  • Use an audio/video file from a Linux laptop via USB to be played by Magic Sing ET-23H

    - by AisIceEyes
    I am one of the technical directors of a regular karaoke contest event. For the karaoke contest itself, due to tight budget, we are using what one of the sponsors are providing - Magic Sing ET-23H . The video output of the Magic Sing ET-23H are broadcasted at two big screens that are being shown to the audience and event attendees. When a karaoke contestant provides his / her karaoke video, the video itself is in a readable USB flashdrive and is attached to the USB input of Magic Sing ET-23H. What really bugs me is that the interface of Magic Sing ET-23H are also being broadcasted at the big screen video feeds. The interface of choosing the video file is being seen in the Magic Sing ET-23H - also to the big video screens that are seen by the audience and event goers. I will post in the comments ( if my less than 10 reputation would allow me) the picture of Magic Sing ET-23KH USB input of the device. I always bring my laptop, Acer AS5742-7653, during the regular karaoke event. I'm using my laptop also for tallying of scores from the judges, and also playing audio files from contestants that did not provide a karaoke video. I personally am using different Linux distros, but I next to all the time use my Ubuntu Studio 12.04.3 64bit partition during the regular karaoke contest event. My question is this: Is there a way I can share a temporary video/audio file directly from the laptop I'm using, going to the Magic Sing ET-23H that can broadcast both the video/audio file? Just like how in Window's Avisynth AVS files, or VirtualDub's temporary avi file, or like using ffplay (of ffmpeg), etc. I have researched somewhat the matter and found links in SuperUser.com. Though I can only provide the links at the comments section of this post if my reputation of less than 10 would allow me. I have a hunch it is possible, but I have not fully understood the device being used at the event, Magic Sing ET-23H, if there are other ways for it to broadcast video and audio files besides its USB input. Any help to my current predicament is highly appreciated. Thank you. PS: Since I need at least 10 reputation to post more than 2 links and also post images, I will try to post the image & links at the comments (if my below 10 reputation would allow me).

  • Is it possible to detect Android and iOS devices based on DHCP requests?

    - by abbot
    I want to configure DHCP server in a way that it puts "regular" smartphones and tablets into a separate subnet. Is it possible to detect if the DHCP request comes from an Android or iOS device based on the DHCP request itself? For example: a Sony android phone which was around set the following DHCP options in request, which are potentially useful for identification bootp.option.vendor_class_id == "dhcpcd-5.2.10:Linux-2.6.32.9-perf:armv7l:mogami" bootp.option.hostname == "android-c7d342d011ea6419" Are there any known common patterns in DHCP request options better then MAC prefix?

  • pull bandwidth from wireless WAN into local LAN

    - by cortical
    We have a local network (A) of about 50 computers connected via gigabit ethernet. We get a connection to the internet using two broadband connections to a backbone and distribute the bandwidth across the 50 computers using a CISCO 1811 router, but the bandwidth is not enough for everybody. There is a campus wide wireless network(B) that has very high bandwidth, is there a device or way to setup multiple individual connections to network B and supply the bandwidth to our network A?

  • Group Policy fault - Students force

    - by Richard 'Bean' Williams
    Work at a school and we've got a scenario. We block F8 on all computers so students cannot access Safe Mode to bypass Group Policy... But students are logging into their accounts using AD, and they are turning them off half way through. Then they are claiming that when they login next time, they have Local Administrator accounts. Is this right, but we have blocked F8 and Startup repair, so wondering how they actually did it. Cheers Richard

  • How do I restore my audio after uninstalling Ventrilo?

    - by Marcx
    Hi, I've a Dell studio 1555 bought on september with Windows 7 64bit Professional on it. The audio device works proprerly, while listening to audio contents (from disk or internet) When I use Ventrilo, the audio from other people sounds good and I hear their voices clearly When I use any other VOIP programs like Teamspeak 3, MSN or Skype, I hear a disturbed voice, and it's impossible to comprehend something... Anyway everything worked fine until I installed Ventrilo, but removing it didn´t solve my problem. So how do I restore my audio?

  • Can't find advanced settings on my SMC router

    - by homestead
    Trying to change my SMC router's WAn setting to use opendns dns. Following the instructions: https://store.opendns.com/setup/device/smc I don't see advanced settings anywhere, and none of the menu or menu options have WAN and dns relation options. Could my ISP (who provided the router) blocked that option?

  • Lubuntu LiveCD disabling auto-mount.

    - by PxE Booter
    In cooperation with my IT teacher we want to boot all PC's in IT class with Lubuntu. I've successfully set up PXE server, but there is one thing that worries us. Harddrives shouldn't be accessible from booted Lubuntu(normal user only). Would adding to fstab something like: /dev/sda1 /Idk/What auto noauto work? I'd like to add that I can uncompress squashfs livecd filesystem. If no, what other solution is there, to block auto-mounting /dev/sda drive?

  • How do I remotely enable the firewall on Server 2008 to exclude specific IP addresses?

    - by Guy
    Previously I was working with Server 2003 and managed to lock myself out of the server (I was accessing it remotely) by enabling the firewall. I want to remotely enable the firewall on Server 2008 without locking myself out of the server (access via RDP) and then selectively add IP addresses to the firewall to exclude. i.e. block specific IP addresses. Are there any step by step instructions on how to safely do this?

  • Is there any way to set up a malware-blocking transparent proxy on an Airport Extreme?

    - by Chris R
    I'd like to add some kind of easily-administered transparent HTTP proxy to my home network. Ideally, it would allow me to, for example, redirect web requests to blacklisted servers into nothing, block certain kinds of content, et al. My home network at the moment consists of a mac mini media server that could -- if the load wasn't huge -- fill this role as well, an Airport Extreme, and a mac laptop that is my main machine. I'm reasonably technically savvy, so don't spare the complicated answers.

  • How to take a call without forwarding it

    - by ageis23
    Hi I have a traditional telephony system at home. I also got an voip ATA device connected to the telephone socket. On a normal phone you can just plug it into the wall socket then multiple people on different phones can speak a the same time. Currently for me to take this call whoever answered the call will forward it onto my internal number. Is there not a way I can make it work like the analogue system so I can just pick up the phone?

  • Zenoss: Getting SNMP stats over SSH

    - by normalocity
    I have the SSH connection working. I have it successfully modeling the device (Ubuntu Server, in this case). What I can't get to work is the SNMP portion. It sounds like I have to custom add the snmpwalk command when doing monitoring over SSH - in other words, have Zenoss connect via SSH, and then run an arbitrary command agains the client (in this case, an snmpwalk), and then parse the results. What I need help doing is: Add the snmpwalk command to the SSH monitoring Parsing the output and getting the data back into the charts

  • Windows Server not installing audio drivers properly

    - by user34322
    I am trying to install a dummy sound card on a Windows Server machine (in Amazon EC2 cloud) in order for one of my application to work. I'm trying to accomplish that with Virtual Audio Cable and REAUDIO3. Both tools managed to install a new device on my Windows XP machine, but on Windows Server, no new devices appear. Windows Audio and Plug and Play services are Started and Automatic. ANY ideas are greatly appreciated.

  • Can I simulate human typing on Windows?

    - by James Sulak
    I'm working on a talk that will involve typing code and running it in front of an audience. So I don't screw it up, I'd like to pre-record typing the more complicated bits of the source code and play it back. Most programs I've found that do similar things (like AutoHotKey) dump the text instantaneously as a giant block. Is there any program that will do this and allow me to adjust the play-back speed?

  • Logon onto shared Windows account using individual passwords?

    - by Tom
    In a networked WinXP environment, I have a computer-controlled device which I want to connect to the network, but allow various people to use. The computer must be left running and logged on at all times. My thought is to run the computer under a "shared account" which would allow each user to logon/unlock the screen using their own network password (i.e., the password for their personal account). Is this possible? Thanks, Tom

  • Unreceived SNMP traps

    - by Stephen Murby
    I have 2 CISCO IE3000 and 2 IE3010 switches. They are each configured to send traps to the one host which hosts my NMS [ManageEngine]. The only traps I have enabled on the switches are authentication and linkStatus messages (Up/Down), currently I have my NMS polling with the right community and receiving as ManageEngine checks when adding a managed device, but no linkStatus traps are received. I know they are coming because I have capture them with wireshark, but they are not received by my NMS, any ideas?

  • Copy photos from memory card (How do I manually start the wizard?)

    - by Motti
    I want to copy photos from my camera's memory card using Windows photo copy wizard, however I'm not connecting the camera directly (I lost the cable) rather I'm inserting the camera's SD memory card into the memory card's slot. Windows (Vista) recognizes the memory card and I can explore the photos but it doesn't automatically launch the "Device connected, what do you want to do" wizard. How do I manually launch the photo copy wizard?
