Do you have telnet open to the outside world? If so kill it and only
allow ssh with the proper extra security setup. You may need to open
telnet for a little while for testing purposes, but don't leave it
that way.
What has using the telnet client for testing a daemon on a tcp port to
do with running a telnet daemon?
Answer: nothing.
