Raspberry Pi, wireless dongle, hostapd

[geordonv]

Hi, folks! I just got a Pi a few days ago, with the intent of turning it into a TOR relay when all is said and done.

I've got the Pi set up and working with both eth0 and wlan0 on my "normal" network, so I know that the hardware works. I'm running the latest Raspbian but can NOT get hosted to work right. I'm following the how to over at learning.adafruit to set up a WAP, including downloading the Adafruit-compiled hostapd. This is my hostapd.conf:

Code: Select all

interface=wlan0
driver=rtl871xdrv
ssid=Pi_AP
hw_mode=g
channel=6
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=Raspberry
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

Here is the output that I get when trying to start hostapd

Code: Select all

Configuration file: /etc/hostapd/hostapd.conf
drv->ifindex=3
l2_sock_recv==l2_sock_xmit=0x0x10ce638
+rtl871x_sta_deauth_ops, ff:ff:ff:ff:ff:ff is deauth, reason=2

rtl871x_set_key_ops
rtl871x_set_beacon_ops
rtl871x_set_hidden_ssid_ops
ioctl[RTL_IOCTL_HOSTAPD]: Invalid argument

I'm thinking that I might need a new (compatible?) driver to go with the latest raspbian, but the instructions for THAT are out of date on the adafruit website, too.

Any suggestions would be VERY appreciated

Upon further investigation, I think that something in the hostapd is what's messing me up. Here's my /etc/hostapd/hostapd.conf:

Code: Select all

interface=wlan0
driver=rtl871xdrv
ssid=Onion
hw_mode=g
channel=6
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=raspberr
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

When I run sudo /usr/sbin/hostapd -d /etc/hostapd/hostapd.conf, this is what comes up:

Code: Select all

There seems to be an invalid argument somewhere, but I can not for the life of me figure out where it is.

Try removing this line from the conf file:

Code: Select all

ignore_broadcast_ssid=0

That seems to be where ioctl is complaining.

[geordonv]

Edited the hostapd.conf to reflect the below:

Code: Select all

interface=wlan0
driver=rtl871xdrv
ssid=Onion
hw_mode=g
channel=6
macaddr_acl=0
auth_algs=1
wpa=2
wpa_passphrase=raspberr
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

Sadly, that doesn't seem to have resolved the problem:
pi@onion-pi /var/log/privoxy $ sudo /usr/sbin/hostapd -d /etc/hostapd/hostapd.conf

[adafruit_support_mike]

Hmm.. I'll have to do some more research to see what that error means.

[ar_ken]

I'm having the very same issue.

[sk00t3r]

Add me to the list. Same exact issues. I can not figure this out either. Thank you.

[sk00t3r]

Think I got it. Download and compile the latest drivers from http://www.realtek.com.tw/downloads/dow ... Down=false Choose the RTL8188CUS.

This is what I did:

cd /tmp
sudo wget "ftp://95.130.192.218/cn/wlan/RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip" (without the quotes)
sudo unzip RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip
cd RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911
cd wpa_supplicant_hostapd
sudo tar -xvf wpa_supplicant_hostapd-0.8_rtw_r7475.20130812.tar.gz
cd wpa_supplicant_hostapd-0.8_rtw_r7475.20130812
cd hostapd
sudo make
sudo make install

sudo mv hostapd /usr/sbin/hostapd
sudo chown root.root /usr/sbin/hostapd
sudo chmod 755 /usr/sbin/hostapd

Please let me know if this workes for anyone. Thank you.

[procrastin]

driver update instructions worked for me (except for the ftp and putting a sudo in front of the tar command)

[adafruit_support_mike]

Thanks for posting the solution. I'm still not sure why the driver would need to be updated, but I'm glad to hear that it worked.

[geordonv]

Thanks, sk00t3r, for your input about compiling and installing the hostapd fresh. That has gotten me past that particular hurdle. Now I have to figure out why I'm not getting in through the dhcpd.

[Pouknouki]

Thanks for the solution, saved me !

[scofield]

Confirmed, both the problem and the solution =)

[smokeandlights]

Same problem, Same solution! thanks!

[christiangeek]

Same problem here as well, the fix worked although the FTP URL shown did not work...I had to go to the Realtek site and download manually.

Thanks to sk00t3r. Adafruit...please update the tutorial to at least link to this thread. Thanks!
