How to configure hostapd.conf for wps push button?

Question

I have android6.0.1 I want to enable the wps when hotspot on.

Can anyone give some ideas and give whatever changes i want to do in someother files.?

Can anyone provide any application for wps server.?

Thanks, VinothS,

Solution 1

Funny coincidence. I was looking for this, too, today for Debian. Currently I'm following:

http://ftp.netbsd.org/pub/NetBSD/NetBSD-current/src/external/bsd/wpa/dist/hostapd/README-WPS and a bit of https://w1.fi/cgit/hostap/plain/hostapd/hostapd.conf

I just needed to copy these lines:

wpa_psk_file=/home/<username>/etc/hostapd/hostapd.psk
ctrl_interface=/var/run/hostapd
eap_server=1
wps_state=2
ap_setup_locked=1
wps_pin_requests=/var/run/hostapd.pin-req
device_name=USB2.0 WLAN
manufacturer=ATHEROS
model_name=WAP
model_number=123
serial_number=12345
device_type=6-0050F204-1
os_version=01020300
config_methods=label display push_button keypad

into my hostapd.conf file. I created a custom one for myself in ~/etc/hostapd.conf, but normally there is one in /etc/hostapd/hostapd.conf. In your case you might have to change device_type. I tried to mostly verify the information like manufacturer, ... but I don't think they are that important. I was able to find manufacturer and serial number using lsusb and then sudo lsusb -v -s 5:7 (the numbers after -s are the bus and device numbers shown by lsusb)

After that I restarted hostapd with the new configuration file:

sudo pkill hostapd
sudo bash -c "nohup hostapd '$HOME/etc/hostapd/hostapd.conf' > '$HOME/nohupHostapd.out'" &

and did a quick sudo hostapd_cli wps_pbc and then was able to connect the printer using WPS.

Needs to add the string (wps_state, eap_server) in the following files,

system/netd/server/SoftapController.cpp

int SoftapController::setSoftap(int argc, char *argv[]) {
int hidden  = 0;
int channel = AP_CHANNEL_DEFAULT;

int wps_state = 2;

if (argc < 5) {
  ALOGE("Softap set is missing arguments. Please use:");
  ALOGE("softap <wlan iface> <SSID> <hidden/broadcast> <channel> <wpa2?-psk|open> <passphrase>");
  return ResponseCode: : CommandSyntaxError;
}

if (!strcasecmp(argv[4], "hidden"))
  hidden = 1;

if (argc >= 5) {
  channel = atoi(argv[5]);
if (channel <= 0)
  channel = AP_CHANNEL_DEFAULT;
}

std::string wbuf(StringPrintf("interface=%s\n"
  "driver=nl80211\n"
  "ctrl_interface=/data/misc/wifi/hostapd\n"
  "ssid=%s\n"
  "channel=%d\n"
  "ieee80211n=1\n"
  "hw_mode=%c\n"
  "ignore_broadcast_ssid=%d, eap_server = 1, wps_state = %d\n",
  argv[2], argv[3], channel, (channel <= 14) ? 'g' : 'a', hidden,wps_state));

std::string fbuf;
if (argc > 7) {
char psk_str[2*SHA256_DIGEST_LENGTH+1];
if (!strcmp(argv[6], "wpa-psk")) {
  if (!generatePsk(argv[3], argv[7], psk_str)) {
    return ResponseCode: : OperationFailed;
  }
  fbuf = StringPrintf("%swpa=3\nwpa_pairwise=TKIP CCMP\nwpa_psk=%s\n", wbuf.c_str(), psk_str);
  } else if (!strcmp(argv[6], "wpa2-psk")) {
    if (!generatePsk(argv[3], argv[7], psk_str)) {
      return ResponseCode: : OperationFailed;
    }
    fbuf = StringPrintf("%swpa=2\nrsn_pairwise=CCMP\nwpa_psk=%s\n", wbuf.c_str(), psk_str);
  } else if (!strcmp(argv[6], "open")) {
    fbuf = wbuf;
  }
} else if (argc > 6) {
  if (!strcmp(argv[6], "open")) {
    fbuf = wbuf;
  }
} else {
  fbuf = wbuf;
}

if (!WriteStringToFile(fbuf, HOSTAPD_CONF_FILE, 0660, AID_SYSTEM, AID_WIFI)) {
ALOGE("Cannot write to \"%s\": %s", HOSTAPD_CONF_FILE, strerror(errno));
  return ResponseCode::OperationFailed;
} else {
  return ResponseCode::SoftapStatusResult;
}

Testing,

hostapd_cli wps_pbc

Hi Thank you for your reply. I have the doubt now. I can not find "var/run" this one default or created automatically. And which wifi module are used? I am using wl1831. Thanks, VinothS,

[VINOTHKUMAR S]

When i try i got error like that root@sabresd_6dq:/ # hostapd_cli wps_pbc Failed to connect to hostapd - wpa_ctrl_open: No such file or directory Can you provide some ideas.? Thanks, VinothS,

[mxmlnkn]

/var/run/hostapd is created automatically. The error message Failed to connect to hostapd should only happen if you forgot the line ctrl_interface=/var/run/hostapd or if you apply the changes by restarting hostapd, see also here Note that I didn't need to add ctrl_interface_group=0 like the answers writes. If /var/run/ itself is missing, then I can't really help.Must be an android problem then. Try creating it with mkdir...

[VINOTHKUMAR S]

Hi thank you for your reply, I try everything.But, i got error root@sabresd_6dq:/system/etc/wifi # start hostapd init: Starting service 'hostapd'... root@sabresd_6dq:/system/etc/wifi # init: Service 'hostapd' (pid 2276) exited with status 1 hostapd_cli wps_pbc Failed to connect to hostapd - wpa_ctrl_open: No such file or directory Help me and give some more suggestion. Thanks, VinothS,

Having the same issue, actually. I'm on Ubuntu 16.04, will try to mkdir it, maybe that'll take care of the issue.

It is very hard to debug over the internet. My guess is, that both of you aren't doing this on your router. I have a WLAN-stick for my PC which I use to make a hotspot with which my printer then connects. I.e. it is directly connected to my PC where I configure hostapd. "failed to connect" means most likely hostapd isn't running or was configured wrong or even with the wrong config-file. E.g. check with ps aux | grep hostapd. I don't know how you start hostapd, but I do with sudo pkill hostapd and sudo bash -c "nohup hostapd '$HOME/etc/hostapd/hostapd.conf' > '$HOME/nohupHostapd.out'" &

Hi, are you try in Linux.? or Android.? Why because i was tried in Android.? May be it's work or possible in Linux. But, not sure at Android.

[mxmlnkn]

I'm using Linux. Android uses the Linux kernel and many Linux programs like hostapd, but there still might be differences, yes. I can't really test it on mine, because I haven't rooted my smartphone.

[VINOTHKUMAR S]

Hi mxmlnkn. I already have rooted phone. Do you know any possible to work in android?. And what are the important things when i try this one. I want some configuration file related to this like android.conf and hostapd.conf. and are you configured dhcpcd.conf file. and which wifi-chip you are used?

[mxmlnkn]

I'm sorry, I can't help anymore. My android skills are basically none. Stackoverflow also isn't suited for many follow-up questions. You might be better off asking in an Android forum or wait for another answer to your question if my answer isn't working for you.

[VINOTHKUMAR S]

Hi thank you for your reply. i want to what are the configuration you enabled or added with hostapd.conf and android.conf. and which wifi chip are you used.? Thanks,
