      1 ##### Example wpa_supplicant configuration file ###############################
      2 #
      3 # This file describes configuration file format and lists all available option.
      4 # Please also take a look at simpler configuration examples in 'examples'
      5 # subdirectory.
      6 #
      7 # Empty lines and lines starting with # are ignored
      8 
      9 # NOTE! This file may contain password information and should probably be made
     10 # readable only by root user on multiuser systems.
     11 
     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.
     15 
     16 # Whether to allow wpa_supplicant to update (overwrite) configuration
     17 #
     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
     23 # it.
     24 #update_config=1
     25 
     26 # global configuration (shared by all network blocks)
     27 #
     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
     33 # enabled.
     34 #
     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
     40 # interface is used.
     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.
     43 #
     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.
     56 #
     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)
     61 #
     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)
     65 #
     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.
     74 #
     75 ctrl_interface=/var/run/wpa_supplicant
     76 
     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
     83 # version (2).
     84 # Note: When using MACsec, eapol_version shall be set to 3, which is
     85 # defined in IEEE Std 802.1X-2010.
     86 eapol_version=1
     87 
     88 # AP scanning/selection
     89 # By default, wpa_supplicant requests driver to perform AP scanning and then
     90 # uses the scan results to select a suitable AP. Another alternative is to
     91 # allow the driver to take care of AP scanning and selection and use
     92 # wpa_supplicant just to process EAPOL frames based on IEEE 802.11 association
     93 # information from the driver.
     94 # 1: wpa_supplicant initiates scanning and AP selection; if no APs matching to
     95 #    the currently enabled networks are found, a new network (IBSS or AP mode
     96 #    operation) may be initialized (if configured) (default)
     97 # 0: driver takes care of scanning, AP selection, and IEEE 802.11 association
     98 #    parameters (e.g., WPA IE generation); this mode can also be used with
     99 #    non-WPA drivers when using IEEE 802.1X mode; do not try to associate with
    100 #    APs (i.e., external program needs to control association). This mode must
    101 #    also be used when using wired Ethernet drivers.
    102 #    Note: macsec_qca driver is one type of Ethernet driver which implements
    103 #    macsec feature.
    104 # 2: like 0, but associate with APs using security policy and SSID (but not
    105 #    BSSID); this can be used, e.g., with ndiswrapper and NDIS drivers to
    106 #    enable operation with hidden SSIDs and optimized roaming; in this mode,
    107 #    the network blocks in the configuration file are tried one by one until
    108 #    the driver reports successful association; each network block should have
    109 #    explicit security policy (i.e., only one option in the lists) for
    110 #    key_mgmt, pairwise, group, proto variables
    111 # When using IBSS or AP mode, ap_scan=2 mode can force the new network to be
    112 # created immediately regardless of scan results. ap_scan=1 mode will first try
    113 # to scan for existing networks and only if no matches with the enabled
    114 # networks are found, a new IBSS or AP mode network is created.
    115 ap_scan=1
    116 
    117 # MPM residency
    118 # By default, wpa_supplicant implements the mesh peering manager (MPM) for an
    119 # open mesh. However, if the driver can implement the MPM, you may set this to
    120 # 0 to use the driver version. When AMPE is enabled, the wpa_supplicant MPM is
    121 # always used.
    122 # 0: MPM lives in the driver

    617 #
    618 # priority: priority group (integer)
    619 # By default, all networks will get same priority group (0). If some of the
    620 # networks are more desirable, this field can be used to change the order in

    818 #	included, server certificate will not be verified. This is insecure and
    819 #	a trusted CA certificate should always be configured when using
    820 #	EAP-TLS/TTLS/PEAP. Full path should be used since working directory may
    821 #	change when wpa_supplicant is run in the background.
    822 #
    823 #	Alternatively, this can be used to only perform matching of the server
    824 #	certificate (SHA-256 hash of the DER encoded X.509 certificate). In
    825 #	this case, the possible CA certificates in the server certificate chain
    826 #	are ignored and only the server certificate is verified. This is
    827 #	configured with the following format:
    828 #	hash:://server/sha256/cert_hash_in_hex
    829 #	For example: "hash://server/sha256/
    830 #	5a1bc1296205e6fdbe3979728efe3920798885c1c4590b5f90f43222d239ca6a"
    831 #
    832 #	On Windows, trusted CA certificates can be loaded from the system
    833 #	certificate store by setting this to cert_store://<name>, e.g.,
    834 #	ca_cert="cert_store://CA" or ca_cert="cert_store://ROOT".
    835 #	Note that when running wpa_supplicant as an application, the user
    836 #	certificate store (My user account) is used, whereas computer store
    837 #	(Computer account) is used when running wpasvc as a service.
    838 # ca_path: Directory path for CA certificate files (PEM). This path may
    839 #	contain multiple CA certificates in OpenSSL format. Common use for this
    840 #	is to point to system trusted CA list which is often installed into
    841 #	directory like /etc/ssl/certs. If configured, these certificates are
    842 #	added to the list of trusted CAs. ca_cert may also be included in that
    843 #	case, but it is not required.
    844 # client_cert: File path to client certificate file (PEM/DER)
    845 #	Full path should be used since working directory may change when
    846 #	wpa_supplicant is run in the background.
    847 #	Alternatively, a named configuration blob can be used by setting this
    848 #	to blob://<blob name>.
    849 # private_key: File path to client private key file (PEM/DER/PFX)
    850 #	When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
    851 #	commented out. Both the private key and certificate will be read from
    852 #	the PKCS#12 file in this case. Full path should be used since working
    853 #	directory may change when wpa_supplicant is run in the background.
    854 #	Windows certificate store can be used by leaving client_cert out and
    855 #	configuring private_key in one of the following formats:
    856 #	cert://substring_to_match
    857 #	hash://certificate_thumbprint_in_hex
    858 #	for example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
    859 #	Note that when running wpa_supplicant as an application, the user
    860 #	certificate store (My user account) is used, whereas computer store
    861 #	(Computer account) is used when running wpasvc as a service.
    862 #	Alternatively, a named configuration blob can be used by setting this
    863 #	to blob://<blob name>.
    864 # private_key_passwd: Password for private key file (if left out, this will be
    865 #	asked through control interface)
    866 # dh_file: File path to DH/DSA parameters file (in PEM format)
    867 #	This is an optional configuration file for setting parameters for an
    868 #	ephemeral DH key exchange. In most cases, the default RSA
    869 #	authentication does not use this configuration. However, it is possible
    870 #	setup RSA to use ephemeral DH key exchange. In addition, ciphers with
    871 #	DSA keys always use ephemeral DH keys. This can be used to achieve
    872 #	forward secrecy. If the file is in DSA parameters format, it will be
    873 #	automatically converted into DH params.
    874 # subject_match: Substring to be matched against the subject of the
    875 #	authentication server certificate. If this string is set, the server
    876 #	sertificate is only accepted if it contains this string in the subject.
    877 #	The subject string is in following format:
    878 #	/C=US/ST=CA/L=San Francisco/CN=Test AS/emailAddress=as (at] example.com
    879 #	Note: Since this is a substring match, this cannot be used securily to
    880 #	do a suffix match against a possible domain name in the CN entry. For
    881 #	such a use case, domain_suffix_match or domain_match should be used
    882 #	instead.
    883 # altsubject_match: Semicolon separated string of entries to be matched against
    884 #	the alternative subject name of the authentication server certificate.
    885 #	If this string is set, the server sertificate is only accepted if it
    886 #	contains one of the entries in an alternative subject name extension.
    887 #	altSubjectName string is in following format: TYPE:VALUE
    888 #	Example: EMAIL:server (at] example.com
    889 #	Example: DNS:server.example.com;DNS:server2.example.com
    890 #	Following types are supported: EMAIL, DNS, URI
    891 # domain_suffix_match: Constraint for server domain name. If set, this FQDN is
    892 #	used as a suffix match requirement for the AAAserver certificate in
    893 #	SubjectAltName dNSName element(s). If a matching dNSName is found, this
    894 #	constraint is met. If no dNSName values are present, this constraint is
    895 #	matched against SubjectName CN using same suffix match comparison.
    896 #
    897 #	Suffix match here means that the host/domain name is compared one label
    898 #	at a time starting from the top-level domain and all the labels in
    899 #	domain_suffix_match shall be included in the certificate. The
    900 #	certificate may include additional sub-level labels in addition to the
    901 #	required labels.
    902 #
    903 #	For example, domain_suffix_match=example.com would match
    904 #	test.example.com but would not match test-example.com.
    905 # domain_match: Constraint for server domain name
    906 #	If set, this FQDN is used as a full match requirement for the
    907 #	server certificate in SubjectAltName dNSName element(s). If a
    908 #	matching dNSName is found, this constraint is met. If no dNSName
    909 #	values are present, this constraint is matched against SubjectName CN
    910 #	using same full match comparison. This behavior is similar to
    911 #	domain_suffix_match, but has the requirement of a full match, i.e.,
    912 #	no subdomains or wildcard matches are allowed. Case-insensitive
    913 #	comparison is used, so "Example.com" matches "example.com", but would
    914 #	not match "test.Example.com".
    915 # phase1: Phase1 (outer authentication, i.e., TLS tunnel) parameters
    916 #	(string with field-value pairs, e.g., "peapver=0" or
    917 #	"peapver=1 peaplabel=1")
    918 #	'peapver' can be used to force which PEAP version (0 or 1) is used.
    919 #	'peaplabel=1' can be used to force new label, "client PEAP encryption",
    920 #	to be used during key derivation when PEAPv1 or newer. Most existing
    921 #	PEAPv1 implementation seem to be using the old label, "client EAP
    922 #	encryption", and wpa_supplicant is now using that as the default value.
    923 #	Some servers, e.g., Radiator, may require peaplabel=1 configuration to
    924 #	interoperate with PEAPv1; see eap_testing.txt for more details.
    925 #	'peap_outer_success=0' can be used to terminate PEAP authentication on
    926 #	tunneled EAP-Success. This is required with some RADIUS servers that
    927 #	implement draft-josefsson-pppext-eap-tls-eap-05.txt (e.g.,
    928 #	Lucent NavisRadius v4.4.0 with PEAP in "IETF Draft 5" mode)
    929 #	include_tls_length=1 can be used to force wpa_supplicant to include
    930 #	TLS Message Length field in all TLS messages even if they are not
    931 #	fragmented.
    932 #	sim_min_num_chal=3 can be used to configure EAP-SIM to require three
    933 #	challenges (by default, it accepts 2 or 3)
    934 #	result_ind=1 can be used to enable EAP-SIM and EAP-AKA to use
    935 #	protected result indication.
    936 #	'crypto_binding' option can be used to control PEAPv0 cryptobinding
    937 #	behavior:
    938 #	 * 0 = do not use cryptobinding (default)
    939 #	 * 1 = use cryptobinding if server supports it
    940 #	 * 2 = require cryptobinding
    941 #	EAP-WSC (WPS) uses following options: pin=<Device Password> or
    942 #	pbc=1.
    943 #
    944 #	For wired IEEE 802.1X authentication, "allow_canned_success=1" can be
    945 #	used to configure a mode that allows EAP-Success (and EAP-Failure)
    946 #	without going through authentication step. Some switches use such
    947 #	sequence when forcing the port to be authorized/unauthorized or as a
    948 #	fallback option if the authentication server is unreachable. By default,
    949 #	wpa_supplicant discards such frames to protect against potential attacks
    950 #	by rogue devices, but this option can be used to disable that protection
    951 #	for cases where the server/authenticator does not need to be
    952 #	authenticated.
    953 # phase2: Phase2 (inner authentication with TLS tunnel) parameters
    954 #	(string with field-value pairs, e.g., "auth=MSCHAPV2" for EAP-PEAP or
    955 #	"autheap=MSCHAPV2 autheap=MD5" for EAP-TTLS). "mschapv2_retry=0" can be
    956 #	used to disable MSCHAPv2 password retry in authentication failure cases.
    957 #
    958 # TLS-based methods can use the following parameters to control TLS behavior
    959 # (these are normally in the phase1 parameter, but can be used also in the
    960 # phase2 parameter when EAP-TLS is used within the inner tunnel):
    961 # tls_allow_md5=1 - allow MD5-based certificate signatures (depending on the
    962 #	TLS library, these may be disabled by default to enforce stronger
    963 #	security)
    964 # tls_disable_time_checks=1 - ignore certificate validity time (this requests
    965 #	the TLS library to accept certificates even if they are not currently
    966 #	valid, i.e., have expired or have not yet become valid; this should be
    967 #	used only for testing purposes)
    968 # tls_disable_session_ticket=1 - disable TLS Session Ticket extension
    969 # tls_disable_session_ticket=0 - allow TLS Session Ticket extension to be used
