I enjoyed reading your blog post on the ‘new’ netcat mode in openssh [0] which arrived with v5.4. The examples were instructive but a little abstract. I’ve used it in the following manner.
ssh -o ProxyCommand=”ssh -W %h:%p jumphost.example.org” server.example.org
Since you mentioned that it was probably a killer feature, I wonder if you have any plans to follow up with another post.
Anyway, it was a great post.
