Platform Notes

Sun Solaris runs on SPARC and Intel hardware platforms.

Version History

Version Release Date Notes
Solaris 8 Feb 2000 First Solaris version to include IPsec. Manual keying only (no IKE)
Solaris 9 May 2002 IKE support added
Solaris 10 Jan 2005 NAT Traversal support added

IPsec support was first added in Solaris 8. IKE keying support was added in Solaris 9, using the in.iked daemon.

Backoff Patterns

All tested versions of Solaris (currently 9 and 10) have the six-packet IKE backoff pattern:

0, 0.5, 1, 2, 4, 8

Below is an example from Solaris 9 on SPARC. We need to specify a custom transform, as this system won't respond to our default transform set:

$ ike-scan -M --showbackoff --trans=5,1,1,5 192.168.124.158
Starting ike-scan 1.9 with 1 hosts (http://www.nta-monitor.com/tools/ike-scan/)
192.168.124.158 Main Mode Handshake returned
        HDR=(CKY-R=7e621cfe41000000)

IKE Backoff Patterns:

IP Address      No.     Recv time               Delta Time
192.168.124.158 1       1171722837.002113       0.000000

Here's an example from Solaris 10 on Intel IA-32, which shows the same backoff pattern:

$ ike-scan -M --trans=5,1,1,5 --showbackoff 172.16.3.28

Vendor IDs

Solaris 9 does not return any Vendor IDs.

Solaris 10 returns the following Vendor IDs indicating that it supports NAT Traversal:

  • RFC 3947 NAT-T (4a131c81070358455c5728f20e95452f)
  • RFC XXXX (810fa565f8ab14369105d706fbd57279)

Authentication Methods

Solaris supports four authentication types:

  • Pre-Shared Key
  • RSA Signature
  • RSA Encryption
  • DSS Signature

Pre-Shared Key and RSA Signature are common authentication methods. RSA Encryption and DSS Signature are standard methods, but are less commonly seen.

The syntax used in the /etc/inet/ike/config file is:

auth_method {preshared, rsa_sig, rsa_encrypt, dss_sig}

For authentication types other than Pre-Shared Key, a certificate is needed. In the examples in this document, the following command was used to generate a self-signed certificate on the Solaris 10 system named solaris10:

# ikecert certlocal -ks -m 1024 -t rsa-sha1 -D "C=GB, O=NTA_Monitor OU=Technical_Dept CN=solaris10"

Below are examples of each authentication method. In each case, the Phase-1 transform attributes other than authentication method are always Enc=DES, Hash=MD5, Group=1. For each example, we show the config file followed by the ike-scan output.

ISAKMP SA Lifetime

Lifetime in Seconds

Solaris 10 allows any lifetime in seconds including none at all. However, it does not support variable length attributes with a value length greater than four bytes even if the value is small enough to fit in four bytes.

For no lifetime at all, Solaris will not include any lifetime in its response. For any lifetime between zero and the maximum value that will fit in four bytes, Solaris will return that same lifetime.

Solaris also supports a lifetime in kilobytes, and handles it in exactly the same was as a lifetime in seconds.

Transform Attribute ordering and re-writing

Solaris generally returns the transform attributes in the order that they are supplied by the initiator.

In the example below, we specify the four mandatory transform attributes in order Enc, Hash, Auth, Group and then in reverse order Group, Auth, Hash, Enc, and observe that in both cases the target returns the attributes in the same order as the initiator specified them.

$ ike-scan -M --trans="(1=5,2=1,3=1,4=5)" 172.16.3.28

        VID=810fa565f8ab14369105d706fbd57279

Here is another example, this time including a lifetime in seconds, and a lifetime in kilobytes. Again, the attributes are returned in the same order that the initiator sent them.

Aggressive Mode

Sun Solaris supports IKE Aggressive Mode in addition to Main Mode.

Invalid Initiator Cookie

Solaris ignores an invalid cookie, or perhaps it considers a zero initiator cookie as valid. Note that the SPI in the SA uses the value from the initiator cookie.

NAT Traversal

Solaris 10 supports NAT Traversal. However, it does not respond to ike-scan with the --nat-t option because it uses source port 500 for the response packet rather than using the actual source port. Here is a tcpdump trace which shows this behaviour:

18:51:55.955646 IP 192.168.124.7.4500 > 172.16.3.28.4500: UDP, length: 88
18:51:55.980394 IP 172.16.3.28.500 > 192.168.124.7.4500: isakmp: phase 1 ? ident

It is not known if this constitutes a bug that prevents NAT Traversal working in real applications.

IVEv2

Sun Solaris does not support IKEv2 as of Solaris 10.

Remote Access VPN Client

There is no separate Remote Access VPN client for Solaris.

Other Interesting Behaviour

Last 24 bits of responder cookie is counter on Solaris 9

On Solaris 9, the last three bytes (24-bits) of the responder cookie are a counter. Below are twenty Solaris 9 responder cookies, sampled immediately after in.iked was restarted.

d805b9c006000011
33aeccd084000012
58a2c09d3a000013

The following command was used to obtain these responder cookie values:

perl -e 'print "192.168.124.158\n" x 20' | ike-scan -M --trans=5,1,1,5 -f -

This behaviour does not occur with Solaris 10, which has apparently random cookies. Below are ten cookies samples from Solaris 10 running on IA-32, obtained with a similar command:

3d49ae1f5533a10d

d3f993df7439d6a7

Solaris 9 uses responder cookie as SPI and Solaris 10 uses initiator cookie

Solaris 9 adds an 8-byte SPI with the same value as the responder cookie to the responder SA.

$ ike-scan -M --trans=5,1,1,5 192.168.124.158
Starting ike-scan 1.9 with 1 hosts (http://www.nta-monitor.com/tools/ike-scan/)

Solaris 10 also adds an 8-byte SPI, but it uses the initiator cookie instead.

Default Configuration

The IKE configuration is defined in the file /etc/inet/ike/config. If this file exists, then in.iked will start at boot time and use the configuration contained in it.

Solaris contains a sample file /etc/inet/ike/config.sample, which can be used as a template. This sample file is shown below.

In practice, most if not all users will need to customise this file, so there will be no such thing as a default configuration.

#
#ident  "@(#)config.sample      1.5     02/08/30 SMI"
#
# Copyright 2001-2002 Sun Microsystems, Inc.  All rights reserved.
# Use is subject to license terms.

##
## This file should be copied into /etc/inet/ike/config to enable the
## launch of the IKE daemon, in.iked(1m), at boot time.  You can also
## launch the IKE daemon after creating this file without rebooting by
## invoking /usr/lib/inet/in.iked with a root shell.
##

# Consult the ike.config(4) man page for further details.  Here is a small
# example from the man page.

### BEGINNING OF FILE

### First some global parameters...

## Optional hardware acceleration parameters...
## Use the pathname of a library that supports PKCS#11 in quotes.
## The example path is for the Sun Crypto Accelerator 1000.
# pkcs11_path "/opt/SUNWconn/lib/libpkcs11.so"

## 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"

# Some PKI-specific tweaks...
# If you wish to ignore CRLs, uncomment this:
#ignore_crls
# If you wish to use HTTP (with name resolution) for URLs inside certs,
# uncomment this:
#use_http
# HTTP proxy and socks URLs should also be indicated if needed...
socks "socks://socks-relay.domain.org"
#proxy "http://http-proxy.domain.org:8080"

## Phase 1 transform defaults...

p1_lifetime_secs 14400
p1_nonce_len 20

## Parameters that may also show up in rules.

p1_xform { auth_method preshared oakley_group 5 auth_alg sha encr_alg 3des }
p2_pfs 2

### Now some rules...

{
   label "simple inheritor"
   local_id_type ip
   local_addr 10.1.1.1
   remote_addr 10.1.1.2
}

{
   # an index-only rule.  If I'm a receiver, and all I
   # have are index-only rules, what do I do about inbound IKE requests?
   # Answer:  Take them all!

   label "default rule"
   # Use whatever "host" (e.g. IP address) identity is appropriate
   local_id_type ipv4

   local_addr 0.0.0.0/0
   remote_addr 0.0.0.0/0

   p2_pfs 5

   # Now I'm going to have the p1_xforms
   p1_xform
   {auth_method preshared  oakley_group 5  auth_alg md5  encr_alg blowfish }
   p1_xform
   {auth_method preshared  oakley_group 5  auth_alg md5  encr_alg 3des }

   # After said list, another keyword (or a '}') will stop xform parsing.
}

{
   # Let's try something a little more conventional.

   label "host to .80 subnet"
   local_id_type ip
   local_id "10.1.86.51"

   remote_id ""    # Take any, use remote_addr for access control.

   local_addr 10.1.86.51
   remote_addr 10.1.80.0/24

   p1_xform
   { auth_method rsa_sig  oakley_group 5  auth_alg md5  encr_alg 3des }
   p1_xform
   { auth_method rsa_sig  oakley_group 5  auth_alg md5  encr_alg blowfish }
   p1_xform
   { auth_method rsa_sig  oakley_group 5  auth_alg sha1  encr_alg 3des }
   p1_xform
   { auth_method rsa_sig  oakley_group 5  auth_alg sha1  encr_alg blowfish }
}
