Transparent SSH host-jumping (Expert)
A while ago in the Transparent SSH host-jumping (Advanced) post I described a technique on how one could jump quite effortlessly through a chain of intermediate hosts. However, there was a catch: the user names and ports across the whole chain should be the same and there was no easy way to change that. Given that I recently paid quite a lot of attention to the ProxyCommand directive I decided to look into the implementation of a helper script that will allow one to tweak parameters for hosts in the chain.
