Objective:

Connect to internet via SOCKS proxy through another machine. It is particlarly useful when:

• The machine you are working on does not allow internet access, but does allow ssh to other machines (which are connected to internet).
• You want to add an extra layer of security and privacy.

Method

Create a SOCKS proxy thourhg ssh tunneling.

ssh -D LOCAL_PROXY_PORT -N -f SSH_SERVER

• -D: Specifies a local ``dynamic'' application-level port forwarding.
• -N: Do not execute a remote command.
• -f: Requests ssh to go to background.

Run a program thorugh a proxy server using proxychains. Install proxychains and add the following to the end of ~/.proxychains/proxychains.conf.

socks5 127.0.0.1 LOCAL_PROXY_PORT

• LOCAL_PROXY_PORT corresponds to the one that you specified in the ssh command.

Example uses:

proxychains wget http://some-website
proxychains git clone https://github.com/som-repository
