Disable host check/ping in nagios

Wednesday, January 6th, 2010

problem I want to validate services of a host, though the host is not pingable (e.g. public www server)

solution For the host definition make sure no 'check_command check-host-alive' line is there (including lines inherited from templates). For nagios 3.2 / gentoo I changed my template for the host to 'generic-host' and added 'max_check_attempts 10' and 'contact_groups admins'.

VPN connected machine, Active Directory and DNS

environment: AD Server in Sub-Net A, Client in Sub-Net B

problem: Client can't find logon server

solution: I configured 2 dns server. The first one was the remote AD server, the second one a public one.
For some reason Windows favored the public one and could not resolve the logon server. Removing the public one helped.

Recovering ICH9R RAID to IDE switch after BIOS upgrade

Thursday, September 11th, 2008

cause two SATA disks in RAID-1 (mirror) configuration using ICH9R on-board controller. after bios upgrade of my Abit IP35 the bios settings got reset and the OS (Windows Server 2008) booted with SATA onboard controller mode IDE instead of RAID.
implications the mirror got broken, but Windows actually booted AND changed the boot record.
errors I changed the mode back to RAID (*BAD IDEA*). Started the Intel Bios and re-joined the mirror (*BAD IDEA^2*). Now Windows didn't start anymore (Boot loader started, but Winload.exe was missing).
why *BAD IDEA*? The Intel controller chose the wrong disc. So my changes since Bios upgrade and rebuilding the mirror were lost.
solution Windows RE (Recovery Environment) helped out. Starting with the Windows Server 2008 installation disc, I was able to load the drivers, but didn't see any operating system.
Start the command prompt and execute diskpart.

Using "list disk" I saw the RAID volume, but this was marked as "foreign" (maybe because the partition/volume was part of a Windows Mirror as well). You need to use "import". Afterwards the disks are visible.

Go back to the dialog were you started the command prompt and close the window. This returns you to the previous dialg (no back button :( !!!). No the "Repair Mode" sees the partition and those it's job.

I'm running Hyper-V on that server and after recovery all the Hyper-V services were running, but no VM started.

Use "bcdedit /set hypervisorlaunchtype auto" from here.

Shuttle SX38P2 Pro *addons*

Shuttle SX38P2 Pro the ultimate laptop replacement

First of all the carrying bag from shuttle suck for this kind of machine - way too heavy.
So I checked various bag shops - either too big, too expensive or too ugly!
So finally I found something at IKEA! I'll provide pcitures later. It fits perfectly and even has space for my keyboard.

Right now I suffer with installing Windows XP without a floppy. I could not do it. I think I failed because the 2 disks are configured as RAID 0.

For dual boot config menu changes here

I finally installed Windows Server 2008 x86 to get VTune 9.0 update 7 to run.
