• Combine VPN bandwith over two or more WAN connections? Load balancing?

  - by mistrfu

  Imagine you only have DSL with 5mbps Down and 2mbps Up. Is it possible to have 10 of these for example and combine them in a way that would increase the upstrean bandwidth to one server? In my head it works like this: intranet with one gateway/router router connected to multi wan load ballancer on each ballancer wan port router with vpn clinet set up, tunneling to a server ?some? software on the server in cloud joining all these connection into one interface again I would need this mostly for big uploads to a server, downlink to the office is not that important at all. Does it even make sense? I drew an image to clarify.

• Learn as much as possible about the setup behind a website.

  - by carrier

  Let's say I'm in the process of planning the setup of a website. I study similar sites that offer similar services or might receive similar traffic model. Is there a way to determine a bit the kind of setup, software and/or hardware. Some things are obvious. If I see .php or .jsp then I already know a bit. But any ideas on how to decipher more? Maybe where the site is hosted, hardware, platforms...

• Is it possible to have a cell in table1 "point to" a cell in table2?

  - by Lewray

  I have a hierarchical structure in a database driven software application. Each row in parentTable 'owns' a number of rows in childTable. If the childTable does not have a value set in columnA then it should return the value specified in the appropriate row of parentTable columnB. Is it possible to implement a pointer or cell reference somehow so that I do not have to copy values from parent to child. (A change in parent could result in a large number of changes in child). If this is not possible, could anyone suggest a different approach?

• RAID 5 heavy IO hard freezes Ubuntu: Why?

  - by Luke has no name

  I have a software RAID 5 partition on LVM in Ubuntu (desktop, actually, but I'm using it as a server). I have been rsyncing a ton of data to it, and the computer was hard freezing, as in I needed to press "Reset". So I thought it was rsync. But I decided I'd try a dd if=/dev/zero of=/path/to/raid5 and sure enough, the computer locked up. Did an identical dd to a JBOD partition on the same machine, and it didn't crash. Assuming a clean RAID5 partition, tri-core processor 2GB of ram, 6GB swap, what could be causing this?

• Where to find information about ubuntu compatible or certified hardware/PC models

  - by Halkinn

  I am buying a new desktop PC in early 2013, anyway this question should apply to someone intending to buy a new laptop/ultrabook as well. This machine is not meant for gaming, and if I ocasionally do it, I can survive with minimum graphics. However I may need some heavy multimedia edition or multitasking at times, so basically my greatest priority is a good processor, after that perhaps average graphic card (if onboards are not enough, I am still not informed enough about that), at least 4GB of RAM with possibility of expansion. I know there are some PC models specially designed to ship with Ubuntu, which is the OS I use the most these days. However, most people around me use Windows and some software with unsupported versions for Linux and not having a Windows license becomes a bit problematic. Given that, I would like to find information about which PC models or even manufacters currently on the market have the best compatibility with Ubuntu, I am still undecided between building my own desktop or buying a pre-made model, so I would like to find information both for certified models and certified hardware or even Ubuntu partners that may work closely with Canonical. Where to find this information in order to make sure that I will have a good experience with Ubuntu on my new PC in the years to come?

• Preventing apps to access info from wifi device?

  - by heaosax

  Browsers like Chrome and Firefox can use my wifi device to get information about the surrounded APs and pin point my physical location using Google Location Services, I know these browser always ask for permissions to do this, and that these features can also be "turned off". But I was wondering if there's a better way to prevent ANY application to access this information from my wifi device. I don't like anyone on the internet knowing where I live, and I am worried some software could do the same as these browsers but without asking for permissions. I am using Ubuntu 10.04.

• Is it useful check data integrity in one DAT tape?

  - by maxim

  I backup my data every day on tape using one drive DAT HP Storageworks DAT 160. I use one tape for every day and I turn them weekly. Every monday I check one tape randomly recover some files saved on it. I know that when data is saved on tape, the driver and backup software check data integrity, but I wonder if a manual check of some data saved has a sense or not. I re-use these tapes many times and I would be sure data are safe.

• Persian font in Netbeans cause speed reduction

  - by linker

  I have speed problem in Netbeans 7.0 IDE when my current open document has any Persian font inside it. If it happens, the speed of software incredibly reduce.( for example if I hit backspace, it takes about 10 seconds to respond). The amazing part is when I open a fully english document in Netbeans there is no problem and everything works well. I'm running netbeans 7.0 on Mac OS X 10.7.2. This problem happens with every fonts( even with fully Persian fonts). But I really want to have Persian with default Monospaced font. Thanks in advance.

• Altering specific configuration values in the On-Screen Keyboard of Windows 7

  - by fnst

  I have to use the On-Screen Keyboard of Windows 7 for typing: (In case you haven't used it yet, you can get it via: All Programs - Accessories - Ease of Access - On-Screen Keyboard or simply search for "osk.exe") It offers a feature to "hover" about the buttons. Microsoft describes it as the following: In hovering mode, you use a mouse or joystick to point to a key for a predefined period of time, and the selected character is typed automatically. There is my specific problem. The predefined period of time is too long to be useful for me. The minimum amount of time is 0.5 seconds (max. 3 seconds). Is there any way to alter this value to something < 0.5? For example via editing the registry? Edit: The entry *'HKEY_CURRENT_USER\Software\Microsoft\Osk\HoverPeriod'* cannot be set lower than 500 ms. Any helpful tip would be great!

• Mac OS X change IP configuration automatically by location (by Wifi network)?

  - by Seppo Sade

  Can Mac OS X be setup to automatically configure its Airport interface with a static IP address when connected to a Wifi network with a certain name, and on all other Wifi networks use DHCP? Currently I'm using the "Locations" feature of the "Network" section in System Preferences to manually switch between two IP address setups. I have a "my static IP" setup, and a default "DHCP" setup. However this requires entering System Preferences to change the Location drop-down each time when switching locations. Can this be automated? Preferably this would be done without third-party software.

• how can I get rid of duplicate administrators on 2 macbook pro's

  - by BCITY

  I got a new MacBook Pro (insurance payout) and passed my old one (previous generation MacBookPro 2008) on to a staff member whose MacBook Pro died. I used carbon copy to move my data to the new laptop but couldn't do the same with her move as the older Macbook wouldn't allow it as it was on an old OS. Ended up just migrating her software onto my old MBP. Now however, they both have the same admin identities and her computer is synching with my mobile me account. Can I change the administrator identity and save all her applications? I am hoping that I don't have to wipe and reinstall everything to change her computers identity.

• Should I be concerned that I can't program very fast without Google? [closed]

  - by seth

  Possible Duplicate: Google is good or bad for programmer? I'm currently in college to be a software engineer, and one of the main principles taught to us is how to learn for ourselves, and how to search the web when we have a doubt. This leads to a proactive attitude - when I need something, I go get it. Recently, I started wondering how much development would I be able to do without internet access and the answer bugged me quite a bit. I know the concept of the languages and how to use them, but I was amazed by how "slow" things were without having the Google to help in the development. Most of the problems I have are related to specific syntax. For example, reading and writing to a file in Java. I have done this about a dozen times in my life, yet every time I need to do it, I end up googling "read file java" and refreshing my memory. I completely understand the code and fully understand what it does, but I am sure that without Google it would take me a few tries to get the code correct. Is this normal? Should I be worried and try to change something in my programming behaviour?

• Trying to reinstalling .net framework 4 on windows server 2003 SP2

  - by LBR

  I had a problem with an application that was using .net framework 4. So I tried to fix the installation but it didn't solved. So I proceed to uninstall the framework and install it again. But then the problems started... the setup just wouldn't finish to download the framework. So i tried the full installer, and then it got stuck (freezes) at "installing client profile"... The server works well but the installation progress bar just stays at the same place (but the "wheel" keeps turning, like it was doing something, but stays like this for hours...) I tried the .net clean unistall software but the problem remains. I'm all out of ideas... I've searched the web but couldn't solve the problem with any solution I found... Any ideas on how to force the installation?

• Straight-forward to Virtualise with XEN or KVM on IBM Server System x3650 M4 791562G?

  - by ChrisZZ

  I want to built a virtualised Server Environment using XEN or KVM. The virtual machines should be purely debian systems - so XEN or KVM should be a sane choice. Now while buying servers, I am confronted with the fact, that the vendors obviously only support commercial solution. I think, on a good server, one should be able to install uncommercial software as well - but of course sometimes systems have hardware, that requires drivers, that are not found in the OS Community. So I am asked the question: Is it straight-forward to use Debian with IBM Server System x3650 M4 791562G with Debian - or even virtualising the IBM Server System x3650 M4 791562G using XEN or KVM. I am sure there will always be a way to achieve this goal - but this way might have a high milage - so I am not asking, whether this is theoretical possible, but whether this should be straight-forward and practically easy to do, no major headaches to be expected.

• Dell Inspiron7520 and ubntu 12.04 issues

  - by user91358

  I have a DELL Inspiron 7520 in the highest configuration: 3rd Generation Intel® Core™ i7-3612QM processor (6M Cache, up to 3.1 GHz) 15.6" Full High Definition (1080p) LED Display 8GB3 Dual Channel DDR3 SDRAM at 1600MHz 1TB 5400RPM SATA HDD + 32GB mSATA SSD w/Intel Smart Response Blu-ray Disc (BD) Combo (Reads BD and Writes to DVD/CD) AMD Radeon™ HD 7730M 2GB 6.09 lbs and I have installed Ubuntu 12.04 few days ago and I'm facing some issues: 1) sometimes the whole ntb freezes and I have to hold power button for 5 secs to shut it down. I think it is something with VGA and connected external monitor. I have read somewhere that it is already a reported bug, but what I am not sure about that it is doing sporadically. Sometimes it freezes right after I log in, sometime I ran few hours and then it freezes. I am using those proprietary drivers but I wasn't been able to install those with updates. 2) the next issue is the fan is quite noisy even when the ntb is almost Idle. (max 10% CPU usage). Can you recommend me some software which could do this power management to lower the noise? I have tried CPU frequency scaling indicator, but it seems that it has not any effects. 3) and issue no. 3: when I want to log out, restart or shutdown using the menu in upper right corner the upper and left trays disappear, but programs are still running and they won't close to complete log out or shutting down the OS. When I use the CLI command, it works fine. Thanks for any help you can provide.

• Block Websites at Work

  - by user791022

  At work there are about 40 PCs. I want to block all the websites and only allow a few Domains/Websites for operators. A few operators can access anything. I want something quick and easy so I can filter the Block/Allow websites for all computers from one main computer, like a server or something. Windows Vista Home and Windows 7 Home are installed on the PCs. Is there any software can do this? PS: Please don't answer about Microsoft Windows Server OS..

• Eclipse shows splash screen and closes. How to fix?

  - by Bozho

  Today I restarted my machine, and Eclipse (3.5, downloaded recently) shows a strange behaviour: shows splash screen for less than a sec quits This is in 100% of the cases, so I can't start Eclipse at all. Where can I find logs about this? I deleted all eclipse resources and re-unzipped it. Same thing. I have enough memory (IntelliJ runs fine), and my anti-virus software doesn't show any activity related to closing eclipse. Any ideas what might have caused this?

• Sennheiser PC360 Microphone Suddenly Stopped Working

  - by Michaelwm

  Just recently, my Sennheiser PC360's microphone stopped working. Yesterday Night, it was working 100% fine. Muting correctly, un-muting, volume boosting, etc. I woke up this morning, and got into a skype call (After not changing a single setting on my computer), and it wasn't working. I tried mumble, and it didn't work there either. After that, I checked my sound devices and found out it was plugged in, but not responding to my voice. I unplugged the headset, and it correctly showed that it was unplugged. So, a quick run-down: Sennheiser PC360 Headset suddenly stops working after a few hours of sleep. Software is up to date I can hear the mute sound when I raise and lower the microphone arm Windows Sound Device Manager shows that it is plugged in Unplugging the headset correctly shows it is unplugged Windows Sound Device Manager shows that the microphone isn't receiving any input

• APC UPS-5000 Power off remote servers

  - by Vishal

  Hi there, I have a UPS connected via the serial port to a server using PowerChute Business Edition. If a power outage occurs I would like this server to start shutting down all other servers within the network. Is there dedicated software to do this? I was thinking of creating a command file which runs a .bat file to run shut down commands to each server (using PSExec). I can set PowerChute to run this command file when a power failure occurs. Is there not anything APC provide which has this functionality and is more efficient than writing a .bat file to do this? Thanks,

• Windows backups to VM Esxi

  - by Martyn

  I'm very new to ESXi, so apologies if this is a silly question. I have ESXi 5.1 running running on HP Proliant Microserver with internal LUNs RAIDed with HP P410 Smart Array card. I have 2 Windows Server 2012 VMs running as Domain controllers. These are being backed-up up with GhettoVCB to a dedicated datastore hosted on LUNs on a eSata external device. I have several Windows 8 & 7 PC's connected to this domain. I want to back up these Windows PCs, via the built in backup software, ideally to the external eSata device as well. What do I need to do to have the Windows PC's see the datastore? I assume I could create a VM for FreeNas or something, or share out the datastore via one of the Windows Server 2012 VMs. Both those options seem a little bit of an over kill?

• 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?

• Netbook recomendations for a developer

  - by Joe

  I am thinking about getting a netbook for a secondary laptop. Ideally it would mainly be used for surfing/email/travel, but I would like it to be good enough to be able to run Visual Studio for when I am at conferences and the like. I as thinking it would be nice to be able to put a 16-32GB SSD in it, as well as 2GB of memory. Do you have any recomendations? Will a netbook even suffice, or should I upgrade to a small-form laptop? Edit: I don't need to be able to build software on it. It would just be nice to occasionally be able to try out new tools, APIs, or what have you without getting frustrated due to limited computing power.

• Security considerations when giving access to SQL Server db for a web application

  - by rem

  I need to expose our SQL Server 2008 database for an access from a asp.net web application. This is a new task for me, so I would like to know what basic security requirements are there for configuring software and hardware components of web server and DB Server. Is it OK to have both Web Server (Windows Server 2008) with IIS holding ASP.NET application and SQL Server 2008 on the same machine? Should I have to install additional firewall, like Forefront TMG? Should it be on separate computer? In case a web application is hosted on an external web hosting privider server and SQL Server DB on a our internal server what are "pro's" and "con's" of such configuration?

• Cannot Login as root

  - by Josh Moore

  At my work we ship our product on pre-installed servers as a software/hardware package. We are using open SUSE 10.3 for the OS and we setup and we always log in with the root user to do maintenance on the box. Recently we just had box returned to us that the customer said the could not longer connect to the box through the network interface. So when I started to work on the box I run into the this problem: At the command prompt to login i type the user name "root" and hit enter. Then even before it asks me for a password I get "Login incorrect". I have never seen this behavior before and could not find any information about it online. Does anybody know what is going on? Thanks.
