ike.config

- configuration file for IKE policy

Synopsis

/etc/inet/ike/config

Description

The /etc/inet/ike/config file contains rules for matching inbound IKE requests. It also contains rules for preparing outbound IKE requests.

You can test the syntactic correctness of an /etc/inet/ike/config file by using the -c or -f options of in.iked(1M). You must use the -c option to test a config file. You might need to use the -f option if it is not in /etc/inet/ike/config.

Lexical Components

On any line, an unquoted # character introduces a comment. The remainder of that line is ignored. Additionally, on any line, an unquoted // sequence introduces a comment. The remainder of that line is ignored.

There are several types of lexical tokens in the ike.config file:

num

A decimal, hex, or octal number representation is as in C.

IPaddr/prefix/range

An IPv4 or IPv6 address with an optional /NNN suffix, (where NNN is a num) that indicates an address (CIDR) prefix (for example, 10.1.2.0/24). An optional /ADDR suffix (where ADDR is a second IP address) indicates an address/mask pair (for example, 10.1.2.0/255.255.255.0). An optional -ADDR suffix (where ADDR is a second IPv4 address) indicates an inclusive range of addresses (for example, 10.1.2.0-10.1.2.255). The / or - can be surrounded by an arbitrary amount of white space.

XXX | YYY | ZZZ

Either the words XXX, YYY, or ZZZ, for example, {yes,no}.

p1-id-type

An IKE phase 1 identity type. IKE phase 1 identity types include:

dn, DN
dns, DNS
fqdn, FQDN
gn, GN
ip, IP
ipv4
ipv4_prefix
ipv4_range
ipv6
ipv6_prefix
ipv6_range
mbox, MBOX
user_fqdn

Not all phase 1 identity types are supported.

"string"

A quoted string.

Examples include:"Label foo", or "C=US, OU=Sun Microsystems\\, Inc., N=olemcd@eng.example.com"

A backslash (\) is an escape character. If the string needs an actual backslash, two must be specified.

cert-sel

A certificate selector, a string which specifies the identities of zero or more certificates. The specifiers can conform to X.509 naming conventions.

A cert-sel can also use various shortcuts to match either subject alternative names, the filename or slot of a certificate in /etc/inet/ike/publickeys, or even the ISSUER. For example:

"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"

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

ldap-list

A quoted, comma-separated list of LDAP servers and ports.

For example, "ldap1.example.com", "ldap1.example.com:389", "ldap1.example.com:389,ldap2.example.com".

The default port for LDAP is 389.

parameter-list

A list of parameters.

label

A sensitivity label, either as a quoted string containing a human-readable label or as a hexadecimal format internal text label. See labels(5) for more information.

For example, PUBLIC, 0x0002-08-08.

File Body Entries

There are four main types of entries:

The global parameter entries are as follows:

cert_root cert-sel

The X.509 distinguished name of a certificate that is a trusted root CA certificate.It must be encoded in a file in the /etc/inet/ike/publickeys directory. It must have a CRL in /etc/inet/ike/crls. Multiple cert_root parameters aggregate.

cert_trust cert-sel

Specifies an X.509 distinguished name of a certificate that is self-signed, or has otherwise been verified as trustworthy for signing IKE exchanges. It must be encoded in a file in /etc/inet/ike/publickeys. Multiple cert_trust parameters aggregate.

expire_timer integer

The number of seconds to let a not-yet-complete IKE Phase I (Main Mode) negotiation linger before deleting it. Default value: 300 seconds.

ignore_crls

If this keyword is present in the file, in.iked(1M) ignores Certificate Revocation Lists (CRLs) for root CAs (as given in cert_root)

ignore_ocsp

If this keyword is present in the file, in.iked ignores OCSP information in certificate X.509v3 extensions and does not query Certificate Authorities via OCSP.

label_aware

This keyword can only be used on systems where Trusted Extensions are enabled. If this keyword is present in the file, in.iked(1M) attaches sensitivity label extensions to security associations, consults the tnrhdb for information about the clearances of peers, and negotiates labels with label-aware peers. Several additional keywords modify the behavior of in.iked in label-aware mode.

ldap_server ldap-list

A list of LDAP servers to query for certificates. The list can be additive.

pkcs11_path string

The string that follows is a name of a shared object (.so) that implements the PKCS#11 standard. The name is passed directly into dlopen(3C) for linking, with all of the semantics of that library call. By default, in.iked(1M) runs the same ISA as the running kernel, so a library specified using pkcs11_path and an absolute pathname must match the same ISA as the kernel. One can use the start/exec SMF property (see svccfg(1M)) to change in.iked's ISA, but it is not recommended.

If this setting is not present, the default value is set to libpkcs11.so. 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 cryptoadm(1M).

This option is now deprecated, and might be removed in a future release.

proxy string

The string following this keyword must be a URL for an HTTP proxy, for example, http://proxy:8080.

retry_limit integer

The number of retransmits before any IKE negotiation or Dead Peer Detection (DPD) process is aborted. Default value: 5 times.

retry_timer_init integer or float

The initial interval (in seconds) between retransmits. This interval is doubled until the retry_timer_max value (see below) is reached. Default value: 0.5 seconds.

retry_timer_max integer or float

The maximum interval (in seconds) between retransmits. Used for both IKE and Dead Peer Detection (DPD). The doubling retransmit interval stops growing at this limit. Default value: 30 seconds.

This value is never reached with the default configuration. The longest interval is 8 (0.5 * 2 ^ (5 - 1)) seconds.

socks string

The string following this keyword must be a URL for a SOCKS proxy, for example, socks://socks-proxy.

use_http

If this keyword is present in the file, in.iked(1M) uses HTTP to retrieve Certificate Revocation Lists (CRLs).

wire_label inner wire_label label wire_label none label

This keyword can only be used if label_aware mode is selected and defines how IKE communicates with label-aware peers. wire_label inner reuses the inner label, and sends key management traffic as admin_low. wire_label label uses the specified label for key management traffic and uses that label as the outer label for all encrypted traffic. The label is attached to each packet as a CIPSO label. wire_label none label does not attach a CIPSO label to either key management traffic or traffic sent as a given SA, but otherwise treats the traffic as if it had the given label.

The following IKE phase 1 transform parameters can be prefigured using file-level defaults. Values specified within any given transform override these defaults.

The IKE phase 1 transform defaults are as follows:

p1_lifetime_secs num

The proposed default lifetime, in seconds, of an IKE phase 1 security association (SA).

p1_nonce_len num

The length in bytes of the phase 1 (main mode) nonce data. This cannot be specified on a per-rule basis.

The following IKE rule parameters can be prefigured using file-level defaults. Values specified within any given rule override these defaults, unless a rule cannot.

p2_lifetime_secs num

The proposed default lifetime, in seconds, of an IKE phase 2 security association (SA). This value is optional. If omitted, a default value is used.

p2_softlife_secs num

The soft lifetime of a phase 2 SA, in seconds. If this value is specified, the SA soft expires after the number of seconds specified by p2_softlife_secs. This causes in.iked to renegotiate a new phase 2 SA before the original SA expires.

This value is optional, if omitted soft expiry occurs after 90% of the lifetime specified by p2_lifetime_secs. The value specified by p2_softlife_secs is ignored if p2_lifetime_secs is not specified.

Setting p2_softlife_secs to the same value as p2_lifetime_secs disables soft expires.

p2_idletime_secs num

The idle lifetime of a phase 2 SA, in seconds. If the value is specified, the value specifies the lifetime of the SA, if the security association is not used before the SA is revalidated.

p2_lifetime_kb num

The lifetime of an SA can optionally be specified in kilobytes. This parameter specifies the default value. If lifetimes are specified in both seconds and kilobytes, the SA expires when either the seconds or kilobyte thresholds are passed.

p2_softlife_kb num

This value is the number of kilobytes that can be protected by an SA before a soft expire occurs (see p2_softlife_secs, above).

This value is optional. If omitted, soft expiry occurs after 90% of the lifetime specified by p2_lifetime_kb. The value specified by p2_softlife_kb is ignored if p2_lifetime_kb is not specified.

p2_nonce_len num

The length in bytes of the phase 2 (quick mode) nonce data. This cannot be specified on a per-rule basis.

local_id_type p1-id-type

The local identity for IKE requires a type. This identity type is reflected in the IKE exchange. It is needed because a single certificate can contain multiple values for use in IKE phase 1. The type can be one of the following:

  • an IP address (for example, 10.1.1.2)

  • DNS name, also known as FQDN (for example, test.domain.com)

  • MBOX, also known as USER_FQDN or RFC 822 name (for example, root@domain.com)

  • DN-A X.509 distinguished name (for example, C=US, O=Sun Microsystems\, Inc., CN=Sun Test cert)

p1_xform '{' parameter-list '}

A phase 1 transform specifies a method for protecting an IKE phase 1 exchange. An initiator offers up lists of phase 1 transforms, and a receiver is expected to only accept such an entry if it matches one in a phase 1 rule. There can be several of these, and they are additive. There must be either at least one phase 1 transform in a rule or a global default phase 1 transform list. In a configuration file without a global default phase 1 transform list and a rule without a phase, transform list is an invalid file. Unless specified as optional, elements in the parameter-list must occur exactly once within a given transform's parameter-list:

oakley_group number

The Oakley Diffie-Hellman group used for IKE SA key derivation. The group numbers are defined in RFC 2409, Appendix A, RFC 3526, RFC 4753, and RFC 5114. Acceptable values are currently:

1 (768-bit)
2 (1024-bit)
5 (1536-bit)
14 (2048-bit)
15 (3072-bit)
16 (4096-bit)
19 (256-bit ECP defined by RFC4753)
20 (384-bit ECP defined by RFC4753)
21 (521-bit ECP defined by RFC4753)
22 (1024-bit MODP defined by RFC5114)
23 (2048-bit MODP defined by RFC5114)
24 (2048-bit MODP defined by RFC5114)
25 (192-bit ECP defined by RFC5114)
26 (224-bit ECP defined by RFC5114)
encr_alg {3des, 3des-cbc, blowfish, blowfish-cdc, des, des-cbc, aes, aes-cbc}

An encryption algorithm.

The algorithm names without mode specification are all synonyms for the CBC modes, for example, aes-cbc and aes are the same.

Only aes/aes-cbc allows optional key-size setting, using the (low..high) syntax, the same as specified in ipsecconf(1M) for the keylen specifier. To specify a single AES key size, the low value must equal the high value or single number must be used. If no range is specified, all three AES key sizes are allowed.

auth_alg {md5, sha, sha1, sha256, sha384, sha512}

An authentication algorithm.

auth_method {preshared, rsa_sig, rsa_encrypt, dss_sig}

The authentication method used for IKE phase 1.

p1_lifetime_secs num

Optional. The lifetime for a phase 1 SA.

p2_lifetime_secs num

If configuring the kernel defaults is not sufficient for different tasks, this parameter can be used on a per-rule basis to set the IPsec SA lifetimes in seconds.

p2_pfs num

Use perfect forward secrecy for phase 2 (quick mode). If selected, the oakley group specified is used for phase 2 PFS. Acceptable values are the same as for the oakley_group parameter listed above.

An IKE rule starts with a right-curly-brace ({), ends with a left-curly-brace (}), and has the following parameters in between:

label string

Required parameter. The administrative interface to in.iked looks up phase 1 policy rules with the label as the search string. The administrative interface also converts the label into an index, suitable for an extended ACQUIRE message from PF_KEY - effectively tying IPsec policy to IKE policy in the case of a node initiating traffic. Only one label parameter is allowed per rule.

local_addr <IPaddr/prefix/range>

Required parameter. The local address, address prefix, or address range for this phase 1 rule. Multiple local_addr parameters accumulate within a given rule.

remote_addr <IPaddr/prefix/range>

Required parameter. The remote address, address prefix, or address range for this phase 1 rule. Multiple remote_addr parameters accumulate within a given rule.

local_id_type p1-id-type

Which phase 1 identity type to use for this rule. The supported p1-id-types are described in section for the global parameter local_id_type. Within a given rule, all phase 1 transforms must either use preshared or non-preshared authentication (they can not be mixed).

For rules with preshared authentication, the local_id_type parameter is optional, and defaults to IP. For rules which use non-preshared authentication, the local_id_type preshared authentication, the local_id_type parameter parameter is required. Multiple local_id_type parameters within a rule are not allowed.

For rules with preshared authentication, the local_id_type parameter is optional, and defaults to IP. For rules which use non-preshared authentication, the local_id_type parameter is required. Multiple local_id_type parameters within a rule are not allowed.

local_id cert-sel

Disallowed for preshared authentication method; required parameter for non-preshared authentication method. The local identity string or certificate selector. Only one local identity per rule is used, the first one stated.

remote_id cert-sel

Disallowed for preshared authentication method; required parameter for non-preshared authentication method. Selector for which remote phase 1 identities are allowed by this rule. Multiple remote_id parameters accumulate within a given rule. If a single empty string ("") is given, then this accepts any remote ID for phase 1. It is recommended that certificate trust chains or address enforcement be configured strictly to prevent a breakdown in security if this value for remote_id is used.

p2_lifetime_secs num

If configuring the kernel defaults is not sufficient for different tasks, this parameter can be used on a per-rule basis to set the IPsec SA lifetimes in seconds.

p2_pfs num

Use perfect forward secrecy for phase 2 (quick mode). If selected, the oakley group specified is used for phase 2 PFS. Acceptable values are:

0 (do not use Perfect Forward Secrecy for IPsec SAs)
1 (768-bit)
2 (1024-bit)
5 (1536-bit)
14 (2048-bit)
15 (3072-bit)
16 (4096-bit)
p1_xform { parameter-list }

A phase 1 transform specifies a method for protecting an IKE phase 1 exchange. An initiator offers up lists of phase 1 transforms, and a receiver is expected to only accept such an entry if it matches one in a phase 1 rule. There can be several of these, and they are additive. There must be either at least one phase 1 transform in a rule or a global default phase 1 transform list. A ike.config file without a global default phase 1transform list and a rule without a phase 1 transform list is an invalid file. Elements within the parameter-list; unless specified as optional, must occur exactly once within a given transform's parameter-list:

oakley_group number

The Oakley Diffie-Hellman group used for IKE SA key derivation. Acceptable values are currently:

1 (768-bit)
2 (1024-bit)
5 (1536-bit)
14 (2048-bit)
15 (3072-bit)
16 (4096-bit)
encr_alg {3des, 3des-cbc, blowfish, blowfish-cdc, des, des-cbc, aes, aes-cbc}

An encryption algorithm, as in ipsecconf(1M). However, of the ciphers listed above, only aes and aes-cbc 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.

auth_alg {md5, sha, sha1}

An authentication algorithm, as specified in ipseckey(1M).

auth_method {preshared, rsa_sig, rsa_encrypt, dss_sig}

The authentication method used for IKE phase 1.

multi_label

Optional. Useful only on systems with Trusted Extensions enabled. Override tnrhdb and assume peer is label-aware.

p1_lifetime_secs num

Optional. The lifetime for a phase 1 SA.

single_label

Optional. Useful only on systems with Trusted Extensions enabled. Override tnrhdb and assume peer is not label-aware.

Examples

Example 1 A Sample ike.config File

The following is an example of an ike.config file:

 
### 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"
