Hi Phillipp, developers; I likewise just submitted a patch for similar. It i buried under the thread named OpenSSH contract development / patch.

Hello, I hope it's the correct ML to get support for "advanced" ssh use (sorry if it's not the case) And I would be very grateful if someone could help me on this issue. Here is my challenge : - I have X devices (around 30) and one SSH server - Each of them have a unique public key and create one dynamic reverse port forwarding on the server - All of them connect with the

...arameter for each pubkey in the authorized key file and then be able to identify which device did the established connection. For example I try to set an environnement variable for each pubkey in the authorized file but can't get it when doing reverse forwarding. Then I try to have a different permitlisten port but it doesn't work with dynamic port :(. Can i create a tunnel for each device or execute a specific command to identify a posteriori which device created the reverse forwarding port?
