How to start Syslogd server on Mac to accept remote logging messages?

Question

Anyone knows how to start Syslogd server on Mac to accept remote logging messages?

I started Syslogd, but seems it doesn\'t accept remote messages.

If I do a net

Syslogd should already be running on your system; what you need to do is enable its UDP listening option. This is controlled by a section near the end of /System/Library/LaunchDaemons/com.apple.syslogd.plist; remove the comment markers so that it looks like this:

                NetworkListener
                
                        SockServiceName
                        syslog
                        SockType
                        dgram
                
        

And then reload the syslogd daemon either by rebooting, or by running:

sudo launchctl unload /System/Library/LaunchDaemons/com.apple.syslogd.plist
sudo launchctl load /System/Library/LaunchDaemons/com.apple.syslogd.plist

UPDATE: Starting in OS X v10.7, Apple switched com.apple.syslogd.plist to a binary plist format, which doesn't include the relevant comment, and isn't editable as plain text. With the new format, PlistBuddy seems to be the easiest way to add the listener:

cd /System/Library/LaunchDaemons
sudo /usr/libexec/PlistBuddy -c "add :Sockets:NetworkListener dict" com.apple.syslogd.plist
sudo /usr/libexec/PlistBuddy -c "add :Sockets:NetworkListener:SockServiceName string syslog" com.apple.syslogd.plist
sudo /usr/libexec/PlistBuddy -c "add :Sockets:NetworkListener:SockType string dgram" com.apple.syslogd.plist
sudo launchctl unload com.apple.syslogd.plist
sudo launchctl load com.apple.syslogd.plist
