Suppose there is some server running on remotehost.some.where:4444. I have a software that insists to connect to localhost:5555. I can forward this with
ssh -L 5555:remotehost.some.where:4444 myuser@localhost
But this requires an unnecessary ssh connection to localhost, which the addition of
-N would not prevent. How can I do this port forwarding without the login, possibly with another tool?
