If you're trying to reach out from (or back in to) a Mac running OS X 10.10 Yosemite, Developer Preview, you may have found that your Bonjour networked machines aren't resolving.
This is because the
mDNSResponderHelper are disabled (for some reason.) To re-enable them, you need to edit the
com.apple.mDNSResponder.plist. You'll find it located at:
You'll find a couple of lines near the top:
Delete those lines, and save.
You'll need to reload and start
mDNSResponder so in the terminal:
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
.local names should now resolve. (Remember to try just the machine name first, as
.local sometimes doesn't resolve properly.)
To check the service is running, use:
ps aux | grep -i dns
You should see
/usr/sbin/mDNSResponder running, if not, try restarting the service as above.
