[beagleboard] BBB as VPN relay server
Hello Beagleboners! So I have at home the Amaon Fire TV box and one of the problems is that I would like to use it with VPN in place to avoid some geo restrictions. As far as my googling goes you cannot do this directly on the fire TV box My thought is using a beaglebone in between to provide a VPN. So the setup would be: Amazon fire TV -> lan -> Beaglebone Black -> via VPN into the internet Is something like this possible? I could imagine adding some buttons or something so that you can chose easily if you want to have the VPN on and if so to which country you want to go. Any pointers would be appreciated!

[beagleboard] Re: Internal error messages
Ooops it did it again..*trallalla* Just got exactly the same error again. only the numbers in the brackets [] are different, but I suspect this is system time or something. So I guess there is nothing I can do? Bought the beaglebone in summer, and have been playing with it since. For most of the time it has been lying on my desk without case or so, therefore I guess heat should not be an issue (also at nights it gets well below 20 C indoors these times!)

Yeah, that's an interesting one and immediately got my attention because there two kernel errors in your listing and no other indications. Both are thrown by the Power Reset Module (PRM) IRQ located at 44e0b000 on the L4_WKUP bus. 1) Error 1028 - I have no idea what it is but my guess is there's a bit mask 1024 | 4 somewhere that explains it. 2) Oops 17 - This is an MMU page fault error indicating (again a big guess!) there is something wrong reading/writing a memory page. I suspect a momentary blip (heat or EMI related maybe) that caused an L4_WKUP bus hiccup. OR, if you have been using this BBB for a long time the eMMC flash might be getting to end-of-life (which is accelerated in a hot environment.) If that is the case, you will see more and more MMU faults. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] USB mini male cable (both sides mini)
Hey, I am using the BBB for backup and therefore I need two UBS connections. One for my Wifi and the other for my external HDD. As the BBB has two USB Ports I would like NOT use an USB hub. The HDD also has a USB mini connector, so I would like to connect from USB mini on the BBB to USB mini on the HDD. That means I need a cable with USB mini male on both sides. Is there such a thing? Anyone knows a place where to buy one? I searched for quite a bit, but could not find one. I also tried one of those USB mini to USB A http://www.amazon.com/dp/B004I0FK6M/ref=pe_385040_127541860_TE_3p_dp_1 adapters and then use a normal USB cable. But it seems the adaptor does not work... Any ideas? I am also thinking of cutting two cables and to make my own...

Re: [beagleboard] USB mini male cable (both sides mini)
Well the slave usb port is hard wired for slave only, so you'd also have to physically modify the board.. That is annoying. That means basically that I am stuck with an USB hub?! PS: I really think having a couple of USB Ports should be on such a board. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] make BBB Debian Hackerproof
Thanks for your suggestions. I will look more into it. I am aware that full security is not achievable, I wanted more to make sure that there is no super easy way in where everyone could just see whatever they want to. Also that was my point about removing/disabling unused features. Then I do not need to keep them up to date when they are not present any more. Thanks!

Unless you physcally modify the board with a gallon of hard epoxy and seal it in concrete. ;) The board was designed for ease of development... By the default, the bb.org image has root access open (no password) and ssh on port 22.. There's a script under: /opt/scripts/un-tweak-image/debian-re-secure-root-ssh.sh That'll reset root to a password (root) and disable root over ssh. Next disable bone101/cloud9 both applications give you root access to. ;) BTW, for this project, starting with something really bare bones such as: https://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-Debian7(smallflash) Regards, -- Robert Nelson http://www.rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: Wifi unreliable
thanks for your replies. I just ordered a different USB plug, let's see if that improves things. After tinkering so much with it, it seems the better options. In the end it is probably cheaper spending another $14, rather than sitting hours of hours trying to fix it. Hope the TP-LINK TL-WN722N http://www.amazon.com/gp/product/B002SZEOLG/ref=oh_aui_detailpage_o00_s00?ie=UTF8psc=1 will help. I'll also try to also do what you suggest Dave, let's see if that helps too.

[beagleboard] Wifi unreliable
Hey everyone, I have been using the BBB now for quite a while and I really like it. There is only one persistent problem I do not seem to get rid of. So I hope you can guide me into the right direction. I am using the Ourlink wifi dongle https://www.adafruit.com/products/1012 to connect to the internet and wicd-curses to set up the wifi. Initially it seems to work fine. However, quite often the dongle disconnects and I am no longer connected to the internet. I am unsure how to proceed or what I could try. A couple of observations/comments: - I am using an external usb hub http://www.amazon.com/dp/B005A0B3FG/ref=pe_385040_121528360_TE_dp_1 and the beaglebone is also powered from a 5V wall plug https://www.adafruit.com/products/276. So sketchy power supply should not be the issue as some people indicate. - Interestingly wicd-curses still indicates that it is connected, however the router does not confirm that and I cannot connect to the BBB. - It seems to happen more often when I try to run BTSync to push a lot of data through the BBB to an external HDD. If it sits just there and idles it can be online for days without problem. Do you guys have any advice what to try? I am quite lost and the internet does not give me any more help... Thanks!
