Echo.. echo.. [VMware techie stuff]

I hate it when the virtual machine especially those you've deployed linux with, echoes every single character you input twice on the console. All the while I had thought you can get this fixed by installing the VMware Tools. I knew it was partly due to the network latency. But apparently there is a fix or workaround on VMware's KB click here -> http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=196


All you need to do is on the vSphere client
  • Power off the virtual machine
  • Right click virtual machine select Edit Settings
  • Click Options > General  > Configuration Parameters
  • Click Add Row (apparently this parameter does not exist by default, they probably should make this editable/configurable, instead of releasing a KB)
  • Under Name enter keyboard.typematicMinDelay  In the Value field  2000000
  • Click OK
  • Power on the virtual machine
Else, you'd need to locate the respective datastore for that virtual machine and edit the VMX configuration file

What would you Expect?

Catchy title for a boring task. I've been tasked to collect patch status reports for over a minimum of 120 linux servers and change the support password that we used to login. And you're not allowed to use key-based authentication for ssh in order to log myself in each and one of the servers.

Deploying my public over a minimum of 120 linux servers is a pain. I've heard about expect from a friend who told me that you could automate almost everything with expect. From spawning the initial ssh session to the password input. Is that cool or is that cool.
