
* Caveat: You will have to register with the company, then give them remote admin rights ...
* The system works as a server talking to your web browser. In an open environment, you could change the port number. In a firewalled one, keep port 80 and shut down any web server or other applications that may use this port (e.g. Skype)
* When you launch the application it will open a page on your web browser, click on inventory (then wait some time)

* NMap (recommended, it will find all devices)
* Multi-OS freeware with a windows frontend.
* The Interface is more complex than what you need, but you can get a lot of information
* Requires you to enter an IP range for scanning, e.g. 168.168.30.1-254
