Wrote down about some #SSH configs I use that might be not so well-known, hope its helpful:
@caarlos0 Thanks, I didn't know about the RemoteCommand for ~/ssh/config. I was always manually doing it (via running an alias)
@caarlos0 thanks a lot!
I actually use tmate a lot as I know nothing about the great things that ssh offers (till now ;) ).
Can the 'open connection' thing you mentioned be used also with a reverse tunnel? If enabled only with preloaded keys, this would make a nice backdoor for inaccessible pcs.
