In the conf file there's a: #Port 722 # Secondary port to listen on It might not have been commented out in earlier versions of the port/tarball, not sure. The README explains why the option is available - basically it's an example of a new feature patched in to help you prioritize traffic with your router. -- David Kirchner - dpk@nwserv.com Northwest Web Services - http://www.nwserv.com/ On Tue, 23 May 2000, Oscar Ricardo Silva wrote: > Thanks to Dave Kirchner and Alan Clegg for the incredibly fast and > completely useful responses.
