telnet localhost on Mac OS X Lion, and this is the output I got.
Trying ::1... telnet: connect to address ::1: Connection refused Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused Trying fe80::1%lo0... telnet: connect to address fe80::1%lo0: Connection refused telnet: Unable to connect to remote host: Connection refused
It tries three different addresses. I would have expected it to only try 127.0.0.1, or at least to try it first. What are these other addresses?
