Hello, I try use use port knocking and would be happy to do this in ssh config file. To open the port I can use ProxyCommand with an wrapper script like ProxyCommand bash -c 'wrapper.sh %h port1 port2 ... portX; nc %h %p' so far so good. But if I understand port knocking in the right way I must close the port after disconnect? I havened found a way for this like post-connect in ssh config. Has anyone a suggestion how it can be implemented?
Any reasons why you can't let your firewall handle the port nocking functionality?
