What software do I need to setup my own proxy site like http://5z4.net/ and http://browserproxy.com/ ? Any help would be greatly appreciated.
Download any popular proxy script, they usually have a readme. Mostly all you'll need to do is upload the files to a directory on your server. Bit more to it when it comes to optimizing and tweaking your server so it doesn't explode when it gets a lot of traffic, but that's the basics
I recommend PHProxy (the second link of the above poster). I use 0.4 for my proxy and it's handling fine.
Or you can download free ready made proxy templates which comes with the proxy script. All you need to do is upload and customize. http://www.freeproxytemplates.com
Hey thanks davet for opening this thread and thank you all for the answers. I wanted to start a thread on this. Well I have a question here if anyone can help. Is there anyway this proxy can use multiple IPs? And what about security. I would prefer to use my company server through proxy even when I am traveling around. I want to do it basically for security reasons but I am still not sure about safety involved with proxy browsing.
If you want your proxy to work on multiple ips you have to have multiple network cards in a single system handling multiple ips and Apache set up to listen on all the IPs that your network cards are handling. If you want to use your company system to browse the net you don't want to use a web-proxy. You need to get your company to set up a real proxy. You then just tell your brower to use the proxy and you're good to go. Apache can be set up to act as a forward and reverse proxy although I've never used it as a forward proxy (what you want). http://www.serverwatch.com/tutorials/article.php/3092521 A real proxy can use SSL and have password protection so it's not open to the whole world.
