Airport Extreme logging

These routers do support logging, but you have to mutter strange incantations to the Mac OS X (revealing its Unix roots), then point the Airport Extreme with the Airport Utility to the IP address of your machine…according to Mintel:

Change syslogd configuration

# echo "local0.notice /var/log/airport.log" >> /etc/syslog.conf

Touch the logfile

# touch /var/log/airport.log

Change syslogd startup procedure

At the end of the file, uncomment the part to accept remote logging.

# cat /System/Library/LaunchDaemons/com.apple.syslogd.plist

Restart syslogd

# launchctl unload /System/Library/LaunchDaemons/com.apple.syslogd.plist

# launchctl load /System/Library/LaunchDaemons/com.apple.syslogd.plist

Open the firewall

Go the the System Preferences, click Security, open the Firewall tab and click the+. Select the file /usr/bin/syslog.
If you are unable to select the /usr directory, try this hack by opening a terminal and typing:

$ cd

$ ln -s /usr/bin

$ ln -s /usr/sbin

Now you can select the file (in your home directory) ./bin/syslog and ./sbin/syslogd
