Change the SSH Listening Port Leopard 10.5
May 16, 2008
If you need to change the firewall port on SSHD for MacOSX Leopard 10.5
Follow the instructions below
Open Terminal and as edit the file /etc/services (as root)
sudo pico /etc/services
Scroll right down to the bottom and add the line
secret-ssh portnumber/tcp # secret SSH port
portnumber being your desired port number, when this has been added press ctrl & o and write the file out and then ctrl & x to exit
Now you will need to edit the file /System/Library/LaunchDaemons/ssh.plist
sudo pico /System/Library/LaunchDaemons/ssh.plist
Now locate the following
<key>SockServiceName <key>
<string>ssh</string>
and replace with this
<key>SockServiceName</key>
<string>secret-ssh</string>
Reboot & you should be able to connect via SSH using your desired port.
This has worked 100% fine for me let me know if you have any trouble
