  • Communication btwn active 3d glasses and source(s)?

    - by selfmade.exe
    I know that 3d active shutter glasses work with infared or radio (radio = only bluetooth?). I know that both of them are harmfull but, with either of them, does only one signal get send, to just syncronize glasses with monitor, or the trnasmitter and glasses communicate the whole tiime? An infared/bluetooth transimition for a second(s) is tottaly acceptable, no complain at all, unless the transimition is the whole time.

  • Routing with VPN and asymmetric communication

    - by Louis
    I'm stumbling on a problem that requires your advice. Keywords : networking, route, openVPN Problem : I have a local network with several physical servers and VMs. These machines have ip's in the range 10.10.x.x. I can access these machines from the Internet with the help of openVPN. These machines can : access each other within the local 10.10.x.x subnet access the Internet via the VPN can themselves be accessed (via SSH) from the Internet via the VPN. There is one machine however that behaves strangely and I don't know why. I can SSH into this machine from anywhere via SSH and I can also PING it from anywhere (including the Internet). However from this machine (i.e. when logged into it) I cannot access the Internet or ping machines outside the local network. In other words it will not go beyond the VPN. My question is why? Here are some technical details: The machine's Network Config (running Debian 6.0.3): allow-hotplug eth0 iface eth0 inet static address 10.10.10.200 netmask 255.255.0.0 network 10.10.10.0 broadcast 10.10.10.255 gateway 10.10.10.200 The machine's Routing : Destination Gateway Genmask Flags MSS Window irtt Iface 127.0.0.1 0.0.0.0 255.255.255.255 UH 0 0 0 lo 10.10.0.0 10.10.10.250 255.255.0.0 UG 0 0 0 eth0 10.10.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 0.0.0.0 10.10.10.250 0.0.0.0 UG 0 0 0 eth0 0.0.0.0 10.10.10.200 0.0.0.0 UG 0 0 0 eth0 The VPN's Network Config (running Debian 6.0.3): # This is the local network interface auto eth1 allow-hotplug eth1 iface eth1 inet static address 10.10.10.250 netmask 255.255.0.0 broadcast 10.10.10.255 gateway 10.10.10.250 The VPN's routing table Destination Gateway Genmask Flags MSS Window irtt Iface 10.10.0.0 0.0.0.0 255.255.255.0 U 0 0 0 tun0 private 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.10.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 0.0.0.0 10.10.10.250 0.0.0.0 UG 0 0 0 eth1 0.0.0.0 private 0.0.0.0 UG 0 0 0 eth0 net.ipv4.ip_forward = 1 on both machines. there are no iptables set anywhere.

  • TCP/IP communication between Hyper-V host and guests

    - by Tedd Hansen
    This may be a simple one. :) I have a simple Hyper-V setup with a few guest os running. The host has 1 physical network adapter with a static IP assigned to it. The guests have network adapters assigned to "Internet" (Hyper-V network) which is bound to the physical host network adapter (Hyper-V "External" connection type). I am not able to communicate (ping or anything else) between guests and host. I've checked firewall and it seems fine (ports open from anywhere still don't work). I'm trying to communicate with the hosts IP assigned to the same physical interface that the guests are sharing. Guests can communicate between them just fine. I can't seem to find any relevant setting (I might just be missing it). So my questions: How do I fix it so host and guests can communicate?

  • Logging communication between two VMs

    - by sYnfo
    Hi, I'm trying to set up "malware lab" described in this paper. So far, I've set up Windows guest system, adding one Host-only Network adapter, and setting this (sorry if the names aren't exactely correct, I don't have an english language version): - IP Address - 10.0.0.3 - Subnet mask - 255.255.255.0 - Default gateway - not set - Preferred DNS - 10.0.0.4 - Alternate DNS - not set And a Linux guest system - Ubuntu 9.04 - with two Network adapters - Bridged (eth0) and Host-only (eth1), and setting eth1 IP Address to 10.0.0.4, leaving the eth0 to be set by DHCP. Then, I have configured iptables as described in the paper, ie.: iptables -F -t nat iptables -F -t mangle iptables -t mangle -P PREROUTING ACCEPT iptables -t mangle -P OUTPUT ACCEPT iptables -t nat -P PREROUTING ACCEPT iptables -t nat -P POSTROUTING ACCEPT iptables -t nat -P OUTPUT ACCEPT iptables -t mangle -A PREROUTING -i eth0 -j ACCEPT iptables -t mangle -A PREROUTING -p udp -i eth1 -d 10.0.0.3 --dport 53 -j ACCEPT iptables -t mangle -A PREROUTING -p tcp -i eth1 --dport 80 -j ACCEPT iptables -t mangle -A PREROUTING -p tcp -i eth1 -d 10.0.0.3 --dport 6000:7000 -j ACCEPT iptables -t mangle -A PREROUTING -i eth1 -j ULOG iptables -t mangle -A PREROUTING -i eth1 -j DROP Now, when I try to ping the windows system from within the Linux system, it does not reply, I guess thats perfectly normal, because iptables is blocking ping responce. Same when I try to ping the Linux system from within the Windows. But when I try to access any web page from within the Windows system, I would expect that this action should get logged by iptables. But thing is, I don't see any of that kind of lines in log file (If I am looking in the right place, that is. :) It is at /var/log/messages, isn't it?). So, what do you think might be the problem here? I should note, that this is the first time I'm using linux, so don't expect ANY working knowledge of Linux at all... :) Also, since english is not my mother tongue, feel free to point out any gramatical mistakes... :) Thanks for any advice.

  • Windows 8 Communication Sound Setting not working

    - by blackmastiff
    I've been having a problem on my new laptop recently which is familiar but baffling the usual fixes. I'm running Windows 8 with an onboard Realtek soundcard. It's similar to the one on my older computer running Windows 7. The problem is, when I'm in Skype or Mumble, Windows changes the sound output to lower everything else automatically. I've disabled the communications sound change option on the communications tab within sound devices and checked all the applications settings to insure that they are not responsible. They aren't, and I noticed something else. When I'm in the sound properties dialog, and I switch to the microphone tab, the same audio output reduction occurs. This seems to say to me that the microphone must be responsible in some way, but seeing as I uninstalled all the drivers and installed windows drivers instead, I'm confused as to why this would be occurring. Any thoughts? EDIT: I just tried disabling the built in microphone and the sound no longer get changed. More confused now? As soon as I turn it back on, the sound gets dropped again. Incidentally, the fix for this on windows 7 was this question: Windows 7 lowers applications' volume automatically I've got my computer set that way and it doesn't work.

  • How to generate Serial Keys? [closed]

    - by vincent mathew
    Which software can I use to generate Product keys if I have the GroupId, KeyId, Secret and Hash for the generation? Edit: I had seen a post which generated Product Keys using this information. [Additional Key Details/Activation Decryption*: GroupId = 86f 2159 KeyId = ed46 60742 Secret = e0cdc320ba048 3954789545910344 Hash = 5f 95 ] So I was wondering if there is any software which could generate keys using this information? Thanks.

  • git difftool, open all diff files immediately, not in serial

    - by Seba Illingworth
    The default git diff behavior is to open each diff file in serial (wait for previous file to be closed before opening next file). I'm looking for a way to open all the files at once - in BeyondCompare for example this would open all the files in tabs within the same BC window. This would make it easier to review a complex set of changes; flick back and forwards between the diff files and ignore unimportant files.

  • Update the Progress bar using winforms c#

    - by karthik
    There is a functionality in my module, where the user can scan the number of serial ports in the system and when the user clicks "Auto scan" button, the code will have to go through each serial port and send a test message and wait for the reply. I am using Progress bar control to show process of autoscan. For which i need to pass the value to "x" and "Y" in my code to update the bar. How can i pass the value since my code is already in a foreach loop for getting the serialports. Y = should pass the value of total number of serial ports X = should iterate through each port and pass the value Hope i am clear with req. private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e) { string strAckData = ""; foreach (SerialPort sp in comPortsList) { sp.Open(); string sendData = "Auto scan"; sp.Write(sendData); strAckData += "Connection live on port " + sp.ReadExisting() + "\n"; sp.Close(); double dIndex = (double)x; **//How to pass the value here ?** double dTotal = (double)y; **//How to pass the value here ?** double dProgressPercentage = (dIndex / dTotal); int iProgressPercentage = (int)(dProgressPercentage * 100); // update the progress bar backgroundWorker1.ReportProgress(iProgressPercentage); } richTextBox1.Invoke(new MethodInvoker(delegate { richTextBox1.Text = strAckData; })); } private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e) { ProgressBar.Value = e.ProgressPercentage; } private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { StatusLabel.Text = "Auto Scan completed"; }

  • Android 3.1+ USB as virtual COM port

    - by ZachMc
    I have a third party usb device, that when plugged into a Windows machine, is recognized as a serial device and assigned to the COM 4 port. I can communicate with the device just like I would with a device connected via a serial port. For instance, I can write "abc" serially to the device via the USB connection. I have been searching for a way to do a similar thing in Android. If I try the Usb Host method, and use a UsbManager to open the UsbDevice, I can get one interface, with 2 endpoints. I have tried sending control messages using the method in UsbDeviceConnection, but the method returns -1 for everything (though I don't know what I should use for the parameters of that method). Is there a way to get an OutputStream that I can write to that will send bytes to the USB device? Right now I am looking at recompiling the kernel to include a virtual COM port driver and write some native code to be able to do this. Thanks! Edit: I am using the FTDI serial to USB converter circuit. Is this compatible with Android?

  • How do I Connect a 30yr-old Tandy 1400LT laptop to the internet?

    - by Clemens Bergmann
    Just for the fun of it, I want to get an old Tandy 1400LT laptop: small monochrome display two floppy drives rs-232c connector "printer" connector connect the thing the internet and use it as an ssh terminal. How would I connect it to the internet? The software should be no problem as it is a 386 hardware. There should be a small linux distribution which can be run on it. But how would I phisically connect the hardware? It has no ethernet port. Has someone experience with Serial/Paralel-to-ethernet converters?

  • Can't communicate using PuTTY, but can with Termite

    - by SharpHawk
    I'm trying to establish a serial connection to a peripheral from my PC's RS-232 port. Pretty simple stuff, and I've had not trouble doing it with countless peripherals before. And yet when I configure PuTTY to the right baud rate, stop bits, etc. I'll type in "*IDN?", press enter, and the unit won't reply. After going over my settings over and over again, I decided to try another terminal program, Termite. This time it worked like a charm. What puzzles me, and what I'm trying to figure out by posting this question, is why Termite would work when PuTTY did not despite the fact that they both have the same settings. PuTTY: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html Termite: http://www.compuphase.com/software_termite.htm EDIT: I now tried Tera Term as well, and it works. So PuTTY is the odd one out.

  • Is there a way to identify the device data is being received from? (python)

    - by Ed Prince
    Summary I have an MT4000 device connected to my computer using the serial port ttyS0. This is broadcasting data which is being received and read by a udp listener written in Python. I am also sending data manually through the terminal using a bash script I wrote. The Goal Is it possible to identify the device being used? The aim is for a web-page to allow the user to select which device they wish to see the data being sent. I would rather achieve this by directly identifying the device rather than saying anything from ttyS0, in case a different device is plugged in on that port. The Answer Is this possible, and if so, how? Everything I have found so far, is on identifying through a specific port.

  • How can I accurately determine the age of a hard drive?

    - by Todd Stout
    Yes, if it's large, heavy, and only 65 Meg in capacity, you can assume it's ancient. An RLL controller would positively indicate the drive is from antiquity. What about drives that are only 3 or 4 years old? If I know the serial number, make and model is there a public database that indicates a manufacturing date? Update: As trite as this question might seem to some, the hard drive I was looking at that precipitated this question had no obvious manufacturing date stamped on it. I realize that most do. I think the answers given are very useful to myself and others.

  • Text on Cisco ASA console is garbled/missing letters

    - by Some Linux Nerd
    I've actually looked up a number of solutions for this problem and none of them work. There's this Cisco ASA 5505 that I'd like to use, that outputs mildly garbled text with missing characters. I did some googling and found that the most likely problem is a bad baud rate, so I tried all the baud rates, 7N1, 8N2... basically every possibility minicom had. Then I figured (since I can type ok, just not read) that if I factory reset it that it would fix whatever is set wrong with the terminal. That didn't work either. This usb-db9 adapter and console cable work fine on the catalyst switch in our office. My serial settings are 9600 8N1 with no flow control. Anyone know how to fix this? I have an example of the text on pastebin: http://pastebin.com/MAJF0mVU - it's just lots of "Dfaut cnfiuraionfil cotais 1enty." instead of "Default configuration blah blah"

  • How do I find the Serial Number of a USB Drive?

    - by jamuraa
    I'm trying to re-enable USB Autoplay in a secure way, by installing a program on each of the computers that I use so that I can run my launcher (PStart in this case) whenever I plug in my specific USB drive. The tool that I'm using to enable this - AutoRunGuard - needs the serial number of the USB drive that I am using. I can't figure out where to find this in Windows. Ideally I would not need to install and run a separate program to do this (seemingly) simple task. Since this is a pretty easy question, bonus points if you also tell me how to discover it in Linux as well. What steps do I need to take to retrieve a USB Drive's serial number? UPDATE: Just incase people come here looking for the answer for AutoRunGuard, I discovered that they don't want the USB device serial number, but the volume serial number. The drive serial can be found by going into the command line, navigating to the drive, and executing dir. The volume serial number is found in the top two lines - use it without the dash.

  • How to communicate between Client and Server in a Client-Server Application?

    - by Sanoj
    I would like to implement an Client-Server Application, where the business-logic, security validations and a database are at the server and the user interface are at the client. I would like to implement clients in different languages i.e. one in WPF/.NET, one Swing/Java , one in Android/Java and maybe one HTML/JavaScript client. The server will be on Internet, so I would like to be able to have encrypted communication. The client will send some lists of items to be added to the database, or update items, and do some transactions. The server will check if the items are already updated by another client, or update the item, add new items or delete items. How do I solve the communication between clients and the server in such a system? I have been thinking about: http/https webserver, and sending messages in JSON or XML and use Web Sockets for bi-directional communication. Use http in a RESTful way, except when WebSockets are needed. But I guess there are better solutions for native desktop applications than http? CORBA - I have just heard about it, and it's old and complex. Not much talk about it these days. XMPP/Jabber - I have just heard about it and I don't know if it fits me at all. EJabberd seams to be a popular implementation. AMQP - I have just heard about it and I don't know if it fits me at all. RabbitMQ seams to be a popular implementation. Windows Communication Foundation, Java RMI, Java Message Service - but are they language independent? I guess some of these alternatives are on different levels, maybe I can have i.e xmpp or amqp in web sockets over https? What technologys are used for this problem in companies today? and what is recommended to use? I have no experience of them other than webservers and http. Please give me some guidance in this jungle. What are the pros and cons of these technologies in my situation?
