ike.config \- configuration file for IKE policy
.SH SYNOPSIS
.LP
.nf
\fB/etc/inet/ike/config\fR
.fi

.SH DESCRIPTION
.sp
.LP
The \fB/etc/inet/ike/config\fR file contains rules for matching inbound IKE
requests. It also contains rules for preparing outbound \fBIKE\fR requests.
.sp
.LP
You can test the syntactic correctness of an \fB/etc/inet/ike/config\fR file by
using the \fB-c\fR or \fB-f\fR options of \fBin.iked\fR(1M). You must use the
\fB-c\fR option to test a \fBconfig\fR file. You might need to use the \fB-f\fR
option if it is not in \fB/etc/inet/ike/config\fR.
.SS "Lexical Components"
.sp
.LP
On any line, an unquoted \fB#\fR character introduces a comment. The remainder
of that line is ignored. Additionally, on any line, an unquoted \fB//\fR
sequence introduces a comment. The remainder of that line is ignored.

There are several types of lexical tokens in the \fBike.config\fR file:
.sp

.mk
.na
\fB\fIIPaddr\fR/\fIprefix\fR/\fIrange\fR\fR
.ad
.sp .6
.RS 4n
An IPv4 or IPv6 address with an optional /\fINNN\fR suffix, (where \fINNN\fR is
a \fInum\fR) that indicates an address (\fBCIDR\fR) prefix (for example,
\fB10.1.2.0/24\fR). An optional /\fIADDR\fR suffix (where \fIADDR\fR is a
second IP address) indicates an address/mask pair (for example,
\fB10.1.2.0/255.255.255.0\fR). An optional -\fIADDR\fR suffix (where \fIADDR\fR
is a second IPv4 address) indicates an inclusive range of addresses (for
example, \fB10.1.2.0-10.1.2.255\fR). The \fB/\fR or \fB-\fR can be surrounded
by an arbitrary amount of white space.

\fB\fIcert-sel\fR\fR
.ad
.sp .6
.RS 4n
A certificate selector, a \fIstring\fR which specifies the identities of zero
or more certificates. The specifiers can conform to \fBX.509\fR naming
conventions.
.sp
A \fIcert-sel\fR can also use various shortcuts to match either subject
alternative names, the filename or \fBslot\fR of a certificate in
\fB/etc/inet/ike/publickeys\fR, or even the \fBISSUER\fR. For example:
.sp
.in +2
.nf
"SLOT=0" 
"EMAIL=postmaster@domain.org" 
"webmaster@domain.org" # Some just work w/o TYPE=
"IP=10.0.0.1"
"10.21.11.11"          # Some just work w/o TYPE=
"DNS=www.domain.org"
"mailhost.domain.org"  # Some just work w/o TYPE=
"ISSUER=C=US, O=Sun Microsystems\\, Inc., CN=Sun CA"
.fi
.in -2
.sp

Any \fIcert-sel\fR preceded by the character \fB!\fR indicates a negative
match, that is, not matching this specifier. These are the same kind of strings
used in \fBikecert\fR(1M).

The string that follows is a name of a shared object (\fB\&.so\fR) that
implements the PKCS#11 standard. The name is passed directly into
\fBdlopen\fR(3C) for linking, with all of the semantics of that library call.
By default, \fBin.iked\fR(1M) runs the same ISA as the running kernel, so a
library specified using \fBpkcs11_path\fR and an absolute pathname \fBmust\fR
match the same ISA as the kernel. One can use the start/exec SMF property (see
\fBsvccfg\fR(1M)) to change \fBin.iked\fR's ISA, but it is not recommended.
.sp
If this setting is not present, the default value is set to \fBlibpkcs11.so\fR.
Most cryptographic providers go through the default library, and this parameter
should only be used if a specialized provider of IKE-useful cryptographic
services cannot interface with the Solaris Cryptographic Framework. See

.sp .6
.RS 4n
An encryption algorithm, as in \fBipsecconf\fR(1M). However, of the ciphers
listed above, only \fBaes\fR and \fBaes-cbc\fR allow optional key-size setting,
using the "low value-to-high value" syntax. To specify a single AES key size,
the low value must equal the high value. If no range is specified, all three
AES key sizes are allowed.

### BEGINNING OF FILE

### First some global parameters...

### certificate parameters...

# Root certificates. I SHOULD use a full Distinguished Name.
# I must have this certificate in my local filesystem, see ikecert(1m).
cert_root    "C=US, O=Sun Microsystems\\, Inc., CN=Sun CA"

# Explicitly trusted certs that need no signatures, or perhaps 
# self-signed ones. Like root certificates, use full DNs for them 
# for now.
cert_trust    "EMAIL=root@domain.org"

# Where do I send LDAP requests?
ldap_server        "ldap1.domain.org,ldap2.domain.org:389"

## phase 1 transform defaults...

p1_lifetime_secs 14400
p1_nonce_len 20

## Parameters that might also show up in rules.
