    racoon.conf

    
         racoon(8) negotiates security associations for itself (ISAKMP SA, or
         phase 1 SA) and for kernel IPsec (IPsec SA, or phase 2 SA).  The file
         consists of a sequence of directives and statements.  Each directive is
         composed by a tag and statements, enclosed by '{' and '}'.  Lines begin-
         ning with '#' are comments.
    
       Meta Syntax
         Keywords and special characters that the parser expects exactly are dis-
         played using this font.  Parameters are specified with this font.  Square
         brackets ('[' and ']') are used to show optional keywords and parameters.
         Note that you have to pay attention when this manual is describing port
         numbers.  The port number is always enclosed by '[' and ']'.  In this
         case, the port number is not an optional keyword.  If it is possible to
         omit the port number, the expression becomes [[port]].  The vertical bar
         ('|') is used to indicate a choice between optional parameters.  Paren-
         theses ('(' and ')') are used to group keywords and parameters when nec-
         essary.  Major parameters are listed below.
    
         number    means a hexadecimal or a decimal number.  The former must be
                   prefixed with '0x'.
         string
         path
         file      means any string enclosed in '"' (double quotes).
         address   means IPv6 and/or IPv4 address.
         port      means a TCP/UDP port number.  The port number is always
                   enclosed by '[' and ']'.
         timeunit  is one of following: sec, secs, second, seconds, min, mins,
                   minute, minutes, hour, hours.
    
       Privilege separation
         privsep { statements }
                 Specifies privilege separation parameters.  When enabled, these
                 enable racoon(8) to operate with an unprivileged instance doing
                 most of the work, while a privileged instance takes care of per-
                 forming the following operations as root: reading PSK and private
                 keys, launching hook scripts, and validating passwords against
                 system databases or against PAM.  Please note that using privi-
                 lege separation makes changes to the listen and paths sections
                 ignored upon configuration reloads.  A racoon(8) restart is
                 required if you want such changes to be taken into account.
    
                 user user;
                         The user to which the unprivileged instance of racoon(8),
                         should switch.  This can be a quoted user name or a
                         numeric UID.
                 group group;
                         The group the unprivileged instance of racoon(8), should
                         switch.  This can be a quoted group name or a numeric
                         GID.
                 chroot path;
                         A directory to which the unprivileged instance of
                         racoon(8) should chroot(2).  This directory should hold a
    
         account.
         path include path;
                 Specifies a path to include a file.  See File Inclusion.
         path pre_shared_key file;
                 Specifies a file containing pre-shared key(s) for various ID(s).
                 See Pre-shared key File.
         path certificate path;
                 racoon(8) will search this directory if a certificate or certifi-
                 cate request is received.  If you run with privilege separation,
                 racoon(8) will refuse to use a certificate stored outside of this
                 directory.
         path backupsa file;
                 Specifies a file to which SA information negotiated by racoon
                 should be stored.  racoon(8) will install SA(s) from the file
                 when started with the -B flag.  The file is growing because
                 racoon(8) simply adds SAs to it.  You should maintain the file
                 manually.
         path script path;
                 racoon(8) will search this directory for scripts hooks.  If you
                 run with privilege separation, racoon(8) will refuse to execute a
                 script stored outside of this directory.
         path pidfile file;
                 Specifies file where to store PID of process.  If path starts
                 with / it is treated as an absolute path.  Otherwise, it is
                 treated as a relative path to the VARRUN directory specified at
                 compilation time.  Default is racoon.pid.
    
       File Inclusion
         include file
                 Specifies other configuration files to be included.
    
       Timer Specification
         timer { statements }
                 This section specifies various timer values used by racoon.
    
                 counter number;
                         The maximum number of retries to send.  The default is 5.
                 interval number timeunit;
                         The interval to resend, in seconds.  The default time is
                         10 seconds.
                 persend number;
                         The number of packets per send.  The default is 1.
                 phase1 number timeunit;
                         The maximum time it should take to complete phase 1.  The
                         default time is 15 seconds.
                 phase2 number timeunit;
                         The maximum time it should take to complete phase 2.  The
                         default time is 10 seconds.
                 natt_keepalive number timeunit;
                         The interval between sending NAT-Traversal keep-alive
                         packets.  The default time is 20 seconds.  Set to 0s to
                         disable keep-alive packets.
                         UDP-encapsulated ESP traffic for NAT-Traversal.  If you
                         plan to use NAT-T, you should provide at least one
                         address with port 4500, which is specified by IANA.
                         There is no default.
                 strict_address;
                         Requires that all addresses for ISAKMP be bound.  This
                         statement will be ignored if you do not specify address
                         definitions.
                 When running in privilege separation mode, you need to restart
                 racoon(8) to have changes to the listen section taken into
                 account.
    
                 The listen section can also be used to specify the admin socket
                 mode and ownership if racoon was built with support for admin
                 port.
                 adminsock path [owner group mode];
                         The path, owner, and group values specify the socket
                         path, owner, and group.  They must be quoted.  The
                         defaults are /var/racoon/racoon.sock, UID 0, and GID 0.
                         mode is the access mode in octal.  The default is 0600.
                 adminsock disabled;
                         This directive tells racoon to not listen on the admin
                         socket.
    
       Miscellaneous Global Parameters
         gss_id_enc enctype;
                 Older versions of racoon(8) used ISO-Latin-1 as the encoding of
                 the GSS-API identifier attribute.  For interoperability with
                 Microsoft Windows' GSS-API authentication scheme, the default
                 encoding has been changed to UTF-16LE.  The gss_id_enc parameter
                 allows racoon(8) to be configured to use the old encoding for
                 compatibility with existing racoon(8) installations.  The follow-
                 ing are valid values for enctype:
    
                 utf-16le
                         Use UTF-16LE to encode the GSS-API identifier attribute.
                         This is the default encoding.  This encoding is compati-
                         ble with Microsoft Windows.
                 latin1  Use ISO-Latin-1 to encode the GSS-API identifier
                         attribute.  This is the encoding used by older versions
                         of racoon(8).
    
         pfkey_buffer kBytes
                 Specifies the socket send/receive buffer size in kilobytes.
                 Numerous kernel PF_KEY implementations have problems with dumping
                 SAD/SDP with large amount of entries (this happens when 100s to
                 1000s of tunnels are configured).
    
                 The default value of 0 leaves everything at the OS-specific
                 default value.  If the default buffer size is greater than what
                 is specified here racoon will not decrease it.
    
                 When acting as responder, racoon picks the first proposal that
                 has one or more acceptable remote configurations.  When determin-
                 ing if a remote specification is matching the following informa-
                 tion is checked:
                 ?       The remote IP is checked against remote_address.
                 ?       ISAKMP exchange type is checked against exchange_mode.
                 ?       ISAKMP SA attributes must match a proposal block.
                 ?       The remote identity is matched against peers_identifier
                         if verify_identifier is on.
                 ?       If a certificate request was received, it must match the
                         issuer of certificate_type x509 certificate.  If certifi-
                         cate request without issuer name was sent, the
                         match_empty_cr parameter specifies whether or not remote
                         block matches.
    
                 Similarly, NAT-T is enabled if any of the initial remote configu-
                 ration candidates allow NAT-T.
    
                 Sections with inherit parent statements (where parent is either
                 address or a keyword anonymous) that have all values predefined
                 to those of a given parent.  In these sections it is enough to
                 redefine only the changed parameters.
    
                 The following are valid statements.
    
                 remote_address address;
                         Defines the IP address of the peer.
                 exchange_mode (main | aggressive | base);
                         Defines the exchange mode for phase 1 when racoon is the
                         initiator.  It also means the acceptable exchange mode
                         when racoon is the responder.  More than one mode can be
                         specified by separating them with a comma.  All of the
                         modes are acceptable.  The first exchange mode is what
                         racoon uses when it is the initiator.
                 doi ipsec_doi;
                         Means to use IPsec DOI as specified in RFC 2407.  You can
                         omit this statement.
                 situation identity_only;
                         Means to use SIT_IDENTITY_ONLY as specified in RFC 2407.
                         You can omit this statement.
                 my_identifier [qualifier] idtype ...;
                         Specifies the identifier sent to the remote host and the
                         type to use in the phase 1 negotiation.  address, fqdn,
                         user_fqdn, keyid, and asn1dn can be used as an idtype.
                         The qualifier is currently only used for keyid, and can
                         be either file or tag.  The possible values are :
                         my_identifier address [address];
                                 The type is the IP address.  This is the default
                                 type if you do not specify an identifier to use.
                         my_identifier user_fqdn string;
                                 The type is a USER_FQDN (user fully-qualified
                                 domain name).
    
                         built with this option.  The associated password is
                         looked up in the pre-shared key files, using the login
                         string as the key id.
                 peers_identifier idtype ...;
                         Specifies the peer's identifier to be received.  If it is
                         not defined then racoon(8) will not verify the peer's
                         identifier in ID payload transmitted from the peer.  If
                         it is defined, the behavior of the verification depends
                         on the flag of verify_identifier.  The usage of idtype is
                         the same as my_identifier except that the individual com-
                         ponent values of an asn1dn identifier may specified as *
                         to match any value (e.g. "C=XX, O=MyOrg, OU=*, CN=Mine").
                         The format of the specification should correspond to RFC
                         2253; in particular, commas and certain other characters
                         - ,=+<>#; - may be included in a name by preceding them
                         with a backslash "\", and arbitrary characters may be
                         inserted in a name with the "\nn" escape, where nn is the
                         hex representation of the ascii value of the desired
                         character.  Alternative acceptable peer identifiers may
                         be specified by repeating the peers_identifier statement.
                 verify_identifier (on | off);
                         If you want to verify the peer's identifier, set this to
                         on.  In this case, if the value defined by
                         peers_identifier is not the same as the peer's identifier
                         in the ID payload, the negotiation will fail.  The
                         default is off.
                 certificate_type certspec;
                         Specifies a certificate specification.  certspec is one
                         of followings:
                         x509 certfile privkeyfile;
                                 certfile means a file name of a certificate.
                                 privkeyfile means a file name of a secret key.
                         plain_rsa privkeyfile;
                                 privkeyfile means a file name of a private key
                                 generated by plainrsa-gen(8).  Required for RSA
                                 authentication.
                 ca_type cacertspec;
                         Specifies a root certificate authority specification.
                         cacertspec is one of followings:
                         x509 cacertfile;
                                 cacertfile means a file name of the root certifi-
                                 cate authority.  Default is /etc/openssl/cert.pem
                 mode_cfg (on | off);
                         Gather network information through ISAKMP mode configura-
                         tion.  Default is off.
                 weak_phase1_check (on | off);
                         Tells racoon to act on unencrypted deletion messages dur-
                         ing phase 1.  This is a small security risk, so the
                         default is off, meaning that racoon will keep on trying
                         to establish a connection even if the user credentials
                         are wrong, for instance.
                 peers_certfile (dnssec | certfile | plain_rsa pubkeyfile);
                         their environment:
                         LOCAL_ADDR
                                 The local address of the phase 1 SA.
                         LOCAL_PORT
                                 The local port used for IKE for the phase 1 SA.
                         REMOTE_ADDR

                         Specifies whether this remote block is a valid match when
                         a non-specific certificate request is received.  The

                 verify_cert (on | off);
                         By default, the identifier sent by the remote host (as
                         specified in its my_identifier statement) is compared
                         with the credentials in the certificate used to authenti-
                         cate the remote host as follows:
                         Type asn1dn:
                                 The entire certificate subject name is compared
                                 with the identifier, e.g. "C=XX, O=YY, ...".
                         Type address, fqdn, or user_fqdn:
                                 The certificate's subjectAltName is compared with
                                 the identifier.
                         If the two do not match the negotiation will fail.  If
                         you do not want to verify the identifier using the peer's
                         certificate, set this to off.
                 lifetime time number timeunit;
                         Define a lifetime of a certain time which will be pro-
                         posed in the phase 1 negotiations.  Any proposal will be
                         accepted, and the attribute(s) will not be proposed to
                         the peer if you do not specify it (them).  They can be
                         individually specified in each proposal.
                 ike_frag (on | off | force);
                         Enable receiver-side IKE fragmentation if racoon(8) has
                         been built with this feature.  If set to on, racoon will
                         advertise itself as being capable of receiving packets
                         split by IKE fragmentation.  This extension is there to
                         work around broken firewalls that do not work with frag-
                         mented UDP packets.  IKE fragmentation is always enabled
                         on the sender-side, and it is used if the peer advertises
                         itself as IKE fragmentation capable.  By selecting force,
                         IKE Fragmentation will be used when racoon is acting as
                         the initiator even before the remote peer has advertised
                         itself as IKE fragmentation capable.
                 esp_frag fraglen;
                         This option is only relevant if you use NAT traversal in
                         tunnel mode.  Its purpose is to work around broken DSL
                         routers that reject UDP fragments, by fragmenting the IP
                         packets before ESP encapsulation.  The result is ESP over
                         UDP of fragmented packets instead of fragmented ESP over
                         UDP packets (i.e., IP:UDP:ESP:frag(IP) instead of
                         frag(IP:UDP:ESP:IP)).  fraglen is the maximum size of the
                         fragments.  552 should work anywhere, but the higher
                         fraglen is, the better the performance.
    
                         Note that because PMTU discovery is broken on many sites,
                         you will have to use MSS clamping if you want TCP to work
                         correctly.

                                 by the responder, the responder will obey the
                                 proposal.  If PFS is required by both sides and
                                 the responder's group is not equal to the initia-
                                 tor's, then the responder will reject the pro-

                                 use the initiator's value.  If the responder's
                                 lifetime length is shorter than the initiator's,
                                 the responder uses its own length AND sends a
                                 RESPONDER-LIFETIME notify message to an initiator
                                 in the case of lifetime (phase 2 only).  For PFS,
                                 this directive behaves the same as strict.

                 generate_policy (on | off | require | unique);
                         This directive is for the responder.  Therefore you
                         should set passive to on in order that racoon(8) only
                         becomes a responder.  If the responder does not have any
                         policy in SPD during phase 2 negotiation, and the direc-
                         tive is set to on, then racoon(8) will choose the first
                         proposal in the SA payload from the initiator, and gener-
                         ate policy entries from the proposal.  It is useful to
                         negotiate with clients whose IP address is allocated
                         dynamically.  Note that an inappropriate policy might be
                         installed into the responder's SPD by the initiator, so
                         other communications might fail if such policies are
                         installed due to a policy mismatch between the initiator

                         reqid number (between 1 and IPSEC_MANUAL_REQID_MAX).
                         This directive is ignored in the initiator case.  The

                         build.  In that case you will get a warning when using

                 dpd_delay delay;
                         This option activates the DPD and sets the time (in sec-
                         onds) allowed between 2 proof of liveliness requests.
                         The default value is 0, which disables DPD monitoring,

                                 hostname(1) command.
    
         remote (address | anonymous) [[port]] [inherit parent] { statements }
                 Deprecated format of specifying a remote block.  This will be
                 removed in future.  It is a remnant from time when remote block
                 was decided solely based on the peers IP address.
    
                 This is equivalent to:
    
                 remote "address" [inherit "parent-address"] {
                         remote_address address;
                 }
    
       Sainfo Specifications
         sainfo (local_id | anonymous) (remote_id | clientaddr | anonymous) [from
                 idtype [string]] [group string] { statements }
                 Defines the parameters of the IKE phase 2 (IPsec-SA establish-
                 ment).
    
                 The local_id and remote_id strings are constructed like:
    
                 address address [/ prefix] [[port]] ul_proto
    
                 or
    
                 subnet address [/ prefix] [[port]] ul_proto
    
                 An id string should be expressed to match the exact value of an
                 ID payload.  This is not like a filter rule.  For example, if you
                 define 3ffe:501:4819::/48 as local_id.  3ffe:501:4819:1000:/64
                 will not match.  In the case of a longest prefix (selecting a
                 single host), address instructs to send ID type of ADDRESS while
                 subnet instructs to send ID type of SUBNET.  Otherwise, these
                 instructions are identical.
    
                 The anonymous keyword can be used to match any id.  The
                 clientaddr keyword can be used to match a remote id that is equal
                 to either the peer ip address or the mode_cfg ip address (if
                 assigned).  This can be useful to restrict policy generation when
                 racoon is acting as a client gateway for peers with dynamic ip
                 addresses.
                         can define 1, 2, 5, 14, 15, 16, 17, or 18 as the DH group
                         number.
                 lifetime time number timeunit;
                         define how long an IPsec-SA will be used, in timeunits.
                         Any proposal will be accepted, and no attribute(s) will
                         be proposed to the peer if you do not specify it(them).
                         See the proposal_check directive.
                 remoteid number;
                         Sainfos will only be used if their remoteid matches the
                         ph1id of the remote section used for phase 1.  Defaults
                         to 0, which is also the default for ph1id.
    
                 racoon(8) does not have a list of security protocols to be nego-
                 tiated.  The list of security protocols are passed by SPD in the
                 kernel.  Therefore you have to define all of the potential algo-
                 rithms in the phase 2 proposals even if there are algorithms
                 which will not be used.  These algorithms are define by using the
                 following three directives, with a single comma as the separator.
                 For algorithms that can take variable-length keys, algorithm
                 names can be followed by a key length, like "blowfish 448".
                 racoon(8) will compute the actual phase 2 proposals by computing
                 the permutation of the specified algorithms, and then combining
                 them with the security protocol specified by the SPD.  For exam-
                 ple, if des, 3des, hmac_md5, and hmac_sha1 are specified as algo-
                 rithms, we have four combinations for use with ESP, and two for
                 AH.  Then, based on the SPD settings, racoon(8) will construct
                 the actual proposals.  If the SPD entry asks for ESP only, there
                 will be 4 proposals.  If it asks for both AH and ESP, there will
                 be 8 proposals.  Note that the kernel may not support the algo-
                 rithm you have specified.

       Logging level
         log level;
                 Defines the logging level.  level is one of following: error,
                 warning, notify, info, debug or debug2.  The default is info.  If
                 you set the logging level too high on slower machines, IKE nego-
                 tiation can fail due to timing constraint changes.
    
       Specifies the way to pad
         padding { statements }
                 specifies the padding format.  The following are valid state-
                 ments:
    
       ISAKMP mode configuration settings
         mode_cfg { statements }
                 Defines the information to return for remote hosts' ISAKMP mode
                 config requests.  Also defines the authentication source for
                 remote peers authenticating through Xauth.
    
                 The following are valid statements:
                 auth_source (system | radius | pam | ldap);
                         Specifies the source for authentication of users through
                         Xauth.  system means to use the Unix user database.  This
                         is the default.  radius means to use a RADIUS server.  It
                         works only if racoon(8) was built with libradius support.
                         Radius configuration is handled by statements in the
                         radiuscfg section.  pam means to use PAM.  It works only
                         if racoon(8) was built with libpam support.  ldap means
                         to use LDAP.  It works only if racoon(8) was built with
                         libldap support.  LDAP configuration is handled by state-
                         ments in the ldapcfg section.
                 auth_groups group1, ...;
                         Specifies the group memberships for Xauth in quoted group
                         name strings.  When defined, the authenticating user must
                         be a member of at least one group for Xauth to succeed.
                 group_source (system | ldap);
                         Specifies the source for group validation of users
                         through Xauth.  system means to use the Unix user
                         database.  This is the default.  ldap means to use LDAP.
                         It works only if racoon(8) was built with libldap support
                         and requires LDAP authentication.  LDAP configuration is
                         handled by statements in the ldapcfg section.
                 conf_source (local | radius | ldap);
                         Specifies the source for IP addresses and netmask allo-
                         cated through ISAKMP mode config.  local means to use the
                         local IP pool defined by the network4 and pool_size
                         statements.  This is the default.  radius means to use a
                         RADIUS server.  It works only if racoon(8) was built with
                         libradius support and requires RADIUS authentication.
                         RADIUS configuration is handled by statements in the
                         radiuscfg section.  ldap means to use an LDAP server.  It
                         works only if racoon(8) was built with libldap support
                         and requires LDAP authentication.  LDAP configuration is
                         handled by statements in the ldapcfg section.
                 accounting (none | system | radius | pam);
                         Enables or disables accounting for Xauth logins and
                         logouts.  The default is none which disable accounting.
                         Specifying system enables system accounting through
                         utmp(5).  Specifying radius enables RADIUS accounting.
                         It works only if racoon(8) was built with libradius sup-
                         port and requires RADIUS authentication.  RADIUS configu-
                         ration is handled by statements in the radiuscfg section.
                         Specifying pam enables PAM accounting.  It works only if
                         racoon(8) was build with libpam support and requires PAM
    
                 dns4 addresses;
                         A list of IPv4 addresses for DNS servers, separated by
                         commas, or on multiple dns4 lines.
                 wins4 addresses;
                         A list of IPv4 address for WINS servers.  The keyword
                 nbns4   can also be used as an alias for
                 wins4.
                 split_network (include | local_lan) network/mask, ...
                         The network configuration to send, in CIDR notation (e.g.
                         192.168.1.0/24).  If include is specified, the tunnel
                         should be only used to encrypt the indicated destinations
                         ; otherwise, if local_lan is used, everything will pass
                         through the tunnel but those destinations.
                 default_domain domain;
                         The default DNS domain to send.
                 split_dns domain, ...
                         The split dns configuration to send, in quoted domain
                         name strings.  This list can be used to describe a list
                         of domain names for which a peer should query a modecfg
                         assigned dns server.  DNS queries for all other domains
                         would be handled locally.  (Cisco VPN client only).
                 banner path;
                         The path of a file displayed on the client at connection
                         time.  Default is /etc/motd.
                 auth_throttle delay;
                         On each failed Xauth authentication attempt, refuse new
                         attempts for a set delay of seconds.  This is to avoid
                         dictionary attacks on Xauth passwords.  Default is one
                         second.  Set to zero to disable authentication delay.
                 pfs_group group;
                         Sets the PFS group used in the client proposal (Cisco VPN
                         client only).  Default is 0.
                 save_passwd (on | off);
                         Allow the client to save the Xauth password (Cisco VPN
                         client only).  Default is off.
    
       Ldap configuration settings
         ldapcfg { statements }
                 Defines the parameters that will be used to communicate with an
                 ldap server for xauth authentication.
    
                 The following are valid statements:
                 version (2 | 3);
                         The ldap protocol version used to communicate with the
                         server.  The default is 3.
                 host (hostname | address);
                         The host name or ip address of the ldap server.  The
                         default is localhost.
                 port number;
                         The port that the ldap server is configured to listen on.
                         The default is 389.
                 base distinguished name;
                         The default value is cn.
                 attr_addr attribute name;
                 attr_mask attribute name;
                         The attributes used to specify a users network address
                         and subnet mask in an ldap directory.  These values are
                         forwarded during mode_cfg negotiation when the
                         conf_source is set to ldap.  The default values are
                         racoon-address and racoon-netmask.
                 attr_group attribute name;
                         The attribute used to specify a group name in an ldap
                         directory.  For example, if a group dn is
                         "cn=users,dc=my,dc=net" then the attribute would be "cn".
                         The default value is cn.
                 attr_member attribute name;
                         The attribute used to specify group membership in an ldap
                         directory.  The default value is member.
    
       Radius configuration settings
         radiuscfg { statements }
                 Defines the parameters that will be used to communicate with
                 radius servers for xauth authentication.  If radius is selected
                 as the xauth authentication or accounting source and no servers
                 are defined in this section, settings from the system
                 radius.conf(5) configuration file will be used instead.
    
                 The following are valid statements:
                 auth (hostname | address) [port] sharedsecret;
                         The host name or ip address, optional port value and
                         shared secret value of a radius authentication server.
                         Up to 5 radius authentication servers may be specified
                         using multiple lines.
                 acct (hostname | address) [port] sharedsecret;
                         The host name or ip address, optional port value and
                         shared secret value of a radius accounting server.  Up to
                         5 radius accounting servers may be specified using multi-
                         ple lines.
                 timeout seconds;
                         The timeout for receiving replies from radius servers.
                         The default is 3.
                 retries count;
                         The maximum number of repeated requests to make before
                         giving up on a radius server.  The default is 3.
    
       Special directives
         complex_bundle (on | off);
                 defines the interpretation of proposal in the case of SA bundle.
                 Normally "IP AH ESP IP payload" is proposed as "AH tunnel and ESP
                 tunnel".  The interpretation is more common to other IKE imple-
                 mentations, however, it allows very limited set of combinations
                 for proposals.  With the option enabled, it will be proposed as
                 "AH transport and ESP tunnel".  The default value is off.

         If you are configuring plain RSA authentication, the remote directive
         should look like the following:
