• Password not accepted when resuming from sleep

  - by Comrade

  My HP Pavilion dv-series notebook will not accept the user account password for the logged in user when resuming from sleep - message returned is Incorrect Password. Simply selecting the Switch User option reloads the login screen and allows me to log in as the same user with the same password that was originally rejected. And, yes I've tried it more than one (hundred) times in case you were thinking it's just a case of slippery fingers. Another interesting point is that it appears to be independent of the software running on the machine. Since the issue first appeared, I have done two clean installs where all HD partitions were wiped and new ones created during fresh installation of the OS. The first such clean install was of Ubuntu (Lucid) 10.04 amd-64, the second of Win 7 Pro 64 (from boxed disc and activated post install). Exactly the same symptoms, described above, are exhibited on both platforms. Have engaged in significant amount of Googling an come up empty so any ideas are welcome.

• Securing internal data accessed by a website on the big, bad internet

  - by aehiilrs

  A close relative of this question on Stack Overflow: When you have a web site in your DMZ that needs to access production data stored on an internal DB, what strategies do you recommend using to lower the risks that come from accessing live data? Is it even considered acceptable to have a connection initiated from the DMZ come inside of your network? An extra detail about the nature of the site that kind of throws a monkey wrench into the machinery is that people using the web site will be competing for "spots" on a first-come, first-serve basis with others using the internal software. Because of this, as close to zero lag time between the two applications as possible is ideal.

• Redirect channel to another speaker

  - by stex

  Hi, I'm not sure about the title but don't know how to say it in a clearer way. My Soundcard is a Creative X-Fi and I'm using the Creative console starter. Now I'd like to use my speakers not only for my normal screens but also when using a beamer. Due to my room's geometry, the only place for the beamer's projection is a wall which is right to my normal screens (so the projection would be between the front right and the rear right speaker). Now I'm thinking about redirecting the channels to the correct speakers somehow. As far as I remember, in previous version of creative console starter there was an option to do this (e.g. redirect front left to rear right output channel). Does anyone know how to do this with software? Of course I could install a cable switch, but if there's a way without I'd prefer this :) Thanks in advance.

• 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.

• 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?

• 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.

• problems establishing ssh connection

  - by Superbyte

  since two days I am facing a really weird problem. I have receantly installed ubuntu server 14.04 LTS on a workstation. It has a fix IP address, which I can successfully ping from other computers in the network. But when I try to establish a ssh connection from a windows computer via putty I get some strange errors, which I cannot fix. The Problem is that putty takes a really long time trying to establish a connection. After about 10 seconds I get the following error: Network error: Software caused connection abort But when I click the Restart Session option a several times after putty shows the error message, I can login in. But now comes the other problem. When the login appears on the putty console I type in the user, but it really takes a long time until I can type in the password to login. This is what I already tried: sshd: ALL in etc/hosts.allow commented line session optional pam_motd.so in etc/pam.d/login and etc/pam.d/sshd configured the firewall with: sudo iptables -A INPUT -p tcp --dport ssh -j ACCEPT checked if ssh server is listening on port 22 UseDNS no in etc/ssh/sshd_config I hope someone can help me, because this problem is really annoying. Thanks in regard

• What to do about "system running in low-graphics mode"?

  - by ubuntubabe

  My Dell which was 5 years old suddenly karked it and I had the "low graphics" black screen and useless dialogue box. As I believed it was a dead graphics card I went out and bought a brand new machine. I put aside the new machine and tried again in vain to open the Dell. I eventually got to the command line via Ctrl+Alt+F1. I logged into my account from there, and simply started a series of sudo apt-get remove of various softwares that I knew were installed on my PC (software without any great consequence like Google earth, tweak, Skype etc). Lo and behold after a sudo reboot my computer was fine again! So now I have 2 computers. BUT one week after buying the other one and installing 12.04 because I love Ubuntu, the SAME PROBLEM arrived! I once again deleted Google earth, Skype, and did a sudo reboot and everything worked as before. I think there is a bug or something in 12.04 as this problem has never arisen with any other versions of Ubuntu.

• What are the major distinctions between PureDarwin and FreeBSD?

  - by ??????? ???????????

  I'm looking to install a different unix on my workstation to acquire some perspective on GNU/Linux and out of curiosity. I have narrowed my options down to these two. The reason for considering PureDarwin is because I have very little experience with Apple's products. So my question is will installing and using PureDarwin give me a closer understanding of OSX than would running FreeBSD? What I have in mind are day to day routines like adding users, installing software and configuring various aspects of the underlying OS. I know that the GUI of OSX would not be available, but that is not a concern. As a secondary, less important question, can I buy OS X in the apple store and run it in a virtual machine or does that violate their EULA?

• Open Terminal Here, as Root (OS X)

  - by cwd

  There is a pretty awesome applescript called "Open Terminal Here" ( http://www.entropy.ch/software/applescript/ ) which you can add to your finder's toolbar and click when you want to launch a terminal console which is set to that directory. Sometimes I need to be root, and so I end up starting terminal, doing something like sudo -i and then I have to change back to the previous directory because the sudo command is landing me in /var/root. I'm using sudo -i because I like it to load things like aliases / the bash profile. The script is applescript, and here's the important part of how it works: ... set cmd to "cd " & quoted form of the_path & " && echo $'\\ec'" ... tell application "Terminal" activate do script with command cmd How do I get this to load as root?

• 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?

• 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?

• How can I monitor network traffic in an all Mac home network?

  - by raiglstorfer

  I have an all Mac network consisting of an Airport Extreme, 1 MacPro, 1 Mac Mini, 2 MackBook Pros, 2 iPads, and 2 iPhones. The Mac Pro is connected directly to the Airport Extreme via Cat5 and the rest is all running via Wireless. Lately I've been getting prompted by Google to enter Capchas frequently. The message states that I might have software running on my network I'm not aware of. My wireless router is password protected using WPA2 Personal and I frequently change my password so I don't think someone is using the network from outside (but I've no way to confirm this). I'm looking for a relatively cheap (preferably open source) solution that would enable me to monitor and profile the network usage by machine and port. Can someone recommend a solution?

• 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,

• 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?

• 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.

• reverse-proxy web access on a server where only SSH is allowed

  - by Kaii

  Every once in a while i have to connect to a server where access is highly restricted. Only inbound SSH is allowed by the DMZ firewall - outbound HTTP connections are blocked. I'm looking for a good way to tunnel web access through my SSH session, so i can install updates and software via yum / apt-get. What do you do in such a situation? SSH has the -D <port> SOCKS proxy option. But unfortunately it is one-way only from client to server and there is no reverse option.

• 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?

• 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.

• 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...

• 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.

• 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!

• HTTP Live Streaming Broadcast

  - by user761389

  I'm designing an app for streaming video from a device (e.g. iPhone) via a server to one or more devices and have been researching Apples HTTP Live Streaming protocol. One thing that isn't clear is whether it is possible to stream live video (with audio) to the server and then have it streamed simultaneously in real time to the client devices. From reading the documentation and technical notes from Apple it seems like the index file needs to be created before the segmented video files can be served to a client. Is this right? If so maybe HTTP Live Streaming isn't suitable in this case, what other technologies or software should I consider? Thanks

• Do HTTP reverse proxies typically enable HTTP Keep-Alive on the client side of the proxied connection and not on the server side?

  - by LostInComputer

  HAProxy has the ability to enable HTTP keep-alive on the client side (client <- HAProxy) but disable it on the server side (HAProxy <- server). Some of our clients connect to our web service via satellite so the latency is ~600ms and I think that by enabling keep-alive, it will speed things up a bit. Am I right? Is this supported by Nginx? Is this a widely implemented feature in other software and hardware load balancers? What else besides HAProxy?
