NAME

     racoon --- IKE (ISAKMP/Oakley) key management daemon

SYNOPSIS

     racoon [-46BdFLVv] [-f configfile] [-l logfile] [-P isakmp-natt-port]
        [-p isakmp-port]

DESCRIPTION

     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.

     -4

     -6      Specify the default address family for the sockets.

     -B      Install SA(s) from the file which is specified in racoon.conf(5).

     -d      Increase the debug level.  Multiple -d arguments will increase
         the debug level even more.

     -F      Run racoon in the foreground.

     -f configfile
         Use configfile as the configuration file instead of the default.

     -L      Include file_name:line_number:function_name in all messages.

     -l logfile
         Use logfile as the logging file instead of syslogd(8).

     -P isakmp-natt-port
         Use isakmp-natt-port for NAT-Traversal port-floating.  The
         default is 4500.

     -p isakmp-port
         Listen to the ISAKMP key exchange on port isakmp-port instead of
         the default port number, 500.

     -V      Print racoon version and compilation options and exit.

     -v      This flag causes the packet dump be more verbose, with higher
         debugging level.

     racoon assumes the presence of the kernel random number device rnd(4) at
     /dev/urandom.

RETURN VALUES

     The command exits with 0 on success, and non-zero on errors.

FILES

     /etc/racoon.conf  default configuration file.

HISTORY

     The racoon command first appeared in the "YIPS" Yokogawa IPsec
     implementation.

SECURITY CONSIDERATIONS

     The use of IKE phase 1 aggressive mode is not recommended, as described
