.Sh DESCRIPTION
.Nm
is used to setup and maintain an IPSec tunnel or transport channel, 
between two devices, over which network traffic is conveyed securely. 
This security is made possible by cryptographic keys and operations 
on both devices.
.\"
.Nm
relies on a standardized network protocol (IKE) to automatically 
negotiate and manage the cryptographic keys (e.g. security 
associations) that are necessary for the 
IPSec tunnel or transport channel to function.
.\"
.Nm
speaks the IKE
.Pq ISAKMP/Oakley
key management protocol,
to establish security associations with other hosts.
The SPD
.Pq Security Policy Database
in the kernel usually triggers
.Nm .
.Nm
usually sends all informational messages, warnings and error messages to
.Xr syslogd 8
with the facility
.Dv LOG_DAEMON
and the priority
.Dv LOG_INFO .
Debugging messages are sent with the priority
.Dv LOG_DEBUG .
You should configure
.Xr syslog.conf 5
appropriately to see these messages.
.Bl -tag -width Ds
.It Fl 4
.It Fl 6
Specify the default address family for the sockets.
.It Fl B
Install SA(s) from the file which is specified in
.Xr racoon.conf 5 .
.It Fl d
Increase the debug level.
Multiple
.Fl d
arguments will increase the debug level even more.
.It Fl F
Run
.Nm
in the foreground.
.It Fl f Ar configfile
Use
.Ar configfile
as the configuration file instead of the default.
.It Fl L
Include
.Ar file_name:line_number:function_name
in all messages.
.It Fl l Ar logfile
Use
.Ar logfile
as the logging file instead of
.Xr syslogd 8 .
.It Fl v
This flag causes the packet dump be more verbose, with higher
debugging level.
.El
.Pp
.Nm
assumes the presence of the kernel random number device
.Xr rnd 4
at
.Pa /dev/urandom .
.\"
.Sh RETURN VALUES
The command exits with 0 on success, and non-zero on errors.

.Sh FILES
.Bl -tag -width /private/etc/racoon/remote/anonymous -compact

.Sh HISTORY
The

.Sh SECURITY CONSIDERATIONS
The use of IKE phase 1 aggressive mode is not recommended,
as described in
