How to set port in ssh command parameters?

Question

SSH

I set up access by key, disabled it by password, changed the standard port 22 to my own.
I set up port knocking
. And when I try to log in to the local host
ssh 192.168.0.100 -l root
, the connection error says that it is trying to do this on port 22, and not on the one that I changed.

PS. When the iptables deny rule is removed, the connection proceeds normally.

Answer 1
