The call to getnameinfo() fails on OSX if the sockaddr actually means a unix socket. Linux, apparently, just fills with "localhost", so do we, if we detect a unix socket. Simple test: $ ncat -lUc 'echo $NCAT_REMOTE_ADDR:$NCAT_LOCAL_ADDR' test & $ ncat -U test This currently fails with: Ncat: getnameinfo failed: Undefined error: 0 QUITTING. With this fix we'll get "localhost:localhost" just like on Linux.
