David, 1024 and below are considered "well known" ports and are reserved for things like telnet, ftp, http, etc.
You need to be careful assigning private ports so you don't tramp on other assignments. netstat will show you your current assignments.

If you are in the Unix/Linux world and you need to bind to ports below 1024, you need to run/start as root, then (generally you should) drop the rights of root once you have done it. -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Drew William Henderson Sent: Tuesday, 11 January 2011 2:14 PM To: U2 Users List Subject: Re: [U2] Sockets problem It's been a couple years, but i believe ports in the lower range can only be linked to root processes.

We are finding that using a port less than 1024 results in an error 34 "SCK-EACCESS Attempt to connect datagram socket to broadcast address failed because setSocketOption Broadcast is not enabled". Ports from 1024 upwards don't have this error. Anyone have an idea what's going on ?
