If you want to test connections to random ports, Telnet is what we have used by default but it's not really a great choice because it has all that NVT stuff that might get confused by escape sequences in the data. If you want to see what a port is saying, use netcat. That's what it's for. FWIW, my Mac has nc as part of the standard system but not telnet. R's, John
