• High system cpu load (%sys), system locks

  - by Mark

  For the last two weeks we are having intermittent severe spikes in system cpu usage (shown as %sys), which last for maybe half a minute, locking most processes, including ssh. I've been trying to figure this out, but atop doesn't show anything relevant (system usage for processes it shows is insignificant), spikes are intermittent and I could not reproduce the spike using any workload for the web application this webserver hosts. If you have any ideas on how to debug high %sys and (sometimes) %si CPU usage, please share them. System specs (don't know if any of this is relevant): Dedicated server, CentOS 6, core i7 950, consistent 4 to 8 GB RAM free at any time, hard drives are in RAID-1. Additional info: dmesg output doesn't change between spikes /var/log/messages doesn't change between spikes Here is cat /proc/vmstat Here is output of mpstat 1 during a typical spike Add 07.11.11: looks like simple reboot restored system state, and we might never know what caused the disturbance in first place.

• Thunderbird "Folders" and "Inbox" font size

  - by bo gusman

  Graphical programs are such a pain sometimes. I am of an age where 1024x768 is the highest resolution that I can see. I had set my Windows 7 system fonts to be 125% - that helps a lot - but it screws up the tool bars on many other programs so I've reverted to 100% and it's now too hard to read in many cases. Most browsers will let you easily scale text font size as will the "message" window of Thunderbird (aside from setting the default font size for reading messages to 24 point, CTRL + + works wonders). However, I cannot seem to find a way to set the font size for the other panes - the Folders pane and the inbox pane. Is there some undocumented way to do that?

• Fusion 3, Windows 7, frequent blue screens

  - by kenny6127

  Is anyone else seeing this problem? A solution would be great (hey, it's Windows, it's gonna blue screen, just gotta deal with it), but it's also nice to know if it's something specific to my configuration, or if a lot of folks are having the same issue. Here's the details: * MacBook Pro 15" unibody, 4 GB, 2.4 GHz, 10.5.8 * Fusion 3.0.1 * Windows 7 Pro, 32-bit (clean install, not migrated from Boot Camp or anything) Blue screens happen nearly every time the MBP cover is closed for a short period of time (< 3 minutes). If the cover is closed for a half hour or longer, the VM is fine. I'm guessing it might be related to sleep, but that's hard to tell, and the Windows crash dump logs are pretty useless. Thanks!

• Running Ubuntu off a USB drive?

  - by Solignis

  I was wondering if a USB 2.0 Thumb drive has enough bandwidth to act as a primary system drive in an Ubuntu Linux server. More specifically an SAN server. I am running an iSCSI target, ZFS and NFS-kernel-server, BIND9 (Slave), and Openldap (Slave). I was thinking of resorting to a thumb drive because my new motherboard only has 4 SATA ports and I have 5 disks. 4 (ZFS Pool) 1 (System). And unless I get an expansion card there is no way to get more SATA ports. This "server" leans more twords a home server. I use in my lab with my VMware server. It provides storage, or atleast it did until it died. Would it still be better to go with the SATA hard disk?

• Is it safe to remove Per user queued Windows Error Reporting?

  - by Rewinder

  I was cleaning up my laptop hard-disk, running Windows 7, and as part of the process I ran the Disk Cleanup utility. To my surprise I saw 2 items in the list that were quite large (both ~300MB). Per user queued Windows Error Reporting System queued Windows Error Reporting I guess I had never noticed these, because they were never that big. So, what are these items? Any particular reason why they became so large all of a sudden? And finally, is it safe to remove them?

• ASUS N550 laptop not charging on ubuntu after updating kernel

  - by OBY Trance

  I'm using Ubuntu 13.10 on a pretty new ASUS N550jv laptop. When I was using kernel linux-image-3.11.0-11 everything was quite well (kinda..), however, when I updated the kernel using the automatic update, the kernels which were released afterwards (12+) were faulty on my machine, and caused the battery not to be charged and only stay at their current charging level (even when the machine was off!) The only fix I had was to roll-back to the '..11' version (on boot screen - advanced options), and hard-reboot (AC cord disconnected and reconnected) but now version 14 was released and "pushed away" the good old version 11. How can I fix that?? Please help me...

• Turning a running Linux system into a KVM instance on another machine

  - by Charles

  I have two physical machines that I wish to virtualize. I can not (physically) plug the hard drives from either machine into the new machine that will act as their VM host, so I think that copying the entire structure of the system over using dd is out of the question. How can I best go about migrating these machines from their hardware to the KVM environment? I've set up empty, unformatted LVM logical volumes to host their filesystems, with the understanding that giving the VMs a real partition to work with achieves higher performance than sticking an image on the filesystem. Would I be better off creating new OS installs and rsyncing the differences over? FWIW, the two machines to be VM'd are running CentOS 5, and the host machine is running Ubuntu Server 10.04 for no particularly important reason. I doubt this matters too much, as it's still going to be KVM and libvert that matter.

• In Linux, is it possible to get a listing of drives' disk space usage that also shows volume labels?

  - by DavidH

  I know about df, of course, but df does not output volume labels. I have 5 USB hard drives plugged into my NAS box, and would love to know which is which. Current df output: Filesystem Size Used Avail Use% Mounted on /dev/sda1 27G 2.2G 24G 9% / none 56M 476K 55M 1% /dev none 60M 0 60M 0% /dev/shm none 60M 332K 59M 1% /var/run none 60M 0 60M 0% /var/lock none 60M 0 60M 0% /lib/init/rw /dev/sde1 150G 102G 48G 68% /media/usb0 /dev/sdb1 299G 196G 103G 66% /media/usb1 /dev/sdc1 233G 183G 51G 79% /media/usb2 /dev/sdd1 233G 209G 25G 90% /media/usb3 /dev/sdf1 150G 101G 49G 68% /media/usb4

• VMware Workstation 7 build 203739 - Capture Movie Mouse Pointer Not Visible

  - by BMIVM

  Hi, I have noticed that whenever I create a Capture Movie, the movie is fine but the mouse pointer is not visible at all. The clicks are on buttons file menus are executed but is hard for a viewer of the capturre movie session to follow the recording smoothly. This was not a problem in previous versions of WorkStation. Is this a bug or is there a setting I can set to see the mouse pointer? Note: VM Tools are installed, Host is Vista Ultimate Edtion SP1, x64 and the guest is a Win XP SP2. Thanks in advance for your help.

• Restore wubi install after changing master drive

  - by Johnny

  Recently I got a 160G drive to install other Unix distributions and learn to use them for the sake of my current job. However I've got only 2 drive connectors free (on the primary channel). Therefore I've decided to remove an 80G hard drive which has the MBR and the main Windows bootloader. My problem in particular is that I've got another 250G drive which has a Wubi installation of Ubuntu 10.04 (Lucid Lynx), which I want to preserve on the bootloader that's going to be running for all the other OSes (potentially Grub). How would I do that? Since Wubi is actually sort of windows reliant, as far as I've learned so far.

• HTTPS load balancing based on some component of the URL

  - by user38118

  We have an existing application that we wish to split across multiple servers (for example: 1000 users total, 100 users split across 10 servers). Ideally, we'd like to be able relay the HTTPS requests to a particular server based on some component of the URL. For example: Users 1 through 100 go to http://server1.domain.com/ Users 2 through 200 go to http://server2.domain.com/ etc. etc. etc. Where the incoming requests look like this: https://secure.domain.com/user/{integer user # goes here}/path/to/file Does anyone know of an easy way to do this? Pound looks promising... but it doesn't look like it supports routing based on URL like this. Even better would be if it didn't need to be hard-coded- The load balancer could make a separate HTTP request to another server to ask "Hey, what server should I relay to for a request to URL {the URL that was requested goes here}?" and relay to the hostname returned in the HTTP response.

• Unix like console for Windows (GIT)

  - by olo

  Currently I am using windows version git software for git, I found it is really hard to copy and paste in the console, and the mouse middle key is not supported. I used to putty SSH way to linux box then do things in putty, but at the moment I only have windows. so does anyone know some tools enable end-users have UNIX console ? Mouse middle key and highlight supported is essential. Thanks in advance for any advices. Update: Downloaded virtualbox then install a copy of Linux..then samba... seems making things complicated but handy.

• Provide credentials to process in a safe manner

  - by Erik Aigner

  On system startup I need to launch a process which requires credentials for other services (database etc.) to interact. I obviously don't want to store those on disk for security reasons. I'm trying to think of a way to provide those credentials to the process on launch - and on launch only. After that they should be only available to the process. Is this possible somehow? The bottom line is to make it as hard as possible for an intruder to get to those credentials.

• Number of malicious attacks defended/done on the average user daily [closed]

  - by DalexL

  As a web hoster, it is very easy to notice the large amounts of exploit/abuse attempts done on my servers. Out of curiosity, how often are these attempts done on the average user? I'm assuming almost all of them are prevented just by simple security protocols in place by their browsers, local network, etc. How many attempts, on average, are committed against a single user daily through any method? (email, internet, downloads, etc.)? If known, what percentage of these things are blocked by the average users security? I tried googling but I was having a hard time getting the right search terms together.

• Windows Server 2008 Enterprise. Incorrect password on screensaver

  - by LarsErikP

  First some software details: Thin client: Wyse C10LE Citrix - Windows Terminal Services - Windows Server 2008 Enterprise desktop I have a user with a very strange problem. When he locks his screen with Win+L, Windows claims he's entering wrong password when he tries to log back in. The only solution is to hard reboot the WYSE, and log back in. This reboot doesn't kill his Windows session. I've checked for errors in keyboard settings (wrong layout etc), nothing found. I suspect errors in his profile/errors in AD. No other users in the domain has this problem. EDIT: Sorry, it's NOT Win R2. Plain Windows Sever 2008

• Data unaccessible from WHS drive

  - by Eakraly

  Hi all, I had a Windows Home server machine that crashed. Before doing anything I decided to get data out of it. So I took the hard drive and connected it to Windows7 pc. What I get is that I cannot access almost any file! I do see directory structure, I can open small files like .txt and .ini but bigger files like .iso and video - no go. Same goes for Ubuntu and OS X - I can see files and even copy them - but they are corrupted. Any ideas for what the problem is?

• How do I get my 192.168.* Linux server accessible via http://hostname/?

  - by rfrankel

  (Sorry if this question isn't worded well and/or is duplicate. I'm not a networking guy and I'm probably not using the right terms...this also makes it hard to see if this has already been answered.) I'm running a CentOS server in VirtualBox, Windows host, and I can see access Apache-hosted pages at http://192.168.1.109/ from machines on my LAN. But what I'd like is for people to be able to type http://hostname/ ...both because it's easier and primarily because I'm not sure that local IP is static. I'm not really sure how to proceed - could someone point me in the right direction? Thanks.

• VMware snapshost issue

  - by Calcgod

  I am using VMware Fusion 2.0 on a Macbook Pro. I have allocated 20GB to a windows partition within VMware, and now wish to expand that. When I go to the settings for the hard drive it tells me: "These settings cannot be changed while the virtual machine has a snapshot. To make changes, first delete all snapshots." When I go to the snapshots settings nothing appears there besides the current state thumbnail. Is there a way to remove these "invicible" snapshots??

• Best ways to move a server room and 80 desktops to a new building

  - by Marko

  Need to plan the best way to physically move a server room (12 IBM x3400 towers) and all associated networking equipment to a new building. Everything is going, comms (80 strong call centre operation), desktops(80-90) the whole lot and has to be done efficiently over a weekend. What I cant seem to find are the best ways to move equipment, i.e is it best to remove hard drives and pack them separetely, do I pack the chassis' with foam and/or surround them in bubble wrap? Are there specific products designed to move computer equipment and where would I find these. The internet has failed me so far, please help

• Recovering data from a corrupted disk

  - by r_honey

  I use an external harddisk to backup my data (it had 3 partitions). Last week when I plugged it in, the OS (Win 7) hung up and I had to force re-boot the machine. When I turned it back on, the system just did not detect the hard-disk. It was last Sunday and I had to give up after sometime. Now I return back next Sunday (today) and when I plug it back-in to the machine, the OS detects the disk as well as all the 3 partitions on it. But it says all 3 are unformatted and I cant access any of them. Is there any way to recover data from the 3 partitions (I tried PC File Recovery and Recuva from PiriForm but neither detected these partitions).

• RAID striping on a desktop machine

  - by Blazemore

  I currently have a 120Gib SSD which is pretty fast for things like game loading times and video editing. However, I was wondering about getting another identical drive and hooking it up with a striping RAID array in hardware (I boot multiple operating systems). This would have the dual benefits of providing a larger logical drive, while also providing greater performance. However, I have a few questions: What kind of performance increase can I expect to see with a pair of good quality SSDs? How expensive is a quality desktop RAID controller? Will the controller present the OS with a single logical drive? Does this mean I can still partition it and multi-boot? Basically, can I treat the RAID controller as "a hard drive" at the OS level?

• No wireless adapter in msi u200

  - by Mino Marimat

  I have a MSi u200, and the weird thing was that I was using this normally before, then after a few minutes all of a sudden it couldn't find the wifi signal from my house. I did some troubleshooting and a bit of search in the control panel, and it seems like my hardware is missing. :( I can't even turn on the wireless light using Fn+F8, so my suspicions about the missing hardware strengthened. I tried searching for DIY fixes, but I found out that the wireless card is actually built-in deeper, unlike the RAM cards and the hard drive where you can either replace or add more cards. What do I do?? As of the moment, I can get connected to my wifi here at home using a wireless adapter via usb, and it's working. So my guess about the hardware problem seems correct. HELP!!! Thanks!

  Hi everyone, This is my question. I have one Xen server with 8 CPU's and 6 virtual machine running, each virtual hard disk are running in diferent physical hardisk. Everything worked fine but sometimes one virtual machine get almost whole CPU, if the Domain-0 is 90% that is normal, the virtual machine is 500% usage of CPU. I have improved that it is not depends who are working with the VM even when nobody are working with the server this still happens. I dont know what happen.
