Hi !

I am not an expert on the subject.

But as far as I know the recomendation is not to use the well known
ports (below 1024). To me it lookslike the problem tend to increase
along the coming years, every day more and more software need TCP ports,
the conflicts will be greater.

I have read on this list some weeks (months ?) ago about a techinique on
windows where one could reserve a port, when an app request a random
free port windows will not supply any reserved port unless asked for
that exactly port number.

Don't know how to do it on Unices. But it could help you to workaround
your issue.

see you !
