ssh -D 1337 -f -C -q -N user@remote -p 22

• -D 1337 tells ssh to launch a SOCKS server on port 1337 locally.
• -f forks the process into the background.
• -C Turns on compression.
• -q enables “Quiet mode”, since the purpose here is only to tunnel we don’t really care about error output and such.
• -N tells ssh that no commands will be sent (-f complains if we don’t specify this).
• -p specifies what port to use; obviously this is defaulted to 22 so the statement above is pointless, but if you’re a clever fellow you’re probably not running SSH on port 22 🙂
