|
|
The
|
|
.Nm
|
|
utility adds, updates, dumps, or flushes
|
|
Security Association Database (SAD) entries
|
|
as well as Security Policy Database (SPD) entries in the kernel.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility takes a series of operations from the standard input
|
|
(if invoked with
|
|
.Fl c )
|
|
or the file named
|
|
.Ar filename
|
|
(if invoked with
|
|
.Fl f Ar filename ) .
|
|
.Bl -tag -width indent
|
|
.It Fl D
|
|
Dump the SAD entries.
|
|
If with
|
|
.Fl P ,
|
|
the SPD entries are dumped.
|
|
.It Fl F
|
|
Flush the SAD entries.
|
|
If with
|
|
.Fl P ,
|
|
the SPD entries are flushed.
|
|
.It Fl a
|
|
The
|
|
.Nm
|
|
utility
|
|
usually does not display dead SAD entries with
|
|
.Fl D .
|
|
If with
|
|
.Fl a ,
|
|
the dead SAD entries will be displayed as well.
|
|
A dead SAD entry means that
|
|
it has been expired but remains in the system
|
|
because it is referenced by some SPD entries.
|
|
.It Fl h
|
|
Add hexadecimal dump on
|
|
.Fl x
|
|
mode.
|
|
.It Fl l
|
|
Loop forever with short output on
|
|
.Fl D .
|
|
.It Fl v
|
|
Be verbose.
|
|
The program will dump messages exchanged on
|
|
.Dv PF_KEY
|
|
socket, including messages sent from other processes to the kernel.
|
|
.It Fl x
|
|
Loop forever and dump all the messages transmitted to
|
|
.Dv PF_KEY
|
|
socket.

The upper layer protocol to be used.

You can use one of the words in

as

|

as well as

|
.Li icmp6 ,

or
|

.Li any .
|
|
.Li Any
|
|
stands for
|
|
.Dq any protocol .
|
|
The protocol number may also be used to specify the
|
|
.Ar upperspec .
|
|
A type and code related to ICMPv6 may also be specified as an
|
|
.Ar upperspec .
|
|
The type is specified first, followed by a comma and then the relevant
|
|
code.
|
|
The specification must be placed after
|
|
.Li icmp6 .
|
|
The kernel considers a zero to be a wildcard but
|
|
cannot distinguish between a wildcard and an ICMPv6
|
|
type which is zero.
|
|
The following example shows a policy where IPSec is not required for
|

|
|
NOTE:
|
|
.Ar upperspec
|
|
does not work in the forwarding case at this moment,
|
|
as it requires extra reassembly at forwarding node,
|
|
which is not implemented at this moment.
|
|
Although there are many protocols in
|
|
.Pa /etc/protocols ,
|
|
protocols other than TCP, UDP and ICMP may not be suitable to use with IPsec.

|
|
.It Fl P Ar direction Li discard
|
|
.It Fl P Ar direction Li none

|
|
.Ar protocol/mode/src-dst/level Op ...
|
|
.Xc
|
|
.Ed
|
|
.Pp
|
|
The direction of a policy must be specified as
|
|
one of:
|
|
.Li out ,
|
|
.Li in ,
|
|
.Li discard
|
|
.Li none ,
|
|
or
|
|
.Li ipsec .
|
|
.Li Discard
|
|
means that packets matching the supplied indices will be discarded
|
|
while
|
|
.Li none
|
|
means that IPsec operations will not take place on the packet and
|
|
.Li ipsec
|
|
means that IPsec operation will take place onto the packet.
|
|
The
|
|
.Ar protocol/mode/src-dst/level
|
|
statement gives the rule for how to process the packet.
|
|
.Ar Protocol is specified as
|
|
.Li ah ,
|
|
.Li esp
|
|
or
|
|
.Li ipcomp
|
|
The
|
|
.Ar mode
|
|
is either
|
|
.Li transport
|
|
or
|
|
.Li tunnel .
|
|
If
|
|
.Ar mode
|
|
is
|
|
.Li tunnel ,
|
|
you must specify the end-point addresses of the SA as
|
|
.Ar src
|
|
and
|
|
.Ar dst
|
|
with a dash,
|
|
.Sq - ,
|
|
between the addresses.
|
|
If
|
|
.Ar mode
|
|
is
|
|
.Li transport ,
|
|
both
|
|
.Ar src
|
|
and
|
|
.Ar dst
|
|
can be omitted.
|
|
The
|
|
.Ar level
|
|
is one of the following:
|
|
.Li default , use , require
|
|
or
|
|
.Li unique .
|
|
If the SA is not available in every level, the kernel will request
|
|
the SA from the key exchange daemon.
|
|
A value of
|
|
.Li default
|
|
tells the kernel to use the system wide default protocol
|
|
e.g. the one from the
|
|
.Li esp_trans_deflev
|
|
sysctl variable, when the kernel processes the packet.
|
|
.Li Use
|
|
means that the kernel will use an SA if it is available,
|
|
otherwise the kernel will pass the packet as it would normally.
|
|
.Li Require
|
|
means that an SA is required whenever the kernel sends a packet matched
|
|
that matches the policy.
|
|
The
|
|
.Li unique
|
|
level is the same as
|
|
.Li require
|
|
but, in addition, it allows the policy to bind with the unique out-bound SA.
|
|
For example, if you specify the policy level
|
|
.Li unique ,
|
|
.Xr racoon 8
|
|
will configure the SA for the policy.
|
|
If you configure the SA by manual keying for that policy,
|
|
you can put the decimal number as the policy identifier after
|
|
.Li unique
|
|
separated by colon
|
|
.Ql :\&
|
|
as in the following example:
|
|
.Li unique:number .
|
|
In order to bind this policy to the SA,
|
|
.Li number
|
|
must be between 1 and 32767,
|
|
which corresponds to
|
|
.Ar extensions Fl u
|
|
of manual SA configuration.
|
|
.Pp
|
|
When you want to use an SA bundle, you can define multiple rules. For
|
|
example, if an IP header was followed by an AH header followed by an
|
|
ESP header followed by an upper layer protocol header, the rule would
|
|
be:
|
|
.Dl esp/transport//require ah/transport//require ;
|
|
The rule order is very important.
|
|
.Pp
|
|
Note that
|
|
.Dq Li discard
|
|
and
|
|
.Dq Li none
|
|
are not in the syntax described in
|
|
.Xr ipsec_set_policy 3 .
|
|
There are small, but important, differences in the syntax.
|
|

.Sh HISTORY
|
|
The

|
.Nm
|
|
utility first appeared in WIDE Hydrangea IPv6 protocol stack kit.
|
|
The utility was completely re-designed in June 1998.
|
|
.\"
|
|
.Sh BUGS
|
|
The
|
|
.Nm
|
|
utility
|
|
should report and handle syntax errors better.
|
|
.Pp
|
|
For IPsec gateway configuration,
|
|
.Ar src_range
|
|
and
|
|
.Ar dst_range
|
|
with TCP/UDP port number do not work, as the gateway does not reassemble
|
|
packets
|
|
(cannot inspect upper-layer headers).
