SSH Through Intermediate Using Putty

Most of the time when you are forced to access a system through an intermediate hop it is fairly trivial either manually or automating it with ssh config.  That is assuming you are using *nix.  When using putty this is also possible and here is a quick note on what I did.

First off ensure you have a working ssh key to the intermediate host you will be using.

Next setup and save your new putty session as you would for any other connection.

Under Connection -> Proxy pick Local and set the Proxy hostname to your intermediate host (I set port to 0 but port does not matter).

Under local proxy command set something like this:

plink.exe %proxyhost -l root -agent -nc %host:%port
