Have you ever wanted to control 2 computers with the same keyboard and mouse? (Semi-Geek Post)

If the two computers are in the same LAN, you can easily do that. Imagine having two screens connected to two computers, and only one mouse and keyboard connected to the first computer. When your mouse pointer reaches the edge of the screen on your first computer, it jumps to the second computer, along with keyboard control. Moreover, you could even use different operating systems on the two computers, one Windows and one Linux.

The way to achieve this is to use Win2VNC (for Windows) or x2vnc (for Linux). After you install one of these programs on the first computer, you have to install a VNC server on the other computer (I recommend RealVNC). The last step is configuring win2vnc or x2vnc to connect to the VNC server on the other computer. Tip: Tip: Make sure that at least while testing you disable the VNC server authentication, so that it doesn't ask for permission or for a password when win2vnc connects to it. Also, check the firewall permissions on the second computer. I think the default port for RealVNC is 5900.
