Finger Port

I am trying to learn Linux and am new to the OS. I have installed with default installation and am now trying to figure a few things out. I want to use the finger server port 79 in order to test some things and then would like to disable it again. I have added necessary information to services, and to inetd.conf related to the man tables. I have rebooted. I can run finger locally but not from another computer on the network directed to my Linux box. I also try to look at processes running and I don't see inetd running. Is there something I have to do in order to get finger and telnet to operate because I haven't been able to find anything in your help files. Thanks, Glenn Hancock
