Using ssh as proxy/tunnel between Mac OS and Linux

How to connect to remote computer with private key by using ssh:

#register private key
ssh-add ~/dev/Private/ludek_vodicka_dsa.openssh

#connect to computer and forward local port to remote computer and remote port
ssh my-computer.com -p PORT -lUSER -L LOCAL_PORT:REMOTE_COMPUTER:REMOTE_PORT

#connect to computer and create SOCKS proxy on port SOCKS_PORT
ssh my-computer.com -p PORT -lUSER -D SOCKS_PORT

Note:

If your private key was created for Windows, it will probably not work on linux/mac. It’s necessary to convert it by using puttygen (on mac or windows). You need to open it by puttygen and choose “Save as openssh” from menu.
