  • How to use 2 or more internet connections on the same network?

    - by Rogue
    Living in a joint family we have 3 internet connections, each floor has one internet connection which is split per floor. Each internet connection is shared between 4-5 computers using a switch per floor. Each of these internet sharing networks are independent of each other. What I want to achieve here is a local network (for local messenger and file sharing) that can combine all the 3 independent networks, problem is that whenever I try to do that the whole network tends to use just one internet connection. I have all the necessary hardware. How do I solve this problem, one approach could be that I could get one PC to act as a server and bridge the internet connections and then the whole network would have to access the internet through this server. Theoretically this could be possible but I have never tried this approach in real life. Also if certain computers need be restricted from internet access how would this be possible on the same network?

  • Using Windows 7 XP Mode for games

    - by Josefvz
    Hi all. I have Win 7 (x64) at home and I want to play some old games (specifically Lands of Lore 3, but also some others). This game does not work properly on Win 7, and there are no patches that I'm aware of to fix its issues. Can I use XP Mode to play this game (and other non Win 7 nice games), or is there a better way? I only have one PC and dual booting scares me... (so no to dual booting!) Another question: Will I have full hardware support (full use of my graphics card, etc) when I use DOSbox or a VM? I have decided to go with VirtualBox or vmware, I'll check which one gives the best performance, thanks for your input!

  • Can I use the voice & SMS features of my GSM SIM through my laptop?

    - by i..
    My laptop (a Lenovo T410s) has an internal GSM modem (device manager calls it a Qualcomm Gobi 2000 HS-USB Modem 9205) that I'm currently using a regular (voice, data, text, etc) 3G SIM in. The data functionality works great through the Lenovo software & Windows 7 but I was wondering if I can use the other features (specifically voice & SMS) through Windows. Is it posisble to use the non-data features of my 3G SIM through my Qualcomm GSM modem? If so, what software is available to this end? If not, where is the restriction? (e.g. hardware, OS, driver, software) Thanks!

  • What is a preferred method for automatically configuring and setting up an Ubuntu instance?

    - by sutch
    I am tired of manually configuring instances of Ubuntu for testing web applications and for setting up workstations. I'm even more frustrated by the issues caused by inconsistent configurations. Is there a method (hopefully not too time consuming to learn and setup) that allows for automation of the setup and configuration of an Ubuntu server or workstation from an ISO. This is primarily for virtual machine instances, but it would be helpful to also create instances on hardware. I am specifically looking for a method to automate the installation of libraries (apt-get), configure services (such as Apache and MySQL), add 3rd party software (download, extract and build), and add libraries to scripting languages (for example, Ruby Gems or CPAN packages for Perl).

  • Solaris x86: Non working keys on keyboard (<, >, #, |)

    - by Thomas
    Hello everyone, I have a new installation of Solaris 10 10/09 on x86 hardware. The attached keyboard has a normal German layout. The system is configured accordingly by 'kbd -s'. The generic keys (letter, number, umlaut) work fine. Unfortunately some keys like <, , | or # do not. They produce no output on the text console at all. I tried PS/2 and USB keyboards. I cannot test it under X11 as it is currently not working. Thanks.

  • Remote access to BIOS?

    - by j-g-faustus
    I have a home server running headless (i.e. without a monitor), using ssh for remote access. This works fine most of the time, but I still need a graphics card and still need to drag out a monitor whenever I have to access BIOS, (re-)install the OS and similar. I know that there are business servers that let you control everything remotely (over Ethernet), including power up and BIOS access. Is this type of functionality available for "prosumer" class hardware? If so, where does it sit - should I look for motherboard support, a PCI-e card or an external device? And does this type of functionality have a name, so I know what to google for?

  • Strange Intermittent Background Sound in Windows 7

    - by NoCarrier
    Ok, this is very strange. Recently, i noticed that every 10-15 seconds, there would be this faint, annoying duh-dum sound coming out of my speakers. (hard to describe. sounds somewhat like the sound windows makes when you unplug a USB device, but not as pronounced and much quieter). I closed every app and ended as many processes as I could, but the sound persists. I look at the volume mixer and sure enough, when the sound occurs, there is a little spike in the level under "System Sounds". I haven't installed any hardware or software in the last several weeks. This started recently - completely out of the blue. Does anyone have any insight?

  • What has changed to make it possible to develop USB3.0

    - by RoboShop
    Like I know the transfer speeds are vastly different. But I don't understand is why they are faster. And why couldn't they have implemented USB 3.0 when they released 1.0? Like what technical breakthrough was required to get transfer speeds that fast? Was it cost? capacities of computer? like they couldn't read the data fast enough? Although USB is still well below hard drive transfer speeds engineering breakthrough? They found some new material which could transfer at a faster rate? Was this in the cable itself? In the hardware?

  • Rename Devices in Device Manager

    - by Luke
    This is mostly just for the USB ports, as I recognize everything else in computers.... Anyways, is there a way to rename, or otherwise, identify which USB port (or other hardware for that matter) is which device in Device Manager? I know I can plug in a flash drive, then see what port it is connected with, and find out that way. What I would like though, is to find out that a certain plug is always a certain device in Device Manager. If I can then have a system in mind that always has the same order, I can look and see if a USB port is not being detected or not working properly, and as I uninstall/reinstall USB devices, I know I won't lose my keyboard or mouse, for example. The OS in question currently is Windows 7, but I would accept a solution for ANY version of Windows USB Devices | +--+USB Root Hub Port A | | | ---Keyboard | +--+USB Root Hub Port B | | | ---Mouse | +--+USB Root Hub Port C | ---Empty

  • Adjusting color on one monitor in Nvidia Surround

    - by Chris Stauffer
    I'm currently running three 2560x1440 screens using Nvidia Surround. Two monitors are Yamakasi Catleaps (cheap Korean jobs) and the third is the Achievia Shimian (also Korean). The Catleaps have great color reproduction, however the Shimian is exceptionally blue tinted. With normal monitors the required correction would require minimal effort to accomplish. But these Korean monitors do not have hardware controls to do it. For those who are unfamiliar, Nvidia Surround basically takes all three monitors and makes one big "monitor" out of all of them (Xinerama for GNU/Linux folk), at a resolution of 7680x1440 in my situation. Therefore, adjusting the color profile in the Nvidia control panel changes the settings for ALL of the monitors simultaneously. Thus, I am looking for some software to adjust the Shimian (perhaps by just selecting the pixels that that monitor encompasses). Does anyone know of such a program?

  • Macbook Pro (SantaRosa) internal display not detected by graphics card, external monitor OK

    - by BLAU
    My MacBook Pro (2.4 Ghz, Santa Rosa with infamous nVidia card) acts strange. It shows the normal gray screen with Apple logo and animation flawlessly during start up but the internal display goes black without any rendering at all when all is loaded. (shining a light on display show nothing) If an external monitor is connected through the DVI port it will remain black during start up and then show the desktop as the internal display goes black. This happens both while booting to Mountain Lion and Windows XP. I have checked "About my Mac" and only the external display is listed. The same is the case if I use the nVidia Control panel in Windows XP. My questions: Is this a hardware problem or is it related to software maybe even firmware? What controls the display during start up, graphics card or something else?

  • Bound external Cisco CIGESM ports to a specific BladeServer

    - by Vinícius Ferrão
    We have an IBM BladeCenter with 14 blade servers and one external Cisco CIGESM for Ethernet connectivity. Since this hardware is a little old, we will use it for other services, and we want to run a pfSense instance on one of the blades. It's just an Firewall Appliance, but it needs two network interfaces: one for the WAN and the other one for LAN access. Our architecture works on top of static routes, we don't use NAT, so we got the WAN IP in one interface routing to the another one. The main problem is how to plug the WAN cable in one of the four external ports and make it exclusive to the blade server containing the firewall. And we also need an exit port that goes through a 3COM 4200G switch that makes the internal routing and VLAN separation. Thanks in advance

  • Setting up Raid 1 Array for Home Server

    - by user1048116
    I'm not sure if this is even possible, but it's worth asking on here! Essentially I have a old machine at home (well, not old hardware wise, but I recently built a new gaming rig), which I decided to install a copy of W2008 R2 on and use as a file/backup server and media center'ish machine. As of now, it has a single drive partitioned into C and D, with D being the Data partition. I have happened to find an old 1TB SATA drive lying around at home, and was wondering if it's possible to setup a Raid 1 array in my rig within Windows without needing to lose everything on my first drive (or maybe even just mirror a specific partition, say the Data partition, as this is just what stores my photos etc). Maybe this isn't possible, but you never know :) Regards, T.C

  • Is there a free tool/package that can monitor web traffic and display URLS accessed? [closed]

    - by Anthony
    I couldn't find a similar question but then maybe I am searching for the wrong terms. A few years ago I used a router like device, I'm pretty sure it was a SonicWall, that did this on a clients site. Basically all traffic would be routed through this device and it allowed the manager/administrator to inspect web usage of the workers, determine how often certain resources were accessed and block them if necessary (much like content filter). It showed reports based on domain name reached etc. Facebbok.com, Bebo.com and so on. It also displayed the usual IP traffic information etc. it was a UTM also. I have tried Endian firewall, with it's NTOP install, but I don't think that will show URLs browsed. Maybe I just haven't found it in NTOP yet? I need this to troubleshoot connection and traffic issue at my home, with about twenty devices/users so didn't want to buy a dedicated solution and have spare hardware to use a community product.

  • Converting a DWG/DXF to CSV or Excel

    - by Menno Gouw
    I'm using ZWcad and i need to get the coordinates of hundreds of blocks into a excel sheet or .CSV file so i can import that into the GPS hardware. I know there are plenty of tools for autocad, i probably can even write one myself but as far as ZWcad goes i seem to be out of options. However ZWcad saves to DWG too, and exports to all the other familiar cad extensions. So i was wondering if i would just save the blocks i need to export to a certain file there might be a tool/program to convert that directly into .CSV.

  • Flash stream makes my internet slow and cpu rush

    - by user1225840
    When I try to watch a live Flash stream, my CPU usage goes up to 75% and my Internet speed goes down. If I run a test before the video-stream, my speed is ~40/10Mbps and during the stream it drops to 0.1-0.5Mbps. The stream is laggy and I can only watch one to two seconds at a time, start/stop/start/stop. I have cleared my history, cache, cookies, temp files, and so on. I have searched for malware and took care of that. I have updated my drivers, reinstalled Flash and everything else I can think of, but it remains slow. I had this problem before and it just started working normally from one day to another. Could it be a hardware problem?

  • Camtasia on remote computer?

    - by daughtkom
    I have a need to use one laptop for a live presentation (with projector, etc.), but record that presentation on another laptop -- similar to what I can do with Camtasia, only with the recording happening on another laptop. Is this possible? What do I need to do this? Some VGA device that goes between the presenting machine and the projector? Some USB device? My ideal requirements: The machines must be "standard" laptops (so I can't just add a new card to a desktop, etc.). I prefer a hardware solution, but cannot involve studio type equipment. I'd prefer not to install Camtasia (or similar) on the presenting machine for two reasons: licensing issues performance issues (sometimes the presentations are machine intensive and I don't want the recording software to interfere with the presentation) I'd appreciate any tips. Thanks.

  • Q: MySQL Cluster - Data insertion in NDBCLUSTER table - error out after 5 million rows

  • Raid recovery in gigabyte GA-8I945 Pro

    - by epeleg
    This was a working machine until a few days ago. And now it won't boot into the OS, during startup if makes clicking sounds (I think from one of the drives). Installed OS: Windows 2003 Web edition Hardware: Gigabyte GA-8I945P Pro , 2*160G Sata in RAID1 configuration , 2 Volumes – 25G and the rest. When I installed windows on it, during setup, I pressed F6 and used ICH7DH drivers of RAID. The manual for the MOBO says: Step 1: After the POST memory test begins and before the operating system boot begins, look for a message which says "Press to enter Configuration utility" (Figure 4). Press CTRL+ I to enter the RAID BIOS setup utility. But the machine never shows this message. BIOS SATA RAID/AHCI Mode is set to RAID. Any ideas or pointers on what I can do to recover my data? Thanks

  • Where can I configure wireless to be passed on to the Virtualbox guest?

    - by huahsin68
    I have WinXP install in virtualbox which host in Linux. I have a TP-Link (TP-WN321G) USB wifi adapter and have the driver installed inside WinXP. When I plug-in the wifi adapter, there is an option show "Ralink 802.11g WLAN [0101]" in the virtualbox's USB icon, tick on that option, the Device Manager able to detect the hardware which shows TP-Link, but when look into the properties, it says there is no driver was install. I did try to install Ralink driver but still no luck. Just curious why my wifi adapter is TP-Link, but the option show Ralink? May I know how can I emulate the wireless network inside WindowsXP?

  • How would you measure the amount of atmospheric dust in a server room?

    - by Tom O'Connor
    We've been advised by our tape library vendor that one of the reasons we might be seeing lots of errors is if our server room is particularly dusty. It doesn't look dusty, but that's not to say it's not there. We've got an environment sensor cluster which measures Temperature, Airflow and Relative Humidity. I should probably point out that the low-hanging fruit solution I came up with is to use Sellotape (scotch tape) in a loop, one side stuck to the server cabinet, the other side free-hanging. I've also put a couple of other tape loops by the exit and intake fans of the hardware (not blocking airflow, naturally). How can we (electronically, ideally) measure dust levels?

  • How do I force a specific MTU for only certain TCP ports?

    - by Dave S.
    Background I have a set of embedded hardware deployed in the field. These remote machines connect back to my servers at AWS running Ubuntu and I use the iptables mangle chain to lower the MTU to 500 so these devices are happy. For reference, this is the iptables rule I am using: -A POSTROUTING -p tcp --sport 12345 --tcp-flags SYN,RST SYN -o eth0 -j TCPMSS --set-mss 500 Current Problem I'm trying to spin up some servers on the Joyent Cloud using SmartOS, but I can't find any information on selectively changing the MTU like I can on Linux (e.g. all info I've found is on changing it globally, which is not what I want). How would I do it so that all connections on TCP port 12345 get the MTU I want?

  • How do I swap audio output of the left and right speakers?

    - by Manga Lee
    I have two speakers stereo speakers but when I use the sound control panel applet to test my audio configuration I get sound in the right speaker when the user interface indicates the right speaker and vice versa. Is there a way to swap the audio output from left to right and right to left? UPDATE: The reason for this question is that I've recently rearranged my workspace and because of physical constraints the left speaker has to go on the right side and vice versa. I could of course solve this problem with a hardware solution but I'd rather use a software solution if one is available.

  • Cable installed - now my hub has no connection the router/modem - what do I need to buy?

    - by bcmcfc
    My previous setup was as follows: [modem/router]------[switch]+------ [pc1] +------ [pc2] I've just moved and had cable installed and I no longer have the option of running a lengthy LAN cable from the router to the switch to provide network and internet access to the two PCs. The cable company provided 2 wireless N USB adapters. What do I need to buy to plug into where in order to restore the network to its previous state? PC1 dual boots Windows 7 and Ubuntu 12. PC2 runs Debian 6. Edit: USB adapters - Netgear WNDA3200 Switch - TP-Link TL-SF1008D 8 port Ethernet switch Cabling - various patch cables cat5e rj45 Modem/Router - pretty standard cable company job - wireless Intention is something like- [modem/router] --wifi-- [some-new-hardware or perhaps to pc1] ----[switch]---[pc1/2]

  • What rights does an employer have to the employee's computer?

    - by Terrence Brannon
    What access rights should an employee grant an employer for a work computer? For instance, let's assume that the business people come to the IT lab late at night for discussions with the CIO and they use my computer for reading email and general web surfing. In a sense, this means that they are taking full or partial responsibility for any security issues that crop up that get traced back to the employee's machine. Perhaps the proper way to provide a computer to an employee is to give him full and exclusive use of it while employed. Only supervised access (such as hardware/software maintenance) should be acceptable.
