I completed removed and reinstalled macports after an upgrade to 10.13.6. I have Xcode 10.0 installed and fully updated with the latest Command Line Tools update.
When I installed rsync, I executed the command that was suggested by the port command. I forget what it was. After a reboot, every 30 seconds, I see this in /var/log/system.log: com.apple.xpc.launchd[1] (org.macports.rsyncd[1044]): Service exited with abnormal code: 2 /opt/local/etc/rsyncd.conf is the one I've used for a while. I looked through the mailing list archives, but didn't see anything. Ideas? Thanks.
