Hi, I tried: e:\web\> catalyst Testing e:\web\> cd Testing e:\web\Testing\> perl script/testing_server.pl -p 80 But it gave the message that the app can be accessed on the port 3000. I have also tried to start it on the port 82, but it started on the port 3000. I use perl 5.10.0 and Catalyst 5.80004. Octavian
