Enabling telnet, rlogin, and rsh in Mac OS X 10.0.1 and later

Enabling telnet, rlogin, and rsh in Mac OS X 10.0.1 and later
Important:
Telnet, rlogin, and rsh send information (including passwords) over the network unencrypted. OpenSSH provides greater security. You should only revert to telnet, rlogin, and rsh if your network environment requires them.

You must be logged in as an Admin user to follow these steps. After each step in which you type a command, press the Return key.
    1. Open the Terminal utility. 2. Type sudo pico /etc/inetd.conf 3. Type in your admin password. 4. Press Return. 5. The file inetd.conf will open in the pico text editor. Using the arrow keys to navigate, scroll down until you see the lines for: #telnet #shell #login 6. Remove the pound "#" character from the line of each service you want to re-enable. 7. Save the file (press Control-O), press Return, and exit pico (press Control-X). 8. Choose Restart from the Apple menu.
