NAME

     hostapd.conf -- configuration file for hostapd(8) utility


DESCRIPTION

     The hostapd.conf utility is an authenticator for IEEE 802.11 networks.
     It provides full support for WPA/IEEE 802.11i and can also act as an IEEE
     802.1X Authenticator with a suitable backend Authentication Server (typi-
     cally FreeRADIUS).

     The configuration file consists of global parameters and domain specific
     configuration:
           ·   IEEE 802.1X-2004
           ·   RADIUS client
           ·   RADIUS authentication server
           ·   WPA/IEEE 802.11i


GLOBAL PARAMETERS

     The following parameters are recognized:

     interface
             Interface name.  Should be set in ``hostap'' mode.

     debug   Debugging mode: 0 = no, 1 = minimal, 2 = verbose, 3 = msg dumps,
             4 = excessive.

     dump_file
             Dump file for state information (on SIGUSR1).

     ctrl_interface
             The pathname of the directory in which hostapd(8) creates UNIX
             domain socket files for communication with frontend programs such
             as hostapd_cli(8).

     ctrl_interface_group
             A group name or group ID to use in setting protection on the con-
             trol interface file.  This can be set to allow non-root users to
             access the control interface files.  If no group is specified,
             the group ID of the control interface is not modified and will,
             typically, be the group ID of the directory in which the socket
             is created.

IEEE 802.1X-2004 PARAMETERS
     The following parameters are recognized:

     ieee8021x
             Require IEEE 802.1X authorization.

     eap_message
             Optional displayable message sent with EAP Request-Identity.

     wep_key_len_broadcast
             Key lengths for broadcast keys.

     wep_key_len_unicast
             Key lengths for unicast keys.

     wep_rekey_period
             Rekeying period in seconds.

     eapol_key_index_workaround
             EAPOL-Key index workaround (set bit7) for WinXP Supplicant.

     eap_reauth_period
             EAP reauthentication period in seconds.  To disable reauthentica-
             tion, use ``0''.


RADIUS CLIENT PARAMETERS

     The following parameters are recognized:

     own_ip_addr
             The own IP address of the access point (used as NAS-IP-Address).

     nas_identifier
             Optional NAS-Identifier string for RADIUS messages.

     auth_server_addr, auth_server_port, auth_server_shared_secret
             RADIUS authentication server parameters.  Can be defined twice
             for secondary servers to be used if primary one does not reply to
             RADIUS packets.

     acct_server_addr, acct_server_port, acct_server_shared_secret
             RADIUS accounting server parameters.  Can be defined twice for
             secondary servers to be used if primary one does not reply to
             RADIUS packets.

     radius_retry_primary_interval
             Retry interval for trying to return to the primary RADIUS server
             (in seconds).

     radius_acct_interim_interval
             Interim accounting update interval.  If this is set (larger than
             0) and acct_server is configured, hostapd(8) will send interim
             accounting updates every N seconds.


RADIUS AUTHENTICATION SERVER PARAMETERS

     The following parameters are recognized:

     radius_server_clients
             File name of the RADIUS clients configuration for the RADIUS
             server.  If this is commented out, RADIUS server is disabled.

     radius_server_auth_port
             The UDP port number for the RADIUS authentication server.

     radius_server_ipv6
             Use IPv6 with RADIUS server.

WPA/IEEE 802.11i PARAMETERS
     The following parameters are recognized:

     wpa     Enable WPA.  Setting this variable configures the AP to require
             WPA (either WPA-PSK or WPA-RADIUS/EAP based on other configura-
             tion).

     wpa_psk, wpa_passphrase
             WPA pre-shared keys for WPA-PSK.  This can be either entered as a
             256-bit secret in hex format (64 hex digits), wpa_psk, or as an
             ASCII passphrase (8..63 characters) that will be converted to
             PSK.  This conversion uses SSID so the PSK changes when ASCII
             passphrase is used and the SSID is changed.

     wpa_psk_file
             Optionally, WPA PSKs can be read from a separate text file (con-
             taining a list of (PSK,MAC address) pairs.

     wpa_key_mgmt
             Set of accepted key management algorithms (WPA-PSK, WPA-EAP, or
             both).

     wpa_pairwise
             Set of accepted cipher suites (encryption algorithms) for pair-
             wise keys (unicast packets).  See the example file for more
             information.

     wpa_group_rekey
             Time interval for rekeying GTK (broadcast/multicast encryption
             keys) in seconds.

     wpa_strict_rekey
             Rekey GTK when any STA that possesses the current GTK is leaving
             the BSS.

     wpa_gmk_rekey
             Time interval for rekeying GMK (master key used internally to
             generate GTKs (in seconds).
