    Anonymous Proxy Gateway


    I have a research project to setup a proxy server such that clients can login to the server and use this server to access the internet. The clients are not in the same network as the Server. When the client surfs the net the clients information (IP) is hidden and the servers information (IP) is displayed.

    I have no idea where to start. I know SQUID is a proxy server but most documentation I've read is about setting up squid for use within a network.

    I need to setup something similar to the 'anonymous proxy servers' that float around the net to protect you IP except that I want to be able to have some sort of security or control over who uses the proxy so no fly-by-night hacker tries to use my system.

    I have a SuSE 10 machine to setup as a Proxy Server.

    Any thoughts?

    I believe It should be exactly the same. In a private network the IP's would not be valid externally (normally) so squid directs querys to the interface with a valid external ip. but in your case that would be the same interface, only your clients must have direct access anyway in order to see your proxy server, and then setup to use it as a proxy, I think the bigger problem would be configuring tru anonymity ( I imagine you can do tht in squid but I dont know) ... if I browse to www.whatismyip.com or similar it can detect my private ip (on that is invalid on the internet like 192.168.x.x 172.16.x.x 10.x.x.x) so if you were using it as an anonymous proxy for a valid ip address it wouldnt be much use

    i have configured squid3 on centos5 for anonymity but it's not working,it show the following error.can any one help me

    ERROR
    The requested URL could not be retrieved

    The following error was encountered while trying to retrieve the URL: Google

    Socket Failure

    The system returned: (99) Cannot assign requested address

    Squid is unable to create a TCP socket, presumably due to excessive load. Please retry your request.
