• Setting permissions on user accounts

  - by Ron Porter

  We would like to lock a couple of accounts to prevent even domain admins from resetting the password without already knowing the current password. From what I can see in the permission sets, this looks possible. Anything I've found on the subject recommends against altering default permissions, but doesn't go into detail why. Assuming that domain admin retains the ability to reset passwords without knowing current passwords is it reasonable to prevent password resets on the domain admin account and maybe a couple of others? If not, why not?

• How does one go about fixing a pixelation issue?

  - by Tyler

  I've been having a lot of trouble with pixelation and also in-game display driver crashes. At first I thought the problem may have been my graphics card (Sapphire 5750) but I have RMA'd it three times and I'm still having trouble. So what I think it might be is my PSU, its 650Watt but its made by Azza so it was cheap and not made by a necessarily good company. Or maybe it could be the CPU (AMD Phenom Black Edition 3.4Ghz) It runs hot (60C) but it passes Everest's test. Someone told me it could be the memory (8GB DDR3) but I don't really see how RAM has anything to do with my problem. So what are some of you suggestions? Here is a video a made awhile ago of what is happening. http://www.metacafe.com/watch/4392213/ati_radeon_5750/ That was just a stress test most games tend to just freeze and crash or lock my system up.

• icons in windows 7 taskbar moving by themselves

  - by valya

  I'm using Windows 7 64 bit. Few days ago I pinned another one application to taskbar and moved it to the left side. But it moved to the right by itself! I tried to return it to the left side but it went to the right again. The same thing happens now with another application (I've uninstalled the application from the first paragraph - not because of a bug, I just don't like it). It's really annoying. I want it on the left side! How to lock it in? I don't know why but it have (2) in the taskbar shortcut's name: 'Mindjet MindManager 8 (2)'

• Timeout ssh sessions after inactivity?

  - by Insyte

  PCI requirement 8.5.15 states: "If a session has been idle for more than 15 minutes, require the user to re-enter the password to re-activate the terminal." The first, and most obvious, way to deal with ssh sessions that are idling at the bash prompt is by enforcing a read-only, global $TMOUT of 900. Unfortunately, that only covers sessions sitting at the bash prompt. The spirit of the PCI spec would also require killing sessions running top/vim/etc. I've considered writing a */1 cron job that parses the output of "/usr/bin/w" and kills the associated shell, but that seems like a blunt instrument. Any ideas for something that would actually do what the spec requires and just lock the terminal? I've looked at away and vlock; they both seem great for voluntarily locking your terminal, but I need a cron/daemon task that will enforce locking.

• Best Practices in Preventing Locks in File sharing in Windows?

  - by crosenblum

  We have a web development server, that has our source control on it. That we use via mapped drives to open/edit/save/create files on to it. But I have noticed a lot of weird glitches with either the file lock/sharing/etc For example, if i have a file open on my local pc, and try to check out that file via my source control on dev, it error's out. The source control I use is QCVS by Qumasoft. Or If I use cuteftp to download something to dev, via my local pc, it won't download unless I close that file. So my brain sniff's and figures this is either an issue with folder/network/sharing, or an issue of permissions. Has anyone else had similar issues, and what did they do to fix it permanently? Thank you...

• Ubuntu Volume overriding settings set in Alsamixer

  - by Hayek

  Problem: How do I "lock in" the volume I set through alsamixer? I'm running Ubuntu 9.10. I adjusted the bass/treble columns in alsamixer but changing the system volume resets them all back to 100% I did save the settings by running alsactl store but everything is reset once I touch Ubuntu's volume icon in the top menu bar. This is rather painful because the computer is hooked up to a 650watt system with a massive subwoofer. As much as I enjoy my music, there's no need to have the walls vibrate :) What can I do to prevent Ubuntu from overriding the settings?

• windows 2000 freezing during large disk write

  - by robert

  We have a windows 2000 sp4 server which freezes up for about 1 minutes while its web-app does a ~500mb write operation. I can see the webapp start to do I/O activity (through process explorer) then the RDP session becomes unresponsive, you can click on windows and buttons but nothing happens. When the disk write finally finishes the session 'catches up' on all the mouse clicks you did during the freeze in a mad flurry of window activity and the server returns to normal. During the freeze the web-app stops as well. The same behaviour happens on the console of the server. (so I know its not a network thing) Nothing appears in the Event logs. Its like nothing happened. I have upgraded all the HP hardware drivers to the latest proliant support pack. And also run a HP hardware diagnostics which found nothing wrong. What would cause a disk write to lock the rest of the OS?

• "Computer Locked" dialog does not appear

  - by Gooch

  When I lock my computer, instead of seeing the "Computer Locked" dialog, I only see the "Unlock Computer" dialog with my user name populated and my password box has focus. I am not prompted to Ctrl+Alt+Del to first get to the "Unlock Computer" dialog. This concerns, as nearly all of my other Windows XP machines do display the "Computer Locked" dialog and force a Ctrl+Alt+Del sequence to get to the "Unlock Computer" dialog. I cannot find a setting, registry or otherwise, that addresses this. I am running Windows XP Pro (version 2002) SP3

• Why does OS X automatically logout my user?

  - by MBA_fv

  I have a new MacBook Air set up with filevault. In the Security preference pane I have "Require password 1 hour after sleep or screen saver begins" enabled, but the "Logout after 60 minutes of inactivity" is disabled. When I leave the computer on overnight I manually lock the screen (from the Keychain status menu bar, which I enabled via the Keychain Access preferences). Alas, in the morning I find that instead of a locked screen I see the login window, after my user was logged out with all applications terminated... (e.g. Firefox thinks it previously crashed when I launch it). This type of behavior only started after I enabled Filevault. Why is this happening? How do I prevent such auto-logout?

• Tracking the linux config with git: how?

  - by Pierre

  I'd like to track my linux configurations with git. My idea is to have a branch for each server. /etc is not the only one directory to be tracked (I won't git init in '/etc' ) As far as I could see, it is possible to init a git for a distant directory. I tried this: # mkdir -p /git/.git # cd /git # git --work-tree=/ --git-dir=/git/.git init Initialized empty Git repository in /git/.git/ 1) Creating a new branch before everything is not possible # git branch server1 fatal: Not a valid object name: 'HEAD'. 2) adding a file in master/HEAD is not possible # touch README.md # git add README.md fatal: Unable to create '//.git/index.lock': No such file or directory how should I properly setup git to track my system-config ? Thanks. P.

• top process state column under FreeBSD

  - by Eric DANNIELOU

  When running top interactively, I can see various word in the state column : nanslp, biord, select, uwait, lockf, pause, kqread, piperd, sbwait ... Some like nanslp or kqread are self explanatory, others are not. Tried man pages : STATE is the current state (one of "START", "RUN" (shown as "CPUn" on SMP systems), "SLEEP", "STOP", "ZOMB", "WAIT", "LOCK" or the event on which the process waits), C is the processor number on which the process is executing (visible only on SMP systems) Tried search engines : stack overflow mailing lists archives Where may I get a complete list of possible process state under FreeBSD 9, and their meanings?

• Kill xserver from command line (init 3/5 does not work)

  - by Richard Martinez

  I'm running Linux Mint 10, although I've had this same issue with other variants of Linux. I've been told/found while researching that if the X server hangs or otherwise errors, one can drop to a root prompt, usually at another tty, and execute init 3 (to drop to single user mode) and then init 5 to return to the default, graphical session. Needless to say, I've tried this before in multiple configurations on multiple machines to no avail. The only feedback I receive form executing those two commands is a listing of VMWare services (from a kernel module) that are stopped and then restarted. Note: If I run startx (either before or after init 3), then I am told that the xserver is still running and that I should remove /tmp/.X0-lock. Having tried that, it removes that error message, but claims that the xserver cannot be attached as another instance is running. How do I kill the xserver completely? Can I killall some process name?

• Keyboard doesn't work after Windows resume from sleep (S3) -- how to fix?

  - by Marco Z

  I have a weird issue with my keyboard after resuming from S3 sleep: I can type perfectly for maybe 5 seconds, but afterwards the keyboard ceases to work until I hibernate or restart (or sleep again -- see below.) The rest of my system runs just fine -- just the keyboard apparently "freezes" up. Some closer observations: The keyboard will work for 5 seconds (and freeze again) every time I resume from sleep, even if it was frozen from a previous sleep The caps lock light will work fine within the 5 seconds. But after the keyboard "freezes", the light will remain on, but I'll be unable to turn it off. Perhaps this means power wasn't cut off from the keyboard, but it's just some software freezing up the port??? Given this info, would this indicate a problem with Windows itself? Drivers, maybe? Can I rule out the BIOS as the culprit? Finally, any ideas on how to fix? Thanks! Specs: Windows 7 x64 HP tx1000 laptop

  - by user119720

  I'm having some problem with my centOS machine.I want to insert a line inside the rc.local to execute apache tomcat on startup. Below are the configuration for /etc/rc.local #!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff. touch /var/lock/subsys/local /opt/apache-jakarta/bin/startup.sh Unfortunately,the apache tomcat does not start on the boot time. I've already execute the script manually and it is working without any issues. Is there any specific syntax to put script inside the rc.local?Or did I forgetting something?Please Advice.Thanks.

• df-h command in ubuntu

  - by Esha Sharma

  I am a new user of Ubuntu. When I type df -h in terminal , it gives me list of all storage devices and space usage. In my system I get this. Filesystem Size Used Avail Use% Mounted on /cow 934M 173M 761M 19% / udev 925M 4.0K 925M 1% /dev tmpfs 374M 856K 373M 1% /run /dev/sdb1 7.5G 2.8G 4.8G 37% /cdrom /dev/loop0 1.5G 1.5G 0 100% /rofs tmpfs 934M 16K 934M 1% /tmp none 5.0M 0 5.0M 0% /run/lock none 934M 76K 934M 1% /run/shm /dev/sda 299G 74M 299G 1% /media/q I understand that /dev/sda is my hard drive which is 320 gb(in gib it is 299 and hopefully that is what is being displayed) and /dev/sdb1 is pendrive of 8gb from which I am running the live cd. My question is what are the other folders and what is the physical location of these folders if complete memory is taken by the device dev/sda?

• MySQL Cluster transaction isolation level - READ_COMMITTED

  - by Doori Bar

  I'm learning by mostly reading the documentation. Unfortunately, http://dev.mysql.com/doc/refman/5.1/en/set-transaction.html#isolevel_read-committed doesn't say anything, while it says everything. Confused? Me too. ndb engine supports only "READ_COMMITTED" transaction isolation level. A. It starts by saying "sets and reads its own fresh snapshot", which I translate to: The transaction is having a separated 'zone' which whatever it stores there - is what it reads back. B. While out-side of the transaction, the old-values are unlocked. C. It continues with: "for locking reads" sentence - No idea what it means. Question: they claim only READ_COMMITTED transaction isolation level is supported, but while handling a BLOB or a TEXT, they say the isolation is now "locked for reading" too. So is it a contradiction? can a transaction LOCK for reading just as well while handling something other than BLOB/TEXT? (such as integers)

• windows 8 on macbook locks after 2 mins despite high performance settings

  - by Mark

  I am running my Macbook Prop as a Windows 8 machine using bootcamp and for some reason, when I leave the keyboard/mouse alone for 2 mins it locks the PC (i.e. goes to the lock screen). I have (of course) checked the power settings and I can assure you that it is not set to these settings. I did notice that when I added my work's Mail Account the computer asked me to accept some group policy settings, which I did, so I suspect that this is a group policy setting, but I cannot find it. Can someone help? P.S. I have searched these forums first, and this is different to the PC going to sleep once locked, this is locking while logged in after 2 mins. Thanks.

• unexpected behaviour of Ctrl-a x and Ctrl-a X in screen?! regions, locking

  - by gojira

  According to the screen manual (version 4.0.2.) C-a x C-a C-x (lockscreen) Lock this terminal. C-a X (remove) Kill the current region. But what actually happens when I use it (Screen version 4.00.03 (FAU) 23-Oct-06): C-a X locks the terminal and asks me for the password. When I enter the correct passwword, I am back in screen but the region is killed (wtf) C-a x does nothing apparently Please note the differences between x (lowercase) and X (uppercase). Why is there a mixup between the functionalities of C-a X and C-a x? How can I fix this? I am on CentOS release 5 (Final).

• How to nmot show any prompts when inserting a USB drive in Windows?

  - by jasondavis

  1) I just found a really interesting program that allows me to use a USB drive as a windows login key. It is called Rohos Logon Key. IF I remobve my USB drive/key from the PC then I can have the PC lock or hibernate or any other option, I have been looking for such a solution for many years but never knew one existed until this and it works much better then I imagined. I do have a couple minor issues though (im using Windows 7 pro). When I remove and then re-insert my USB key, windows prompts me with this dialog here... Generally when I get this I just click on "Continue without scanning" however I am looking for a solution to just make it not even show this at all, is it possible to disable it from showing? 2) I also get this dialog as well when I insert USB drives/key... Would it be possible to not show this as well or have it pick an option by default or anything really?

• Win 8 start screen resolution

  - by Abhijith

  My screen resolution is 1280x1024 running Win 8 RP I formatted my computer and reinstalled Win 8 CP because I had too many BSODs. When I installed Win 8 CP and created a local account. I had 5(or 6) tiles per column. But once I switched to the Microsoft account to get my synced wallpaper and lock-screen, the Start screen resolution changed and I got a max 3 tiles per column. The size of all metro apps including the Settings app changed and became awkwardly bigger. Is there a way to get back 5 tiles per column? Essentially changing the resolution of the start screen?

• File/folder Write/Delete wise, is my server secure?

  - by acidzombie24

  I wanted to know if someone got access to my server by using a nonroot account, how much damage can he do? After i su someuser I used this command to find all files and folders that are writeable. find / -writable >> list.txt Here is the result. Its most /dev/something and /proc/something and these /var/lock /var/run/mysqld/mysqld.sock /var/tmp /var/lib/php5 Is my system secure? /var/tmp makes sense but i am unsure why this user has write access to those folders. Should i change them? stat /var/lib/php5 gives me 1733 which is odd. Why write access? why no read? is this some kind of weird use of a temp file?

• MS Clear Screen Saver doesn't work

  - by ufoq

  I have a problem with really exotic thing - Microsoft Clear Screen Saver. As it's name suggests, it's a screen saver, that's transparent (MS posted it as a part of W2k Resource Kit). When you move the mouse/hit a key, the "lock" dialog appears. I would like to use this to view servers desktops without need to log in. I tested it on my XP's, and it works flawlessy. But on W2K3 servers it doesn't work. After the screensaver timeout, the error message is displayed: "The Clear Screen Saver cannot display the user desktop after the workstation has been locked"

• Windows 7, how to get unlock (Press Ctrl+Alt+del) prompt on all monitors?

  - by Zugwalt

  I have a laptop that I keep shut in a docking station as I have two screens connected to the laptop and it cannot display to both of those AND its own screen. However, when my computer locks by itself (Not when I lock it using Ctrl+Alt+Del) the login prompt is ONLY on it screen (at least its there when I open it up) and my primary external monitor is off and my other one is all black. This means to log in I have to hit Ctrl+Alt+Del and blindly enter my password--which I don't mind too much, but would prefer if I could actually see the unlock/login prompt instead of typing on a black screen. Any way to have it show the login prompt on all monitors?

• Is there a simple way to make my laptop always turn on muted? [closed]

  - by tehp

  Possible Duplicate: How to mute the sound output on Windows Start up? I carry a laptop around. Sometimes I'll open it up in meetings or other quiet settings. The speaker is interrupted by the windows startup noise or Pandora refreshing it's page and starting to play a song or some other random computer noise. Is there a simple way to mute the sound on startup/resume/whatever? Kind of like the BIOS option to turn on or off the Num Lock.

• When I type certain characters, they come out as backquotes

  - by JXG

  Very strange behavior. Some background: I bought a new lenovo G550 laptop, running Windows 7. I live in Israel. When I type certain keys, in any application, they are prefaced with the backquote (`). These characters are: Insert, Delete, Left Ctrl (the right-hand one is fine), - (the regular dash: the one on the keypad is fine), =, 5 (the regular one), 4 (the one on the numeric keypad, whether or not Num Lock is on), and PgDn (the regular one). When I press the Fn key with these I don't get the behavior. Does anyone know why this is happening, or how I can fix it?
