Temp Telnet Activation

[Dave Higgins]

Hi there.

I understand that standard telnet access is disabled on OS X for a good 
reason (and ssh is better to use), but I need to know how to 
temporarily turn it on and then off. A one-liner Terminal / shell 
command would be best for activating (rather than a startup config type 
setting).

As for deactivating, a simple kill on the process ID would probably 
work (assuming the PID is easy to find (/var/run/telnet.pid maybe?))

Seems I read once how to do this, but a Google search retuned WAY too 
many unrelated hits (guess I just didn't hit the right search phrase).

Thanks for any help.

Dave.
