PuTTY configuration equivalent to OpenSSH ProxyCommand

Question

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

Using Linux this is no problem with the ssh -W command.

In PuTTY I can't find the options to create such a connection.

Example under Linux (~/.ssh/config):

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

Anyone knows how to use such a config in PuTTY?

Answer 1

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

The "local proxy command" is:

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

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

See for example:

• My guide for tunneling SFTP/SCP session. It's for WinSCP, but just use PuTTY instead of WinSCP in section Connecting through the tunnel.
