Macos – SSH HTTP tunneling on OS X


On Windows I use PuTTY to tunnel to my home server and tell Firefox to use PuTTY as a proxy. How would I accomplish something similar on my Mac?

MacOSX ssh client is based off OpenSSH.

ssh -D <port number>

You want the -D flag for dynamic application-level port forwarding.

From the man-page -

Specifies a local "dynamic" application-level port forwarding. This works by allocating a socket to listen to port on the local side, optionally bound to the specified bind_address. Whenever a connection is made to this port, the connection is forwarded over the secure channel, and the application protocol is then used to determine where to connect to from the remote machine. Currently the SOCKS4 and SOCKS5 protocols are supported, and ssh will act as a SOCKS server. Only root can forward privileged ports. Dynamic port forwardings can also be specified in the configuration file.
