Re: Telnet = servname ai_socktype error
TY Dan, I ran the tcpdump on the lo0 interface, ran telnet as shown below, interestingly only the telnet localhost 25 produced an output (which I cannot fully decipher, except for the acknowledgment hand shake and the checksum, but can't figure out the drop or closure event Oddly, telnet localhost smtp and telnet localhost produced nothing in the dumpfile, just the localhost: servname not supported for ai_socktype to stdout [1] mach# telnet localhost localhost: servname not supported for ai_socktype [2] mach# telnet localhost smtp localhost: servname not supported for ai_socktype [3] mach# telnet localhost 25 Trying 127.0.0.1...
