Even though the sshd service is stopped, I can connect to the remote machine

Code: [Select]
~ ❯ doas dinitctl status sshd   
Service: sshd
    State: STOPPED

Code: [Select]
~ ❯ ssh [email protected] -v

but I can't connect to this machine from the remote machine. I get "Connection refused".

Code: [Select]
~ ❯ pacman -Q openssh
openssh 9.9p1-2
~ ❯ pacman -Q openssh-dinit
openssh-dinit 20230906-3

Is this some kind of bug or is it supposed to be like this?

sshd is responsible for accepting connections from ssh clients like ssh

So local sshd stopped means ssh clients cannot connect to the local machine, but that doies not prevent an ssh client from connecting to a remote machine with a running sshd.
