  • Technology mash: is this possible?

    - by Jon Story
    I'm in the process of setting up my own DNS+hosting on a couple of VPS and my home machines, mostly for academic/learning purposes, but also for convenient accessing of my files, hosting my personal websites, private git repositories etc. I've got a main web server with DNS, and a slave DNS server. I've also got a couple of machines at home doing file hosting, video streaming and all that fun stuff. I'm intending to use my VPS's to provide myself with a dynamic DNS system so that I can point mydomain.com at my DNS servers, with home.mydomain.com going into my home network via a raspberry pi. HOWEVER.... I've not got access to the network infrastructure at home (rented accommodation with managed internet), so I can't forward the ports on the router to my own machines. As such, I'm wondering if it's possible to route all the traffic via an SSH/HTTP tunnel through one of the VPS? My plan is to have the raspberry pi provide a VPN into my home network. The raspberry pi uses SSH to connect to the VPS, and the VPS forwards any traffic to home.mydomain.com via the tunnel to the raspberry pi. Is this even possible, and how do I go about it? I don't mind getting my hands dirty with coding and low level tools, I'm just not sure where to start or what the best way to go about it is.

  • How to determine the root cause of a system lockup on Ubuntu 8.04 LTS?

    - by jdt141
    I'm currently working a project that involves setting up a PC/104 stack and running Ubuntu 8.04 LTS. We need to use the PC/104 stack because its an embedded application - and we're required to use a DeviceNet peripheral card to communicate to other devices. (DeviceNet is just a protocol on top of CAN.) Anyway, the following hardware is on the stack: Kontron MOPSPM104 with a 1GHz Intel Celeron processor ConnectTech FlashDrive/104 4GB Industrial Temp (-40 to +85 C) Woodhead (Molex) PC104DVNIO DeviceNet card A run of the mill 104 power supply The Kontron Board offers two serial ports, one VGA out, and two USB ports. The DeviceNet card is an ISA card. Because of this (per the User's Guide for the Kontron Board), I have manually set the IRQs in the BIOS to be appropriately configured, and turned off ACPI in both the BIOS and passed the appropriate flag in GRUB. I've installed Ubuntu 8.04 desktop, 32 bit. The problem that I'm having is that, from time to time, the entire 104 stack locks up. This only seems to happen in two cases, both of which we're running GNOME. We have a custom application that uses the DeviceNet card, and the system will lock up, or (more frequently) when we're running Firefox and either surfing for some information or trying to test it - typically by streaming video from a IP-camera. The reason I ask this questions is I cannot determine the root cause of this lockup. The IRQs appear to correctly configured in the BIOS and as the Kernel sees them, and nothing is logged to dmesg. If you all could help me determine the root cause of this lockup, I would greatly appreciate it. Thanks.

  • FreeNAS pool configuration - RAID1 + other drives

    - by trnelson
    Simple questions, really. I found this answer with a similar setup, but not sure it answers my question. If it does, I'm curious why since the answer seems a bit unsure: ZFS Hard Drive Configuration in FreeNAS I'm building a server which will be used primarily for backup, plus some media streaming, possibly with Plex. I seem to understand most everything I need, but I'm still a bit confused on how pools work, and how to configure them for my scenario. I will have 2x 2TB WD Red drives, which I plan on using in a mirrored set up (RAID1). This would be for backup, and I'd also like to do offsite backup to my CrashPlan account from this array. I also have a few other drives: 1.5TB, 320GB, 250GB. I'm not sure exactly what to do with them yet, but looking for options. FreeNAS OS will be running from a 16GB USB Flash drive. Would it be wise to use the 1.5TB as a backup-backup, essentially as a mirror or perhaps for snapshots of the 2TB RAID1? I'm still learning about snapshots. Should the 2TB mirrored drives be in their own pool? Should the other drives be set up in their own pools as well, or should they be JBOD in a single pool? They may or may not get much use since the 2TB array is plenty for me. Does a dataset basically mimic the idea of a partition or a network share? In other words, I would map \SERVER\Share to X: on my laptop? Let's say I wanted to use the 250GB drive as an encrypted drive to store all of my cat pictures. Would it have to be in its own pool? If I use jails apps, should they go in the backup RAID1, or in another place? Thank you!

  • unable to capture picture using camera in j2me polish?

    - by SIVAKUMAR.J
    I'm, developing a mobile app in j2me.Now im converting it into j2me polish. In my app I capture a picture using camera in mobile phone. It works fine in j2me. But it does not work fine in j2me polish. I cannot resolve it. The code snippet given below public class VideoCanvas extends Canvas { // private VideoMIDlet midlet; // Form frm Form frm=null; public VideoCanvas(VideoControl videoControl) { int width = getWidth(); int height = getHeight(); // this.midlet = midlet; //videoControl.initDisplayMode(VideoControl.USE_DIRECT_VIDEO, this); //Canvas canvas = StyleSheet.currentScreen; //canvas = MasterCanvas.instance; videoControl.initDisplayMode( VideoControl.USE_DIRECT_VIDEO,this); try { videoControl.setDisplayLocation(2, 2); videoControl.setDisplaySize(width - 4, height - 4); } catch (MediaException me) {} videoControl.setVisible(true); } public VideoCanvas(VideoControl videoControl,Form ff) { frm=ff; int width = getWidth(); int height = getHeight(); // this.midlet = midlet; Ticker ticker=new Ticker("B4 video controll init"); frm.setTicker(ticker); //Canvas canvas = StyleSheet.currentScreen; videoControl.initDisplayMode(VideoControl.USE_DIRECT_VIDEO,this); ticker=new Ticker("after video controll init"); frm.setTicker(ticker); try { videoControl.setDisplayLocation(2, 2); videoControl.setDisplaySize(width - 4, height - 4); } catch (MediaException me) {} videoControl.setVisible(true); ticker=new Ticker("Device not supported"); frm.setTicker(ticker); } public void paint(Graphics g) { int width = getWidth(); int height = getHeight(); g.setColor(0x00ff00); g.drawRect(0, 0, width - 1, height - 1); g.drawRect(1, 1, width - 3, height - 3); } } In normal j2me the above code works correctly. But in j2me polish videoControl.initDisplayMode(VideoControl.USE_DIRECT_VIDEO,this) here this refers to VideoCanvas (which extends from javax.microedition.lcdui.Canvas). But it throws an "IllegalArgumentException - container should be canvas" like that. How to solve the issue?

  • UIVideoAtPathIsCompatibleWithSavedPhotosAlbum generates error implicit declaration of function, why?

    - by just_another_coder
    In my project I am trying to save video to the iPhone after being taken by the camera. When I call the method: UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(path) It reports the error: Implicit declaration of function 'UIVideoAtPathIsCompatibleWithSavedPhotosAlbum' I've imported MobileCoreServices/UTCoreTypes.h I was previously using this same code for saving camera pictures, and it worked fine. In another class, in the same project, I am able to reference the UIKit method: UIImagePNGRepresentation() without any problems So why does it give me this error?

  • How can I access windows file preview icons from my WPF application

    - by Jobi Joy
    I got a bunch of Pictures and Videos in a directory and needs to be displayed in the WPF application, I am thinking about displaying the Win7 Large Icon itself as the preview image. Because that will save me the work of grabbing an appropriate frame from the video file since Windows is doing that job pretty well already. Any code snippet to access this Shell Icon image data?

  • Are there any GOOD Chef, Chef-Server and Chef-Client tutorials out there?

    - by btelles
    Hi there, Chef from Opscode seems to be really useful for configuring servers and such, but trying to follow their documentation is a little difficult. Some terms are defined after they are used, and definitions sometimes reference new terms that you haven't yet encountered. Anyone know of any GOOD tutorials/walk-throughs for getting a good understanding of Chef, Chef-Server and Chef-Client? I remember seeing one video presentation online, but it barely scratched the surface.

I was wondering if I have to create a new field Image - File Upload for the second group, or I can somehow to re-use the first one (which is already added, and I would like to add it twice in the second group as well). thanks

  • How to debug c++ DirectShow filter

    - by Mr Bell
    What debugging tools are available for directshow filters? Presently, I have a project that compiles and registers a video source filter that I then setup a graph in GraphEdit. I am using c++ in visual studio 2008. Is it possible to get a debugger attached to the filter in any way where I could set break points, inspect variables, etc? Barring that is there a way to log diagnostic information somewhere that I can view in real time?

  • Performance experiences for running Windows 7 on a Thin-Client?

    - by Peter Bernier
    Has anyone else tried installing Windows 7 on thin-client hardware? I'd be very interested to hear about other people's experiences and what sort of hardware tweaks they had to do to get it to work. (Yes, I realize this is completely unsupported.. half the fun of playing with machines and beta/RC versions is trying out unsupported scenarios. :) ) I managed to get Windows 7 installed on a modified Wyse 9450 Thin-Client and while the performance isn't great, it is usable, particularly as an RDP workstation. Before installing 7, I added another 256Mb of ram (512 total), a 60G laptop hard-drive and a PCI videocard to the 9450 (this was in order to increase the supported screen resolution). I basically did this in order to see whether or not it was possible to get 7 installed on such minimal hardware, and see what the performance would be. For a 550Mhz processor, I was reasonably impressed. I've been using the machine for RDP for the last couple of days and it actually seems slightly snappier than the default Windows XP embedded install (although this is more likely the result of the extra hardware). I'll be running some more tests later on as I'm curious to see particularl whether the streaming video performance will improve. I'd love to hear about anyone's experiences getting 7 to work on extremely low-powered hardware. Particularly any sort of tweaks that you've discovered in order to increase performance..

  • Why are SIP calls via my server silent?

    - by Archcode
    I have FreeSWITCH SIP server up and running. It has public IP and sits behind 1-to-1 NAT (it's Amazon EC2 instance actually). I can connect to it, make a call to other endpoint (namely, my android device to my pc and vice versa) and signals are send with no problems (call, answer, hangup, etc). Unfortunately, and what drives me crazy, that's all: no audio gets through, no video either. Server does not throw errors, it reports many retransmission though, looks like this: switch_rtp.c:915 [ zrtp engine]: WARNING! HELLO Max retransmissions count reached (20 retries). ID=15 Codecs are set up correctly (same config worked locally on my LAN). NAT/firewall on client side may be a problem, signals do get through (perhaps due to fixed port, data streaming runs on random one, that is currently my best bet). STUN/TURN/ICE setting on client seem to have no effect. Endpoints sit behind symmetric NAT. On server there are no iptables rules, security group is set as suggested there: http://wiki.freeswitch.org/wiki/Firewall Help, please. How to make it work or at least diagnose what's wrong?
