  1. I'm not sure if this is too 'movie far fetched', but is it possible to scan a small area (maybe a couple feet or more) for cell phones and see the number? Would they have to be in use at the time, or is there no possible way?

    If you wanted to be a 'bad boy' I suppose that you could interrupt cellphone coverage at a particular location forcing each cellphone to re-register to the network. If you were able to monitor the re-registration you might be able to grab the IMEA for each phone, and thus work out the appropriate phone numbers.... not exactly subtle though.

    Another way is to run a fake Cell site with the correct profile for a particular network, local phones would register to the stronger signal.

    If she really doesn't want to give you her number, then give up ;-).



  2. Looks pretty good. Can you change the color of existing pictures or just the filters on it?

    You can select an area (say the 'bonnet' or 'hood'), and then use the right-click 'Layer' 'Colours' 'Hue-Saturation' to slide the Hue to whatever you want...



  3. My idea was how easy it would be for someone to disconnect the phone and plant a device using the connection the phone is using.

    It's more or less standard practice to use a seperate VLAN for VoIP phones, that said I believe that my company's switch is configured to allow both VLAN (for IP phones) and non-VLAN should someone just plug a normal device (PC or Laptop) into the port.

    If (and that's a big if) they done it 'right', the port of the network switch should be configured to only allow the MAC address of the phone and tie it to a specific VLAN to restrict what network it can use.

    Rather than replace the phone connection, you'd be better off adding something (802.11 AP?) to it so that the 'adjustment' doesn't get noticed too quickly. Just how much would 'they' freak out if they found an AP connected to the back of the phone?



  4. That got me thinking though.


    You don't mention what type of handset was used in the Loby. If it was a 'modern' design then a lot (!!) of information might be available about the company network. For example we use Cisco 7911. Using 'Menu', 'Settings', ... you can find out a lot! Including whether the PC RJ45 is enabled or not.

    If it were properly configured then it should be possible to lock down that phone complete, best would be to lift receiver to automatically dial receptionist. From you description this is obviously not the case.



  5. Basically what i am looking for is something that is good, cheap(limited budget atm) and has low power req (hopfully want to be able to power it with solar and some batteries.

    You don't mention what band (frequency) you want to work in, or what you're hoping to do with it.

    Technically it would be illegal to operate a HAM transceiver without a license, since you suggest you are a 'nube' it would be worthwhile taking the exam first and then considering what to get,




  6. My only question before I start is in relation the the following two paragraphs:-
    You need to buy a dedicated server or a VPS package if you want to setup your own server. If you want to experiment with the server and installation it is recommended to buy a vps package from various hosts. I prefer vpslink because of their pricing. Believe it or not it is so easy to install and configure your server yourself eventhough you are new are to linux and dedicated/vps hosting.

    First download PuTTy if you are accessing your server through SSH. Just enter the IP of your server with root login to access your host. As you probably know, Webmin is a freely available server control panel and we will setup this once we have completed the LAMP server and Mail Server. Webmin makes more easier for us to fine tune our linux box.

    Am I correct in assuming this isn't at all needed, but that I should follow the rest of the instructions?

    Thanks for any advice, thought it best to ask as having to re-install all this again would be a major 'ball ache'.

    Once again, my doing this to to allow the hosting of some sites, and to be able to SSH into the server allowing the avoidance of filtering programs, from where ever I may be in the world. Finally an extra bonus would be the ability to run a mail server, running at the same time as the other features.


    The VPS they mention in the article is a 'virtual private server'. This is a VM-Wared (or the like) machine that you might have access to should you 'rent' one at an hosting company. In your system I believe that you will be using your own (real) machine on a home connection. You can ignore this paragraph.

    Putty is a good tool to access ssh servers from Windows machines.

    Webmin is a web based configuration tool, it can make setting up/administering a server a bit easier. Webmin was briefly mentioned in Linux Reality #275 (see

    On suggestion I have it to use that spare partition for a data/home partion, that way you can re-install Linux without trashing all your data.



  7. Shh..... that's 'Transcrypt Confidential' ;-)

    Fairly pricey, combined with that these would only be legal to use on Licensed 'private' frequencies.

    If you don't know about it, check out cryptophone (encrypted cell phone via GSM data calls):



  8. I am also part wolf - part human….so you really should remember me 

    Sounds like a meeting not to forget.... ;-)

    Hoping to get to HOPE this year, I'll have to see how family plans pan out.


    PS. Should be easy to spot, I'm the scruffy geek.


  9. But how would I go about feeding it into my sound card and enabling it to have TX abilities?

    For the RX side of things, just connecting audio jacks together should be OK. You may need to play with volume/record level to get something working. For TX you would need a transmitter (as scanner does not transmit) running at the appropriate frequency. I would presume that these remotes operate within a license free band (ie Part 15)

    Obviously breaking into people's houses/garages is illegal.... I can't really encourage you to actually construct something which _could_ be used as a 'break & enter' tool.



  10. A quick bit of googling and here's some more information.

    1). there is a 'security+' scheme which implements a rolling key, used on modern systems.

    2). remotes appear to work on 390MHz band.

    3). All in one chips are available, see

    4). US embassies are acting to prevent the criminals intent by blocking the 390MHz band, see



  11. I was wondering if its possible to pick up frequency signals (ex. TV remote, garage door opener) through your laptop or some additional hardware for the laptop?

    You can use a scanner (or some form of radio) feeding into the sound card of a PC/Laptop. This obviously is RX only, but using application like 'Multimon' you can recieve and decode pagers/packet radio/APRS/etc. If you have TX capability there is no reason why you couldn't do a replay attack.

    My wife's car has an in-built door opener, you can put it into learning mode to clone a third party garage door opener. I guess that this is no-different.

    I assume there there has not been a concern about security on this before, so most likely the codes would be pretty easy to clone. Unless of course they use a rolling key, in the same way that car door remotes work.



  12. Be wary if the motor has had it's heads off. Make sure they used new bolts. The factory puts 'torque-to-yeild' bolts on which means you can only torque them once. Reuse them and they'll stretch causing a blown head gasket. very ugly.

    Hmmmm..... don't tease me!!!

    Following on from PurpleJesus's excellent comments....

    Before starting engine check the rad to see if it is warm, if not you can pop the rad cap off (carefully!) to see if there's a scum on the coolant. Could signify a oil leak into coolant. Also if it's cold then you'll get a sense of the cold-start capability of the car.



  13. What exactly do you mean by spare box? Like old computer?

    The Mac is actually at a cafe that some friends and I chill at every now and then. They enable websense which blows, especially when your hanging with a buncha friends. My computer runs linux and windows. How would go about tunneling from the mac to my computer?

    You will have to have a ssh server on one end of the connection, I suggest you do this at you (Linux) end.

    To enable the ssh server on you Linux box you should install 'openssh_server', this will create the key pairs and start the service. Providing you have the appropriate ports forward so that port 22 is accessible from the internet your Mac friend would be able to log into a shell account (using Linux machine's username/password) with his ssh client.

    Once this works the Mac user can use the '-R' or '-L' options in the ssh client to enable port forwarding of particular port via the ssh link.

    If you want to enable the ssh server on the Windows machine, then I suggest you look at Cygwin which can install the ssh server as a windows service (ie. it is started when machine boots). You'll also want to confirm that the ports are forwarded through the Windows firewall.




  14. i have a pair of skull candy headphones and when i had Windows XP they worked fine but...when i try them on liunx they dont seem to work at all i tried Kmix and other things and switches on the audio mixer to get them to work and nothing is doing it and my computer has all updates in it.

    It's possible that the audio chip set actually has seperate outputs for the speakers (rear panel) and the headphone (front panel) and that in Windows the driver is being cleaver on how it manages these.

    First suggestion I would have is try 'alsamixer' on the command line. Usually has full control over all the alsa settings, the gui clients are sometimes limited to just a few parameters. Also do a 'lspci' to find out what audio hardware you actually have, you may be able to set it up better in the alsa conf files.



  15. I need advice on buying my first car...

    Also, I can spend up to only $7000.

    You seem to have quite a price differential in the cars you've selected (down to 1500). I figure that you've not been looking long and are going for 'glitz'. Not that there's anything necessarily wrong with that. If you're going to spend the whole $7000, would suggest that you figure $5000 purchase/$2000 repairs. Take some time to look around (even out of your area) so that you can see average prices/conditions for specific models. Don't jump in all excited and regret it later.

    You don't say whether you're mechanically minded, or have access to tools. Being young is a great time to learn about the mechanical side (often you'll have to).

    Happy Hunting,


    PS. I drive a Forester with a leaking head gasket, before you ask...

    PPS How come there's no snow in any of the pictures. Check when they were listed.


  16. How can you connect to a public network and knowing your secure without having to ssh to another desktop? Also what methods can be used? Enough security to login to your email without worry

    If you just mean collecting email securely, most providers will allow a 'Secure POP'/'Secure SMTP' connection using SSL. Just reconfigure your email client to use these.

    If you need to secure connect to a remote network, via a public network. SSH is good, or you can use a VPN.



  17. So many questions.... ;-)

    1). A LiveCD is a good way to try out Linux without having to install it. You will have to download an ISO image and burn to CD, if you have a Linux User Group (LUG) near you they may have a selection of distro's you could try.

    One of the most popular at present is Ubuntu. You can download from, they can even send you a CD in the post.

    2). If you decide you like what you see, installing to harddisk will improve performance. Most CD's come with an installation wizard which will resize your Windows partition and install Linux. This will enable you to 'dual boot', selecting whether to start Linux or Windows when you turn your computer on.

    3). Almost all data files (images, audio, etc) are support under Linux, the applications will recognise the 'usual' extensions. There is a slight issue with MP3 in the USA as this is a patented file format, 'pay for' codecs are available, or you can just be a rebel and download the ones that the rest of the world use.

    4). Mostly the applications which you use on Windows will not run on Linux. There are likely native Linux applications which will serve the same purpose. There are techniques for running Windows applications. Try it and see how many applications you are 'missing'.

    5). I'm not a gamer... but this might answer your question.

    6). Hardware support is MUCH better than it used to be, basically a modern Linux distribution will automatically detect and configure your hardware.




  18. A scanner is slightly more than a receiver, it normally can scan (hence the name) through a sequence of frequencies quickly looking for a signal. It normally stops when it finds one so that you can listen to it.

    A two way radio can TX and RX, but nominally only on specific frequencies.

    A mobile transceiver can TX and RX on specific frequencies, however with the event of modern electronics they can easily roll in the functionality of a scanner. (RX is easy, TX needs carefully designed electronics.)




  19. Anyone have any more info on this....

    Apparently there is a remote exploitable flaw in the Windows TCP/IP stack related to the IGMP. This means that any machine on an infected network can be affected by this, since it is a stack flaw it is NOT caught by software firewalls (MS or 3rd party).

    Patches are out so get updating, originally reported June 2006. (nothing like a tardy fix ;-).



  20. I was just wondering about buying cheap processors instead of buying a thousand dollar processor. I was hoping to get the power of these cores to run games faster. It was just a thought and it would be a neat project for me.

    If you're looking for cheap [edit: OK 'cheaper'] clustering you can go the multiple GFX card route.

    Nvidia provide an API to program arbetory code onto they cards:

    This is what the fore mentioned Acceleware ( <a href="" target="_blank"></a> ) uses in their clusters.



  21. Well my connection speed is 100mbps, im trying to figure out how to get it to 1gbps. Does the ISP have control of that?

    Are you refering to the speed of your LAN (ie. between computer and router)? If so this is dependant on your PC's network card, router and cabling between them (maybe your cable is not fully connected, 1gps requires all 4 pairs, 100mbps only needs 2). The speed of your LAN does not depend on your ISP.

    If you are refering to a 1gbps internet connection, you obviously have enough cash to hire a consultant... ;-)



  22. I've been kicking myself for not setting up VNC on my XP box pretty much since I left the house, but I'm traveling and just found out I'm going to be gone way longer than I originally thought. Theres tons of stuff I need off my desktop but I cant get to it.

    Googling remote VNC installs turned up fastpush but it seems thats just for LANs and I'm 900 miles away.

    Anyone have any suggestions on how I could install VNC (something similar and free) on my machine without being in front of it?

    Of course, but getting through the hardware firewall (router) and well configured Windows firewall might be more difficult. ;-)

    1st question has to be is there anyone who can get physical access on your behalf (even a well trained cat would do providing it isn't too busy doing prank 911 calls). If so you could get them to visit '', run the client application and let you take control of the machine to install whatever software you require. For the technically minded I believe that their app is a java version of citrix.

    Personally, despite being a free software nut, would suggest using Desktop Sharing (coupled with Rdesktop if your other machine is Linux). Seems to work much better than VNC. You'll also want to ensure that the channel is secure (VPN or something).

    Good luck,



  23. 5). If your Router supports alternate firmwares (ie. OpenWRT) you can configure more than 1 physical port (RJ45) to be the WAN. Plug 1 WAN into cable modem and the other WAN into CentosOS machine.

    Yeah, I have DD-WRT v.24 running but I don't understand what you mean.

    Do you want me to connect two machines (router and centos) in the same time to the cable modem ?

    There is nothing special (different) about the ports on the back of my router (a WRT54GL), it is purely by convention that one is for the WAN the others are for the LAN. The hardware contained within the router is simply a multi-port switch with VLAN capability.


    With OpenWRT you can assign which ports on the switch are connected to which VLAN, so effectively you can convert it into a 3 port LAN switch and a 2 port (+1 internal connection) WAN switch.

    Once reconfigured for VLAN1 on ports 0 & 1, for the WAN side you can plug in the cable modem to port 0 and a PC into port 1 (which could request an IP via DHCP from your cable provider). Any packets flying around in VLAN0 will be routed to the appropriate place by the switch.

    This obviously this requires that your provider will allow/allocate 2 different IP's.

    [side note: where nice to allocate 2 IP's for my routers, however stupid enough to allocate them on different net blocks....]

    Get out clause... don't know whether this is possible via the DD-WRT gui, however it looks like you can edit the config files to achieve the same thing.

    Have fun re-purposing your router,
