Unable to connect to wireless usb out of bridged mode in VMware

**Damon Jones** · 04-17-2010, 03:15 PM

Hello forum,

I have learned that this forum only helps individuals who help themselves.I'm going to show you all the steps I made to try to get this problem resolved via, google, back track 4 and linux forums.

VMware
Backtrack 4 Final
Belkin USB Wireless F5D9050
WRT54G IP address: 192.168.1.1 wpa2

First Step I made was configure my wireless interfaces nano etc/network/interfaces

Code:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto wlan0
iface wlan0 inet dhcp
wireless-essid Bain's
wireless-key lakers313

Second step start networking etc/init.d/networking start

Code:

Configuring network interfaces...done.

Third step ran a scan on my interface wlano iwlist wlan0 scan

Code:

wlan0     Scan completed :

I also ran a airmon-ng

Code:

Interface       Chipset         Driver

wlan0           Ralink 2573 USB rt73usb - [phy0]

I ran a test on my wireless usb aireplay-ng -9 mon0

Code:

10:57:46  Trying broadcast probe requests...
10:57:48  No Answer...
10:57:48  Found 1 AP

10:57:48  Trying directed probe requests...

10:57:50  Injection is working!

When I take my vmware out of bridged mode I'm unable to connect to the internet.

This is what I want to do, I would like to run my BT4 on my hard drive vs. running it on Vmware. I get a faster response from BT4 on my hardrive and everything works extremely better on my hard drive. But before I start doing that I need to get BT4 to be able to network without being in bridged mode on Vmware.

I hate that I had to come in here to ask for help, I really tried looking for the answer all week, this is my last resort. Hopfully this post can end up being a sticky to help others in the forum once I get it working.

Thanks

Other than your wlan0 actually seeing the networks, have you verified if it is in fact connected? Being that you've scaned using your wireless card I'll presume that you have connected it to the guest OS (being BT4). To verify wireless connection use ifconfig wlan0 and iwconfig wlan0 commands. If the ifconfig doesn't return an IP address in your address range then it is not connected. If so then search on wpa_supplicant and try to configure it manualy.

**Damon Jones** · 04-17-2010, 05:29 PM

Ok ifconfig wlan0

Code:

ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr 00:1c:df:d9:ad:50
          BROADCAST MULTICAST  MTU:1500  Metric:1

          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

iwconfig

Code:

iwconfig wlan0

          Mode:Managed  Frequency:2.417 GHz  Access Point: Not-Associated

          Encryption key:off

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

I'm stuck!

I was able to get into the wpa_passphrase:
root@bt:~# wpa_passphrase ssid wpapassphrase

Code:

network={
        ssid="ssid"
        #psk="wpapassphrase"
        psk=8d8c402f13e5c8d3eed3e3865f2171832ec3b0f814aae7097e9ca009c12b5dfb
}

I made a folder in my root /etc/wpa_supplicant and pasted this into it:

Code:

wpa_passphrase ssid wpapassphrase
network={
        ssid="Bain's"
        #psk="lakers313"
        psk=8d8c402f13e5c8d3eed3e3865f2171832ec3b0f814aae7097e9ca009c12b5dfb
	key_mgmt=WPA-PSK
	proto=WPA
}

After that i typed
root@bt:~# ifconfig wlan0 up
root@bt:~# ifconfig wlan0

Code:

wlan0     Link encap:Ethernet  HWaddr 00:1c:df:d9:ad:50
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

I still was unable to get the IP address to show, still now able to get on the internet when now in bridged mode.
Any other suggestions?

**mfBaranian** · 04-18-2010, 05:30 PM

Yeah you're close, but should read up on wpa_supplicant.
Here are the steps to manually configure your wireless card for a wpa connection.

Paste the below written code into a file named wpa_supplicant.conf (in a let's say /root/wpa/wpa_supplicant.conf).
It doesn't matter where it's placed, I am used to having a wpa folder on my desktop so it's easier for me to manage my wireless connections.

Code:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1

network={
ssid="Bain's"
proto=WPA
key_mgmt=WPA-PSK
pairwise=TKIP
psk="lakers313"
}

Then in terminal

wpa_supplicant -i wlan0 -c /root/wpa/wpa_supplicant.conf
New terminal (or tab)
dhclient wlan0

Now you should get an ip address and the connection should be established.

**Damon Jones** · 04-18-2010, 08:02 PM

I have fixed the problem!
1. You have to connect to your Wicd Manager
2. Check to see what networks are available in your area.
3. Connect to that network and put in the password
4. Run a ifconfig wlan0 ( you should now see an ip address in there!)

This is weird, after I spent 2 days trying to get my Wicd working I ran into a problem after reseting my backtrack 4 final.

Iwlist will not scan wlan0! I need it to scan in order to get Wicd to recognize available networks!

SEE! It sees that I have a network open in airodump-ng but for some reason it will not do a iwlist scan so Wicd can be available for me to use my wireless usb online. If anyone has any suggestions as to what may be the problem and can lead me in the right direction this will be well appreciated.

Thanks

**mfBaranian** · 04-19-2010, 08:46 AM

Yes, that's the GUI way

**mfBaranian** · 04-19-2010, 09:02 AM

I seem to be following you around

(not intentionally)
To see if the interface is up use ifconfig (only ifconfig with no interface assignments or flags). If it is it will be listed. The iwlist command stated that the network (in this case the interface) is down.
So,

Code:

ifconfig wlan0 up
iwlist wlan0 scan

**Archangel-Amael** · 04-19-2010, 03:58 PM

merged so others can follow along, better provide assistance.

**Damon Jones** · 04-20-2010, 09:55 PM

Ok I tried a few things.

Code:

root@bt:/# ifconfig wlan0 up
root@bt:/# iwlist wlan0 scan
wlan0     Failed to read scan data : Resource temporarily unavailable

Then tried it again.

Code:

root@bt:/# iwlist wlan0 scan
wlan0     Interface doesn't support scanning : Device or resource busy

For some reason the gui Wicd doesn't want to show the scans, so I guess I have to use the wpa_supplicant. Man, I hate that but at least i'm learning something new.

If you have anymore ideas to get the Wicd gui and getting the wlan0 to scan would be cool! I would appreciate it.

Thanks
Damon Jones

I did the wpa_supplicant.conf file this is the results:

Code:

wpa_supplicant -i wlan0 -c /root/wpa/wpa_supplicant.conf

I don't understand this, everything was working good 1 day ago before I rebooted my new BT4 Final, and I didn't change anything.

For some odd reason, the wlan0 will not scan, wicd won't show any wireless networks but airodump-ng shows all the networks on the system.

OK, i was able to get is scanning again.

1. I had to reset the Backtrack 4 Final around 40 times! Just to get it to scan my F5D9050 Belkin usb adaptor, is it my wireless adaptor thats causing this or is it BT4 Final. The device works out the box, I need something that works when I need it to work, not when it wants too!

Can someone tell me whats wrong, I hope its just the wireless usb instead of BT4 Final because I really like BT4 Final.

I'm kinda scared to turn off the my computer because it took me so long to get my wireless card to scan, i don't want it to disconnect.

Once it's scanning i'm able to do everything that BT4 has to offer.
