Adaptive Firewall Statistics for OS X Server

I wrote up afctl (the command line tool to manage the OS X Server Adaptive Firewall) awhile back here One thing I didn’t touch on is statistics. There’s a nice little command called hb_summary located in /Applications/ that provides statistics for blocked hosts. To see statistics about how much the Adaptive Firewall is being used, just run the command with no options: /Applications/ The output provides the following information (helpful if plugging this information into a tool like Splunk):
  • Date
  • Date statistics start
  • Number of hosts blocked
  • Addresses blocked
  • Number of times each address was blocked
  • Last time a host was blocked
  • Total number of times a block was issued
