• vpn/Openvpn as a cloud service

  - by 8pipe

  I am working on creating a small cloud (any number of EC2 instances that can be deployed based on load) implementing a VPN as a service for the company I'm working for. This is basically a project gathering together various vpn resources under one aegis as a cloud based service. As a user of openvpn, I'm somewhat familiar with being able to connect, but I'm looking for resources to start this project. Essentially I need to be able to: run a certificate authority and manage keys to distribute to coworkers build an ami that handles openvpn as a service balance the load if necessary among machines instances as needed Any suggestions for tutorials, things to avoid, roadblocks I might not be seeing from a novice perspective, etc. or just help in visualizing this is appreciated.

• Notepad/Edit equivalent for Linux command line

  - by Jason Kester

  I'm looking for a simple text editor that I can use from the command line in Linux to edit files. I'm used to editing files in windows, so I'm looking for something with the same keyboard interface. That means: SHIFT+Arrow Keys/PGUP/PGDN to select text CTRL+C, CTRL+X, CTRL+V to copy/cut/paste And that's pretty much it. Surprisingly I'm having a tough time finding something like this. Vi/emacs are naturally out. Nano comes close, but has its own non-standard cut/paste/select keyboard shortcuts. Surely this thing exists somewhere. Thanks in advance for pointing me in the right direction.

• How can I get Windows 8 to automatically disable touch when I am using my Wacom pen and turn it back on when I am not

  - by Robert

  I have an HP convertible tablet computer which I just upgraded to Windows 8. The problem (which existed under Windows 7 as well) is that this tablet has both a capacitive touch screen (with multi-touch) AND a wacom-type tablet built in to the screen that works using electro-magnetic resonance with the provided stylus. My Use Case: Most of the time I am happy using my fingers and the touch interface for navigation and whatnot. However, when I want to get down to serious note-taking/drawing, I want to use the wacom functionality. The problem is that any comfortable writing position has me resting my arm/hand on the screen, which activates the touch technology (despite supposed palm-detection algorithms) and completely screws up my input paradigm. My Ideal Solution: Ideallly, since wacom technology senses when the pen is "close" to the screen, I would love to have touch be automatically disabled whenever the wacom pen is detected, and turned back on when it is out of range. this would allow me to seamless switch between the two input methods, and since I NEVER want to use both at once would work perfectly for me. An acceptable alternative: As a next best option, It would be great to be able to turn off the touch functionality (leaving the wacom in place) whenever I entered specific apps (e.g. OneNote, Photoshop, Gimp, Pencil, etc.) and then have it turn back on when I left that app.... As a worst case at least lets me use my PC option: If I could create a shortcut (tile or otherwise) that flips the touch on and off without going all the way through the nested computer settings, that would be better than nothing. Thanks in advance for the help with 1 or more of the above.

• Why does my PC sometimes think I am constantly pressing the control key?

  - by David Faux

  I was browsing the web with Chrome and pressed f. A search box appeared. I then pressed s, after which Chrome asked if I wanted to save the web page. I soon realized that my PC was thinking that I was constantly pressing the Ctrl key regardless of what program I was using. In response, I tried clicking both of my Ctrl keys a few times to no avail. This problem arises sporadically as I work. I am not sure what is triggering it. Why could this problem be occurring? Is it the keyboard or software? How should I respond?

• Brightness too dark or too bright

  - by YatharthROCK

  Basically, below a seemingly-arbitrary threshold (seems to be around 60%) my laptop screen is too dark to really make out much, and above that threshold it takes its maximum brightness (which is waay too bright for my eyes). This problem only occurs when I change the brightness using Windows' UI. Changing the brightness using Fn keys on my keyboard works as expected; unless the screen went into dark mode because of Windows, in which case they have no effect. This problem started occuring on my ASUS laptop very recently. My laptop has a poor battery, but I don't think that's related. What is going on? I tried resetting power plan settings, turning off adaptive brightness and restarting. I'll give any info asked for. Help required urgently...

• Detect damage done by virus

  - by user38471

  Hey, this morning after I went to college a virus infected my pc without any user interaction at my end. When I came home my computer was completely frozen and infected with lots of trojans. I have not typed anything important since returning so keys cannot be logged. However I want to know exactly when my computer crashed from the time of infection to see what could potentially be done remotely by a hacker. The virus my pc was diagonosed with was "fakespypro" http://www.microsoft.com/security/portal/Threat/Encyclopedia/Entry.aspx?Name=Win32%2fFakeSpypro on a fully updated windows 7 installation with firewall enabled. My computer was connected to an internal dorm room network, so probably that has had to do something with it. Any further information about how I could backtrace this virus infection or ways to discover what data might be stolen would be greatly appriciated.

• I get regular power surges and my UPS ticks a lot due to a welding plant. Is this good or bad?

  - by EApubs

  In our home, there is a mechanic who often use a welding plant. When he use it, I think we get a power surge. My UPS ticks madly (not beep, it ticks). Sometimes, I even lose power to the keyboard. When typing, some keys get missing. 1) My question is, is it good for the computer? The UPS claimed to have surge protection. But isn't it working? What should I do to protect my PC? 2) The second question is, I also have a broadband router which is not connected to the UPS. Will it be effected?

• Ubuntu - No gnome-panels, no right-click, no internet, no hotkeys

  - by Darthfett

  Hey guys, I've been using Ubuntu (Maverick 10.10) on my desktop (ATI Radeon 5830) for about 3 weeks now, but all of a sudden I am unable to even use my computer. As soon as I start up, I see my desktop, with icons, but I don't see any gnome-panels, and I'm unable to get any options if I right-click. I can start programs by double clicking them. I also cannot get an internet connection. I've tried restarting gnome-panel by killing it, using Ctrl+Alt+5 to switch to a terminal (I don't have a shortcut to one on my desktop, and no hotkeys will work), but no luck. Restarting my computer has no effect upon this (I have to manually cut the power, since I don't know the terminal command). As far as I know, I have not made any changes, and I've never had any problems in the past. This started when I was playing Minecraft, but my internet crapped out, and no amount of re-trying the connection would work. I know it was my computer, as my brother's was working fine in the other room. Any clues as to what's going on? I'm more than willing to troubleshoot.

• Getting error while running apt-get update

  - by pradeepchhetri

  I am getting the following error while running apt-get update on all of the servers. W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 8B48AA6247928553 W: Some index files failed to download, they have been ignored, or old ones used instead. The solutions available are: To login into each of the server and run the following command to import the gpg key for that repo. sudo gpg --keyserver hkp://subkeys.pgp.net --recv-keys 8B48AA6247928553 sudo gpg --export --armor 8B48AA6247928553 | sudo apt-key add - But this requires logging into all of the individual servers and run the above two commands. I am looking for a way to correct by working on apt-repo server. Is there any way to do that.

• Google reader Keyboard shortcuts not working in Firefox 3.6

  - by Jj

  I just upgraded to Ubuntu 10.04 which comes with Firefox 3.6.3. Now Google reader some keyboard shortcuts stopped working, The j/k keys are ok, but 'v', 'Shift+x' and others don't work and start the Search As You type functionality I've always used. The Javascript console only shows this warning: Warning: The 'charCode' property of a keyup event should not be used. The value is meaningless. Source File: http://www.google.com/reader/view/?tab=my#overview-page Line: 0 This did not happen with Firefox 3.5.x even though I've always had the Search as you type option enabled.

• How to make ssh-agent automatically add the key on demand?

  - by Vi.

  I want to run ssh-agent (with maximum lifetime option), but not add any keys at startup, but instead add them on demand. Like first time I login to some server it should ask for passphrase, next time (unless I waited for more than a hour) it should connect cleanly: ssh server1 Enter passphrase for key '/home/vi/.ssh/id_dsa': server1> ... ssh server2 server2> # no passphrase this time # wait for lifetime ssh server2 Enter passphrase for key '/home/vi/.ssh/id_dsa': I don't want to manually remember about running 'ssh-add' each time. (e.g. entered passphrase for just for ssh and "Oh, it hasn't remembered, need to retype"). How to configure ssh to automatically add key to ssh-agent if user provided the passphrase?

• Private key authentication with pam_ldap

  - by Gareth

  I'd like to set up pam_ldap on some of our servers so that we can centrally manage who has access to which server, and easily revoke access if e.g. someone leaves the company. I've done some research and got this working. Hooray! However I'd also like to be able to use public-private key logins - i.e. allow users to store their public keys in the LDAP directory and have these work for logins too. I can't find any documentation about being able to do this, but I also can't find any reasons that it shouldn't be possible. Is there a way to do it, or is there some fundamental reason that it won't work?

• Is there any program (or code, any language) that will mute all of the microphones on my computer?

  - by Sean

  Is there any program (or code, any language) that will mute all of the microphones on my computer? If it is code, please make it as simple as possible, the only language I know is C# and I am still VERY new to it. I just want to setup some way to mute my microphones from a hotkey/shortcut, and if I can just find a program that can do, I will be set. As I said, I can also do a little bit if it is in C#, but the only code I have seen before for this, was miles long (atleast to me). My goal, is I just want a program that opens up, and toggles the mute on the microhpones (all of the system audio input) then closes. That is it, very simple. Thank you to anyone who trys to helps me! EDIT: Yes, I am using Windows. I am using Windows 7 32-bit. I already know that I can go into the volume mixer and do it that way, but I need to do this while running a full screen application, and it is a hassle to have to exit fullscreen, open the volume mixer, the click the mute icon, then go back into full screen and the the whole thing over again to unmute it. And I will be toggling back and forth quite often, so it just takes alot to do that so much.

• How can I make Windows Media Player ignore global hotkeys in Windows 7?

  - by Schnapple

  I have Windows 7 and a Logitech G15 keyboard. One of the programs with the Logitech G15 allows you to control media players such as Winamp with the playback keys on the keyboard. Problem I'm having is that, even though I have told this program to not control Windows Media Player, every time I use it to pause Winamp, it then hits plays (or unpauses) Windows Media Player. Even more annoying given that Windows Media Player isn't even running as an active GUI program and instead as a background process, so I hear the sound of whatever the last video it was I playing. If I end-task wmplayer.exe it spins right back up but at least now it has no knowledge of a video to play, but this is annoying. How can I either a) Have Windows Media Player in Windows 7 completely unload when I close it, or b) Have Windows Media Player in Windows 7 ignore any sort of global hotkeys?

• Remap key combinations in Windows

  - by nickf

  This question is similar to this one, but the accepted solution doesn't work in my case. I work on two different laptops. On one, the Home and End keys are only available by pressing Fn+Left and Fn+Right. This can make it rather annoying when switching between the two since I always go to press Fn-Right and not get what I want. The tool suggested in the other question is Sharpkeys, however it doesn't recognise Fn+Right as a different key from Right, and I suspect that registry twiddling isn't going to help me here. (?) Is there any way to remap this combination? (I'm on Windows Vista if that helps)

• Mapping capslock to control on Mac OS X: works for some things, but not others?

  - by keflavich

  I've mapped my capslock key to control using the Modifier Keys mapping in System Preferences: Keyboard. I've also tried mapping to "right control" instead of "left control" as per http://hints.macworld.com/article.php?story=20060825072451882 using a plist editor. The mapping seems to work in all cases except one: I can't use capslock with left-shift to make key mappings or apparently do anything else. capslock (as control) with right-shift works. I'm primarily testing by using control-tab / control-shift-tab to switch between tabs. Using the on-screen-keyboard viewer, I can get capslock-shift-(just about anything) to work, but not capslock-leftshift-tab. My best guess is that somehow the particular keyboard I'm working on is faulty, but I'm curious whether anyone else can reproduce this or has any ideas.

• Cannot delete podcast from iPod Touch

  - by rybl

  I am having a problem with my iPod/iTunes where an episode of a single podcast cannot be deleted. The episode in question does not show up in iTunes or as being on the iPod when I drill down and look at the podcasts on the iPod in iTunes. It also does not play if I try to play it on the iPod; it just waits a second and skips to the next podcast. I have iTunes 9.2.0.61, my iPod has OS version 4 (although I was having this problem before I upgraded), and Windows 7 64bit. I would really prefer a solution that does not require me to completely wipe the iPod because I have a bunch of WiFi keys stored that I don't want to have to dig up again.

• SQL Server Configuration Manager menu won't show up

  - by Aurelien Gasser

  I'm running a Windows 8 VM on a MacBook using Parallels Desktop 9. On this Windows VM, I have a SQL Server instance running perfectly. However, when I launch SQL Server Configuration Manager, and I want to enable an IP configuration, the Enable menu options are invisible : Here is a screenshot : http://i.imgur.com/PY7qGup.png (I don't have enough reputation to display the image inline) When I click the arrow, a contextual menu should appear with 2 choices "Yes" or "No". Instead, a tiny contextual menu appears, but it's empty. I tried using my keyboard tab/space/arrows keys without success. Has anyone faced/solved the same problem ?

• Control Panel as menu includes a blank item

  - by Matthew Ferreira

  When viewed as a menu attached to the Start Menu in Windows 7 Ultimate x64, the Control Panel contains a blank item. It looks like this: This item cannot be deleted or removed. I also cannot create a shortcut to it. No error message is displayed, instead simply nothing happens. I've tried using Shell Object Editor (using Run as Administrator) to find out if there is an errant entry on the Control Panel, but many entries (almost two dozen) are blank. There are several valid entries as well. I've looked through the registry and through C:\Windows, \system32, and \SysWOW64 but have had no success. I looked at this question, but I am not using Windows XP and thus have no option to use Tweak UI's Rebuild Icons function. Please note that this is no empty entry in the Control Panel when opened normally, only when attached to the Start Menu as a menu. I have compared the list of entries on the attached menu to the normal Control Panel and other than the blank entry, they are exactly the same. Nothing is missing from one or the other. I've also compared the menu and the normal view to reference images and lists of Control Panel items and have found no irregularities. Is anyone familiar with this problem or know of a solution? I've performed virus and malware scans and found nothing. I've used CCleaner with no change. Nothing with Shell Object Editor. Nothing with Registry Editor. Certainly someone here knows how to fix this. My only guess is the many blank entries visible in Shell Object Editor, but I am reluctant to delete that many items without further analysis and guidance. I appreciate your time and consideration.

• Outlook Security Alert following Exchange 2007 upgrade to SP2

  - by desiny

  Following an update to Exchange 2007 sp2 (yes I know very belated) I have an issues when logging onto Outlook. I see the below message... I also had a simlar issues with web access and as I am at home with IIS, this was easily solved. However I did notice that the server contains a number of keys for autodiscover.mycompamy.com, exchange.mycompamy.com etc and it seems that the SP2 upgraded didnt know how to deal with this. As I have a wildcard ssl, I think it would be prudent to remove all other certificates, however in order to stop the nag when opening outlook - what can I do?

• Localized database for customers

  - by Jim

  The company I work for, has just moved to AWS - and currently they have one very large central database with the instance currently located in America. However, one of their clients has requested that all of their data is held in the EU. So creating an AWS instance in Ireland isn't a problem, the problem is the database and how to manage it. We were considering having another database that runs in the EU for European customers, and use a different primary key step, so that the primary keys will never conflict in case the two locations need to be merged in the future. The problem is, if we have a customer that uses our system in both America, and the EU we would have to create 2 accounts for that user, and reporting across both regions would not be possible as the connection time would be too high. Is there an alternative to set this up?
