I do seem to be having some basic problem with (tcp)traceroute: tcptraceroute 209.191.118.103 25 Selected device fxp0, address 192.168.16.4, port 56180 for outgoing packets Tracing the path to 209.191.118.103 on TCP port 25, 30 hops max 1 * * * 2 * * * 3 * * * 4 * * * 5 * * * 6 * * * 7 * * * 8 * * * 9 * * * 10 * * * 11 * * * 12 * * * 13 * * * 14 * * * 15 * * * 16 * * * 17 * * * 18 * * * 19 * * * 20 * * * 21 * * * 22 * * * 23 * * * 24 * * * 25 * * * 26 * * * 27 * * * 28 * * * 29 * * * 30 * * * Destination not reached telnet 209.191.118.103 25 Trying 209.191.118.103... telnet: connect to address 209.191.118.103: Operation timed out telnet: Unable to connect to remote host I cannot use (tcp)traceroute with ANY server.
