One Keyboard and mouse, Many OS’s, Monitors and Computers

Today I’m going to talk a little bit about Synergy. Synergy is a free (as in beer and speech) piece of software that allows you to use one keyboard and mouse with multiple computers. This differs from a traditional KVM in a couple ways. 1. You get the added screen real estate as each machine needs their own screen 2. You don’t need additional hardware the keyboard/mouse switching is done over your existing network. The advantage of this is that Synergy is cross platform, there are currently Synergy clients for OS X, Linux and Windows (No official support for Vista however, It may be possible but your mileage may vary. let me know how you make out if you try it) so you can have a Windows XP machine on the left monitor an Apple machine on the center monitor and a Linux machine on the right monitor or you could have 3 machines all with the same OS.

Redirect LAN users wherever you want

How-To spy on other users on the local network

Sometimes it’s nice to know what kind of people you’re sharing a LAN with. This hack will allow you to sniff packets from other users on the Local Switched network. What we accomplish by ARP spoofing is tricking a host on the LAN into forwarding us packets that normally would only be sent to the gateway (or the machine or router thats going to send them off to the internet)

****Disclaimer****
This should only ever be done on a network that you run or otherwise have permission to monitor other users activities.
