now i'm on a network where the administrator uses squid server to block by keyword, so a whole lot of websites and file extensions are blocked, now using a proxy is a simple solution, but it is a sacrifice on speed.
i remember that i read somewhere about creating your own squid server so as to bypass the administrators squid server blocking.
its done on linux, i'm not much into it, but i know it's not that hard, anyone here who knows something about it (in detail)?
or maybe any other method to beat squid server's keyword blocking?
