This format consists of sections, each beginning with a line looking like: .Bd -literal [Section name] .Ed 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: .Bd -literal Tag=Value .Ed 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. .Pp Comments can be put anywhere in the file by using a hash mark .Pq Sq \&# . The comment extends to the end of the current line. .Pp 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 syntax, where X is a value we offer and Y:Z is a range of accepted values, inclusive. .Pp To activate changes to .Nm without restarting .Nm isakmpd , send a SIGHUP signal to the daemon process. .Ss Auto-generated parts of the configuration .Pp 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. .Pp For Main Mode: .Bd -filled -compact .Ar {DES,BLF,3DES,CAST}-{MD5,SHA}[-GRP{1,2,5}][-{DSS,RSA_SIG}] .Ed .Pp For Quick Mode: .Bd -filled -compact .Ar QM-{proto}[-TRP]-{cipher}[-{hash}][-PFS[-{group}]]-SUITE .Ed .Bd -literal where {proto} is either ESP or AH {cipher} is either DES, 3DES, CAST, BLF or AES {hash} is either MD5, SHA or RIPEMD {group} is either GRP1, GRP2 or GRP5 .Ed .Pp For example, 3DES-SHA means: 3DES encryption, SHA hash, and authorization by pre-shared keys. Similarly, QM-ESP-3DES-SHA-PFS-SUITE means: ESP protocol, 3DES encryption, SHA hash, and use Perfect Forward Security. .Pp Unless explicitly stated with -GRP1, 2 or 5, transforms and PFS suites use DH group 2. There are currently no predefined ESP+AH Quick Mode suites. .Pp 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. .Pp 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) lifetimes can be overridden by these tags under the "General" section; .Pp .Bd -literal [General] Default-phase-1-lifetime= 3600,60:86400 Default-phase-2-lifetime= 1200,60:86400 .Ed .Pp 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). .\"XXX Following empty .Ss works around a nroff bug, we want the new line." .Ss .Pp Also, the default phase 1 ID can be set by creating a section, as shown below, and adding this tag under the "General" section; .Pp .Bd -literal [General] Default-phase-1-ID= Phase1-ID-name [Phase1-ID-name] ID-type= USER_FQDN Name= foo@bar.com .Ed .\"XXX Following empty .Ss works around a nroff bug, we want the new line." .Ss .Pp .Ss Roots .Bl -hang -width 12n .It Em General Generic global configuration parameters .Bl -tag -width 12n .It Em Default-phase-1-ID Optional default phase 1 ID name. .It Em Default-phase-1-lifetime The default lifetime for autogenerated transforms (phase 1). If unspecified, the value 3600,60:86400 is used as the default. .It Em Default-phase-2-lifetime The default lifetime for autogenerated suites (phase 2). If unspecified, the value 1200,60:86400 is used as the default. .It Em Default-phase-2-suites A list of phase 2 suites that will be used when establishing dynamic SAs. If left unspecified, QM-ESP-3DES-SHA-PFS-SUITE is used as the default. .It Em Check-interval The interval between watchdog checks of connections we want up at all times. .It Em Exchange-max-time How many seconds should an exchange maximally take to set up before we give up. .It Em Listen-on A list of IP-addresses OK to listen on. This list is used as a filter for the set of addresses the interfaces configured provides. This means that we won't see if an address given here does not exist on this host, and thus no error is given for that case. .It Em Policy-file The name of the file that contains .Xr keynote 4 policies. The default is "/etc/isakmpd/isakmpd.policy". .It Em Pubkey-directory The directory in which .Nm looks for explicitly trusted public keys. The default is "/etc/isakmpd/pubkeys". Read .Xr isakmpd 8 for the required naming convention of the files in here. .It Em Retransmits How many times should a message be retransmitted before giving up. .It Em Shared-SADB If this tag is defined, whatever the value is, some semantics of .Nm are changed so that multiple instances can run on top of one SADB and set up SAs with each other. Specifically this means replay protection will not be asked for, and errors that can occur when updating an SA with its parameters a 2nd time will be ignored. .El .It Em Phase 1 ISAKMP SA negotiation parameter root .Bl -tag -width 12n .It Em A name of the ISAKMP peer at the given IP-address. .It Em Default A name of the default ISAKMP peer. Incoming phase 1 connections from other IP-addresses will use this peer name. .It "" This name is used as the section name for further information to be found. Look at below. .El .It Em Phase 2 IPsec SA negotiation parameter root .Bl -tag -width 12n .It Em 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 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 section, in the "Flags" tag. .It Em Passive-connections A list of IPsec "connection" names we recognize and accept initiations for. These names are section names where further information can be found. Look at 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 initiator. .El .It Em KeyNote .Bl -tag -width 12n .It Em Credential-directory A directory containing directories named after IDs (IP addresses, ``user@domain'', or hostnames) that contain files named ``credentials'' and ``private_key''. .Pp The credentials file contains .Xr keynote 4 credentials that are sent to a remote IKE daemon when we use the associated ID, or credentials that we may want to consider 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 policy file). The credentials are of the same format as the policies described in .Xr isakmpd.policy 5 . The only difference is that the Authorizer field contains a public key, and the assertion is signed. Signed assertions can be generated using the .Xr keynote 1 utility. .Pp 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 authentication. .El .It Em X509-Certificates .Bl -tag -width 12n .It Em Accept-self-signed If this tag is defined, whatever the value is, certificates that do not originate from a trusted CA but are self-signed will be accepted. .It Em Ca-directory A directory containing PEM certificates of certification authorities that we trust to sign other certificates. Note that for a CA to be really trusted, it needs to be somehow referred to by policy, in .Xr 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) allows for maintenance of a list of "well known" CAs without actually having to trust all (or any) of them. .It Em 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, as provided by .Xr certpatch 8 . .It Em Private-key The private key matching the public key of our certificate (which should be in the "Cert-directory", and have an appropriate subjectAltName field). .El .El .Ss Referred-to sections .Bl -hang -width 12n .It Em Parameters for negotiation with an ISAKMP peer .Bl -tag -width 12n .It Em Phase The constant .Li 1 , as ISAKMP-peers and IPsec-connections really are handled by the same code inside isakmpd. .It Em Transport The name of the transport protocol, defaults to .Li UDP . .It Em Port In case of .Li UDP , the .Li UDP port number to send to. This is optional, the default value is 500 which is the IANA-registered number for ISAKMP. .It Em Local-address The Local IP-address to use, if we are multi-homed, or have aliases. .It Em Address If existent, the IP-address of the peer. .It Em Configuration The name of the ISAKMP-configuration section to use. Look at below. If unspecified, defaults to "Default-phase-1-configuration". .It Em Authentication If existent, authentication data for this specific peer. In the case of preshared key, this is the key value itself. .It Em 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 interface we are sending packets over to the remote daemon. Look at below. .It Em 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 below. .It Em Flags A comma-separated list of flags controlling the further handling of the ISAKMP SA. Currently there are no specific ISAKMP SA flags defined. .El .It Em .Bl -tag -width 12n .It Em ID-type The ID type as given by the RFC specifications. For phase 1 this is currently .Li IPV4_ADDR , .Li IPV4_ADDR_SUBNET , .Li IPV6_ADDR , .Li IPV6_ADDR_SUBNET , .Li FQDN , .Li USER_FQDN or .Li KEY_ID . .It Em Address If the ID-type is .Li IPV4_ADDR or .Li IPV6_ADDR , this tag should exist and be an IP-address. .It Em Network If the ID-type is .Li IPV4_ADDR_SUBNET or .Li IPV6_ADDR_SUBNET this tag should exist and be a network address. .It Em Netmask If the ID-type is .Li IPV4_ADDR_SUBNET or .Li IPV6_ADDR_SUBNET this tag should exist and be a network subnet mask. .It Em Name If the ID-type is .Li FQDN , .Li USER_FQDN or .Li KEY_ID , this tag should exist and contain a domain name, user@domain, or other identifying string respectively. .Pp In the case of .Li KEY_ID , note that the IKE protocol allows any octet sequence to be sent or received under this payload, potentially including non-printable ones. .Xr isakmpd 8 can only transmit printable .Li KEY_ID payloads, but can receive and process arbitrary .Li KEY_ID payloads. This effectively means that non-printable .Li KEY_ID remote identities cannot be verified through this means, although it is still possible to do so through .Xr isakmpd.policy 5 . .El .It Em .Bl -tag -width 12n .It Em DOI The domain of interpretation as given by the RFCs. Normally .Li IPSEC . If unspecified, defaults to .Li IPSEC . .It Em EXCHANGE_TYPE The exchange type as given by the RFCs. For main mode this is .Li ID_PROT and for aggressive mode it is .Li AGGRESSIVE . .It Em Transforms A list of proposed transforms to use for protecting the ISAKMP traffic. These are actually names for sections further describing the transforms. Look at below. .El .It Em .Bl -tag -width 12n .It Em ENCRYPTION_ALGORITHM The encryption algorithm as the RFCs name it, or ANY to denote that any encryption algorithm proposed will be accepted. .It Em KEY_LENGTH For encryption algorithms with variable key length, this is where the offered/accepted keylengths are described. The value is of the offer-accept kind described above. .It Em HASH_ALGORITHM The hash algorithm as the RFCs name it, or ANY. .It Em AUTHENTICATION_METHOD The authentication method as the RFCs name it, or ANY. .It Em GROUP_DESCRIPTION The group used for Diffie-Hellman exponentiations, or ANY. The names are symbolic, like .Li MODP_768 , MODP_1024 , EC_155 and .Li EC_185 . .It Em PRF The algorithm to use for the keyed pseudo-random function (used for key derivation and authentication in phase 1), or ANY. .It Em 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 below. If it is set to ANY, then any type of proposed lifetime type and value will be accepted. .El .It Em .Bl -tag -width 12n .It Em LIFE_TYPE .Li SECONDS or .Li KILOBYTES depending on the type of the duration. Notice that this field may NOT be set to ANY. .It Em LIFE_DURATION An offer/accept kind of value, see above. Can also be set to ANY. .El .It Em .Bl -tag -width 12n .It Em Phase The constant .Li 2 , as ISAKMP-peers and IPsec-connections really are handled by the same code inside isakmpd. .It Em ISAKMP-peer The name of the ISAKMP-peer which to talk to in order to set up this connection. The value is the name of an section. See above. .It Em Configuration The name of the IPsec-configuration section to use. Look at below. .It Em 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 we are dealing with. Look at below. .It Em 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 we are dealing with. Look at below. .It Em Flags A comma-separated list of flags controlling the further handling of the IPsec SA. Currently only one flag is defined: .Bl -tag -width 12n .It Em Active-only If this flag is given and this is part of the phase 2 connections we automatically keep up, it will not automatically be used for accepting connections from the peer. .El .El .It Em .Bl -tag -width 12n .It Em DOI The domain of interpretation as given by the RFCs. Normally .Li IPSEC . If unspecified, defaults to .Li IPSEC . .It Em EXCHANGE_TYPE The exchange type as given by the RFCs. For quick mode this is .Li QUICK_MODE . .It Em 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 section. See below. .El .It Em .Bl -tag -width 12n .It Em Protocols A list of the protocols included in this protection suite. Each of the list elements is a name of an section. See below. .El .It Em .Bl -tag -width 12n .It Em PROTOCOL_ID The protocol as given by the RFCs. Acceptable values today are .Li IPSEC_AH and .Li IPSEC_ESP . .It Em Transforms A list of transforms usable for implementing the protocol. Each of the list elements is a name of an section. See below. .It Em ReplayWindow The size of the window used for replay protection. This is normally left alone. Look at the .Nm ESP and .Nm AH RFCs for a better description. .El .It Em .Bl -tag -width 12n .It Em TRANSFORM_ID The transform ID as given by the RFCs. .It Em ENCAPSULATION_MODE The encapsulation mode as given by the RFCs. This means TRANSPORT or TUNNEL. .It Em AUTHENTICATION_ALGORITHM The optional authentication algorithm in the case of this being an ESP transform. .It Em GROUP_DESCRIPTION An optional (provides PFS if present) Diffie-Hellman group description. The values are the same as GROUP_DESCRIPTION's in sections shown above. .It Em Life List of lifetimes, each element is a section name. .El .It Em .Bl -tag -width 12n .It Em ID-type The ID type as given by the RFCs. For IPsec this is currently .Li IPV4_ADDR , .Li IPV6_ADDR , .Li IPV4_ADDR_SUBNET or .Li IPV6_ADDR_SUBNET . .It Em Address If the ID-type is .Li IPV4_ADDR or .Li IPV6_ADDR this tag should exist and be an IP-address. .It Em Network If the ID-type is .Li IPV4_ADDR_SUBNET or .Li IPV6_ADDR_SUBNET this tag should exist and be a network address. .It Em Netmask If the ID-type is .Li IPV4_ADDR_SUBNET or .Li IPV6_ADDR_SUBNET this tag should exist and be a network subnet mask. .It Em Protocol If the ID-type is .Li IPV4_ADDR , .Li IPV4_ADDR_SUBNET , .Li IPV6_ADDR or .Li IPV6_ADDR_SUBNET this tag indicates what transport protocol should be transmitted over the SA. If left unspecified, all transport protocols between the two address (ranges) will be sent (or permitted) over that SA. .It Em Port If the ID-type is .Li IPV4_ADDR , .Li IPV4_ADDR_SUBNET , .Li IPV6_ADDR or .Li 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 protocol will be transmitted (or permitted) over the SA. The Protocol tag must be specified in conjunction with this tag. .El .El .Ss Other sections .Bl -hang -width 12n .It Em Parameters to use with IKE mode-config. One ID per peer. .Pp An IKECFG-ID is written as [/]. The following ID types are supported: .Bl -tag -width 12n .It IPv4 [ipv4/A.B.C.D] .It IPv6 [ipv6/abcd:abcd::ab:cd] .It FQDN [fqdn/foo.bar.org] .It UFQDN [ufqdn/user@foo.bar.org] .It ASN1_DN [asn1_dn//C=aa/O=cc/...] (Note the double slashes as the DN itself starts with a '/'.) .El .Pp Each section specifies what configuration values to return to the peer requesting IKE mode-config. Currently supported values are: .Bl -tag -width 12n .It Em Address The peer's network address. .It Em Netmask The peer's netmask. .It Em Nameserver The IP address of a DNS nameserver. .It Em WINS-server The IP address of a WINS server. .El .It Em .Pp During phase 1 negotiation .Nm isakmpd looks for a pre-shared key in the section. If no Authentication data is specified in that section, and .Nm isakmpd 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. .Pp This only works for aggressive mode because in main mode the remote initiator ID would not yet be known. .Pp The name of the section depends on the ID type sent by the initiator. Currently this can be: .Bl -tag -width 12n .It IPv4 [A.B.C.D] .It IPv6 [abcd:abcd::ab:cd] .It FQDN [foo.bar.org] .It UFQDN [user@foo.bar.org] .El .El .Sh EXAMPLES An example of a configuration file: .Pp .Bd -literal # A configuration sample for the isakmpd ISAKMP/Oakley (aka IKE) daemon.
