I am in a LAN and have to use a proxy given to access the web in a very limited way. I can't even use google, github.com or SE sites. However I can use ssh to log into a server, which I have root access so basically I can do anything I want with it. So I was thinking that maybe I could use that server as a proxy so I can visit sites through it.

I tested it using ssh -vT [email protected] which gave a proper response. And In my computer I can't do this.

Also I tried downloading something from the gun.org using wget, which can't be done in my computer too. And it succeeded on that server.

I don't know if that's enough to say that this server have full access to the Internet. But I assumed so and I installed squid3 on it. After trying some while, I failed to get it working.

I got this after I run squid3 -k parse

2012/07/06 21:45:18| Processing: http_access allow all

I deleted some allow and deny rules and added http_access allow all so that all the request would be allowed.

After configuring my computer, I got this error:

Access control configuration prevents your request from being allowed at this time. Please contact your service provider if you feel this is incorrect.

And the log in the server showed that my TCP requests had all been denied.

So, first of all, is what I am trying to do achievable? If so, how to configure the squid in the server so that I use it as a proxy to surf the Internet?

My computer and the server both run Ubuntu11.04.

Thanks for any help~
