Well it appears that configd for 10.2 is greedy and doesn't set SO_REUSEPORT. Thanks for the suggestion of the lsof command. You may need to use lsof to find the other process that is binding to that port. It may not be possible to bind to the same port if that process isn't using SO_REUSEPORT. I have created an application which is listening for DHCP traffic on port 68, I am able to bind to this port 68 using a UDP DGRAM socket on 10.4, but when I try to run it on 10.2 it fails with this error: << smime.p7s >> This email sent to site_archiver@lists.apple.com
