eth0 is the ethernet interface...
I was going to play around with my wireless since I hadn't done any wireless cracking, or even tried to do any wireless cracking, with my HP netbook. So I opened up a terminal and this is what I got.
I'm not too sure what exactly I'm supposed to do here. BT4 is still kind of new to me although I use it as my netbook's primary OS. I'm positive that eth0 is my wireless interface, since wireless is all I use for my netbook, and this is the first time I've seen any Linux distro call a wireless interface by eth0. Could that be part of my problem?Code:root@HP-Mini:~# airmon-ng start eth0 Interface Chipset Driver eth0 Unknown wl (monitor mode enabled) root@HP-Mini:~# airodump-ng eth0 ioctl(SIOCSIWMODE) failed: Invalid argument ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211, ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead. Make sure RFMON is enabled: run 'airmon-ng start eth0 <#>' Sysfs injection support was not found either.
to see what interfaces are available. One of them should be your wireless interface if everything is configured properly. I believe the name of it changes based on your wireless card. Mine for example appears as wlan0. If you cant figure it out, post the output of ifconfig here, and someone will be able to assist you further. Once you have identified it, you can try something like
airmon-ng start <enter wifi interface>
This will create a new interface called mon0, which is your interface that you can now use to monitor wireless networks. You could then go on to type
to get information about the wireless networks within range of your computer.
Hopefully that will get you started. Look around the forum for tutorials on using these tools. Also, if you google any of those tools, you will find plenty of information on them.
This is what I get from ifconfig while I'm connected to my wireless network:
And this is my iwconfig output:Code:root@HP-Mini:~# ifconfig eth0 Link encap:Ethernet HWaddr 00:25:56:5c:71:8a inet addr:192.168.2.2 Bcast:192.168.2.255 Mask:255.255.255.0 inet6 addr: fe80::225:56ff:fe5c:718a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:194 errors:0 dropped:0 overruns:0 frame:460 TX packets:155 errors:10 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:106675 (106.6 KB) TX bytes:30083 (30.0 KB) Interrupt:16 Base address:0xc000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:4 errors:0 dropped:0 overruns:0 frame:0 TX packets:4 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:200 (200.0 B) TX bytes:200 (200.0 B)

That's strange that your wireless is showing up as eth0. I'm no Ubuntu guru, but I'll try and read up on the issue. Maybe one of the more experienced members can shed some light on this.
This is a strange problem. Your HP Netbook has a dedicated ethenet port and WiFi, correct? I looked online and most HP netbooks have both.
Try shutting down the WiFi, and then turning it back on with these commands:
And then doing the iwconfig command after that. Report back here...Code:airmon-ng stop eth0 airmon-ng start eth0
You. Are. Doing. It. Wrong.

Ok, I'm truly stumped here.
BT4 should distinguish between your Netbook's wired ethernet port and its WiFi port. Clearly it is not doing this. It may be a limitation of the tools or the Linux kernel, I cannot be sure. If anybody else has the same kind of Netbook, please try this out.
You are left with seemingly one option: Find yourself an external USB WiFi dongle, plug it in, and see if iwconfig recognizes it. Then the airmon-ng stop and start commands should work, and you should make some progress.
Sorry I cannot be more helpful. Truly a strange problem.

I have a USB card laying around here somewhere. I don't think BackTrack supports it though. Actually, I don't think I've seen any distro that supports it. I'll test it out and report back.
EDIT: I did some reading around real quick on wireless with BackTrack. The thing I was reading said that even though eth0 is usually dedicated to your wired port, it sometimes is used for your wireless card and that the name your card gets is based on your chipset. It then gave a few examples of various names for wireless cards that you might see. Since iwconfig shows "IEEE 802.11bg" that would mean that it recognizes eth0 as wireless, right? I'm no expert though so I'm just taking a guess here.
