• Decompressing Files on an NTFS Volume from Linux

  - by amphetamachine

  I recently did something stupid on my dual-boot laptop, where I compressed the entire volume to make room for a Linux partition. For some reason, Windows let me compress C:\ntldr. Now I need to get it uncompressed in order for Windows to boot. Here are some of the operating restrictions I have: I do not have access to the BIOS. I cannot boot from CD/USB/floppy. (I installed Linux through PXE) It does not have network access. Is there were some way to specify that the ntfs-3g driver shouldn't compress files even if it thinks it should (if the directory is compressed) when mounting the volume? Or, is there a way to modify the attributes of a directory using ntfstools?

• How to properly use windows xp mode

  - by user23950

  I just want to know how could I access the applications installed on xp mode in windows 7. I just installed the application in the default location in xp mode which is c:\program files Do I have to install it on the drive where windows 7 is installed so that I could access it quickly? Because I still have to wait for about 2-4 minutes just to open up a word document(ms office installed in xp mode) that is saved in my desktop in my physical machine. Please help. Details: 2Gb of Ram Pentium Dual Core processor 250GB of HDD

• Where can I find logs for SFTP?

  - by Jake

  I'm trying to set up sftp-server but the client is getting an error, Connection closed by server with exitcode 1 /var/log/auth.log (below) doesn't help much, how can I find out what the error is? I'm running Ubuntu 10.04.1 LTS sshd[27236]: Accepted password for theuser from (my ip) port 13547 ssh2 sshd[27236]: pam_unix(sshd:session): session opened for user theuser by (uid=0) sshd[27300]: subsystem request for sftp sshd[27236]: pam_unix(sshd:session): session closed for user theuser Update: I've been prodding this for a while now, I've got the sftp command on another server giving me a more useful error. Request for subsystem 'sftp' failed on channel 0 Couldn't read packet: Connection reset by peer Everything I've found on the net suggests this id a problem with sftp-server but when I remove the chroot from sshd config I can access the system. I assume this means sftp-server is accessible and set up correctly.

• Better to develop Ruby project on server or buy a faster desktop computer? B/c laptop too slow.

  - by user33184

  I have a Linux laptop (Vostro V13) running a Celeron M chip. This is a fine laptop, but running unit tests especially for Rails applications is slow. I want a faster development environment but I don't want to spend too much money. So the choice I have is between $390 for a Linux desktop machine with a Pentium Dual Core Processor E5400 and just paying between $30 and $40 a month to Linode and trying to do development remotely on that server. Can anyone with experience developing server applications using both methods offer any advice?

• Add 802.11n to existing 802.11g environment

  - by Andrew Robinson

  I have a small home network that is currently running 802.11g. Two computers that are capable of 802.11n and two devices (a BlackBerry and a Skype phone) that are limited to 802.11g. I have a few neighbors running 802.11g but their signals are very weak. How big an impact will the two G devices have on N speeds? Will they pull the whole network back down to G? These two devices are hardly ever used where as the other N devices are heavily used. If I add an N router to the network (instead of replacing the G) and set my existing G router to use channel 1 with 20MHz bandwidth and then set the N router to use 6 & 11 for 40MHz will I eliminate the overlap and allow for full speed on both networks?

• Move virtual machine hard disk to a separate physical hard disk for better performance?

  - by joeeoj

  I have a dual-core machine with the host OS and many guest virtual OSs. Although I have 8GB of RAM, I notice a slowdown when I turn some virtual machine on (and it takes only 1GB RAM). I was told that I should move virtual machine hard disk file to a separate (another) physical hard drive in my PC to get better performance. This way the head of the hard disk would not have to jump from the virtual OS to the host OS as each hard drive would have its own head to deal with the OS: hard drive 1 head for host OS and hard drive 2 head for guest OS. Is this true? Should I get another hard disk only for virtual machine hard disk files?

• Location Services are always disabled in Mac OS X Lion

  - by rplusg

  A simple location services program was working fine on my machine and suddenly stopped working. Upon further exploring the problem, I realized that some process has disabled location services in System Preferences » Security & Privacy » Privacy. I checked Enable Location Services, but again it got disabled automatically. After some research I found that it's not just my program, even built-in system functions are also failing because of this problem for example System Preferences » Date & Time » Time Zone failed to get the current location. Every time I check Enable Location Services, I see the following error in the console logs: 16/10/12 11:23:15.636 AM [0x0-0x42042].com.apple.systempreferences: ERROR,Time,372059595.636,Function,"CLInternalSetLocationServicesEnabled",CLInternalSetLocationServicesEnabled failed 16/10/12 11:23:15.638 AM [0x0-0x42042].com.apple.systempreferences: STACK,Time,372059595.636,1 CoreLocation 0x00007fff8f9957be CLInternalSetLocationServicesEnabled + 110 Notes: WiFi is on I didn't install iOS Simulator I use Xcode Version 4.5 (4G182) I use Boot Camp and made my MacBook Pro dual boot (Mac OS X Lion and Windows 7) I do only Mac development but not iOS

• GRUB Error after Deleting Linux Partition

  - by Nironan12

  I was dual-booting with Windows 7 and Windows Vista each taking up half of my hard drive. In Windows 7 I used Easeus Partition Manager to shrink my Windows 7 volume 8GB. On the unallocated space, I installed Linux Mint 8 RC1. After a little bit of playing around with it, I booted in Windows 7, used EPM again and deleted the 8GB Linux partition. I then extended Windows 7 on the 8GB. After restarting my computer, all I get is a black screen and this: GRUB loading. error: no such partition grub rescue> I do not have a Windows 7 disk nor does my computer come with Startup Repair. What do I do?

• strange behaviour - dhclient needs to be run twice in order to connect to wireless

  - by splicer

  I am trying to connect my to my wlan without the use of NetworkManager. I run the following commands after boot: iwconfig wlan0 enc <WEP passwd> mode managed essid <name> channel 6 ifconfig wlan0 up dhclient wlan0 At this point, dhclient stalls for ages (perhaps 2 minutes), then it returns with PING 192.168.1.254 (192.168.1.254) from 192.168.1.65 wlan0: 56(84) bytes of data. --- 192.168.1.254 ping statistics --- 3 packets transmitted, 0 received, +3 errors, 100% packet loss, time 3000ms pipe 3 .. The strange thing is that when I run pkill dhclient; dhclient wlan0 right after this, it connects in about <3 seconds. Any idea what could be the cause of this problem? Edit: oh, and I did try using the -timeout flag on dhclient but that didn't seem to make any difference (it still stalled for ages).

• How to view status of software RAID 1 resynching?

  - by tputkonen

  I have two 500 GB disks and yesterday I mirrored first drive to the second one using software RAID 1. PC has now been on for 30 hours. Both disks say "Resynching", but there is no progress indicator. In addition, there is a small yellow exclamation mark on both disks. My questions are: How long could the synch take for 500 GB drive with about 150 GB of data? PC has 4 GBs of RAM and AMD dual core 4000+ Is there a way to monitor status of the synching? How can I check what the exclamation mark means?

• Windows - Force Wi-Fi to N mode

  - by Frederick Marcoux

  I bought a month ago the D-Link DWA-160 Xtreme N Dual Band USB Adapter and I wonder about the speed. I have a 60Mbps but the speed is never above 300Kbps when I browse Internet or download something. Even from Microsoft or Apple (the fastest server I found). Now on Windows 8, we can see the Wi-Fi stats in Task Manager, there they are: Notice the red rectangle. The signal is 3/5 and I'm about 5 meters far from my router. An Apple Time-Capsule. Also, the connection type is 802.11g, I want N. I made this config in my Device Properties: Does anyone figured out to force the 802.11n in Windows? (Windows 8 preferably)

• Limit disk I/O one program creates?

  - by Posipiet

  Hardware: one virtualization server. Dual Nehalem, 24GB RAM, 2 TB mirrored HD. Software: Debian, KVM, virt-manager on the server with several virtual machines that use Linux too. 2 TB Disk is a big LVM, each VM gets a logical volume and makes its own partitions in that. Problem: One of the programs that runs on one of the VMs creates huge disk load. This never was an issue, because the program never ran on such a powerful hardware. Now the CPUs are fast, and lots of I/O is the result. We cant do much against that at the moment, because the tool is a black box. On the other hand, the speedy computation is welcome. The program creates about 5 GB of temp files which get overwritten during the next iteration. Question: How can we limit the disk I/O for the process?

• Why did my laptop turn off?

  - by darenw

  Normally I can slip my running laptop into a backpack, go somewhere, and if it's no more than about half an hour later, it'll still be running. At the destination I plug in the AC power unit and all is well. I run it off of the AC unit before and after the trip, have the screen at less than full backlight brightness, and don't have any peripherals that burn power. Sometimes the wireless switch accidentally slides in the backpack, and that causes extra power to be used and the laptop dies before I reach the destination. Sad, but so be it. But sometimes the wireless switch is off, I've reached the destination in less than 30 minutes (typically 10-20 min), and I know the battery was fully charged, yet the machine is off. Is there a way to determine, after the fact, why the machine shut itself off? I'm running Linux on a fairly powerful Gateway with 4GB RAM, fancy nvidia graphics, dual core cpu, chosen more for number crunching power than battery life, but should last easily for half an hour if not an hour.

• Dell docking station / Windows 7 not detecting HannsG JC199D via DVI

  - by user27150

  I have a laptop running Win7 that I use with a Dell docking station. I'd used it with XP for a couple years running dual monitors from the docking station, one from the VGA and one from the DVI. After upgrading to Win7, the monitor that's on the DVI out is not detected, using "rigorous detection" or otherwise. I've switched the cables to verify that it's not the monitor at fault-- but I can't find any info on why the monitor wouldn't be detected. I've got the latest and greatest Nvidia drivers installed (at least, as far as Windows update is aware). Leaving the laptop lid partly open does allow Windows to detect the laptop's native screen as well as the VGA monitor, but never the DVI. The monitors are HannsG JC199Ds. Any ideas? Thanks!

• ATI Radeon 5850 I cant seem to get 3 monitors up at the same time. 2 Monitors and a HDTV but still.

  - by Jan

  Ive just bought the top end ATI Radeon card with 2 normal monitor ports and a HDMI. The idea was to continue using my dual screen setup as always and to use the last plug, the HDMI on my TV. I got a new 52 inch HD TV with all the necessary bits. This should work fine. But.. in Display Properties I still get only my 2 monitors up as options. Not the Digital TV. When I unplug 1 monitor and restart the computer, I get the TV and the other monitor. But never all 3 at the same time. Why is this ? Where can I go to tell it that I need all 3 screens at the same time. Also I get a message saying my gfx card also gives sound through the HDMI cable.. But the TV tells me its recieving a sound format that it does not understand. Any ideas on that too while were at it ?

• Triple Boot - With storage partition

  - by art

  I'm new to the multi-boot world, as i used to rely on virtualizing for running linux. Recently i moved to Dual booting Windows 7 and Ubuntu, with a storage partition for all my files where both operating systems could access them. Is it possible, to have 1 partition for 7, another for XP, another for Ubuntu, and a separate partition where the OS's can access my files? so 4 partitions on my hdd. and if there's a better way to go about this (or if its not possible), please let me know! thanks

• Will Software RAID And iSCSI Work For A SAN

  - by Justin

  I am looking for a SAN solution, but can't afford even entry level solutions. Basically, the SAN is for development and a proof of concept product. The performance doesn't have to be amazing, but needs to be functional. My buddy says we should just setup sotware RAID and software iSCSI in Linux. Essentially I have a spare server with dual Xeon processors, 4GB of memory, and (2) 500GB 7200RPM drives. It's a bit old but working. I am sure there is reason people don't do software RAID and iSCSI, but will performance be usable? Thinking of configuring the drives in RAID 0 (for performance).

• Strange noise from my laptop when it is closed

  - by gotqn

  I am fan of powerfull PCs with huge wide screen monitors but I have bought an laptop as gift to my parents. This is the description: "second-handed" lenovo (and there is a sign "ThinkPad" Intel Core Duo CPU T6570 2.10 GHz 64 bits Windows 7 Ultimate and the issue is that when the laptop is turn on and then closed, after a interval of time (I am not sure how much exactly but I believe it is several hours) a strange noise come from the laptop. The noise is something like a "start-up" noise of old computers. I first thought this is some hardware issue but everything seems to work fine. Has anyone an idea what can cause this type of noise or a what can I do in order to track the problem down? I am not sure if this is a important thing, but the laptop is always connected to the power. Note: I have just noticed that the sound is generated again when the laptop is closed and then opened. Note: This is link to the audio - http://yourlisten.com/channel/content/16934332/WindowsStrangeNoise

• OS X clients ignoring Windows print server permissions

  - by Ilumiari

  I'm in the process of testing a Windows Server 2008 R2 print server for a mixed OS X/Windows environment. Any security permissions (AD groups) I set for the printers on the print server are not honoured by the OS X clients. Only if I remove absolutely all permissions for a given printer will an OS X client not print to that printer. The Windows clients honour the permissions as expected. The PrintService log doesn't record any activity when an unprivileged Windows client attempts to print, and records a typical print job when an unprivileged OS X client attempts to print. Has anyone encountered this problem before and have a fix? With 600-700 clients, a number of which are dual-booting, restricting by IP address is not viable. EDIT: The jobs are definitely going through the print server, they show up in the logs with their AD credentials.

• Help me understand how Xen vCPU/CPU works

  - by luckytaxi

  Say I have a Dual-Core server, that's 4 cores w/ two physical processors. I read numerous articles that states the dom0 should get one physical core to itself. By core, does that mean a single CPU core or one of the 4 logical cores? Ideally I would like to dedicate a single CPU core (2 logical) to the dom0. Then I would give the other CPU split between the 3 VMs. I've seen examples where ppl would assign more than the available number of cores to a VM and I don't know what good that would do. I mean, why would I want to assign 4 vCPU to a single VM when I only have 2 available (if my math is correct)? I assume I only have 2 available from the one core as I've given dom0 a CPU to itself.

• What would be better in my case - apache, nginx or lighttpd ?

  - by The Devil

  Hey everybody, I'm writing a php site that's expected to get about 200-300 concurrent users browsing it. When initializing the application will load about 30 php classes, some 10 maybe 15 images and a couple of css files. So my question is what else can I do (except optimizing my code and using apc/eaccelerator for php) to get as close as possible to those numbers of concurrent users ? Currently we haven't chosen a server for the site to be hosted on but most probably it'll be a VPS Dual core + 2 or maybe 4gb ram. Is it possible for such a server to handle that load ? Also how could I test it myself and be sure that it'll be able to handle it ? Thanks in advance, Me

• Cannot ssh anymore into FreeBSD 7.2 home server

  - by Gabi

  Somehow sshd stopped running and no amount of start, restart or onestart will make it go again. I normally ssh into it from a dual-boot laptop computer that shows up on the network as gabi-buntu when running Ubuntu Karmic, and as gabi-pc when running Windows XP Pro. Neither my Putty connection nor the Linux terminal can establish a ssh link anymore. Upon rebooting the server, I am greeted with "/etc/rc: WARNING: run_rc_command: cannot run /usr/sbin/sshd". In addition, a message will appear saying things like rpc.statd: failed to contact host gabi-buntu RPC: port mapper failure RPC: timed out Everything else works fine. The FreeBSD 7.2 box runs a print server, a Samba server, and an Apache server for the home wiki, via https. It also serves up NFS shares for Linux clients. Any suggestions? Thank you, Gabi Huiber

• Keyboard causing freezes

  - by fluteflute

  My problem started on Windows XP: a computer (that was working fine for many years) had a problem, that I can't quite remember (may have been to do with the startup process) - but I solved it by swapping the keyboard with one on another machine. Now for several years the problematic keyboard has been working fine - on my main machine that runs Ubuntu. I also dual boot Windows XP - and have had no problems on either OS. However I recently installed Ubuntu 11.04 Natty (pre-alpha) and found that any keyboard press causes freezes. (All still works fine on Ubuntu 10.10 and 10.04 and Windows XP) Just wondering why I might be experiencing this? Seems strange to me that's its not consistent.

• Linear Performance Scalability with HP San Solutions

  - by Berzemus

  Hi all, I need a San Solution with linear scalability in size as well as in performance. From what I know, with a Modular Smart Array solution such as the P2000/MSA-class solutions from HP, even with a dual controller initial node, I can only increase the size of it, as added nodes come controller-less, so overall performance tends to decrease. On the other hand, the P4000 (lefthand) family of solutions has each of it's nodes have it's own controller, and so when a node is added, storage capacity as well as performance increase. Am I right in all that I say, and is the P4000 the only solution, or have I forgotten something ?
