Script: Bash: Changing a Config File on Multiple SSH Servers
Summary: How to change a config file on multiple esx servers using ssh.

I want to change a config file on multiple esx servers to solve the problem that after updating them to ESX version 4.1 I can't copy/paste into the VM console anymore. The solution is to add two lines to the /etc/vmware.config file. But I don't want to log on to each host and make the change. And ssh doesn't allow for passwordless logons unless you use key authentication. In this case I didn't want to do key authentication so created and used this script to solve my problem.

PowerShell: Create an Excel report with Server Status and Compliancy
Summary: This script is what I use to make one large inventory of all or VMs and physical objects in Active Directory. It creates a nice view in Excel on topics that are important. It allows for vCenter and Active Directory to document itself using the notes and description fields. Please notice so that if an object lives in both vCenter and Active Directory the virtual objects takes precedence.
