Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, (and here’s the key part) without special hardware. It’s intended for users with multiple computers and monitors on their desk. Run synergys (the server daemon) pointing to your configuration file on one computer. You can run it as your regular desktop user too Then run the synergyc (client daemon) on the other computer and give it the ip address of the server computer.

These two scripts are called when you start a qemu or kvm virtual machine. I removed the openvpn –mktun and –rmtun commands because qemu handles it for you.

Most content on the Internet - from the latest political news to up-to-the-minute sports scores and stock quotes - is free to consumers. Why? Because of effective Internet advertising. What makes it effective is the technologies that allow advertisers, analytics firms, websites, and others to make inferences about consumer tastes and provide relevant content. Network Advertising Initiative allows you to opt out of allowing ad networks to monitor your browsing habits.

My new mobo has two gigE ports, so I figure why not trunk them together to work as one network device? This will work great for a Linux based network storage device (NAS). This will create a virtual interface named bond0 with the external ip address of 192.168.1.100. Anything else on my network will see this computer with this address. It doesn’t matter which interface is actually plugged in, one, the other, or both. As long as one is plugged in it will continue to function.

Opportunistic locking is part of the Windows client file caching mechanism. Samba implements opportunistic locking as a server-side component of the client caching mechanism. Samba/CIFS doesn’t play nice with NFS, so if you’re in a mixed environment where some windows machines access and modify the same files that Linux or Solaris touch through NFS, then disable the oplocks. This is important for things like database files to avoid corruption!

Here’s a bunch of ways to get the ip addresses for all your network interfaces using ifconfig.
