  • Practical way of keeping up-to-date backup servers?

    - by ftkg
    What is the approach generally used when you want to have backup physical servers? Currently I have a Linux server running a database, a samba share, a webapp and some scripts; and a Windows Server, running some third-party software. What I would like was to be able to have a ready backup server to enter in production in case of failure, but how to keep them up-to-date? I've seen some expensive solutions for Windows; for Linux I've wondered if I really have to build an array of scripts.

  • Failing RAM, or something else? [closed]

    - by Thanatos
    I have a IBM Thinkpad T43, currently running Windows XP. Programs were crashing, XP was blue-screen-of-deathing, (more than usual) - it was basically unusable, but I couldn't get any informative error out of XP. I booted Ubuntu off a thumbdrive, which made it to the desktop, but as soon as I started to try to do anything, X segfaulted, along with several other services, followed quickly by kernel warnings and a kernel panic. I'm currently running Memtest86+ on this machine, which is spitting out numerous errors. (16k over 3 passes, and counting) The failing areas are numerous, and look something like this: 0001055da4 - XX.X MB, etc. The addresses that fail seem to cluster around 0-20 MB, 250MB, and, more rarely, 750MB, 1000MB, and 1200MB. However, a lot (but not all) of the failing addresses that I've seen end in XXXXXXX?da4 where the ? is a 1 or a 5. The machine has two sticks of RAM, one 512MB, one 1024 MB, the 512MB mapped to the lower addresses, the 1024 MB stick following. Is this indeed RAM failure, or should I consider other things before purchasing more RAM?

  • APC UPS-5000 Power off remote servers

    - by Vishal
    Hi there, I have a UPS connected via the serial port to a server using PowerChute Business Edition. If a power outage occurs I would like this server to start shutting down all other servers within the network. Is there dedicated software to do this? I was thinking of creating a command file which runs a .bat file to run shut down commands to each server (using PSExec). I can set PowerChute to run this command file when a power failure occurs. Is there not anything APC provide which has this functionality and is more efficient than writing a .bat file to do this? Thanks,

  • BIND unstable with DLZ+MySQL on Ubuntu 9.10, any ideas?

    - by Chris
    My BIND server keeps dropping out and I can't work out why. Here is some info from the syslog that I think pertains to the failure(s): Apr 22 21:12:17 dnsdebug named[6613]: mysql driver unable to return result set for lookup query Apr 22 21:12:17 dnsdebug kernel: [285552.573949] type=1503 audit(1271963537.759:53): operation="open" pid=6618 parent=1 profile="/usr/sbin/named" requested_mask="::rw" denied_mask="::rw" fsuid=107 ouid=0 name="/dev/tty" Apr 22 21:12:17 dnsdebug named[6613]: mysql driver unable to return result set for lookup query Apr 22 21:13:17 dnsdebug named[6613]: last message repeated 7 times Any ideas? Mysql had a segfault sometimes, but that seems to be no longer an issue. It's the 64bit version of ubuntu too. Sometimes it will return records just fine, other times it appears to just randomly go down.

  • Error connecting to the application.

    - by ahmed
    Hi guys, let me explain you the current scenario. We have a asp.net application on framework 2 running on intranet(Windows 2003 Server and Sql Server 2000). Now we have a xp machine where we installed and configured IIS with a virtual directory pointing on the local Xp machine and this machine is connected to our intranet. We have copied the same application files of the server to this XP machine. But the thing is the connection string/database of the application is pointing towards the intranet server. The problem is when we try to run the application on the XP machine we get this error : An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) Is this query related or concerned with this site or stackoverflow ?

  • Nagios service active only when other service is failing

    - by Laimoncijus
    Is is possible to define service to be active only the times while other service is failing? Consider following example: 2 hosts available: HostA (primary) and HostB (backup). Nagios service, which monitors amount of active connections to the host: gives OK when amount of connections to host 0 gives FAILURE when amount of connections to host = 0 If setup nagios service to monitor both hosts: HostA and HostB - it will give me OK for HostA (while it is primary and all connections normally goes to it) and FAIL for HostB (while it is backup and will receive no connections while HostA is alive). Can I make the nagios service for HostB somehow depend on sevice of HostA and give no failures (or maybe be inactive) up to the moment the service of HostA starts failing?

  • Title: Better logging for cronjob output

    - by Stefan Lasiewski
    I am looking for a better way to log cronjobs. Most cronjobs tend to spam email or the console, get ignored, or create yet another logfile. In this case, I have a Nagios NSCA script which sends data to a central Nagios sever. This send_nsca script also prints a single status line to STDOUT, indicating success or failure. 0 * * * * root /usr/local/nagios/sbin/nsca_check_disk This emails the following message to root@localhost, which is then forwarded to my team of sysadmins. Spam. forwarded nsca_check_disk: 1 data packet(s) sent to host successfully. I'm looking for a log method which: Doesn't spam the messages to email or the console Don't create yet another krufty logfile which requires cleanup months or years later. Capture the log information somewhere, so it can be viewed later if desired. Works on most unixes Fits into an existing log infrastructure. Uses common syslog conventions like 'facility' Some of these are third party scripts, and don't always do logging internally.

  • Why is the screen resolution different between Windows 7 Ultimate and Enterprise editions?

    - by IDispose
    I installed Windows 7 Enterprise 64 bit edition on my Dell Precision M6400 with an nVidia Quadro Fx 2700M card and I see that even though the screen resolution is set to 1920 X 1200, its not the same as the Windows 7 Ultimate 64 bit installed on a second hard drive. Both OSes show that the screen resolution is set at 1920 X 1200 but Ultimate shows more pixels than Enterprise. I also reinstalled the display driver but in vain. Any ideas? TIA

  • "The network path was not found" - shortening the delay before Windows tries again

    - by Harry Johnston
    If I try to connect (over Windows file sharing) to a machine that has gone to sleep, I get a timeout followed by "The network path was not found". If I then wake the machine and try again, I still get "The network path was not found" because the connection failure has been cached. If I wait a while (about 30 seconds?) and then try again I can connect successfully. I understand this behaviour. My question is: is there any way to shorten the delay before I can try the connection again?

  • run a 2nd computer as an extra processor

    - by MMK
    I have a laptop with a busted l.c.d., but otherwise works fine with an external monitor. I was wondering if it is possible to connect it to my main pc as an extra processor(main pc is getting old, it's only single core processor) and if so how? I currently have them connected with a network cable so that I can access the laptop's hard drive but would like to use it to give my pc a bit more power. Both my pc and my laptop have 2 gb ram and are running windows vista sp2

  • Laptop crashes when connecting to external harddisk

    - by Gnot
    I recently had a problem with my laptop. when I booted up the machine, I would get a SMART failure error message and when I pressed F1 to continue, it would take a very long time to boot and it would come back to the same error message again. Thinking that my hard disk was dying, I bought a new hard disk and installed on my laptop and so now my laptop is alright. However I need to recover data from that old hard disk, so I bought an external hard disk case and placed the old hard disk onto the case and connected to my laptop with USB. The first few times when I connected, I could see the files from the old hard disk and managed to copy some files over although it took extremely long to transfer. But now whenever I connect to the old hard disk, after a few minutes, my laptop will crash and re-boot. Do you think my old hard disk is dead beyond repair? Or you can offer some help here? Any assistance would be appreciated!

  • Windows Media Player functionality for Ubuntu

    - by Xeoncross
    I have way to many music files to bother with setting up playlists. Especially since my files locations keeps changing as I move stuff around and swap between different computers, different mount points, and even different Operating Systems! So managing my media with any application is doomed to failure. However, since I still want to listen to the music I usually just select all the files I want to play at a time and then right-click to open them in a media player. Works great in windows media player and places all the tracks in a temp playlist on the sidebar. Fails in ubuntu using Rhythmbox since it doesn't understand "temp" playlists and just keeps adding files to your FULL listing of all sings on your whole computer. I have over three copies of some tracks now in my audio collection - and all of them are now invalid because the location of the files has changed. So what media player (for Ubuntu) works well with just temporary playlists and will allow me to open up my files without adding them to a collection?

  • Windows Recovery partition unusable after Ubuntu 12.04 install on Eee PC 1005P

    - by Crivat Camilar
    Installed Ubuntu 12.04 over the secondary (D:) partition with Grub2 handling multi-boot. Never accessed the 'Recovery' option in the boot menu until Windows7 Starter became unusable due to HDD failure (bad sectors on C:). Tried creating an USB recovery stick using the OEM's recovery application (F9) on hidden partition: all I got was a clean C:\ and an error telling me the recovery images cannot be found [R:\recovery\windowsre\ - or something very much like that] although everything is there (changed 'hidden' flag to check and copy contents). Nothing happens upon pressing F9, then Grub takes over giving the recovery option. The application starts but halts about 30s after initializing, very briefly displaying the error message above. I guess every time it goes through this it actually wipes C:\ but crashes immediately afterwards not being able to find what-ever .wim image files it needs. How to make it work?

  • Best practice guide to install to Program Files

    - by Cold T
    Have seen quite a few questions in Serverfault and Super User but none that specifically answers my question. We have an application that is being provided and installed by a third party company. They are charging market rate 'consultancy' fee to do this. They installed majority of the folders in the root of the C drive, to my shock. Are there any official Microsoft Best Practice guides out there to say applications should be installed in Program Files.

  • Removing folders from sycn parternships in Windows 7

    - by KE.
    A while back I set my computer up to sync folders on a shared network drive. I didn't choose my folders carefully and ended up with a huge amount of files to sync, which took forever. I would like to stop sync on those folders, then later select some smaller subfolders to sync. I believe this means I first must delete the existing sync partnerships, but there is no "Delete" option when I list them in Sync Center. How can I delete existing sync partnerships?

  • Replacing hard drives in a LaCie 2big Network

    - by Jason
    I have a LaCie 2big Network that currently has 2 500GB drives in it (mirror). I'd like to upgrade the drives to 1TB each using something like this I know that Lacie sells a 1TB drive designed for the 2big Network but it would seem to me that these drives are standard drives with the Lacie holder included. Do I need to use their drives or can I get my own? (Their customer support pushes me towards their drives) I'm assuming the device can format the drives for me when I add them in.
