It turned out that Apple changed service startup process in Mac OS X 10.4 (Tiger) to what is called launchd. So you may guess that changing port number in /etc/sshd_config didn't help and there was no /etc/inetd.conf or xinetd equivalent. At this point it became more interesting.
Finally I've come to the following procedure:
- Add a new service to the /etc/services file. I've called it ssh-NNNN, where NNNN is desired port number (this name is not a requirement and is only for clarity). So I've got a new line like:
ssh-NNNN NNNN/tcp
in /etc/services.
- Find a file named ssh.plist in /System/Library/LaunchDaemons. In this file find the following text:
<key>SockServiceName</key> <string>ssh</string> and change ssh to a new service name ssh-NNNN.
- That's it. Now just start or restart SSH service from the System Preferences. Also, don't forget to open required port on the firewall (I leave this up to you)!
