Ask HN: Why is there no native SSH hook to run a local command before connecting

Yea I would consider this very poorly documented, although I'm sure the authors would be quick to point out how dumb I am for even suggesting that.

I bet most ssh users don't even know about the -w option. It even supports layer2 tunnels!

And somehow https://wrongthink.link/posts/all-you-need-is-ssh/ does not even mention this usecase.

I have to admit I'm not certain what use case the -w option serves. It seems like a fancy port forwarding?

It's funny how after using an app like ssh/awk/sed/grep for so many years and achieving so much functionality with it with some pretty "advanced" features is still but a scratch on the surface of actual abilities or what other people do with them. I'd wear it like a badge of honor if I ever created something so useful and universally used. To the point, I'd probably even use my initials in the name of the app too!

Check the section in the manpage for ssh(1) named: SSH-BASED VIRTUAL PRIVATE NETWORKS

noticed these replies in my history... personally I think sshtunnel is a lot more convenient most of the time.
