• Corrupt file indicative of corrupt hard drive?

  - by Elipsicon

  I have noticed that two files on my (almost full) 2 TB hard drive have been corrupted. One file has 20 kB (!) corrupted, i.e. consecutive 20 kB have changed, even though the modification date of the file hasn't changed and I haven't worked with this file for over a year. This tells me that something "below" the file system level has messed with the data and the only thing I can think of is hardware failure, most likely hard disk failure. I've tested my RAM already and it works flawlessly. I'm using ext4 on Linux, if that is of any help. Is this normal? Is it time to change my hard drive disk before something worse happens? What can I do to prevent that from happening in the future? Is there some built-in feature of, or extension to ext4 that includes additional error correcting code and/or watches files for changes that haven't been caused by the OS?

• Black GUI with minimal desktop icons appeared after powering on my desktop PC

  - by Christopher Chipps

  My computer powered on fine but after POST, a dialog box appeared with a red "X" and it gave some sort of warning. It had a long file name, I cannot recollect the entirety of it but it was something like C:/system32/desktop....After clicking ok, the GUI was totally black with only the Recycle Bin icon in the Desktop, and the Taskbar was there as well. I restarted it, and the GUI was back to normal with the icons and wallpaper in their proper place. I'm sure if I knew more of that file name in the dialog box, that would be helpful to those reading this but should I be concerned that this happened?

• Looking for Driver Diagnostic and Repair Software

  - by risingTide

  Greetings, I am currently plagued with BSODS on startup (both normal and safe mode) for my XP Pro. After much troubleshooting I have determined it is a driver problem. However, because I cannot even boot I do not know how to fix it. I am looking for some specific driver diagnostic and repair software that I can use from another computer to access and fix the driver problem on the problematic XP drive. (I can access the problematic drive via USB from another computer.) I will offer more details about my specific situation if it is helpful or necessary. Thank you for your time!

• Microsoft word slow switching and safe mode

  - by huggie

  I don't know what I did, but recently when I opened Microsoft Word document, I experienced very slow app switch between it and other applications. When I start Word in Word's safe mode (as described here http://wordprocessing.about.com/od/troubleshootin1/qt/safemode.htm ), the issue disappears. Now I don't know where to find out which plugins were loaded that's causing the problem. Or where the normal.dot is if that's the problem. I'm on Windows 7 64 bit. Thanks.

• git init --bare permission denied on 16gb USB stick

  - by Sour Lemon

  I am using GIT on a Windows 7 machine (64 bit) and have been learning how to use GIT to version control my files. Now I want to be able to create a --bare repository on an external device (in this case a 16gb USB stick) but unfortunately when I try to create a --bare repository on it I get the following error: f:/: Permission denied I am using the GIT Bash program which is installed with GIT on Windows machines, so these are the commands I am typing in (I am also opening the program as administrator by holding ctrl + shift when I open it) cd /f git init --bare f:/: Permission denied However if I create a normal repository it works just fine: cd /f git init Initialized empty repository in f:/.git/ Can anybody shed some light on why I can't create a --bare repository? Any help would be much appreciated.

• PIN based Login in Windows 8.1 Missing

  - by WiredPrairie

  I installed a fresh copy of Windows 8.1 Pro using Hyper-V, and updated with all updates via Windows Update. It's not domain joined. I cannot however activate a PIN based login for the installation and I'm not sure why. I'm using a Microsoft account to login (not just a local login). I have even manually enabled the feature using group policy (which apparently only should have mattered for a domain joined workstation anyway), rebooted, and it's still not available. As far as I can tell, everything else seems normal and is working as expected. For Sign-in options, I only see Password as a choice:

• How do I stop apps trying to use a dial-up connection?

  - by ProfKaos

  Every now and again, I might have to use a dial-up internet connection via another tethered phone, i.e. Bluetooth connection to the GPRS modem. Now I am back on 'ops normal', i.e. using a shared internet connection on my own phone, or on my 3G stick, but some apps, especially IE9, keep popping up a 'dialup connection' dialogue, which I cannot dismiss enough times ever, to make to stay away. How can I tell these idiot applications that I no longer need a dial-up connection?

• Event Viewer shows service name as a truncated 8 character name

  - by Retrocoder

  I have written a service which logs to the Windows Event Log when it has any problems. This works fine and the service name is shown correctly in the Source column of the Event Viewer. The problem I am seeing is when my service hits some major problems like the networking layer has died etc. When this happens the event log shows errors about my service but the service name is shown as a truncated 8 character name. This name looks to be that of the executable and not the service name. Is this normal behaviour for a truncated name to be show ?

• How do I run unsigned driver permanently?

  - by acidzombie24

  I compiled my own truecrypt for windows and doing the suggested F8 to run unsigned drivers worked. I was able to install and run truecrypt successfully. However when i restart the machine and let it boot normally I can no longer use truecrypt because of unsigned drivers even though I have it installed. What can I do to boot normally and use my build of truecrypt? Can i modify the registry, add an exception, can i sign my own driver without paying anything (but it probably only work on my machine which is 100% fine), What can i do to run my own truecrypt build on a normal bootup?

• Server only powers (but doesn't POST) when IDE drive is powered

  - by Jookia

  So after a thunderstorm last night which did a little damage, a Gigabyte server has decided it's going on power on but not POST. If it is POSTing, it's doing a very bad job at telling me. No beeps, nothing. Power seems to reach the components though. CD Drive opens and closes. So after stripping it back, I've found that the difference between this behaviour and deciding it's not going to power on for more than half a second, is having a power cable plugged in to one of the IDE hard drives. Is this normal, or a sign that the PSU has had it?

• Office communicator voice chat

  - by Gareth Simpson

  My company recently mandated a switch from Skype to Office Communicator for IM / voice chat. While Skype was never the be all and end all of VOIP, it was at least usable. With Communicator, if one person is talking, everyone else is basically silent (or as good as) so a normal conversation is impossible. No one can interrupt anyone else, if two people start talking at once it's a crap shoot who gets to be heard and often the person who is inaudible doesn't know it. There do not seem to be any client side settings to fix this. Is there anything that can be done server side or is it just rubbish?

• Removing port forwardings programmatically on a ControlMaster SSH session

  - by aef

  Quite a while ago I got an answer telling me how to add a port-forwarding on a running SSH ControlMaster process. To know that helps a lot, but I'm still missing a way to remove such a port forwarding after I don't need that anymore. As far as I know, you can do that through the internal command key sequence on normal connections, this seems to be disabled for ControlMaster clients. Even if that would be possible I would need a solution which I can automatize with scripts, which is surely not so easy this way. Is there a way to do it? And is it easily automatizable?

• What happens to modern-ui apps when they aren't in the foreground?

  - by Mark Allen

  If I start a modern-ui app and then switch to a different app or a normal program running on the desktop, what happens to the first app? I've heard something about the first app being suspended, but realized that I don't really know that for certain. I mean, could you write a SETI@Home (BOINC) app if you wanted to, or will apps that aren't in the foreground always be suspended? Can you change that? I could see changing that based on available resources, running from AC vs. battery, etc. This morning I heard about an iPad being recovered thanks to the "Find my iPad" app, and was wondering whether you could write such a thing as a modern-ui app and have it work without being the running foreground app. (I'm aware that you'd just write a Windows service or similar, that's not what I'm asking about.)

• Windows 2003 SP1 terminal server printers Disappear after reboot - HP laserjet 4240

  - by Alex

  had working PCL6 laserjet 4240 driver. needed to downgrade to PCl5, tried but did not get clean install. tried again and it seemed to work (this is 2003 enterprise terminal server SP2) Have over 40 working laserjets (5, 4000, 4100 and 18 of the 4240) After normal nightly reboot the 18 4240 printers were 'gone'. Worked w/Microsoft who said bad HP driver issues - weird since they work on other terminal servers. downloaded latest version, etc. from HP site and can NOT get to work. As soon as I install, then do a Net Stop Spool and Net Start Spooler the printer is 'gone'. Current workaround is to use HP 4000 PCL5 drivers for all of these 4240 printers.

• Apache SSL Log Incomplete SSL Handshake

  - by Raymond Berg

  Scenario: We're running some experiments in our classroom around trusted connections and SSL, and I want to demonstrate the SSL handshake request on a man-in-the-middle attack. I have an Apache server with a self-signed cert. Everything works fine, but the logging seems incomplete as there is no way to get a list of SSL attempts. Once the client accepts the 'exception', I get normal access log messages for every request. However, I need to know what ssl request caused it to fail. Here are my log directives: LogLevel warn ErrorLog logs/ssl_error_log CustomLog logs/ssl_access_log combined #the combined is your average custom log My desire is a list of every SSL handshake attempted. What am I missing that could produce something like the following? (Obviously the exact words aren't needed, but in the ballpark) 0/0/0 00:00:00 - 192.168.1.10 - hijk.lmnop.edu - SSL Mismatch

• Should DKIM signing happen in the application or the MTA?

  - by thomasrutter

  I'm trying to weigh up whether DKIM signing should be done by the application sending mail (for instance, the mailing list software you're using) or at the mail transfer agent (sendmail, postfix etc). Do you know any good arguments either way? As far as I can see, doing it at the MTA, such as with dkim-milter, is a lot easier to set up. However, if anyone gets access to the server, even just a normal unprivileged account such as a web hosting client's login, they'd be able to send email using sendmail and get the full blessing of my DKIM signature. What do you think is the best solution for my situation? I'm using a Debian server with apache, postfix, php&mysql, etc.

• Port forwarding no longer works

  - by Auryn

  Prior to testing an OpenVPN installation, I setup a basic VPN server using the software already built into Windows 7. Port forwarding on the Linksys router worked as normal and I was able to connect remotely. After doing an install of OpenVPN Access Server on a spare box running Ubuntu, and adding new ports to be forwarded I was unable to access the VPN from an external source as the required ports all indicated that they were closed. (During testing XRDP and VNCSERVER were also installed to facilitate access to the box) Checking back on the Windows 7 VPN resulted in no access to that vpn setup either. All ports are now reporting a being closed despite being previously open even ports that were being used for other services. Adding and removing port forwarding rules seem to have no effect. At this point, in order to troubleshoot, both the firewall and anti-virus software have been disabled on the Windows 7 machine. Could this be just a router issue? Is there any way out of this without having to reset and reconfigure the router?

• Fine control over zoom and aspect ratio in VLC player

  - by ashh

  In VLC Player (v1.01), how do I zoom video and control aspect ratio with fine control, as is possible with Media Player Classic Home Cinema (MPCHC)? The standard zoom appears to only support double, normal, quarter size etc, not useful to me at all. An example: I play an older music video file that is in 4:3 aspect ratio. In MPCHC I can use the number pad to zoom in small increments until I have removed the left and right letterbox bars and the video fills the whole screen. I can also stretch and move the video in small increments until I am happy with the aspect ratio and position. I could continue using MPCHC, but I have two displays and really like VLC feature enabling full-screen video on the main screen and the VLC interface (menus etc) on the second. I have not found a way to do this on MPCHC, if anyone knows I'd also be interested to hear.

• How to temporarily stop web pages intercepting a right-click?

  - by callum

  Some websites like Google Drive intercept right-clicks and provide their own context menu. This is usually what I want, but sometimes I still want to do a normal, native browser right-click. Is there any modifier key or something like that to make it so a right-click doesn't trigger a click event on the web page, so it can't show it's context menu? I want to do this per-click, not by changing a setting somewhere. If there are different techniques depending on browser/OS, please list them.

• SSH via DHCP server

  - by SFault

  I have a DHCP server setup and I can't seem to connect to anything through SSH. When I'm logged in to the server itself, I can SSH. But when I connect any machine to the DHCP server, that machine can SSH but every server I SSH to asks for a password when the normal behavior (when not connected to the DHCP server) does not. Here are the contents of my iptables script that are related to port 22. $IPT -t nat -A PREROUTING -i $LAN -p tcp --dport 22 -j REDIRECT --to-port 22 $IPT -A FORWARD -i $LAN -p tcp --dport 22 -j ACCEPT $IPT -A INPUT -i $LAN -p tcp --dport 22 -j ACCEPT $IPT -A INPUT -i $WAN -p tcp --dport 22 -j ACCEPT $IPT -A OUTPUT -p tcp --sport 22 -m state --state ESTABLISHED -j ACCEPT $IPT -A INPUT -i $LAN -p tcp --dport 22 -m state --state NEW,ESTABLISHED -j ACCEPT Am I missing something?

• Some people suddenly say they cant access my site, but me and all others can

  - by Cain

  I have had this problem many times before and im still unable to find out what is causing it. It happned to me some months ago but it got fixed by itself and had already gone back to normal. Everything was working fine for quite a while until 2 days ago. Some people are reporting they cant access my site, they get a 404 error, however i can access it normally and many other users cant. I dont know whats the common denominator since both groups of people are from the same countries, use the same browsers, OS, etc. so the issue doesnt seem related to that. I have reported this problem before to my both my host and domain registrar but none of them claim responsibility for that. Who is then to blame? Waht can i do to find out whats causing the issue and solve it? Thank you.

• How do I format an SSD to be used as the hibernation drive? (Acer S3)

  - by Craig Caro

  I have an Acer Aspire S3 ultrabook. It comes with two separate drives, one 320 gb hdd and a 20 gb ssd, which Windows uses for hibernation. I formatted the SSD and installed Ubuntu on it. How do I format the SSD so that Windows recognizes the SSD as the hibernation drive, like the way it came out of the box? Acer really had an interesting way of using the SSD. I'm just trying to get the laptop ready to sell, so I figured I would get it back to normal.

• Intel Core i7-4960HQ vs. 4850HQ (Haswell) [on hold]

  - by Timothy R. Butler

  I'm looking at the new MacBook Pros and trying to decide between the Core i7-4960HQ (2.6 GHz) and i7-4850 (2.3 GHz). I've found some synthetic benchmarks comparing them, but I haven't found a lot of data, so I'd appreciate any pointers to good comparisons for the Haswell family (especially these two processors). My cursory analysis seems to suggest there isn't a huge gain from the extra 300 MHz. I'd like to determine not only whether this is generally true, but also to figure out if the gains that are made in performance come at too high of cost. Is the 2.6 going to be pushing the limits of what can fit in a thin laptop without overheating? I've looked at some of Intel's documentation, but have not been able to determine what the normal and maximum operating temperature differences are for the models. In the past, there have been times that Intel's fastest models in a given range ran especially hot and/or consumed significantly more power compared to slightly slower models. Do those concerns factor into the current generation?

• Windows 7 system intermittent freezes

  - by lang2

  I've been using a new laptop with Windows 7 professional. Occasionally, the whole system will lock up for a few seconds before it comes back to normal. During the freeze, mouse can't be moved, keys are not recognized, music playback stops.... it's like there is a global mutex been locked on and not released. A easy way to reproduce this is to minimized the current window. It doesn't happen 100% but it's quite very annoying. Any help to get rid of this is much appreciated. lang2
