What's the racoon doing in my apple?
From Apple's documentation:


  racoon speaks the IKE (ISAKMP/Oakley) key management protocol, to establish security associations with
  other hosts.  The SPD (Security Policy Database) in the kernel usually triggers racoon.  racoon usually
  sends all informational messages, warnings and error messages to syslogd(8) with the facility
  LOG_DAEMON and the priority LOG_INFO.  Debugging messages are sent with the priority LOG_DEBUG.  You
  should configure syslog.conf(5) appropriately to see these messages.
