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.

259 # priority: Priority group
260 # By default, all networks and credentials get the same priority group
261 # (0). This field can be used to give higher priority for credentials
262 # (and similarly in struct wpa_ssid for network blocks) to change the

278 # This field is used with Interworking networking selection for a case
279 # where client certificate/private key is used for authentication
280 # (EAP-TLS). Full path to the file should be used since working
281 # directory may change when wpa_supplicant is run in the background.
283 # Alternatively, a named configuration blob can be used by setting

286 # private_key: File path to client private key file (PEM/DER/PFX)
287 # When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
288 # commented out. Both the private key and certificate will be read
289 # from the PKCS#12 file in this case. Full path to the file should be
290 # used since working directory may change when wpa_supplicant is run

359 # 0 = do not scan this SSID with specific Probe Request frames (default)
360 # 1 = scan with SSID-specific Probe Request frames (this can be used to
361 # find APs that do not accept broadcast SSID or use multiple SSIDs;
362 # this will add latency to scanning, so enable this only when needed)
364 # bssid: BSSID (optional); if set, this network block is used only when
365 # associating with the AP using the configured BSSID
367 # priority: priority group (integer)
368 # By default, all networks will get same priority group (0). If some of the
369 # networks are more desirable, this field can be used to change the order in
370 # which wpa_supplicant goes through the networks when selecting a BSS. The
371 # priority groups will be iterated in decreasing priority (i.e., the larger the
372 # priority value, the sooner the network is matched against the scan results).
373 # Within each priority group, networks will be selected based on security
374 # policy, signal strength, etc.
375 # Please note that AP scanning with scan_ssid=1 and ap_scan=2 mode are not

535 # certificate (SHA-256 hash of the DER encoded X.509 certificate). In
536 # this case, the possible CA certificates in the server certificate chain
537 # are ignored and only the server certificate is verified. This is
538 # configured with the following format:
539 # hash:://server/sha256/cert_hash_in_hex
540 # For example: "hash://server/sha256/
541 # 5a1bc1296205e6fdbe3979728efe3920798885c1c4590b5f90f43222d239ca6a"
543 # On Windows, trusted CA certificates can be loaded from the system
544 # certificate store by setting this to cert_store://<name>, e.g.,
545 # ca_cert="cert_store://CA" or ca_cert="cert_store://ROOT".
546 # Note that when running wpa_supplicant as an application, the user
547 # certificate store (My user account) is used, whereas computer store
548 # (Computer account) is used when running wpasvc as a service.
549 # ca_path: Directory path for CA certificate files (PEM). This path may
550 # contain multiple CA certificates in OpenSSL format. Common use for this
551 # is to point to system trusted CA list which is often installed into
552 # directory like /etc/ssl/certs. If configured, these certificates are
553 # added to the list of trusted CAs. ca_cert may also be included in that
554 # case, but it is not required.
555 # client_cert: File path to client certificate file (PEM/DER)
556 # Full path should be used since working directory may change when
557 # wpa_supplicant is run in the background.
558 # Alternatively, a named configuration blob can be used by setting this
559 # to blob://<blob name>.
560 # private_key: File path to client private key file (PEM/DER/PFX)
561 # When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
562 # commented out. Both the private key and certificate will be read from
563 # the PKCS#12 file in this case. Full path should be used since working
564 # directory may change when wpa_supplicant is run in the background.
565 # Windows certificate store can be used by leaving client_cert out and
566 # configuring private_key in one of the following formats:
567 # cert://substring_to_match
568 # hash://certificate_thumbprint_in_hex
569 # for example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
570 # Note that when running wpa_supplicant as an application, the user
571 # certificate store (My user account) is used, whereas computer store
572 # (Computer account) is used when running wpasvc as a service.
573 # Alternatively, a named configuration blob can be used by setting this
574 # to blob://<blob name>.
575 # private_key_passwd: Password for private key file (if left out, this will be
576 # asked through control interface)
577 # dh_file: File path to DH/DSA parameters file (in PEM format)
578 # This is an optional configuration file for setting parameters for an
579 # ephemeral DH key exchange. In most cases, the default RSA
580 # authentication does not use this configuration. However, it is possible
581 # setup RSA to use ephemeral DH key exchange. In addition, ciphers with
582 # DSA keys always use ephemeral DH keys. This can be used to achieve
583 # forward secrecy. If the file is in DSA parameters format, it will be
584 # automatically converted into DH params.
585 # subject_match: Substring to be matched against the subject of the
586 # authentication server certificate. If this string is set, the server
587 # sertificate is only accepted if it contains this string in the subject.
588 # The subject string is in following format:
589 # /C=US/ST=CA/L=San Francisco/CN=Test AS/emailAddress=as@example.com
590 # altsubject_match: Semicolon separated string of entries to be matched against
591 # the alternative subject name of the authentication server certificate.
592 # If this string is set, the server sertificate is only accepted if it
593 # contains one of the entries in an alternative subject name extension.
594 # altSubjectName string is in following format: TYPE:VALUE
595 # Example: EMAIL:server@example.com
596 # Example: DNS:server.example.com;DNS:server2.example.com
597 # Following types are supported: EMAIL, DNS, URI
598 # phase1: Phase1 (outer authentication, i.e., TLS tunnel) parameters
599 # (string with field-value pairs, e.g., "peapver=0" or
600 # "peapver=1 peaplabel=1")
601 # 'peapver' can be used to force which PEAP version (0 or 1) is used.
602 # 'peaplabel=1' can be used to force new label, "client PEAP encryption",
603 # to be used during key derivation when PEAPv1 or newer. Most existing
604 # PEAPv1 implementation seem to be using the old label, "client EAP
605 # encryption", and wpa_supplicant is now using that as the default value.
606 # Some servers, e.g., Radiator, may require peaplabel=1 configuration to
607 # interoperate with PEAPv1; see eap_testing.txt for more details.
608 # 'peap_outer_success=0' can be used to terminate PEAP authentication on
609 # tunneled EAP-Success. This is required with some RADIUS servers that
610 # implement draft-josefsson-pppext-eap-tls-eap-05.txt (e.g.,
611 # Lucent NavisRadius v4.4.0 with PEAP in "IETF Draft 5" mode)
612 # include_tls_length=1 can be used to force wpa_supplicant to include
613 # TLS Message Length field in all TLS messages even if they are not
615 # sim_min_num_chal=3 can be used to configure EAP-SIM to require three
616 # challenges (by default, it accepts 2 or 3)
617 # result_ind=1 can be used to enable EAP-SIM and EAP-AKA to use
618 # protected result indication.
619 # 'crypto_binding' option can be used to control PEAPv0 cryptobinding
621 # * 0 = do not use cryptobinding (default)
622 # * 1 = use cryptobinding if server supports it
623 # * 2 = require cryptobinding
624 # EAP-WSC (WPS) uses following options: pin=<Device Password> or
626 # phase2: Phase2 (inner authentication with TLS tunnel) parameters
627 # (string with field-value pairs, e.g., "auth=MSCHAPV2" for EAP-PEAP or
628 # "autheap=MSCHAPV2 autheap=MD5" for EAP-TTLS)
629 # Following certificate/private key fields are used in inner Phase2
630 # authentication when using EAP-TTLS or EAP-PEAP.
631 # ca_cert2: File path to CA certificate file. This file can have one or more
632 # trusted CA certificates. If ca_cert2 and ca_path2 are not included,
633 # server certificate will not be verified. This is insecure and a trusted
634 # CA certificate should always be configured.
635 # ca_path2: Directory path for CA certificate files (PEM)
636 # client_cert2: File path to client certificate file
637 # private_key2: File path to client private key file
638 # private_key2_passwd: Password for private key file
639 # dh_file2: File path to DH/DSA parameters file (in PEM format)
640 # subject_match2: Substring to be matched against the subject of the
641 # authentication server certificate.
642 # altsubject_match2: Substring to be matched against the alternative subject
643 # name of the authentication server certificate.
645 # fragment_size: Maximum EAP fragment size in bytes (default 1398).
646 # This value limits the fragment size for EAP methods that support
647 # fragmentation (e.g., EAP-TLS and EAP-PEAP). This value should be set
648 # small enough to make the EAP messages fit in MTU of the network
649 # interface used for EAPOL. The default value is suitable for most
652 # EAP-FAST variables:
653 # pac_file: File path for the PAC entries. wpa_supplicant will need to be able
654 # to create this file and write updates to it when PAC is being
655 # provisioned or refreshed. Full path to the file should be used since
656 # working directory may change when wpa_supplicant is run in the
657 # background. Alternatively, a named configuration blob can be used by
658 # setting this to blob://<blob name>
659 # phase1: fast_provisioning option can be used to enable in-line provisioning
660 # of EAP-FAST credentials (PAC):
662 # 1 = allow unauthenticated provisioning,
663 # 2 = allow authenticated provisioning,
664 # 3 = allow both unauthenticated and authenticated provisioning
665 # fast_max_pac_list_len=<num> option can be used to set the maximum
666 # number of PAC entries to store in a PAC list (default: 10)
667 # fast_pac_format=binary option can be used to select binary format for
668 # storing PAC entries in order to save some space (the default
669 # text format uses about 2.5 times the size of minimal binary
672 # wpa_supplicant supports number of "EAP workarounds" to work around
673 # interoperability issues with incorrectly behaving authentication servers.
674 # These are enabled by default because some of the issues are present in large
675 # number of authentication servers. Strict EAP conformance mode can be
676 # configured by disabling workarounds with eap_workaround=0.
678 # Station inactivity limit
680 # If a station does not send anything in ap_max_inactivity seconds, an
681 # empty data frame is sent to it in order to verify whether it is
682 # still in range. If this frame is not ACKed, the station will be
683 # disassociated and then deauthenticated. This feature is used to
684 # clear station table of old entries when the STAs move out of the
687 # The station can associate again with the AP if it is still in range;
688 # this inactivity poll is just used as a nicer way of verifying
689 # inactivity; i.e., client will not report broken connection because
690 # disassociation frame is not sent immediately without first polling
691 # the STA with a data frame.
