I've only got the one laptop so I can't answer that question. I may have to live boot into my Kali DVD and see if it'll work under Kali.

It's been a few months since I last played with my RTL-SDR and since then I've moved to Ubuntu MATE and IIRC it was working under Ubuntu MATE but now it's not working. I get this error message:
Kernel driver is active, or device is claimed by second instance of librtlsdr.
In the first case, please either detach or blacklist the kernel module
(dvb_usb_rtl28xxu), or enable automatic detaching at compile time.
usb_claim_interface error -6
FATAL: Failed to open rtlsdr device.
Trying to fill up 1 missing channel(s) with null source(s).
This is being done to prevent the application from crashing
due to gnuradio bug #528.

what(): Error in function boost::math::round<f>(f): Value -inf can not be represented in the target integer type.

Not really sure what's going on. I'd like to figure it out so I can get it working again. Any ideas? Thanks.

I've used UNetbootin lots of times to make up a Live USB with Kali and it's always worked fine. Sometimes with large Distros like Kali it takes a while as the files extract to the USB, I've had some Distros stick at certain percentage for quite a while before they extracted and moved to the next files. Most of the time the Distro will either have the big files at the start or end of the .iso, sometimes, very rarely it'll be in the middle. I'd say to give it another try and just be patient, depending on your computer it may take a few minutes to get the USB stick made up.

Recently moved over to Ubuntu MATE' and needed to get my Gqrx on. One of the guys over at the Ubuntu form gave me this link:
clicked the Ubuntu icon and let the software center do the rest and now I've got Gqrx on my Ubuntu install. Go into Terminal and type "gqrx" to start it and Bob's your mom's brother. Just thought I'd share for anyone else using Ubuntu and wanting Gqrx to play with their SDR dongle.
-
Gqrx works a lot like SDR#, give it a try, you just may like it.
-
Don't know if this would work but you can get Android x86 and install it to a PC or even a USB stick(with persistence no less) and use it to run Android apps. I have in installed on a little SanDisk Cruiser Fit(little USB 'nub') that I use with an app called Piston and my OBD II Bluetooth adapter to read codes and get info from my car. Works like a charm. Here's a link for Android x86.

You can scroll down to the latest 4.4 for download unless you want something earlier.
-
Like I said, if you want something that'll take up less hard drive space you can install Manjaro and get Gqrx from the Repos through Octopi or PacmanXG and it's easy as pie to do. I just didn't need all those extra tools that Kali had so that's the main reason I moved to something else. If you can get use out of em' then by all means, do the Kali install and set up an Admin account to run it from and it'll be just like any other Debian Distro all be it one LARGE Distro.
-
I ran Kali 1.0.7 for a while and used the pre-installed Gqrx to get my SDR on. Just make sure you go into settings and set up an Admin account so you're not running Kali as root then log into that account and you should be good to go just like running any other Debian based Distro.
Of course if you want to free up some hard drive space(Kali eats up a lot of it IMHO) you can move to something like Manjaro and get Gqrx from the Community Repos and have the same SDR support as in Kali. Also, IIRC, any of the Debian Testing Distros would have Gqrx in the Repos now as well.

I have a couple cordless phones, one in the 900MHz range and one in the 2.4GHz range that are just sitting collecting dust. I no longer have wired phone service so there's no way to use them unless someone knows a way to set them up for use with my DSL so I can make VoIP calls with them. I figured the 2.4GHz one would be easier since it's on the same freq. as my Router/Modem but I really know nothing about this kind of stuff. Anyone who does, I'd appreciate any info or links you could provide. Thanks.
-
Thanks for the link. I'm thinking that I need to go into Terminal and set my wifi card to monitor mode, i.e. mon0 in order for Wireshark to be able to use monitor mode, that's why it was saying "device not ready". Anyway, I'll read the link in a bit, thanks again.
-
Alright, I went into promiscuous mode and monitor mode and captured some packets. When I looked at my wifi connection drop down it had my wifi card listed but said "device not ready" but I did get some packets so where did they come from?
-
Ok so I'm able to capture my own traffic and I've figured out how to set wlan0 in Wireshark to monitor mode so that should be capturing other people local traffic from their wifi. Now I just need to know what to do with all this data,LOL. This IS something that I'm going to learn and figure out one way or the other because I think it would be a useful tool to have in my toolbox.
-
Ok, went to here:
https://wiki.archlinux.org/index.php/wireshark
Did this:
sudo gpasswd -a "ME" wireshark
did a reboot and Bob's my mom's brother.
-
Ok, so help me figure this one out. If I open WireShark from the icon in my menu list I can't capture any packets but if I open it from Terminal with "sudo wireshark" then I can capture packets but I get some warnings about how it's not good to run WireShark as root, yada, yada, yada. Anyway, can someone give me a reader's digest version of how I can set up WireShark so I can open it with the icon and have privileges to capture packets without having to run as root? I read the web page on this but it's just all so much gibberish to me, need it in simple terms please.
Setting network privileges for dumpcap
1. Ensure your linux kernel and filesystem supports File Capabilities and also you have installed necessary tools.
2. "setcap 'CAP_NET_RAW+eip CAP_NET_ADMIN+eip' /usr/sbin/dumpcap"
3. Start Wireshark as non-root and ensure you see the list of interfaces and can do live capture.
Ok, so can someone translate this for me? Yes, my Manjaro Xfce install has the capabilities but what other tools do I need?
what do I do with #2 on the list? Just type it into Terminal or something?
-
It's getting it up and running that's the problem. I see no sources to pull data from in my list.
It tells me that there are no interfaces on which a capture can be done.
-
Ok, just watched the latest HakTip where Sunbs is going over how to use WireShark and it's got me interested again so I've installed it into my Manjaro install and need to know how to set things up so I can use it.
There's no capture options coming up when I look for them. What do I need to do or add to be able to see my wifi in order to capture some packets? Thanks in advance for any help ya'll can give.

I wonder which of the 4 coax ports is the power port?
Good link for a Biquad.
http://www.engadget.com/2005/11/15/how-to-build-a-wifi-biquad-dish-antenna/
-
This may also shed some light on the subject. The front part of my Dish is called an LNB(Low Noise Block) and is basically a down converter.
http://www.satsig.net/lnb/explanation-description-lnb.htm
So I guess it converts the really high freq. from the satellite down to something we can use. I'd just like to figure out a way that we can apply this to our SDR dongles to do something cool like listen to other satellites or something.
-
I did put the array out of the the support beam and there's 4 coax outputs. I hooked a coax cable to one of the center ones and then hooked it into my dongle with the coax adapter that I have and was able to tune in a local radio station so it works as a radio antenna. Wish I knew what all the outputs were actually for, I'm sure they're tuned to different frequencies or something. I'd like to get the other dish with the dual array off of the roof as well. That'd give me this triple array and a second dual array to play around with. No reason just letting this stuff just sit there and go to waste when I might be able to do something cool with it.
P.S.
Here's what I've got to play with on the dish I've got right now.
No earthly clue as to what output does what though.
P.S.S.
Good video, I downloaded it using a Flash & Video plug-in for my Firefox browser so I've got it for future ref., thanks.

I've been watching a show on Netflix(you can probably catch it on YouTube or other places as well) called "Rocket City Rednecks" and to me it's what Hacking is all about. These guys take a bunch of "junk" and in a weekend turn it into something cool. It's amazing at how many neat things you can make with a little imagination and some parts and pieces of things you've just got laying around. Anyway, if anyone wants to watch a fun show give Rocket City Rednecks a try.

I have an old DirectTV dish that I'm not using anymore. It's one of the newer ones with the three nubs on it(Multi Satellite IIRC) and I wonder with it and my RTL-SDR dongle and a coax adapter can I wire it up and do something with it? I'll have to mount it onto a tripod and I'll need to add connector ends to the cables coming out of the board that's mounted on the dish. I guess I'd have to run the 4 coax wires into a spliter and bring it down to a single coax wire that I can hook to my coax adapter then I'd plug that into my dongle but what to do from there?? What freq. range would I need to look at and what can I pick up with a dish like this? Has anyone else messed around with and hacked an old DirectTV dish and if so is there any good web sites with info on what to do and how to do it. Anyway, thanks in advance.

An easy way that I've used for dealing with e-mail is to have a couple different accounts that I use for different things. I have my bank, credit cards, ebay, amazon, ect linked to a husmail account that I use just for those important things. Everything else like social stuff, web sites that I'm on, stuff that really doesn't matter is linked to another account. That way anything that really matters goes to an account where I can deal with it in a priority manner and anything on the other account is stuff I get to when I can get to it. HushMail has free accounts that you can sign up for and I'm sure there's a few other web-mail accounts you can also get but I've used HushMail for years and it's been rock solid so it's my current "go to". Anyway, just wanted to pass this on, probably something everyone already knows about but I just had to say it anyway.

Also, as far as GNU/Linux goes, any Distro that has the Tools you need in it's Repos(like Metasploit, WireShark,ect.) would work as well as any other. The nice thing about Kali is that they've added all the Tools for you but really Kali is just a Debian based Distro with a ton of extras. You can just as easily install Debian then add the Tools you want/need to it.
One nice thing about Linux is that you don't have to shell out your hard earned cash to get a copy like you do with Windows and you're not as prone to all those nasty viruses and malware like you would be running Windows. Mac OS-X is kind of the "lost" OS IMHO, yes, now it's Free to download and use and yes there's not a lot of viruses and stuff that mess with it but I also don't know if you can get all the packages you would want to use with it like you can with a good Linux based OS.

I've been using Linux for over a year and a half and after a lot of Distro Hoppin' I've landed on what I think is probably one of the better Linux Distros, Manjaro. I'm using the Xfce version and set to Testing Mode so I get updates every few days instead of having to wait a month like in Stable(or daily like in Unstable) Manjaro gives you all the goodness of Arch without the downside. You can use the Manjaro mirrors(i.e. Repos) that have a lot of packges ine them or the AUR that has a ton more. You use pacman which IMHO is easier to use then apt-get and the Manjaro Forums are a really great place to hang out with the Devs hanging out there as well so you can actually get in touch with the folks that take care of this Distro.
Download it and make up a Live USB or DVD and give it a look. Also, if you go the Xfce route remember that you don't have to run it the way it looks "out of the box". I moved the panel from the bottom to the top and added a 2nd panel at the bottom so it looks a lot like the MATE desktop that I was using. Also at the bottom of the link you can go to the Community versions where you can get MATE, Cinnamon, ect if you don't want Xfce or KDE.
RTL-SDR stopped working.

Thanks for the info guys. I'll give all of it a try and see if I can get it working.
Edit for addtional info.
The "sudo rmmod dvb_usb_rtl28xxu" worked to get it up and running. Guess I just need to blacklist it by by creating "rtlsdr.conf" in "/etc/modprobe.d" and putting "blacklist dvb_usb_rtl28xxu" in it. Thanks again guys.
