Socks proxy using SSH
Tunnelling over our Internet link it sounds already exiting, isn’t it?. But how difficult is it? Do we need any complex and sophisticated configuration of hardware and software? Hmm.. it is not necessary even to involve ipsec or ssl stack to create VPN. SOCKS is built in to OpenSSH so it’s trivial to run SOCKS proxy server with ssh client running with option -D. This option configures SSH client to listen on your local Linux box on specified by us tcp port. Then we will use SOCKS5 proxy configuration built into most of Internet browsers to connect to.
