The server is running macOS Mojave 10.14.4. I'm unable to get the SSH daemon to start. After logging in locally, I run:

$ launchctl list | grep ssh
-   0   com.openssh.ssh-agent
$ ps -A | grep ssh 
1483 ??         0:00.00 ssh-agent -s
8483 ??         0:00.00 ssh-agent

The service is not active. To resolve this, I've tried:

$ sudo launchctl unload /System/Library/LaunchDaemons/ssh.plist
$ sudo launchctl load -w /System/Library/LaunchDaemons/ssh.plist
$ sudo launchctl stop com.openssh.sshd 
$ sudo launchctl start com.openssh.sshd 
$ eval `ssh-agent -s`                                                                                  
Agent pid 9055

I'm not having any luck. The last thing I attempted before having to take a break from trying to solve this issue was:

$ /usr/sbin/sshd -d     
debug1: sshd version OpenSSH_7.9, LibreSSL 2.7.3
Could not load host key: /etc/ssh/ssh_host_rsa_key
Could not load host key: /etc/ssh/ssh_host_ecdsa_key
Could not load host key: /etc/ssh/ssh_host_ed25519_key
sshd: no hostkeys available -- exiting.

I then ran $ ssh-keygen -A but still receive the same message.

For enabling the SSH service/daemon in MacOS do:

sudo systemsetup -setremotelogin on

For disabling the SSH service do:

sudo systemsetup -setremotelogin off

For checking whether it is on or off:

 sudo systemsetup -getremotelogin 

(Tested with Mojave)

Btw, sshd has to be run as root, not as you are running it. It has to be:

sudo /usr/sbin/sshd -d &
  • I have tried setremotelogin off then setremotelogin on but it's not effective – cryptic Apr 27 at 19:11
  • @cryptic Mojave here and working, what do you have? Was it too fast? How you tested? Using sudo? It has got to be as root. – Rui F Ribeiro Apr 27 at 19:35
  • I'm on Mojave as well. You're right, I didn't run sshd as root which is not right. SSH is working now but I think the problem was that a different version of OpenSSH was also installed via Homebrew and was conflicting with the system version in some way – cryptic Apr 27 at 19:48
