This time httpd-error gets flooded with these lines, one every second: [Wed May 25 08:09:37 2005] [warn] (61)Connection refused: connect to=20 listener on 0.0.0.0:80 [Wed May 25 08:09:38 2005] [warn] (61)Connection refused: connect to=20 listener on 0.0.0.0:80 The difference is that now an address is shown, 0.0.0.0.
