[Jetty-support] Permission denied using setuid on Fedora Core 4

[Matthew S. <msh...@fu...>]

Hi all,

Can anyone help me out with a problem using setuid to bind to port 81  
(or 80) on Fedora Core 4 as described in http://docs.codehaus.org/ 
display/JETTY/port80.

I'm getting a "java.net.SocketException: Permission denied" despite  
starting as root, but removing the setuid configuration file seems to  
fix the problem (though jetty's then running as root).

For what it's worth the same setup seems to work as expected on CentOS.

I'm including the exception below - Any help in tracking down what  
I've done wrong would be much appreciated.
