Pretty simple, I know that this has happened to me before. Couldn't find a good answer on AU.
I was running an ssh session with ports bound:
ssh -L 3000:<server_name>:22
I just lost my connection. When I try to reconnect using the same command, I get the following error:
bind: Address already in use channel_setup_fwd_listener: cannot listen to port: 3000
How do I reset ssh on my machine to allow the port to be bound again? Resetting the local machine works.
