    <para>Hostapd is a daemon required for setting up a wireless access point, it supports
    WEP, WPA and WPA2 encryption and can optionally use EAP for authentification, but since
    this feature requires OpenSSL only basic WEP/WPA/WPA2 encryption will be compiled here.

    <para os="a">By default only a very basic hostapd is made, but hostapd supports a lot of other options as well. Write a basic config file for hostap:</para>

<screen os="b"><userinput>
cd hostapd; cat &gt; .config &lt;&lt; EOF
<literal># Support for nl80211 driver
CONFIG_DRIVER_NL80211=y
# Use v2.0 of the netlink appi
CFLAGS += -DCONFIG_LIBNL20
LDFLAGS += -lnl-genl

CONFIG_RSN_PREAUTH=y

# PeerKey handshake for Station to Station Link (IEEE 802.11e DLS)
CONFIG_PEERKEY=y
# Support draft ieee 802.11n
CONFIG_IEEE80211N=y

# Remove debugging code that is printing out debug messages to stdout.
# This can be used to reduce the size of the hostapd considerably if debugging
# code is not needed.
