36 .Nd configuration file for
43 is an authenticator for IEEE 802.11 networks.
44 It provides full support for WPA/IEEE 802.11i and
45 can also act as an IEEE 802.1X Authenticator with a suitable
46 backend Authentication Server (typically
49 The configuration file consists of global parameters and domain
50 specific configuration:
51 .Bl -bullet -offset indent -compact
56 .\" Integrated EAP server
58 .\" IEEE 802.11f - Inter-Access Point Protocol (IAPP)
62 RADIUS authentication server
67 The following parameters are recognized:
68 .Bl -tag -width indent
75 Debugging mode: 0 = no, 1 = minimal, 2 = verbose, 3 = msg dumps, 4 =
78 Dump file for state information (on SIGUSR1).

87 .It Va ctrl_interface_group
88 A group name or group ID to use in setting protection on the
89 control interface file.
90 This can be set to allow non-root users to access the
91 control interface files.
92 If no group is specified, the group ID of the control interface
93 is not modified and will, typically, be the
94 group ID of the directory in which the socket is created.
96 .Sh IEEE 802.1X-2004 PARAMETERS
97 The following parameters are recognized:
98 .Bl -tag -width indent
100 Require IEEE 802.1X authorization.

123 .\" .It Va iapp_interface
124 .\" Interface to be used for IAPP broadcast packets
126 .Sh RADIUS CLIENT PARAMETERS
127 The following parameters are recognized:
128 .Bl -tag -width indent
130 The own IP address of the access point (used as NAS-IP-Address).
131 .It Va nas_identifier
132 Optional NAS-Identifier string for RADIUS messages.
133 .It Va auth_server_addr , auth_server_port , auth_server_shared_secret
134 RADIUS authentication server parameters.

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

141 .It Va radius_retry_primary_interval
142 Retry interval for trying to return to the primary RADIUS server (in
144 .It Va radius_acct_interim_interval
145 Interim accounting update interval.
146 If this is set (larger than 0) and acct_server is configured,
148 will send interim accounting updates every N seconds.
150 .Sh RADIUS AUTHENTICATION SERVER PARAMETERS
151 The following parameters are recognized:
152 .Bl -tag -width indent
153 .It Va radius_server_clients
154 File name of the RADIUS clients configuration for the RADIUS server.

157 The UDP port number for the RADIUS authentication server.
158 .It Va radius_server_ipv6
159 Use IPv6 with RADIUS server.
161 .Sh WPA/IEEE 802.11i PARAMETERS
162 The following parameters are recognized:
163 .Bl -tag -width indent
166 Setting this variable configures the AP to require WPA (either
167 WPA-PSK or WPA-RADIUS/EAP based on other configuration).
168 .It Va wpa_psk , wpa_passphrase
169 WPA pre-shared keys for WPA-PSK.
170 This can be either entered as a 256-bit secret in hex format (64 hex
171 digits), wpa_psk, or as an ASCII passphrase (8..63 characters) that
172 will be converted to PSK.
173 This conversion uses SSID so the PSK changes when ASCII passphrase is
174 used and the SSID is changed.
176 Optionally, WPA PSKs can be read from a separate text file (containing a
177 list of (PSK,MAC address) pairs.
