    I am running osx 10.4

    I have all services turned off in the firewall pane. I read somewhere that telnet is available on the system but doesn't show up in the GUI.

    Is there a way for me to see if telnet is running and/or disable it permanently for security purposes?

    Launch Terminal.

    Type

    Code:
    ps auxc | grep telnet
    If it's running you'll get a line that looks something like
    Code:
    user 2086   0.0  0.0    75524    728 s000  S+    6:12PM   0:00.01 telnet
    If it's not running you'll just get another prompt.

    You could also try telnetting to your box from another system. Or even locally from a Terminal. This is what I get:

    This only proves that the normal telnet port (25) does not have a listener.
