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.
119 # OpenSSL Engine support
120 # These options can be used to load OpenSSL engines.
121 # The two engines that are supported currently are shown below:

269 # This field is used with Interworking networking selection for a case
270 # where client certificate/private key is used for authentication
271 # (EAP-TLS). Full path to the file should be used since working
272 # directory may change when wpa_supplicant is run in the background.
274 # Alternatively, a named configuration blob can be used by setting
275 # this to blob://blob_name.
277 # private_key: File path to client private key file (PEM/DER/PFX)
278 # When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
279 # commented out. Both the private key and certificate will be read
280 # from the PKCS#12 file in this case. Full path to the file should be
281 # used since working directory may change when wpa_supplicant is run

330 # (the first match is used).
332 # network block fields:
335 # 0 = this network can be used (default)
336 # 1 = this network block is disabled (can be enabled through ctrl_iface,
337 # e.g., with wpa_cli or wpa_gui)
339 # id_str: Network identifier string for external scripts. This value is passed
340 # to external action script through wpa_cli as WPA_ID_STR environment
341 # variable to make it easier to do network specific configuration.
343 # ssid: SSID (mandatory); either as an ASCII string with double quotation or
344 # as hex string; network name
347 # 0 = do not scan this SSID with specific Probe Request frames (default)
348 # 1 = scan with SSID-specific Probe Request frames (this can be used to
349 # find APs that do not accept broadcast SSID or use multiple SSIDs;
350 # this will add latency to scanning, so enable this only when needed)
352 # bssid: BSSID (optional); if set, this network block is used only when
353 # associating with the AP using the configured BSSID
355 # priority: priority group (integer)
356 # By default, all networks will get same priority group (0). If some of the
357 # networks are more desirable, this field can be used to change the order in
358 # which wpa_supplicant goes through the networks when selecting a BSS. The
359 # priority groups will be iterated in decreasing priority (i.e., the larger the
360 # priority value, the sooner the network is matched against the scan results).
361 # Within each priority group, networks will be selected based on security
362 # policy, signal strength, etc.
363 # Please note that AP scanning with scan_ssid=1 and ap_scan=2 mode are not
364 # using this priority to select the order for scanning. Instead, they try the

371 # Note: IBSS can only be used with key_mgmt NONE (plaintext and static WEP)
372 # and key_mgmt=WPA-NONE (fixed group key TKIP/CCMP). WPA-None requires
373 # following network block options:

527 # ca_path: Directory path for CA certificate files (PEM). This path may
528 # contain multiple CA certificates in OpenSSL format. Common use for this
529 # is to point to system trusted CA list which is often installed into
530 # directory like /etc/ssl/certs. If configured, these certificates are
531 # added to the list of trusted CAs. ca_cert may also be included in that
532 # case, but it is not required.
533 # client_cert: File path to client certificate file (PEM/DER)
534 # Full path should be used since working directory may change when
535 # wpa_supplicant is run in the background.
536 # Alternatively, a named configuration blob can be used by setting this
537 # to blob://<blob name>.
538 # private_key: File path to client private key file (PEM/DER/PFX)
539 # When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
540 # commented out. Both the private key and certificate will be read from
541 # the PKCS#12 file in this case. Full path should be used since working
542 # directory may change when wpa_supplicant is run in the background.
543 # Windows certificate store can be used by leaving client_cert out and
544 # configuring private_key in one of the following formats:
545 # cert://substring_to_match
546 # hash://certificate_thumbprint_in_hex
547 # for example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
548 # Note that when running wpa_supplicant as an application, the user
549 # certificate store (My user account) is used, whereas computer store
550 # (Computer account) is used when running wpasvc as a service.
551 # Alternatively, a named configuration blob can be used by setting this
552 # to blob://<blob name>.
553 # private_key_passwd: Password for private key file (if left out, this will be
554 # asked through control interface)
555 # dh_file: File path to DH/DSA parameters file (in PEM format)
556 # This is an optional configuration file for setting parameters for an
557 # ephemeral DH key exchange. In most cases, the default RSA
558 # authentication does not use this configuration. However, it is possible
559 # setup RSA to use ephemeral DH key exchange. In addition, ciphers with
560 # DSA keys always use ephemeral DH keys. This can be used to achieve
561 # forward secrecy. If the file is in DSA parameters format, it will be
562 # automatically converted into DH params.
563 # subject_match: Substring to be matched against the subject of the
564 # authentication server certificate. If this string is set, the server
565 # sertificate is only accepted if it contains this string in the subject.
566 # The subject string is in following format:
567 # /C=US/ST=CA/L=San Francisco/CN=Test AS/emailAddress=as@example.com
568 # altsubject_match: Semicolon separated string of entries to be matched against
569 # the alternative subject name of the authentication server certificate.
570 # If this string is set, the server sertificate is only accepted if it
571 # contains one of the entries in an alternative subject name extension.
572 # altSubjectName string is in following format: TYPE:VALUE
573 # Example: EMAIL:server@example.com
574 # Example: DNS:server.example.com;DNS:server2.example.com
575 # Following types are supported: EMAIL, DNS, URI
576 # phase1: Phase1 (outer authentication, i.e., TLS tunnel) parameters
577 # (string with field-value pairs, e.g., "peapver=0" or
578 # "peapver=1 peaplabel=1")
579 # 'peapver' can be used to force which PEAP version (0 or 1) is used.
580 # 'peaplabel=1' can be used to force new label, "client PEAP encryption",
581 # to be used during key derivation when PEAPv1 or newer. Most existing
582 # PEAPv1 implementation seem to be using the old label, "client EAP
583 # encryption", and wpa_supplicant is now using that as the default value.
584 # Some servers, e.g., Radiator, may require peaplabel=1 configuration to
585 # interoperate with PEAPv1; see eap_testing.txt for more details.
586 # 'peap_outer_success=0' can be used to terminate PEAP authentication on
587 # tunneled EAP-Success. This is required with some RADIUS servers that
588 # implement draft-josefsson-pppext-eap-tls-eap-05.txt (e.g.,
589 # Lucent NavisRadius v4.4.0 with PEAP in "IETF Draft 5" mode)
590 # include_tls_length=1 can be used to force wpa_supplicant to include
591 # TLS Message Length field in all TLS messages even if they are not
593 # sim_min_num_chal=3 can be used to configure EAP-SIM to require three
594 # challenges (by default, it accepts 2 or 3)
595 # result_ind=1 can be used to enable EAP-SIM and EAP-AKA to use
596 # protected result indication.
597 # 'crypto_binding' option can be used to control PEAPv0 cryptobinding
599 # * 0 = do not use cryptobinding (default)
600 # * 1 = use cryptobinding if server supports it
601 # * 2 = require cryptobinding
602 # EAP-WSC (WPS) uses following options: pin=<Device Password> or
604 # phase2: Phase2 (inner authentication with TLS tunnel) parameters
605 # (string with field-value pairs, e.g., "auth=MSCHAPV2" for EAP-PEAP or
606 # "autheap=MSCHAPV2 autheap=MD5" for EAP-TTLS)
607 # Following certificate/private key fields are used in inner Phase2
608 # authentication when using EAP-TTLS or EAP-PEAP.
609 # ca_cert2: File path to CA certificate file. This file can have one or more
610 # trusted CA certificates. If ca_cert2 and ca_path2 are not included,
611 # server certificate will not be verified. This is insecure and a trusted
612 # CA certificate should always be configured.
613 # ca_path2: Directory path for CA certificate files (PEM)
614 # client_cert2: File path to client certificate file
615 # private_key2: File path to client private key file
616 # private_key2_passwd: Password for private key file
617 # dh_file2: File path to DH/DSA parameters file (in PEM format)
618 # subject_match2: Substring to be matched against the subject of the
619 # authentication server certificate.
620 # altsubject_match2: Substring to be matched against the alternative subject
621 # name of the authentication server certificate.
623 # fragment_size: Maximum EAP fragment size in bytes (default 1398).
624 # This value limits the fragment size for EAP methods that support
625 # fragmentation (e.g., EAP-TLS and EAP-PEAP). This value should be set
626 # small enough to make the EAP messages fit in MTU of the network
627 # interface used for EAPOL. The default value is suitable for most
630 # EAP-FAST variables:
631 # pac_file: File path for the PAC entries. wpa_supplicant will need to be able
632 # to create this file and write updates to it when PAC is being
633 # provisioned or refreshed. Full path to the file should be used since
634 # working directory may change when wpa_supplicant is run in the
635 # background. Alternatively, a named configuration blob can be used by
636 # setting this to blob://<blob name>
637 # phase1: fast_provisioning option can be used to enable in-line provisioning
638 # of EAP-FAST credentials (PAC):
640 # 1 = allow unauthenticated provisioning,
641 # 2 = allow authenticated provisioning,
642 # 3 = allow both unauthenticated and authenticated provisioning
643 # fast_max_pac_list_len=<num> option can be used to set the maximum
644 # number of PAC entries to store in a PAC list (default: 10)
645 # fast_pac_format=binary option can be used to select binary format for
646 # storing PAC entries in order to save some space (the default
647 # text format uses about 2.5 times the size of minimal binary
650 # wpa_supplicant supports number of "EAP workarounds" to work around
651 # interoperability issues with incorrectly behaving authentication servers.
652 # These are enabled by default because some of the issues are present in large
653 # number of authentication servers. Strict EAP conformance mode can be
654 # configured by disabling workarounds with eap_workaround=0.
