# Interface for separate control program. If this is specified, hostapd
# will create this directory and a UNIX domain socket 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 hostapd processes/interfaces can be run at the same time if more
# than one interface is used.
# /var/run/hostapd is the recommended directory for sockets and by default,
# hostapd_cli will use it when trying to connect with hostapd.
ctrl_interface=/var/run/hostapd

# 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 hostapd 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, hostapd 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.
#
# This variable can be a group name or gid.

#deny_mac_file=/etc/hostapd.deny

# IEEE 802.11 specifies two authentication algorithms. hostapd can be

# should be used with IEEE 802.1X.
# Bit fields of allowed authentication algorithms:

# Optional displayable message sent with EAP Request-Identity. The first \0

# is only used by one station.
#use_pae_group_addr=1

##### Integrated EAP server ###################################################

# Optionally, hostapd can be configured to use an integrated EAP server
# to process EAP authentication locally without need for an external RADIUS
# server. This functionality can be used both as a local authentication server
# for IEEE 802.1X/EAPOL and as a RADIUS server for other devices.

# Use integrated EAP server instead of external RADIUS authentication
# server. This is also needed if hostapd is configured to act as a RADIUS
# authentication server.

#server_cert=/etc/hostapd.server.pem

# Private key matching with the server certificate for EAP-TLS/PEAP/TTLS
# This may point to the same file as server_cert if both certificate and key
# are included in a single file. PKCS#12 (PFX) file (.p12/.pfx) can also be
# used by commenting out server_cert and specifying the PFX file as the
# private_key.
#private_key=/etc/hostapd.server.prv

# Passphrase for private key
#private_key_passwd=secret passphrase

# Enable CRL verification.
# Note: hostapd does not yet support CRL downloading based on CDP. Thus, a
# valid CRL signed by the CA is required to be included in the ca_cert file.
# This can be done by using PEM format for CA certificate and CRL and
# concatenating these into one file. Whenever CRL changes, hostapd needs to be
# restarted to take the new CRL into use.
# 0 = do not verify CRLs (default)
# 1 = check the CRL of the user certificate
# 2 = check all CRLs in the certificate path
#check_crl=1

# Interim accounting update interval
# If this is set (larger than 0) and acct_server is configured, hostapd will

# possible Acct-Interim-Interval attribute in Access-Accept message. Thus, this
# value should not be configured in hostapd.conf, if RADIUS server is used to
# control the interim interval.
# This value should not be less 600 (10 minutes) and must not be less than
# 60 (1 minute).
#radius_acct_interim_interval=600


##### RADIUS authentication server configuration ##############################

##### WPA/IEEE 802.11i configuration ##########################################

# Enable WPA. Setting this variable configures the AP to require WPA (either
# WPA-PSK or WPA-RADIUS/EAP based on other configuration). For WPA-PSK, either
# wpa_psk or wpa_passphrase must be set and wpa_key_mgmt must include WPA-PSK.
# For WPA-RADIUS/EAP, ieee8021x must be set (but without dynamic WEP keys),
# RADIUS authentication server must be configured, and WPA-EAP must be included
# in wpa_key_mgmt.
# This field is a bit field that can be used to enable WPA (IEEE 802.11i/D3.0)
# and/or WPA2 (full IEEE 802.11i/RSN):
# bit0 = WPA
# bit1 = IEEE 802.11i/RSN (WPA2) (dot11RSNAEnabled)
#wpa=1

# 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.

# Optionally, WPA PSKs can be read from a separate text file (containing list

# TKIP = Temporal Key Integrity Protocol [IEEE 802.11i/D7.0]
# Group cipher suite (encryption algorithm for broadcast and multicast frames)
# is automatically selected based on this configuration. If only CCMP is
# allowed as the pairwise cipher, group cipher will also be CCMP. Otherwise,
# TKIP will be used as the group cipher.

# Space separated list of interfaces from which pre-authentication frames are

# interface that are used for connections to other APs. This could include
# wired interfaces and WDS links. The normal wireless data interface towards
# associated stations (e.g., wlan0) should not be added, since
# pre-authentication is only used with APs other than the currently associated
# one.
