Hostapd and WPS

Installing and Using OpenWrt
1

Hi guys,

I’m trying to enable WPS on an Omega2 running Onion OS (based on OpenWrt-18.06) for a project I’m working on (it won’t be triggered by a button, so apparently a little more secure). There’s quite a bit of information online on how to do this for OpenWrt, basically you:

  • Add option wps_pushbutton '1 ' to a config wifi-iface section that is configured for WPA2-PSK in /etc/config/wireless
  • opkg update
  • opkg remove wpad-mini
  • opkg install wpad hostapd-utils
  • reboot

I’ve worked out that before running the above, the lede-project repos need to be re-enabled for OPKG, by modifying the /etc/opkg/distfeeds.conf file, which is fine.

However, when I run: hostapd_cli wps_pbc , I get “Failed to connect to hostapd - wpa_ctrl_open: No such file or directory”.

I’ve read that problems can be caused by the /etc/hostapd/hostapd.conf file. However, I’m missing the whole /etc/hostapd directory…

Would someone be able to shine some light on this for me? Or point me in the right direction.

Thanks,

Oli

Just found out you can get hostapd to show more debug messages, this is what I'm currently getting:

root@Omega-92CA:/etc/config# hostapd -d /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
nl80211: 'nl80211' generic netlink not found
Failed to initialize driver 'nl80211'
wlan0: interface state UNINITIALIZED->DISABLED
wlan0: AP-DISABLED 
wlan0: CTRL-EVENT-TERMINATING 
hostapd_free_hapd_data: Interface wlan0 wasn't started

And this is my hostapd.conf file:

interface=wlan0
bridge=br0
country_code=AUS
ctrl_interface=wlan0
ctrl_interface_group=0
ssid=KITT
hw_mode=g
channel=1
wpa=3
wpa_passphrase=georgeisyourfriend
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
beacon_int=100
auth_algs=3
macaddr_acl=0
wmm_enabled=1
eap_reauth_period=360000000
