NAME

     isakmpd.conf - configuration file for isakmpd

DESCRIPTION

     isakmpd.conf is the configuration file for the isakmpd(8) daemon, manag-
     ing security association and key management for the IPsec layer of the
     kernel's networking stack.

     The file is of a well known type of format called .INI style, named after
     the suffix used by an overrated windowing environment for its configura-
     tion files. This format consists of sections, each beginning with a line
     looking like:

     [Section name]
     Between the brackets is the name of the section following this section
     header. Inside a section many tag/value pairs can be stored, each one
     looking like:

     Tag=Value
     If the value needs more space than fits on a single line, it's possible
     to continue it on the next by ending the first with a backslash character
     immediately before the newline character. This method can extend a value
     for an arbitrary number of lines.

     Comments can be put anywhere in the file by using a hash mark ('#'). The
     comment extends to the end of the current line.

     Often the right-hand side values consist of other section names. This
     results in a tree structure. Some values are treated as a list of several
     scalar values. Such lists always use a comma character as the separator.
     Some values are formatted like this: X,Y:Z, which is an offer/accept syn-
     tax, where X is a value we offer and Y:Z is a range of accepted values,
     inclusive.

     To activate changes to isakmpd.conf without restarting isakmpd(8), send a
     SIGHUP signal to the daemon process.

AUTO-GENERATED PARTS OF THE CONFIGURATION
     Some predefined section names are recognized by the daemon, avoiding the
     need to fully specify the Main Mode transforms and Quick Mode suites,
     protocols, and transforms.

     For Main Mode:
     {DES,BLF,3DES,CAST,AES}-{MD5,SHA}[-GRP{1,2,5,14}][-{DSS,RSA_SIG}]

     For Quick Mode:
     QM-{proto}[-TRP]-{cipher}[-{hash}][-PFS[-{group}]]-SUITE

     where:
           {proto}   is either ESP or AH
           {cipher}  is either DES, 3DES, CAST, BLF, or AES
           {hash}    is either MD5, SHA, RIPEMD, or SHA2-{256,384,512}
           {group}   is either GRP1, GRP2, GRP5, or GRP14

     For example, 3DES-SHA means: 3DES encryption, SHA hash, and authorization
     by pre-shared keys. Similarly, QM-ESP-3DES-SHA-PFS-SUITE means: ESP pro-
     tocol, 3DES encryption, SHA hash, and use Perfect Forward Secrecy.

     Unless explicitly stated with -GRP1, 2, 5, or 14, transforms and PFS
     suites use DH group 2. There are currently no predefined ESP+AH Quick
     Mode suites.

     The predefinitions include some default values for the special sections
     "General", "Keynote", "X509-certificates", and "Default-phase-1-
     configuration". These default values are presented in the example below.

     All autogenerated values can be overridden by manual entries by using the
     same section and tag names in the configuration file. In particular, the
     default phase 1 (Main or Aggressive Mode) and phase 2 (Quick Mode) life-
     times can be overridden by these tags under the "General" section:

           [General]
           Default-phase-1-lifetime=       3600,60:86400
           Default-phase-2-lifetime=       1200,60:86400

     The Main Mode lifetime currently defaults to one hour (minimum 60
     seconds, maximum 1 day). The Quick Mode lifetime defaults to 20 minutes
     (minimum 60 seconds, maximum 1 day).

     Also, the default phase 1 ID can be set by creating a <Phase1-ID> sec-
     tion, as shown below, and adding this tag under the "General" section:

           [General]
           Default-phase-1-ID=             Phase1-ID-name

           [Phase1-ID-name]
           ID-type=                        USER_FQDN
           Name=                           foo@bar.com

ROOTS

     [General] Generic global configuration parameters

               Acquire-Only
                       If this tag is defined, isakmpd(8) will not set up
                       flows automatically. This is useful when flows are con-
                       figured with ipsecadm(8) or by other programs like
                       bgpd(8). Thus isakmpd(8) only takes care of the SA es-
                       tablishment.

               Check-interval
                       The interval between watchdog checks of connections we
                       want up at all times, in seconds. The default value is
                       60 seconds.

               Default-phase-1-ID
                       Optional default phase 1 ID name.

               Default-phase-1-lifetime
                       The default lifetime for autogenerated transforms
                       (phase 1). If unspecified, the value 3600,60:86400 is
                       used as the default.

               Default-phase-2-lifetime
                       The default lifetime for autogenerated suites (phase
                       2). If unspecified, the value 1200,60:86400 is used as
                       the default.

               Default-phase-2-suites
                       A list of phase 2 suites that will be used when estab-
                       lishing dynamic SAs. If left unspecified, QM-ESP-3DES-
                       SHA-PFS-SUITE is used as the default.

               DPD-check-interval
                       The interval between RFC 3706 (Dead Peer Detection)
                       messages, in seconds. The default value is 0 (zero),
                       which means DPD is disabled.

               Exchange-max-time
                       How many seconds should an exchange maximally take to
                       set up before we give up.

               Listen-on
                       A list of IP addresses or interface names OK to listen
                       on. This list is used as a filter for the set of ad-
                       dresses the interfaces configured provides. This means
                       that we won't see if an address given here does not ex-
                       ist on this host, and thus no error is given for that
                       case.

               Loglevel
                       A list of the form class=level, where both class and
                       level are numbers. This is similar to the -D command
                       line switch of isakmpd(8).

               Logverbose
                       If this tag is defined, whatever the value is, verbose
                       logging is enabled. This is similar to the -v command
                       line switch of isakmpd(8).

               NAT-T-Keepalive
                       The number of seconds between NAT-T keepalive messages,
                       sent by the peer behind NAT to keep the mapping active.
                       Defaults to 20.

               Policy-file
                       The name of the file that contains keynote(4) policies.
                       The default is /etc/isakmpd/isakmpd.policy.

               Pubkey-directory
                       The directory in which isakmpd.conf looks for explicit-
                       ly trusted public keys. The default is
                       /etc/isakmpd/pubkeys. Read isakmpd(8) for the required
                       naming convention of the files in here.

               Renegotiate-on-HUP
                       If this tag is defined, whatever the value is,
                       isakmpd(8) will renegotiate all current phase 2 SAs
                       when the daemon receives a SIGHUP signal, or an 'R' is
                       sent to the FIFO interface (see isakmpd(8)).

               Retransmits
                       How many times should a message be retransmitted before
                       giving up.

               Shared-SADB
                       If this tag is defined, whatever the value is, some se-
                       mantics of isakmpd.conf are changed so that multiple
                       instances can run on top of one SADB and set up SAs
                       with each other. Specifically this means replay protec-
                       tion will not be asked for, and errors that can occur
                       when updating an SA with its parameters a 2nd time will
                       be ignored.

               Use-Keynote
                       This tag controls the use of keynote(4) policy check-
                       ing. The default value is "yes", which enables the pol-
                       icy checking. When set to any other value, policies
                       will not be checked. This is useful when policies for
                       flows and SA establishment are arranged by other pro-
                       grams like ipsecadm(8) or bgpd(8).

     [Phase 1] ISAKMP SA negotiation parameter root

               Default
                       A name of the default ISAKMP peer. Incoming phase 1
                       connections from other IP addresses will use this peer
                       name. This name is used as the section name for further
                       information to be found. Look at <ISAKMP-peer> below.

               <IP-address>
                       A name of the ISAKMP peer at the given IP address.

     [Phase 2] IPsec SA negotiation parameter root

               Connections
                       A list of directed IPsec "connection" names that should
                       be brought up automatically, either on first use if the
                       system supports it, or at startup of the daemon. These
                       names are section names where further information can
                       be found. Look at <IPsec-connection> below. Normally
                       any connections mentioned here are treated as part of
                       the "Passive-connection" list we present below; however
                       there is a flag, Active-only, that disables this
                       behaviour. This too is mentioned in the <IPsec-
                       connection> section, in the "Flags" tag.

               Passive-connections
                       A list of IPsec "connection" names we recognize and ac-
                       cept initiations for. These names are section names
                       where further information can be found. Look at
                       <IPsec-connection> below. Currently only the Local-ID
                       and Remote-ID tags are looked at in those sections, as
                       they are matched against the IDs given by the initia-
                       tor.

     [KeyNote] KeyNote configuration section

               Credential-directory
                       A directory containing directories named after IDs (IP
                       addresses, "user@domain", or hostnames) that contain
                       files named "credentials" and "private_key".

                       The credentials file contains keynote(4) credentials
                       that are sent to a remote IKE daemon when we use the
                       associated ID, or credentials that we may want to con-
                       sider when doing an exchange with a remote IKE daemon
                       that uses that ID. Note that, in the former case, the
                       last credential in the file MUST contain our public key
                       in its Licensees field. More than one credentials may
                       exist in the file. They are separated by whitelines
                       (the format is essentially the same as that of the pol-
                       icy file). The credentials are of the same format as
                       the policies described in isakmpd.policy(5). The only
                       difference is that the Authorizer field contains a pub-
                       lic key, and the assertion is signed. Signed assertions
                       can be generated using the keynote(1) utility.

                       The private_key file contains the private RSA key we
                       use for authentication. If the directory (and the
                       files) exist, they take precedence over X509-based au-
                       thentication.

     [X509-Certificates] X509-certificate configuration section

               Accept-self-signed
                       If this tag is defined, whatever the value is, certifi-
                       cates that do not originate from a trusted CA but are
                       self-signed will be accepted.

               Ca-directory
                       A directory containing PEM certificates of certifica-
                       tion authorities that we trust to sign other certifi-
                       cates. Note that for a CA to be really trusted, it
                       needs to be somehow referred to by policy, in
                       isakmpd.policy(5). The certificates in this directory
                       are used for the actual X.509 authentication and for
                       cross-referencing policies that refer to Distinguished
                       Names (DNs). Keeping a separate directory (as opposed
                       to integrating policies and X.509 CA certificates) al-
                       lows for maintenance of a list of "well known" CAs
                       without actually having to trust all (or any) of them.

               Cert-directory
                       A directory containing PEM certificates that we trust
                       to be valid. These certificates are used in preference
                       to those passed in messages and are required to have a
                       subjectAltName extension containing the certificate
                       holder identity; usually IP address, FQDN, or User
                       FQDN.

               Private-key
                       The private key matching the public key of our certifi-
                       cate (which should be in the "Cert-directory", and have
                       an appropriate subjectAltName field).

REFERRED-TO SECTIONS
     <ISAKMP-peer> Parameters for negotiation with an ISAKMP peer

             Address
                     If existent, the IP address of the peer.

             Authentication
                     If existent, authentication data for this specific peer.
                     In the case of a pre-shared key, this is the key value
                     itself.

             Configuration
                     The name of the ISAKMP-configuration section to use. Look
                     at <ISAKMP-configuration> below. If unspecified, defaults
                     to "Default-phase-1-configuration".

             Flags   A comma-separated list of flags controlling the further
                     handling of the ISAKMP SA. Currently there are no specif-
                     ic ISAKMP SA flags defined.

             ID      If existent, the name of the section that describes the
                     local client ID that we should present to our peer. If
                     not present, it defaults to the address of the local in-
                     terface we are sending packets over to the remote daemon.
                     Look at <Phase1-ID> below.

             Local-address
                     The Local IP address to use, if we are multi-homed, or
                     have aliases.

             Phase   The constant '1', as ISAKMP-peers and IPsec-connections
                     really are handled by the same code inside isakmpd(8).

             Port    For UDP, the UDP port number to send to. This is option-
                     al; the default value is 500 which is the IANA-registered
                     number for ISAKMP.

             Remote-ID
                     If existent, the name of the section that describes the
                     remote client ID we expect the remote daemon to send us.
                     If not present, it defaults to the address of the remote
                     daemon. Look at <Phase1-ID> below.

             Transport
                     The name of the transport protocol; defaults to UDP.

     <Phase1-ID> Parameters for Phase 1 negotiation

             Address
                     If the ID-type is IPV4_ADDR or IPV6_ADDR, this tag should
                     exist and be an IP address.

             ID-type
                     The ID type as given by the RFC specifications. For phase
                     1 this is currently IPV4_ADDR, IPV4_ADDR_SUBNET,
                     IPV6_ADDR, IPV6_ADDR_SUBNET, FQDN, USER_FQDN, or KEY_ID.

             Name    If the ID-type is FQDN, USER_FQDN, or KEY_ID, this tag
                     should exist and contain a domain name, user@domain, or
                     other identifying string respectively.

                     In the case of KEY_ID, note that the IKE protocol allows
                     any octet sequence to be sent or received under this pay-
                     load, potentially including non-printable ones.
                     isakmpd(8) can only transmit printable KEY_ID payloads,
                     but can receive and process arbitrary KEY_ID payloads.
                     This effectively means that non-printable KEY_ID remote
                     identities cannot be verified through this means,
                     although it is still possible to do so through
                     isakmpd.policy(5).

             Netmask
                     If the ID-type is IPV4_ADDR_SUBNET or IPV6_ADDR_SUBNET,
                     this tag should exist and be a network subnet mask.

             Network
                     If the ID-type is IPV4_ADDR_SUBNET or IPV6_ADDR_SUBNET,
                     this tag should exist and be a network address.

     <ISAKMP-configuration> Parameters for ISAKMP configuration

             DOI     The domain of interpretation as given by the RFCs. Nor-
                     mally IPSEC. If unspecified, defaults to IPSEC.

                     A list of proposed transforms to use for protecting the
                     ISAKMP traffic. These are actually names for sections
                     further describing the transforms. Look at <ISAKMP-
                     transform> below.

                     The value is of the offer-accept kind described above.

             Life    A list of lifetime descriptions, or ANY. In the former
                     case, each element is in itself a name of the section
                     that defines the lifetime. Look at <Lifetime> below. If
                     it is set to ANY, then any type of proposed lifetime type
                     and value will be accepted.

             PRF     The algorithm to use for the keyed pseudo-random function

             Flags   A comma-separated list of flags controlling the further
                     handling of the IPsec SA. Currently only one flag is de-
                     fined:

                     Active-only
                          If this flag is given and this <IPsec-connection> is
                          part of the phase 2 connections we automatically
                          keep up, it will not automatically be used for ac-
                          cepting connections from the peer.

             ISAKMP-peer
                     The name of the ISAKMP-peer to talk to in order to set up
                     this connection. The value is the name of an <ISAKMP-
                     peer> section. See above.

             Local-ID
                     If existent, the name of the section that describes the
                     optional local client ID that we should present to our
                     peer. It is also used when we act as responders to find
                     out what <IPsec-connection> we are dealing with. Look at
                     <IPsec-ID> below.

             Phase   The constant '2', as ISAKMP-peers and IPsec-connections
                     really are handled by the same code inside isakmpd(8).

             Remote-ID
                     If existent, the name of the section that describes the
                     optional remote client ID that we should present to our
                     peer. It is also used when we act as responders to find
                     out what <IPsec-connection> we are dealing with. Look at
                     <IPsec-ID> below.

     <IPsec-configuration> Parameters for IPsec configuration

             DOI     The domain of interpretation as given by the RFCs. Nor-
                     mally IPSEC. If unspecified, defaults to IPSEC.

             EXCHANGE_TYPE
                     The exchange type as given by the RFCs. For quick mode
                     this is QUICK_MODE.

             Suites  A list of protection suites (bundles of protocols) usable
                     for protecting the IP traffic. Each of the list elements
                     is a name of an <IPsec-suite> section. See below.

     <IPsec-suite> Parameters for IPsec protection suite configuration

             Protocols
                     A list of the protocols included in this protection
                     suite. Each of the list elements is a name of an <IPsec-
                     protocol> section. See below.

     <IPsec-protocol> Parameters for IPsec protocol configuration

             PROTOCOL_ID
                     The protocol as given by the RFCs. Acceptable values are

             ReplayWindow
                     The size of the window used for replay protection. This
                     is normally left alone. Look at the ESP and AH RFCs for a
                     better description.

             Transforms
                     A list of transforms usable for implementing the proto-
                     col. Each of the list elements is a name of an <IPsec-

                     above.

             Life    List of lifetimes, each element is a <Lifetime> section
                     name.

             TRANSFORM_ID
                     The transform ID as given by the RFCs.

     <IPsec-ID> Parameters for IPsec ID configuration

             Address
                     If the ID-type is IPV4_ADDR or IPV6_ADDR, this tag should
                     exist and be an IP address, an interface name, or the
                     default keyword. If an interface is used, the first ad-
                     dress of the appropriate family will be used. The default
                     keyword uses the interface associated with the default
                     route. In the case of IPv6, link-local addresses will be
                     skipped if addresses which are not link-local exist. If
                     the address on the interface changes isakmpd(8) will not
                     track the change. The configuration must be reloaded to
                     learn the new address.

             ID-type
                     The ID type as given by the RFCs. For IPsec this is
                     currently IPV4_ADDR, IPV6_ADDR, IPV4_ADDR_SUBNET, or
                     IPV6_ADDR_SUBNET.

             Netmask
                     If the ID-type is IPV4_ADDR_SUBNET or IPV6_ADDR_SUBNET,
                     this tag should exist and be a network subnet mask or an
                     interface. When an interface is specified, the netmask is
                     the mask associated with the Network. The default keyword
                     uses the interface associated with the default route.

             Network
                     If the ID-type is IPV4_ADDR_SUBNET or IPV6_ADDR_SUBNET,
                     this tag should exist and be a network address, an inter-
                     face, or the default keyword. When an interface is speci-
                     fied, the network is selected as with the Address tag.

             Port    If the ID-type is IPV4_ADDR, IPV4_ADDR_SUBNET, IPV6_ADDR,
                     or IPV6_ADDR_SUBNET, this tag indicates what source or
                     destination port is allowed to be transported over the SA
                     (depending on whether this is a local or remote ID). If
                     left unspecified, all ports of the given transport proto-
                     col will be transmitted (or permitted) over the SA. The
                     Protocol tag must be specified in conjunction with this
                     tag.

             Protocol
                     If the ID-type is IPV4_ADDR, IPV4_ADDR_SUBNET, IPV6_ADDR,
                     or IPV6_ADDR_SUBNET, this tag indicates what transport
                     protocol should be transmitted over the SA. If left un-
                     specified, all transport protocols between the two ad-
                     dress (ranges) will be sent (or permitted) over that SA.

OTHER SECTIONS

     <IKECFG-ID> Parameters to use with IKE mode-config. One ID per peer.

               An IKECFG-ID is written as [<ID-type>/<name>]. The following ID
               types are supported:

                     IPv4       [ipv4/A.B.C.D]
                     IPv6       [ipv6/abcd:abcd::ab:cd]
                     FQDN       [fqdn/foo.bar.org]
                     UFQDN      [ufqdn/user@foo.bar.org]
                     ASN1_DN    [asn1_dn//C=aa/O=cc/...] (Note the double
                                slashes as the DN itself starts with a '/'.)

               Each section specifies what configuration values to return to
               the peer requesting IKE mode-config. Currently supported values
               are:

                     Address        The peer's network address.
                     Netmask        The peer's netmask.
                     Nameserver     The IP address of a DNS nameserver.
                     WINS-server    The IP address of a WINS server.

     <Initiator-ID> Parameters for peer initiator configuration

               During phase 1 negotiation isakmpd(8) looks for a pre-shared
               key in the <ISAKMP-peer> section. If no Authentication data is
               specified in that section, and isakmpd(8) is not the initiator,
               it looks for Authentication data in a section named after the
               initiator's phase 1 ID. This allows mobile users with dynamic
               IP addresses to have different shared secrets.

               This only works for aggressive mode because in main mode the
               remote initiator ID would not yet be known. Note, however, that
               use of aggressive mode is discouraged. See CAVEATS, below.

               The name of the <Initiator-ID> section depends on the ID type
               sent by the initiator. Currently this can be:

                     IPv4     [A.B.C.D]
                     IPv6     [abcd:abcd::ab:cd]
                     FQDN     [foo.bar.org]
                     UFQDN    [user@foo.bar.org]

FILES

     /etc/isakmpd/isakmpd.conf  The default isakmpd(8) configuration file.

     /usr/share/ipsec/isakmpd/  A directory containing some sample isakmpd(8)
                                configuration files.

CAVEATS

     Using aggressive mode is discouraged due to various design problems. If
     your peer only supports aggressive mode, please consider replacing that
     peer with a sane ISAKMP/IKE implementation. For details see
     http://www.usenix.org/publications/login/1999-12/features/harmful.html.

BUGS

     The RFCs do not permit differing DH groups in the same proposal for ag-
     gressive and quick mode exchanges. Mixing both PFS and non-PFS suites in
     a quick mode proposal is not possible, as PFS implies using a DH group.
