Being a user of Linux, I got used to change the port of SSH on my Mac with the following line:
sudo vi /etc/sshd_config
Then I could change the number and uncomment the following line:
#Port 22
Sadly I noticed that it makes my IPv6 SSH connection unavailable on the new port (neither on the previous port 22).
The real clean way of changing a Mac OS X Daemon is in the plist files
So now I just changed the port in the ssh.plist file and my SSH Daemon runs on IPv4 and IPv6, on the new port.
sudo vi /System/Library/LaunchDaemons/ssh.plist
And modify as following if you want the port to become 22222:
<key>Sockets</key> <dict> <key>Listeners</key> <dict> <key>SockServiceName</key> <string>22222</string> <key>Bonjour</key> <array> <string>22222</string> <string>sftp-ssh</string> </array> </dict> </dict>
You can add 2 lines to make SSH available only via IPv4:
<key>Sockets</key> <dict> <key>Listeners</key> <dict> <key>SockServiceName</key> <string>22222</string> <key>SockFamily</key> <string>IPv4</string> <key>Bonjour</key> <array> <string>22222</string> <string>sftp-ssh</string> </array> </dict> </dict>
