1 ##### Example wpa_supplicant configuration file ###############################
3 # This file describes configuration file format and lists all available option.
4 # Please also take a look at simpler configuration examples in 'examples'
7 # Empty lines and lines starting with # are ignored
9 # NOTE! This file may contain password information and should probably be made
10 # readable only by root user on multiuser systems.
12 # Note: All file paths in this configuration file should use full (absolute,
13 # not relative to working directory) path in order to allow working directory
14 # to be changed. This can happen if wpa_supplicant is run in the background.
16 # Whether to allow wpa_supplicant to update (overwrite) configuration
18 # This option can be used to allow wpa_supplicant to overwrite configuration
19 # file whenever configuration is changed (e.g., new network block is added with
20 # wpa_cli or wpa_gui, or a password is changed). This is required for
21 # wpa_cli/wpa_gui to be able to store the configuration changes permanently.
22 # Please note that overwriting configuration file will remove the comments from
26 # global configuration (shared by all network blocks)
28 # Parameters for the control interface. If this is specified, wpa_supplicant
29 # will open a control interface that is available for external programs to
30 # manage wpa_supplicant. The meaning of this string depends on which control
31 # interface mechanism is used. For all cases, the existence of this parameter
32 # in configuration is used to determine whether the control interface is
35 # For UNIX domain sockets (default on Linux and BSD): This is a directory that
36 # will be created for UNIX domain sockets for listening to requests from
37 # external programs (CLI/GUI, etc.) for status information and configuration.
38 # The socket file will be named based on the interface name, so multiple
39 # wpa_supplicant processes can be run at the same time if more than one
41 # /var/run/wpa_supplicant is the recommended directory for sockets and by
42 # default, wpa_cli will use it when trying to connect with wpa_supplicant.
44 # Access control for the control interface can be configured by setting the
45 # directory to allow only members of a group to use sockets. This way, it is
46 # possible to run wpa_supplicant as root (since it needs to change network
47 # configuration and open raw sockets) and still allow GUI/CLI components to be
48 # run as non-root users. However, since the control interface can be used to
49 # change the network configuration, this access needs to be protected in many
50 # cases. By default, wpa_supplicant is configured to use gid 0 (root). If you
51 # want to allow non-root users to use the control interface, add a new group
52 # and change this value to match with that group. Add users that should have
53 # control interface access to this group. If this variable is commented out or
54 # not included in the configuration file, group will not be changed from the
55 # value it got by default when the directory or socket was created.
57 # When configuring both the directory and group, use following format:
58 # DIR=/var/run/wpa_supplicant GROUP=wheel
59 # DIR=/var/run/wpa_supplicant GROUP=0
60 # (group can be either group name or gid)
62 # For UDP connections (default on Windows): The value will be ignored. This
63 # variable is just used to select that the control interface is to be created.
64 # The value can be set to, e.g., udp (ctrl_interface=udp)
66 # For Windows Named Pipe: This value can be used to set the security descriptor
67 # for controlling access to the control interface. Security descriptor can be
68 # set using Security Descriptor String Format (see http://msdn.microsoft.com/
69 # library/default.asp?url=/library/en-us/secauthz/security/
70 # security_descriptor_string_format.asp). The descriptor string needs to be
71 # prefixed with SDDL=. For example, ctrl_interface=SDDL=D: would set an empty
72 # DACL (which will reject all connections). See README-Windows.txt for more
73 # information about SDDL string format.
75 ctrl_interface=/var/run/wpa_supplicant
77 # IEEE 802.1X/EAPOL version
78 # wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which defines
79 # EAPOL version 2. However, there are many APs that do not handle the new
80 # version number correctly (they seem to drop the frames completely). In order
81 # to make wpa_supplicant interoperate with these APs, the version number is set
82 # to 1 by default. This configuration value can be used to set it to the new
86 # AP scanning/selection
87 # By default, wpa_supplicant requests driver to perform AP scanning and then
88 # uses the scan results to select a suitable AP. Another alternative is to
89 # allow the driver to take care of AP scanning and selection and use
90 # wpa_supplicant just to process EAPOL frames based on IEEE 802.11 association
91 # information from the driver.
92 # 1: wpa_supplicant initiates scanning and AP selection; if no APs matching to
93 # the currently enabled networks are found, a new network (IBSS or AP mode
94 # operation) may be initialized (if configured) (default)
95 # 0: driver takes care of scanning, AP selection, and IEEE 802.11 association
96 # parameters (e.g., WPA IE generation); this mode can also be used with
97 # non-WPA drivers when using IEEE 802.1X mode; do not try to associate with
98 # APs (i.e., external program needs to control association). This mode must
99 # also be used when using wired Ethernet drivers.
100 # 2: like 0, but associate with APs using security policy and SSID (but not
101 # BSSID); this can be used, e.g., with ndiswrapper and NDIS drivers to
102 # enable operation with hidden SSIDs and optimized roaming; in this mode,
103 # the network blocks in the configuration file are tried one by one until
104 # the driver reports successful association; each network block should have
105 # explicit security policy (i.e., only one option in the lists) for
106 # key_mgmt, pairwise, group, proto variables
107 # When using IBSS or AP mode, ap_scan=2 mode can force the new network to be
108 # created immediately regardless of scan results. ap_scan=1 mode will first try
109 # to scan for existing networks and only if no matches with the enabled
110 # networks are found, a new IBSS or AP mode network is created.
113 # EAP fast re-authentication
114 # By default, fast re-authentication is enabled for all EAP methods that
115 # support it. This variable can be used to disable fast re-authentication.
116 # Normally, there is no need to disable this.

241 # This is an optional set of parameters for automatic scanning
242 # within an interface in following format:
243 #autoscan=<autoscan module name>:<module parameters>
244 #Â autoscan is like bgscan but on disconnected or inactive state.
245 #Â For instance, on exponential module parameters would be <base>:<limit>
246 #autoscan=exponential:3:300
247 # Which means a delay between scans on a base exponential of 3,
248 #Â up to the limit of 300 seconds (3, 9, 27 ... 300)
249 #Â For periodic module, parameters would be <fixed interval>
250 #autoscan=periodic:30
251 #Â So a delay of 30 seconds will be applied between each scan
253 # filter_ssids - SSID-based scan result filtering
254 # 0 = do not filter scan results (default)
255 # 1 = only include configured SSIDs in scan results/BSS table
258 # Password (and passphrase, etc.) backend for external storage
259 # format: <backend name>[:<optional backend parameters>]
260 #ext_password_backend=test:pw1=password|pw2=testing

264 # This timeout value is used in P2P GO mode to clean up
266 #p2p_go_max_inactivity=300
268 # Opportunistic Key Caching (also known as Proactive Key Caching) default
269 # This parameter can be used to set the default behavior for the
270 # proactive_key_caching parameter. By default, OKC is disabled unless enabled
271 # with the global okc=1 parameter or with the per-network
272 # proactive_key_caching=1 parameter. With okc=1, OKC is enabled by default, but
273 # can be disabled with per-network proactive_key_caching=0 parameter.
276 # Protected Management Frames default
277 # This parameter can be used to set the default behavior for the ieee80211w
278 # parameter. By default, PMF is disabled unless enabled with the global pmf=1/2
279 # parameter or with the per-network ieee80211w=1/2 parameter. With pmf=1/2, PMF
280 # is enabled/required by default, but can be disabled with the per-network
281 # ieee80211w parameter.
284 # Interworking (IEEE 802.11u)
286 # Enable Interworking
289 # Homogenous ESS identifier

295 # Automatic network selection behavior
296 # 0 = do not automatically go through Interworking network selection
297 # (i.e., require explicit interworking_select command for this; default)
298 # 1 = perform Interworking network selection if one or more
299 # credentials have been configured and scan did not find a
300 # matching network block
305 # Each credential used for automatic network selection is configured as a set
306 # of parameters that are compared to the information advertised by the APs when
307 # interworking_select and interworking_connect commands are used.
311 # priority: Priority group
312 # By default, all networks and credentials get the same priority group
313 # (0). This field can be used to give higher priority for credentials
314 # (and similarly in struct wpa_ssid for network blocks) to change the
315 # Interworking automatic networking selection behavior. The matching
316 # network (based on either an enabled network block or a credential)
317 # with the highest priority value will be selected.
319 # pcsc: Use PC/SC and SIM/USIM card
321 # realm: Home Realm for Interworking
323 # username: Username for Interworking network selection
325 # password: Password for Interworking network selection
327 # ca_cert: CA certificate for Interworking network selection
329 # client_cert: File path to client certificate file (PEM/DER)
330 # This field is used with Interworking networking selection for a case
331 # where client certificate/private key is used for authentication
332 # (EAP-TLS). Full path to the file should be used since working
333 # directory may change when wpa_supplicant is run in the background.
335 # Alternatively, a named configuration blob can be used by setting
336 # this to blob://blob_name.
338 # private_key: File path to client private key file (PEM/DER/PFX)
339 # When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
340 # commented out. Both the private key and certificate will be read
341 # from the PKCS#12 file in this case. Full path to the file should be
342 # used since working directory may change when wpa_supplicant is run
345 # Windows certificate store can be used by leaving client_cert out and
346 # configuring private_key in one of the following formats:
348 # cert://substring_to_match
350 # hash://certificate_thumbprint_in_hex
352 # For example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
354 # Note that when running wpa_supplicant as an application, the user
355 # certificate store (My user account) is used, whereas computer store
356 # (Computer account) is used when running wpasvc as a service.
358 # Alternatively, a named configuration blob can be used by setting
359 # this to blob://blob_name.

369 # This is used to compare against the Domain Name List to figure out
370 # whether the AP is operated by the Home SP.
372 # roaming_consortium: Roaming Consortium OI
373 # If roaming_consortium_len is non-zero, this field contains the
374 # Roaming Consortium OI that can be used to determine which access
375 # points support authentication with this credential. This is an
376 # alternative to the use of the realm parameter. When using Roaming
377 # Consortium to match the network, the EAP parameters need to be
378 # pre-configured with the credential since the NAI Realm information
379 # may not be available or fetched.
381 # eap: Pre-configured EAP method
382 # This optional field can be used to specify which EAP method will be
383 # used with this credential. If not set, the EAP method is selected
384 # automatically based on ANQP information (e.g., NAI Realm).
386 # phase1: Pre-configure Phase 1 (outer authentication) parameters
387 # This optional field is used with like the 'eap' parameter.

441 # - a printf-escaped ASCII string P"<escaped string>"
444 # 0 = do not scan this SSID with specific Probe Request frames (default)
445 # 1 = scan with SSID-specific Probe Request frames (this can be used to

456 # priority groups will be iterated in decreasing priority (i.e., the larger the
457 # priority value, the sooner the network is matched against the scan results).
458 # Within each priority group, networks will be selected based on security
459 # policy, signal strength, etc.
460 # Please note that AP scanning with scan_ssid=1 and ap_scan=2 mode are not

586 # with EAP-PEAP or EAP-TTLS)
587 # MSCHAPV2 = EAP-MSCHAPv2 (cannot be used separately with WPA; to be used

599 # identity: Identity string for EAP
600 # This field is also used to configure user NAI for
601 # EAP-PSK/PAX/SAKE/GPSK.
602 # anonymous_identity: Anonymous identity string for EAP (to be used as the
603 # unencrypted identity with EAP types that support different tunnelled
604 # identity, e.g., EAP-TTLS). This field can also be used with
605 # EAP-SIM/AKA/AKA' to store the pseudonym identity.
606 # password: Password string for EAP. This field can include either the
607 # plaintext password (using ASCII or hex string) or a NtPasswordHash
608 # (16-byte MD4 hash of password) in hash:<32 hex digits> format.
609 # NtPasswordHash can only be used when the password is for MSCHAPv2 or
610 # MSCHAP (EAP-MSCHAPv2, EAP-TTLS/MSCHAPv2, EAP-TTLS/MSCHAP, LEAP).
611 # EAP-PSK (128-bit PSK), EAP-PAX (128-bit PSK), and EAP-SAKE (256-bit
612 # PSK) is also configured using this field. For EAP-GPSK, this is a
613 # variable length PSK. ext:<name of external password field> format can
614 # be used to indicate that the password is stored in external storage.
615 # ca_cert: File path to CA certificate file (PEM/DER). This file can have one
616 # or more trusted CA certificates. If ca_cert and ca_path are not
617 # included, server certificate will not be verified. This is insecure and
618 # a trusted CA certificate should always be configured when using
619 # EAP-TLS/TTLS/PEAP. Full path should be used since working directory may
620 # change when wpa_supplicant is run in the background.
622 # Alternatively, this can be used to only perform matching of the server
623 # certificate (SHA-256 hash of the DER encoded X.509 certificate). In
624 # this case, the possible CA certificates in the server certificate chain
625 # are ignored and only the server certificate is verified. This is
626 # configured with the following format:
627 # hash:://server/sha256/cert_hash_in_hex
628 # For example: "hash://server/sha256/
629 # 5a1bc1296205e6fdbe3979728efe3920798885c1c4590b5f90f43222d239ca6a"
631 # On Windows, trusted CA certificates can be loaded from the system
632 # certificate store by setting this to cert_store://<name>, e.g.,
633 # ca_cert="cert_store://CA" or ca_cert="cert_store://ROOT".
634 # Note that when running wpa_supplicant as an application, the user
635 # certificate store (My user account) is used, whereas computer store
636 # (Computer account) is used when running wpasvc as a service.
637 # ca_path: Directory path for CA certificate files (PEM). This path may
638 # contain multiple CA certificates in OpenSSL format. Common use for this
639 # is to point to system trusted CA list which is often installed into
640 # directory like /etc/ssl/certs. If configured, these certificates are
641 # added to the list of trusted CAs. ca_cert may also be included in that
642 # case, but it is not required.
643 # client_cert: File path to client certificate file (PEM/DER)
644 # Full path should be used since working directory may change when
645 # wpa_supplicant is run in the background.
646 # Alternatively, a named configuration blob can be used by setting this
647 # to blob://<blob name>.
648 # private_key: File path to client private key file (PEM/DER/PFX)
649 # When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
650 # commented out. Both the private key and certificate will be read from
651 # the PKCS#12 file in this case. Full path should be used since working
652 # directory may change when wpa_supplicant is run in the background.
653 # Windows certificate store can be used by leaving client_cert out and
654 # configuring private_key in one of the following formats:
655 # cert://substring_to_match
656 # hash://certificate_thumbprint_in_hex
657 # for example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
658 # Note that when running wpa_supplicant as an application, the user
659 # certificate store (My user account) is used, whereas computer store
660 # (Computer account) is used when running wpasvc as a service.
661 # Alternatively, a named configuration blob can be used by setting this
662 # to blob://<blob name>.
663 # private_key_passwd: Password for private key file (if left out, this will be
664 # asked through control interface)
665 # dh_file: File path to DH/DSA parameters file (in PEM format)
666 # This is an optional configuration file for setting parameters for an
667 # ephemeral DH key exchange. In most cases, the default RSA
668 # authentication does not use this configuration. However, it is possible
669 # setup RSA to use ephemeral DH key exchange. In addition, ciphers with
670 # DSA keys always use ephemeral DH keys. This can be used to achieve
671 # forward secrecy. If the file is in DSA parameters format, it will be
672 # automatically converted into DH params.
673 # subject_match: Substring to be matched against the subject of the
674 # authentication server certificate. If this string is set, the server
675 # sertificate is only accepted if it contains this string in the subject.
676 # The subject string is in following format:
677 # /C=US/ST=CA/L=San Francisco/CN=Test AS/emailAddress=as@example.com
678 # altsubject_match: Semicolon separated string of entries to be matched against
679 # the alternative subject name of the authentication server certificate.
680 # If this string is set, the server sertificate is only accepted if it
681 # contains one of the entries in an alternative subject name extension.
682 # altSubjectName string is in following format: TYPE:VALUE
683 # Example: EMAIL:server@example.com
684 # Example: DNS:server.example.com;DNS:server2.example.com
685 # Following types are supported: EMAIL, DNS, URI
686 # phase1: Phase1 (outer authentication, i.e., TLS tunnel) parameters
687 # (string with field-value pairs, e.g., "peapver=0" or
688 # "peapver=1 peaplabel=1")
689 # 'peapver' can be used to force which PEAP version (0 or 1) is used.
690 # 'peaplabel=1' can be used to force new label, "client PEAP encryption",
691 # to be used during key derivation when PEAPv1 or newer. Most existing
692 # PEAPv1 implementation seem to be using the old label, "client EAP
693 # encryption", and wpa_supplicant is now using that as the default value.
694 # Some servers, e.g., Radiator, may require peaplabel=1 configuration to
695 # interoperate with PEAPv1; see eap_testing.txt for more details.
696 # 'peap_outer_success=0' can be used to terminate PEAP authentication on
697 # tunneled EAP-Success. This is required with some RADIUS servers that
698 # implement draft-josefsson-pppext-eap-tls-eap-05.txt (e.g.,
699 # Lucent NavisRadius v4.4.0 with PEAP in "IETF Draft 5" mode)
700 # include_tls_length=1 can be used to force wpa_supplicant to include
701 # TLS Message Length field in all TLS messages even if they are not
703 # sim_min_num_chal=3 can be used to configure EAP-SIM to require three
704 # challenges (by default, it accepts 2 or 3)
705 # result_ind=1 can be used to enable EAP-SIM and EAP-AKA to use
706 # protected result indication.
707 # 'crypto_binding' option can be used to control PEAPv0 cryptobinding
709 # * 0 = do not use cryptobinding (default)
710 # * 1 = use cryptobinding if server supports it
711 # * 2 = require cryptobinding
712 # EAP-WSC (WPS) uses following options: pin=<Device Password> or
714 # phase2: Phase2 (inner authentication with TLS tunnel) parameters
715 # (string with field-value pairs, e.g., "auth=MSCHAPV2" for EAP-PEAP or
716 # "autheap=MSCHAPV2 autheap=MD5" for EAP-TTLS)
718 # TLS-based methods can use the following parameters to control TLS behavior
719 # (these are normally in the phase1 parameter, but can be used also in the
720 # phase2 parameter when EAP-TLS is used within the inner tunnel):
721 # tls_allow_md5=1 - allow MD5-based certificate signatures (depending on the
722 # TLS library, these may be disabled by default to enforce stronger
724 # tls_disable_time_checks=1 - ignore certificate validity time (this requests
725 # the TLS library to accept certificates even if they are not currently
726 # valid, i.e., have expired or have not yet become valid; this should be
727 # used only for testing purposes)
728 # tls_disable_session_ticket=1 - disable TLS Session Ticket extension
729 # tls_disable_session_ticket=0 - allow TLS Session Ticket extension to be used
730 # Note: If not set, this is automatically set to 1 for EAP-TLS/PEAP/TTLS
731 # as a workaround for broken authentication server implementations unless
732 # EAP workarounds are disabled with eap_workarounds=0.
733 # For EAP-FAST, this must be set to 0 (or left unconfigured for the
734 # default value to be used automatically).
736 # Following certificate/private key fields are used in inner Phase2
737 # authentication when using EAP-TTLS or EAP-PEAP.
738 # ca_cert2: File path to CA certificate file. This file can have one or more
739 # trusted CA certificates. If ca_cert2 and ca_path2 are not included,
740 # server certificate will not be verified. This is insecure and a trusted
741 # CA certificate should always be configured.
742 # ca_path2: Directory path for CA certificate files (PEM)
743 # client_cert2: File path to client certificate file
744 # private_key2: File path to client private key file
745 # private_key2_passwd: Password for private key file

747 # subject_match2: Substring to be matched against the subject of the
748 # authentication server certificate.
749 # altsubject_match2: Substring to be matched against the alternative subject
750 # name of the authentication server certificate.
752 # fragment_size: Maximum EAP fragment size in bytes (default 1398).
753 # This value limits the fragment size for EAP methods that support
754 # fragmentation (e.g., EAP-TLS and EAP-PEAP). This value should be set
755 # small enough to make the EAP messages fit in MTU of the network
756 # interface used for EAPOL. The default value is suitable for most
759 # EAP-FAST variables:
760 # pac_file: File path for the PAC entries. wpa_supplicant will need to be able
761 # to create this file and write updates to it when PAC is being
762 # provisioned or refreshed. Full path to the file should be used since
763 # working directory may change when wpa_supplicant is run in the
764 # background. Alternatively, a named configuration blob can be used by
765 # setting this to blob://<blob name>
766 # phase1: fast_provisioning option can be used to enable in-line provisioning
767 # of EAP-FAST credentials (PAC):
769 # 1 = allow unauthenticated provisioning,
770 # 2 = allow authenticated provisioning,
771 # 3 = allow both unauthenticated and authenticated provisioning
772 # fast_max_pac_list_len=<num> option can be used to set the maximum
773 # number of PAC entries to store in a PAC list (default: 10)
774 # fast_pac_format=binary option can be used to select binary format for
775 # storing PAC entries in order to save some space (the default
776 # text format uses about 2.5 times the size of minimal binary
779 # wpa_supplicant supports number of "EAP workarounds" to work around
780 # interoperability issues with incorrectly behaving authentication servers.
781 # These are enabled by default because some of the issues are present in large
782 # number of authentication servers. Strict EAP conformance mode can be
783 # configured by disabling workarounds with eap_workaround=0.
785 # Station inactivity limit
787 # If a station does not send anything in ap_max_inactivity seconds, an
788 # empty data frame is sent to it in order to verify whether it is
789 # still in range. If this frame is not ACKed, the station will be
790 # disassociated and then deauthenticated. This feature is used to
791 # clear station table of old entries when the STAs move out of the
794 # The station can associate again with the AP if it is still in range;
