# A simple PowerShell script for retrieving the RAID status of volumes with help of diskpart.
# The nicer solution would be using WMI (which does not contain the RAID status in the Status field of Win32_DiskDrive, Win32_LogicalDisk or Win32_Volume for unknown reason)
# or using the new PowerShell API introduced with Windows 8 (wrong target system as our customer uses a Windows 7 architecture).
# 
# diskpart requires administrative privileges so this script must be executed under an administrative account if it is executed standalone.
# check_mk has this privileges and therefore this script must only be copied to your check_mk/plugins directory and you are done.

UEFI PXE Installation of RHEL6.4

For some reason, starting a PXE boot installation of RHEL6.4 on UEFI systems is poorly documented. Simultaneously, the process is not terribly verbose when it fails. Here's what I had to do to get this to work.

We going to use Cobbler to take care of a lot of the gruntwork (TFTP, DHCP, etc). It's entirely possible to do it without Cobbler, but even accounting for its warts it will make you more

SSH agent forwarding and screen

When connecting to a remote server via SSH it is often convenient to use SSH agent forwarding so that you don't need a separate keypair on that server for connecting to further servers.

This is enabled by adding the

ForwardAgent yes

option to any of your Host entries in ~/.ssh/config (or alternatively with the -A option). Don't set this option in a wildcard Host * section since any user on the remote server that can bypass file permissions can now als use keys loaded in your SSH agent. So only use this with hosts you trust.
