• Cloning OpenVZ container

  - by Tiffany Walker

  I have an OpenVZ container on 1 host and I would like to clone it over to my server. both run SolusVM. I only have root access to my server and would like to host the container on my server now. Can I use rsync to clone the drive while the OS is running on both? Using a command like this: rsync -uazPx --exclude='/boot' --exclude='/proc' --exclude='/dev' --exclude='/lib' --exclude='/tmp' --exclude='/var/lock' / [email protected]:/ Is there any other areas I should probably not copy over?

• How to resolve problematic vnc/xming clipboard interaction?

  - by frankc

  I often have both a VNC client window and several X windows open (via Xming) at the same time on my Windows XP desktop. When this happens, the X windows, especially emacs and firefox, often lock up or behave erratically. I am pretty sure I have narrowed this down to contention over the clipboard. I wasn't really able to find any options controlling this behavior in either Xming or VNC. Is there a solution to this problem? Right now, I have to close VNC when I am actively using emacs...

• Why can't I defragment my SQL 2008 .mdf file?

  - by LesterDove

  I am defragmenting a badly (95%) fragmented drive upon which large (35 gig) SQL Server 2008 .mdf files live. After defragmenting and viewing the exception report, I see that the production .mdf file that I'm most interested in could not be defragmented. I initially figured it was because MSSQL had an exclusive lock on the file, so I detached it and tried again. No luck - this particular .mdf file could not be defragmented. What am I missing? Most online references suggest that I should be able to file defrag an .mdf A note: yes, I'm talking about file defragmentation, not index defrag, which is already being done routinely, and which I'll re-run after this. Thanks! What am I missing?

• Is there a way to force/manage file locking in windows?

  - by JPbuntu

  I have a 2 Windows machines networked and I am having trouble with simultaneous access to files. I would like only one user to be able to open a file at a time, which I thought was automatic, using file locks.... if the program used to access the file is locking the file. I believe the problem I am having is some of the programs I use, don't lock the file, and there for can be modified simultaneously by multiple users, which is very much not desired. Currently I am having this problem with only two computers, although as soon as I can figure out a solution to this problem the network is going to be expanded to 6 computers, which will include Windows 7, Vista, and XP, as well as a central file server (Samba). Is there a way to ensure that all files opened in windows get locked? Any suggestions are appreciated, thanks.

• 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?

• what are the vulnerabilities installing openvpn client on a customer's unattended server?

  - by senorsmile

  We run Pfsense as our primary firewall. We also have OpenVPN server running on that box to allow us to remotely connect to our network. My question is: if we have a customer's mostly unattended server that we want to access remotely, what security vulnerabilities are there to installing openvpn on the customer's server as a client connecting to our network. Presumably, we would want to limit/restrict that server's access to the rest of our network. How do we lock openvpn down and are there ways to detect abnormal activity coming from an openvpn client?

• 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).

• VMware player suspends on screensaver

  - by Chad

  I have this problem with my VMWare player. When my host operating system either goes into screen saver or I lock the work station with Windows Key + L. VMWare player pauses or halts everything. So when i come back to the computer and there is a background task working inside the virtual machine it does not progress until i've actualy loged back on. Is there any way to stop this behaviour with VMWare player and keep it running in the background even when the screen saver or the work station is locked? Version of VMWare is: 3.0.0 build-203739

• How to login without entering username and password

  - by torbengb

  I'm a newbie running Ubuntu 9.10. I have two users (wife and me), and each user's screensaver is set to lock so that on wakeup, we get to choose which user's desktop to go to. However, Ubuntu requires a password, so this is pretty tedious. I'd like to switch users without entering any password. I know about this trick that works for the boot login, but it doesn't deal with multiple users. Is it possible to set empty passwords for users in Ubuntu, or skip the password in other ways? (I'm expecting real Linux users to suggest that passwordless users must not get any rights and there be an admin user with a strong password. Yes, you're right. But that's not what this question is about. Thanks.)

• 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?

• Remote desktop pressing Windows key randomly

  - by wikiti

  When I'm using remote desktop at work from one specific PC it has a quirk which is really quite irritating. I'll be typing away and suddenly the Windows key will be pressed, things start minimising, explorer launches, workstation gets locked (but it locks the remote workstation, so I have that wallpaper in the background, rather than the wallpaper from the local machine as I would expect). I've swapped keyboards, even though it didn't seem to be related to hardware and it made no difference. Done some internet digging and found someone saying it's related to using windows-l to lock the workstation. I've tried to stop myself using that shortcut to see if it helps and have failed miserably :D It's happening to at least one other user remote desktopping from the same machine to a different PC. Reinstalling isn't really an option (I don't admin the PC or I would have tried it, grr), although I could probably get it done if it would definitely resolve the problem. Any ideas?

• HP Pavillion dv6 laptop - 15 beeps on startup and a black screen?

  - by dunc

  Usual story - girlfriend's step-brother's laptop is broken. I don't know a huge amount about what occurred before it broke, but I do know the following: When you try to turn the laptop on, it beeps 15 times exactly. The screen remains black. The LED on the Caps Lock key flashes continuously. If left on, the laptop never boots - as far as I can see. If left on, on a stable surface with decent ventilation for a relatively short period of time, the laptop (below keyboard, but not where the RAM/HDD are) gets very hot. I've tried doing what most websites appear to recommend for similar problems, which is to disconnect AC and battery then hold the power button down for a minute before reconnecting the AC and trying to turn the laptop on - no difference. EDIT I've also tried re-seating the RAM, to no avail. Any ideas? Thanks in advance,

• df says disk is full, but it is not

  - by Chris

  On a virtualized server running Ubuntu 10.04, df reports the following: # df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 7.4G 7.0G 0 100% / none 498M 160K 498M 1% /dev none 500M 0 500M 0% /dev/shm none 500M 92K 500M 1% /var/run none 500M 0 500M 0% /var/lock none 500M 0 500M 0% /lib/init/rw /dev/sda3 917G 305G 566G 36% /home This is puzzling me for two reasons: 1.) df says that /dev/sda1, mounted at /, has a 7.4 gigabyte capacity, of which only 7.0 gigabytes are in use, yet it reports / being 100 percent full; and 2.) I can create files on / so it clearly does have space left. Possibly relevant is that the directory /www is a symbolic link to /home/www, which is on a different partition (/dev/sda3, mounted at /home). Can anyone offer suggestions on what might be going on here? The server appears to be working without issue, but I want to make sure there's not a problem with the partition table, file systems or something else which might result in implosion (or explosion) later.

• 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?

• 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.

• 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?

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.

• Is there a way to permanently remove highlighting from editable areas within a protected word docume

  - by CT

  Is there a way to permanently remove highlighting from editable areas within a protected word document? This is in relation to a previous question I had on locking portions of a Word Document located here: http://superuser.com/questions/143860/can-i-lock-or-make-uneditable-portions-of-a-word-document Using this solution, any editable area is highlighted. You can uncheck the Highlight editable area box within the Protect Document bar but if you save and reopen the area is highlighted again. The document is on a network drive. If another user were to open the document it would also be highlighted. Is there anyway to permanently turn this highlighting off so that when a user accesses the document from the network they do not see this highlighting? Using Word 2007.

• 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?

• Windows XP freezes completely

  - by Max

  Lately my Win XP SP3 started to make problems. From time to time it freezes completely. Which means that the system does not react to mouse and keyboard. Keyboard led indicators also do not react to CAPS-, SCROLL-, NUM- LOCK keys. The problem is that I don't understand what causes this behavior and it seems to happen randomly. System event log also does not contain any clues. I'm thinking this could be some driver/hardware problem, but I don't know which. Are there any tools that would help me figure out the cause of this problem? Does anybody have any clue how can I fix this?

• 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?

• icons in windows 7 taskbar moving by themselves

  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)'
