##### Example wpa_supplicant configuration file ############################### # # This file describes configuration file format and lists all available option. # Please also take a look at simpler configuration examples in 'examples' # subdirectory. # # Empty lines and lines starting with # are ignored # NOTE! This file may contain password information and should probably be made # readable only by root user on multiuser systems. # Note: All file paths in this configuration file should use full (absolute, # not relative to working directory) path in order to allow working directory # to be changed. This can happen if wpa_supplicant is run in the background. # Whether to allow wpa_supplicant to update (overwrite) configuration # # This option can be used to allow wpa_supplicant to overwrite configuration # file whenever configuration is changed (e.g., new network block is added with # wpa_cli or wpa_gui, or a password is changed). This is required for # wpa_cli/wpa_gui to be able to store the configuration changes permanently. # Please note that overwriting configuration file will remove the comments from # it. #update_config=1 # global configuration (shared by all network blocks) # # Parameters for the control interface. If this is specified, wpa_supplicant # will open a control interface that is available for external programs to # manage wpa_supplicant. The meaning of this string depends on which control # interface mechanism is used. For all cases, the existence of this parameter # in configuration is used to determine whether the control interface is # enabled. # # For UNIX domain sockets (default on Linux and BSD): This is a directory that # will be created for UNIX domain sockets for listening to requests from # external programs (CLI/GUI, etc.) for status information and configuration. # The socket file will be named based on the interface name, so multiple # wpa_supplicant processes can be run at the same time if more than one # interface is used. # /var/run/wpa_supplicant is the recommended directory for sockets and by # default, wpa_cli will use it when trying to connect with wpa_supplicant. # # Access control for the control interface can be configured by setting the # directory to allow only members of a group to use sockets. This way, it is # possible to run wpa_supplicant as root (since it needs to change network # configuration and open raw sockets) and still allow GUI/CLI components to be # run as non-root users. However, since the control interface can be used to # change the network configuration, this access needs to be protected in many # cases. By default, wpa_supplicant is configured to use gid 0 (root). If you # want to allow non-root users to use the control interface, add a new group # and change this value to match with that group. Add users that should have # control interface access to this group. If this variable is commented out or # not included in the configuration file, group will not be changed from the # value it got by default when the directory or socket was created. # # When configuring both the directory and group, use following format: # DIR=/var/run/wpa_supplicant GROUP=wheel # DIR=/var/run/wpa_supplicant GROUP=0 # (group can be either group name or gid) # # For UDP connections (default on Windows): The value will be ignored. This # variable is just used to select that the control interface is to be created. # The value can be set to, e.g., udp (ctrl_interface=udp) # # For Windows Named Pipe: This value can be used to set the security descriptor # for controlling access to the control interface. Security descriptor can be # set using Security Descriptor String Format (see http://msdn.microsoft.com/ # library/default.asp?url=/library/en-us/secauthz/security/ # security_descriptor_string_format.asp). The descriptor string needs to be # prefixed with SDDL=. For example, ctrl_interface=SDDL=D: would set an empty # DACL (which will reject all connections). See README-Windows.txt for more # information about SDDL string format. # ctrl_interface=/var/run/wpa_supplicant # IEEE 802.1X/EAPOL version # wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which defines # EAPOL version 2. However, there are many APs that do not handle the new # version number correctly (they seem to drop the frames completely). In order # to make wpa_supplicant interoperate with these APs, the version number is set # to 1 by default. This configuration value can be used to set it to the new # version (2). # Note: When using MACsec, eapol_version shall be set to 3, which is # defined in IEEE Std 802.1X-2010. eapol_version=1 # AP scanning/selection # By default, wpa_supplicant requests driver to perform AP scanning and then # uses the scan results to select a suitable AP. Another alternative is to # allow the driver to take care of AP scanning and selection and use # wpa_supplicant just to process EAPOL frames based on IEEE 802.11 association # information from the driver. # 1: wpa_supplicant initiates scanning and AP selection; if no APs matching to # the currently enabled networks are found, a new network (IBSS or AP mode # operation) may be initialized (if configured) (default) # 0: driver takes care of scanning, AP selection, and IEEE 802.11 association # parameters (e.g., WPA IE generation); this mode can also be used with # non-WPA drivers when using IEEE 802.1X mode; do not try to associate with # APs (i.e., external program needs to control association). This mode must # also be used when using wired Ethernet drivers. # Note: macsec_qca driver is one type of Ethernet driver which implements # macsec feature. # 2: like 0, but associate with APs using security policy and SSID (but not # BSSID); this can be used, e.g., with ndiswrapper and NDIS drivers to # enable operation with hidden SSIDs and optimized roaming; in this mode, # the network blocks in the configuration file are tried one by one until # the driver reports successful association; each network block should have # explicit security policy (i.e., only one option in the lists) for # key_mgmt, pairwise, group, proto variables # When using IBSS or AP mode, ap_scan=2 mode can force the new network to be # created immediately regardless of scan results. ap_scan=1 mode will first try # to scan for existing networks and only if no matches with the enabled # networks are found, a new IBSS or AP mode network is created. ap_scan=1 # EAP fast re-authentication # By default, fast re-authentication is enabled for all EAP methods that # support it.

This field can include either the # plaintext password (using ASCII or hex string) or a NtPasswordHash # (16-byte MD4 hash of password) in hash:<32 hex digits> format. # NtPasswordHash can only be used when the password is for MSCHAPv2 or # MSCHAP (EAP-MSCHAPv2, EAP-TTLS/MSCHAPv2, EAP-TTLS/MSCHAP, LEAP). # EAP-PSK (128-bit PSK), EAP-PAX (128-bit PSK), and EAP-SAKE (256-bit # PSK) is also configured using this field. For EAP-GPSK, this is a # variable length PSK. ext: format can # be used to indicate that the password is stored in external storage. # ca_cert: File path to CA certificate file (PEM/DER). This file can have one # or more trusted CA certificates. If ca_cert and ca_path are not # included, server certificate will not be verified. This is insecure and # a trusted CA certificate should always be configured when using # EAP-TLS/TTLS/PEAP. Full path should be used since working directory may # change when wpa_supplicant is run in the background. # # Alternatively, this can be used to only perform matching of the server # certificate (SHA-256 hash of the DER encoded X.509 certificate). In # this case, the possible CA certificates in the server certificate chain # are ignored and only the server certificate is verified. This is # configured with the following format: # hash:://server/sha256/cert_hash_in_hex # For example: "hash://server/sha256/ # 5a1bc1296205e6fdbe3979728efe3920798885c1c4590b5f90f43222d239ca6a" # # On Windows, trusted CA certificates can be loaded from the system # certificate store by setting this to cert_store://, e.g., # ca_cert="cert_store://CA" or ca_cert="cert_store://ROOT". # Note that when running wpa_supplicant as an application, the user # certificate store (My user account) is used, whereas computer store # (Computer account) is used when running wpasvc as a service. # ca_path: Directory path for CA certificate files (PEM). This path may # contain multiple CA certificates in OpenSSL format. Common use for this # is to point to system trusted CA list which is often installed into # directory like /etc/ssl/certs. If configured, these certificates are # added to the list of trusted CAs. ca_cert may also be included in that # case, but it is not required. # client_cert: File path to client certificate file (PEM/DER) # Full path should be used since working directory may change when # wpa_supplicant is run in the background. # Alternatively, a named configuration blob can be used by setting this # to blob://. # private_key: File path to client private key file (PEM/DER/PFX) # When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be # commented out. Both the private key and certificate will be read from # the PKCS#12 file in this case. Full path should be used since working # directory may change when wpa_supplicant is run in the background. # Windows certificate store can be used by leaving client_cert out and # configuring private_key in one of the following formats: # cert://substring_to_match # hash://certificate_thumbprint_in_hex # for example: private_key="hash://63093aa9c47f56ae88334c7b65a4" # Note that when running wpa_supplicant as an application, the user # certificate store (My user account) is used, whereas computer store # (Computer account) is used when running wpasvc as a service. # Alternatively, a named configuration blob can be used by setting this # to blob://. # private_key_passwd: Password for private key file (if left out, this will be # asked through control interface) # dh_file: File path to DH/DSA parameters file (in PEM format) # This is an optional configuration file for setting parameters for an # ephemeral DH key exchange. In most cases, the default RSA # authentication does not use this configuration. However, it is possible # setup RSA to use ephemeral DH key exchange. In addition, ciphers with # DSA keys always use ephemeral DH keys. This can be used to achieve # forward secrecy. If the file is in DSA parameters format, it will be # automatically converted into DH params. # subject_match: Substring to be matched against the subject of the # authentication server certificate. If this string is set, the server # sertificate is only accepted if it contains this string in the subject. # The subject string is in following format: # /C=US/ST=CA/L=San Francisco/CN=Test AS/emailAddress=as@example.com # altsubject_match: Semicolon separated string of entries to be matched against # the alternative subject name of the authentication server certificate. # If this string is set, the server sertificate is only accepted if it # contains one of the entries in an alternative subject name extension. # altSubjectName string is in following format: TYPE:VALUE # Example: EMAIL:server@example.com # Example: DNS:server.example.com;DNS:server2.example.com # Following types are supported: EMAIL, DNS, URI # phase1: Phase1 (outer authentication, i.e., TLS tunnel) parameters # (string with field-value pairs, e.g., "peapver=0" or # "peapver=1 peaplabel=1") # 'peapver' can be used to force which PEAP version (0 or 1) is used. # 'peaplabel=1' can be used to force new label, "client PEAP encryption", # to be used during key derivation when PEAPv1 or newer. Most existing # PEAPv1 implementation seem to be using the old label, "client EAP # encryption", and wpa_supplicant is now using that as the default value. # Some servers, e.g., Radiator, may require peaplabel=1 configuration to # interoperate with PEAPv1; see eap_testing.txt for more details. # 'peap_outer_success=0' can be used to terminate PEAP authentication on # tunneled EAP-Success. This is required with some RADIUS servers that # implement draft-josefsson-pppext-eap-tls-eap-05.txt (e.g., # Lucent NavisRadius v4.4.0 with PEAP in "IETF Draft 5" mode) # include_tls_length=1 can be used to force wpa_supplicant to include # TLS Message Length field in all TLS messages even if they are not # fragmented. # sim_min_num_chal=3 can be used to configure EAP-SIM to require three # challenges (by default, it accepts 2 or 3) # result_ind=1 can be used to enable EAP-SIM and EAP-AKA to use # protected result indication. # 'crypto_binding' option can be used to control PEAPv0 cryptobinding # behavior: # * 0 = do not use cryptobinding (default) # * 1 = use cryptobinding if server supports it # * 2 = require cryptobinding # EAP-WSC (WPS) uses following options: pin= or # pbc=1. # phase2: Phase2 (inner authentication with TLS tunnel) parameters # (string with field-value pairs, e.g., "auth=MSCHAPV2" for EAP-PEAP or # "autheap=MSCHAPV2 autheap=MD5" for EAP-TTLS) # # TLS-based methods can use the following parameters to control TLS behavior # (these are normally in the phase1 parameter, but can be used also in the # phase2 parameter when EAP-TLS is used within the inner tunnel): # tls_allow_md5=1 - allow MD5-based certificate signatures (depending on the # TLS library, these may be disabled by default to enforce stronger # security) # tls_disable_time_checks=1 - ignore certificate validity time (this requests # the TLS library to accept certificates even if they are not currently # valid, i.e., have expired or have not yet become valid; this should be # used only for testing purposes) # tls_disable_session_ticket=1 - disable TLS Session Ticket extension # tls_disable_session_ticket=0 - allow TLS Session Ticket extension to be used # Note: If not set, this is automatically set to 1 for EAP-TLS/PEAP/TTLS # as a workaround for broken authentication server implementations unless # EAP workarounds are disabled with eap_workarounds=0. # For EAP-FAST, this must be set to 0 (or left unconfigured for the # default value to be used automatically). # tls_disable_tlsv1_1=1 - disable use of TLSv1.1 (a workaround for AAA servers # that have issues interoperating with updated TLS version) # tls_disable_tlsv1_2=1 - disable use of TLSv1.2 (a workaround for AAA servers # that have issues interoperating with updated TLS version) # # Following certificate/private key fields are used in inner Phase2 # authentication when using EAP-TTLS or EAP-PEAP. # ca_cert2: File path to CA certificate file. This file can have one or more # trusted CA certificates. If ca_cert2 and ca_path2 are not included, # server certificate will not be verified. This is insecure and a trusted # CA certificate should always be configured. # ca_path2: Directory path for CA certificate files (PEM) # client_cert2: File path to client certificate file # private_key2: File path to client private key file # private_key2_passwd: Password for private key file # dh_file2: File path to DH/DSA parameters file (in PEM format) # subject_match2: Substring to be matched against the subject of the # authentication server certificate. # altsubject_match2: Substring to be matched against the alternative subject # name of the authentication server certificate. # # fragment_size: Maximum EAP fragment size in bytes (default 1398). # This value limits the fragment size for EAP methods that support # fragmentation (e.g., EAP-TLS and EAP-PEAP). This value should be set # small enough to make the EAP messages fit in MTU of the network # interface used for EAPOL. The default value is suitable for most # cases. # # ocsp: Whether to use/require OCSP to check server certificate # 0 = do not use OCSP stapling (TLS certificate status extension) # 1 = try to use OCSP stapling, but not require response # 2 = require valid OCSP stapling response # # EAP-FAST variables: # pac_file: File path for the PAC entries. wpa_supplicant will need to be able # to create this file and write updates to it when PAC is being # provisioned or refreshed. Full path to the file should be used since # working directory may change when wpa_supplicant is run in the # background. Alternatively, a named configuration blob can be used by # setting this to blob:// # phase1: fast_provisioning option can be used to enable in-line provisioning # of EAP-FAST credentials (PAC): # 0 = disabled, # 1 = allow unauthenticated provisioning, # 2 = allow authenticated provisioning, # 3 = allow both unauthenticated and authenticated provisioning # fast_max_pac_list_len= option can be used to set the maximum # number of PAC entries to store in a PAC list (default: 10) # fast_pac_format=binary option can be used to select binary format for # storing PAC entries in order to save some space (the default # text format uses about 2.5 times the size of minimal binary # format) # # wpa_supplicant supports number of "EAP workarounds" to work around # interoperability issues with incorrectly behaving authentication servers. # These are enabled by default because some of the issues are present in large # number of authentication servers. Strict EAP conformance mode can be # configured by disabling workarounds with eap_workaround=0. # Station inactivity limit # # If a station does not send anything in ap_max_inactivity seconds, an # empty data frame is sent to it in order to verify whether it is # still in range. If this frame is not ACKed, the station will be # disassociated and then deauthenticated. This feature is used to # clear station table of old entries when the STAs move out of the # range. # # The station can associate again with the AP if it is still in range; # this inactivity poll is just used as a nicer way of verifying # inactivity; i.e., client will not report broken connection because # disassociation frame is not sent immediately without first polling # the STA with a data frame. # default: 300 (i.e., 5 minutes) #ap_max_inactivity=300 # DTIM period in Beacon intervals for AP mode (default: 2) #dtim_period=2 # Beacon interval (default: 100 TU) #beacon_int=100 # disable_ht: Whether HT (802.11n) should be disabled. # 0 = HT enabled (if AP supports it) # 1 = HT disabled # # disable_ht40: Whether HT-40 (802.11n) should be disabled. # 0 = HT-40 enabled (if AP supports it) # 1 = HT-40 disabled # # disable_sgi: Whether SGI (short guard interval) should be disabled. # 0 = SGI enabled (if AP supports it) # 1 = SGI disabled # # disable_ldpc: Whether LDPC should be disabled. # 0 = LDPC enabled (if AP supports it) # 1 = LDPC disabled # # ht40_intolerant: Whether 40 MHz intolerant should be indicated. # 0 = 40 MHz tolerant (default) # 1 = 40 MHz intolerant # # ht_mcs: Configure allowed MCS rates. # Parsed as an array of bytes, in base-16 (ascii-hex) # ht_mcs="" // Use all available (default) # ht_mcs="0xff 00 00 00 00 00 00 00 00 00 " // Use MCS 0-7 only # ht_mcs="0xff ff 00 00 00 00 00 00 00 00 " // Use MCS 0-15 only # # disable_max_amsdu: Whether MAX_AMSDU should be disabled. # -1 = Do not make any changes. # 0 = Enable MAX-AMSDU if hardware supports it. # 1 = Disable AMSDU # # ampdu_factor: Maximum A-MPDU Length Exponent # Value: 0-3, see 7.3.2.56.3 in IEEE Std 802.11n-2009. # # ampdu_density: Allow overriding AMPDU density configuration. # Treated as hint by the kernel. # -1 = Do not make any changes. # 0-3 = Set AMPDU density (aka factor) to specified value. # disable_vht: Whether VHT should be disabled. # 0 = VHT enabled (if AP supports it) # 1 = VHT disabled # # vht_capa: VHT capabilities to set in the override # vht_capa_mask: mask of VHT capabilities # # vht_rx_mcs_nss_1/2/3/4/5/6/7/8: override the MCS set for RX NSS 1-8 # vht_tx_mcs_nss_1/2/3/4/5/6/7/8: override the MCS set for TX NSS 1-8 # 0: MCS 0-7 # 1: MCS 0-8 # 2: MCS 0-9 # 3: not supported # Example blocks: # Simple case: WPA-PSK, PSK as an ASCII passphrase, allow all valid ciphers network={ ssid="simple" psk="very secret passphrase" priority=5 } # Same as previous, but request SSID-specific scanning (for APs that reject # broadcast SSID) network={ ssid="second ssid" scan_ssid=1 psk="very secret passphrase" priority=2 } # Only WPA-PSK is used.
