.Dt KEY 8
|
|
.Os
|
|
.Sh NAME
|
|
.Nm keyadmin
|
|
.Nd manually manipulate the kernel key management database
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Ar command Op Ar args
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
command is used to manually enter security associations into the kernel
|
|
key/security association database. (See
|
|
.Xr key 4 ).
|
|
.Pp
|
|
Almost any operation offered in the
|
|
.Xr key 4
|
|
API is available to privileged users running
|
|
.Nm .
|
|
Until there is an implementation of an automated key management protocol,
|
|
which will manipulate the key database in a manner similar to how
|
|
.Xr routed 8
|
|
or
|
|
.Xr gated 8
|
|
manipulates the routing tables,
|
|
.Nm
|
|
is the only way of establishing security associations.
|
|
.Pp
|
|
If
|
|
.Nm
|
|
is invoked without any arguments, it will enter an interactive mode, where
|
|
the user can type in
|
|
.Dq Ar command Op Ar args
|
|
interactively, or use
|
|
.Nm
|
|
to enter a single
|
|
.Dq Ar command Op Ar args .
|
|
.Ar Command
|
|
can be one of the following:
|
|
.Bl -inset
|
|
.It Ic del Ar type spi source destination
|
|
.Pp
|
|
Delete a security association between
|
|
.Ar source
|
|
and
|
|
.Ar destination
|
|
of the given
|
|
.Ar type
|
|
and
|
|
.Ar spi .
|
|
Example:
|
|
.Bd -literal
|
|
delete esp 90125 anderson.yes.org rabin.yes.org
|
|
.Ed
|
|
.It Ic get Ar type spi source destination
|
|
.Pp
|
|
Retrieve (and print) a security association between
|
|
.Ar source
|
|
and
|
|
.Ar destination
|
|
of the given
|
|
.Ar type
|
|
and
|
|
.Ar spi .
|
|
Example:
|
|
.Bd -literal
|
|
get ah 5150 eddie.vanhalen.com alex.vanhalen.com
|
|
.Ed
|
|
.It Ic dump
|
|
.Pp
|
|
Display the entire security association table. WARNING: This prints a lot
|
|
of data.
|
|
.It Ic load Ar filename
|
|
.Pp
|
|
Load security association information from a file formatted as documented in
|
|
.Xr keys 5 . If
|
|
.Dq -
|
|
is specified for the
|
|
.Ar filename ,
|
|
load keys from the standard input.
|
|
.It Ic save Ar filename
|
|
.Pp
|
|
Save security association information to a file formatted as documented in
|
|
.Xr keys 5 . If
|
|
.Dq -
|
|
is specified for the
|
|
.Ar filename ,
|
|
place the key file out on the standard output. (This can be used as a sort
|
|
of lightweight
|
|
.Ic dump
|
|
command.)
|
|
NOTE: The
|
|
.Ic save
|
|
command must create a new file; it will not write into an
|
|
existing file. This is to prevent writing into a world-readable file, or a
|
|
named pipe or UNIX socket (see
|
|
.Xr socket 2
|
|
and
|
|
.Xr mkfifo 1 ).
|
|
.It Ic help Op command
|
|
.Pp
|
|
Offer brief help without an argument, or slightly more specific help on a
|
|
particular command.
|
|
.It Ic flush
|
|
.Pp
|
|
Erase all entries in the kernel security association table.
|
|
.El
|
|
.Pp
|
|
The following values for
|
|
.Ar command
|
|
are only available by using
|
|
.Nm
|
|
in its interactive mode of operation:
|
|
.Bl -inset
|
|
.It Ic add Ar type spi source destination transform key
|
|
.Op Ar iv
|
|
.Pp
|
|
Add a security association of a particular
|
|
.Ar type
|
|
and
|
|
.Ar spi
|
|
from a
|
|
.Ar source
|
|
to a
|
|
.Ar destination ,
|
|
using a particular
|
|
.Ar transform
|
|
and
|
|
.Ar key .
|
|
If a transform requires an initialization vector, the
|
|
.Ar iv
|
|
argument contains it. This command is available only in interactive mode
|
|
because
|
|
.Nm
|
|
makes no attempt to destroy its argument vector after use. A malicious user
|
|
of the
|
|
.Xr ps 1
|
|
command could determine security keys if
|
|
.Ic add
|
|
were allowed to be used straight from the command line. Example:
|
|
.Bd -literal
|
|
add esp 2112 temples.syrinx.org priests.syrinx.org des-cbc \\
|
|
a652a476a652a476 87ac9876deac9876
|
|
.Ed
|
|
.It Ic exit
|
|
.It Ic quit
|
|
.Pp
|
|
Exit interaction with
|
|
.Nm .
|
|
An EOF will also end interaction with
|
|
.Nm .

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
command first appeared in NRL's
|
|
.Bx 4.4
|
|
IPv6 networking distribution.
|
|
.Nm Keyadmin
|
|
started its life as a pipe dream thought up by Dan McDonald, and came to
|
|
life through the excruciating efforts of Ran Atkinson, Dan McDonald,
|
|
Craig Metz, and Bao Phan.
|
|
The NRL version of the program was originally called
|
|
.Nm key ,
|
|
but was renamed to
|
|
.Nm
|
|
because of the conflict with
|
|
.Xr key 1 .
|
|
.Sh BUGS
|
|
.Nm Keyadmin
|
|
needs a -n flag like
|
|
.Xr route 8
|
|
to avoid name lookups.
|
|
.Pp
|
|
The
|
|
.Ic dump
|
|
and
|
|
.Ic save
|
|
commands currently display the first 30 or so entries.
