You can either add the numeric port you want to the array in the plist or add the numeric port you want to /etc/services with your own identifier, like my-ssh-alt and change to that in the plist. cp /System/Library/LaunchDaemons/ssh.plist /Library/LaunchDaemons/istĮdit the line just under the SockServiceName it is a string of the port number or port alias, hence why changing /etc/services works. Otherwise copy it, with a different name, to /Libary/LaunchDaemons and edit that copy. If you don't want it listening on port 22 anymore, you can just edit this file. The configuration you're after is /System/Library/LaunchDaemons/ssh.plist plist files in /Library/LaunchDaemons and /System/Library/LaunchDaemons The system directory being installed with the OS, and the non system is added after installation. You'll also notice that if you run an lsof on the launchd process you'll see it listening on port 22.
You'll notice that if you run a ps -ax | grep sshd none of them are listening on port 22. Inetd can be configured to listen on a port and launch the appropriate command, rather than the command starting in daemon mode, same with launchd. Listening on port 22 is handled by launchd, which is the equivalent of Unix's init, inetd and cron. To put the system back, redo the above steps and change the ssh port back to 22. Verify you can access the system by logging in with ssh using this command: Sudo launchctl load -w /System/Library/LaunchDaemons/ssh.plist Now enter the following command to start SSH again: Sudo launchctl unload /System/Library/LaunchDaemons/ssh.plist If it is not, the first command will fail ignor it and move on to the second to start ssh. Depending on your system setup, ssh may not be running. There will be two entries, one for tcp and the other for udpĬhange the number 22 in both cases to 22222 or your desired port number. Use the slash command to find the ssh service /ssh.

You'll be prompted for you password and obtain an elevated security privilege to make changes. Say you want to change the default port 22 to port 22222 Launchd 1 root 47u IPv4 0xad7e82fd2eeb3f67 0t0 TCP *:22 (LISTEN) Launchd 1 root 20u IPv4 0xad7e82fd2eeb3f67 0t0 TCP *:22 (LISTEN)

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin # This is the sshd server system-wide configuration file. This Methods describing before doesn't works too for me on MojaveĪny suggestions where is the port settings I can change? Want to change 22 port listening for incoming SSH connections for any from 2222x further for security reasons.Ĭhanging /etc/ssh/sshd_config make no sense. MacOS X Mojave 10.14.2, Kernel Darwin 18.2.0
