PuTTY configuration equivalent to OpenSSH ProxyCommand

Question

I'm just trying to use PuTTY to connect SSH to my servers. These servers only allow incoming SSH from another specific server ("MySshProxyingServer" in the example below).

Using Linux is not a problem with the ssh -W command.

In PuTTY, I cannot find the options for creating such a connection.

Linux example ( ~/.ssh/config ):

 Host MyHostToConnectTo Hostname xx.xx.xx.xx User root Identityfile ~/.ssh/id_rsa ProxyCommand ssh MySshProxyServer -W %h:%p 

Does anyone know how to use such a configuration in PuTTY?

Answer 1

The equivalent in PuTTY is the “local proxy command”. You can use plink.exe with the -nc switch instead of ssh with the -W switch:

"Local proxy command":

 plink.exe % user@ %proxyhost -P %proxyport -nc %host:%port

An alternative is to first open the tunnel using MySshProxyServer using another PuTTY (or Plink) instance.

See for example:

• My guide to tunneling an SFTP / SCP session . This is for WinSCP, but just use PuTTY instead of WinSCP in the Connecting Through a Tunnel section.
