I wrote this back in 2009 but I have reposted it upon request. I hope it is helpful.
Do you want to remotely control a PC with a Mac? There are many commercial software packages and online services available. However, viagra sale most of them are simply re-brandings of the open source VNC remote control system. Plus, click you may find their performance to be lacking. I’ve been using VNC between Windows, click Mac and Linux systems for a long time. With the resurgence in Mac interest, a lot of people ask me how they can access their existing Windows PC from their new Mac. Here is a quick and easy guide to getting a remote control system up and running using VNC. And by the way, its free.
VNC (Virtual Network Computing) was originally developed in Cambridge, U.K., by developers at the AT&T/Olivetti Research Laboratory. It is a high performance remote control system that includes two software components. The remote computer has the “server” component running, while the other computer runs the “client” component and connects to the remote computer.
(For all you Linux and Unix users, this guide applies to you as well, but note that most Linux and Unix distributions come with VNC already installed. On those systems, you may need to configure VNC and then issue a “vncserver” command.)
1. Getting VNC “server” running on your Windows PC
First, download the free edition of RealVNC onto your Windows PC. (Note that Vista users may have trouble with the free version and if so, they can install TightVNC. Some people prefer TightVNC for all versions of Windows, but because it has several advanced features it may be a little more confusing for first-time VNC users.)
Next, install your VNC software and specifically choose to install the server component, register the service, and start the service. Now VNC server should be running on your Windows PC. You can set the password for remote access if you like. You should see a small icon at the bottom right of your screen. By resting on the icon, you should see your computer’s network IP address on your LAN. Make a note of it!
Finally, you need to either disable the Windows firewall on your PC or else open ports 5900 and 5800 in the Windows firewall. If you are opening ports, I recommend that you open 5901 and 5801 also.
2. Getting VNC “client” running on your Mac
