Email from warren Matthews 10:25pm 5 May, 2001 PDT I installed pipechar, here is the output. Don't be confused by seeing "pchar" I had to rename the binary so sudo would let me run it. Is the UDP connection refused usual ? $ sudo ./pchar rtlin1.dl.ac.uk ./pchar [Beta830-2K] : Sending UDP packet failed; Error<111> Connection refused ./pchar [Beta830-2K] : Sending UDP packet failed; Error<111> Connection refused 0: localhost [26 hops] ./pchar [Beta830-2K] : Sending UDP packet failed;
