VMware Workstation: Generate a new selfsigned SSL/TLS certificate

Hi,

the VMware Workstation does not provide a program or script to generate a new pair of key and selfsigned certificate.

If’ve written a batch file which builds a new one. The scripts assumes that the Workstation is installed in the default folder C:\Program Files (x86)\VMware\VMware Workstation and uses the openssl command delivered with the program.

Adjust the Countryname, State, etc. to your own needs. Config is based on the VMware Docs.

Script to get a list of computers connected to a Avocent KVM switch

Hello,

in his office, a customer have a few Avocent KVM switches to control some client computers in a remote room. He ask me about the possibility to get a list of all computers connected to these boxes, because he do not want to maintain any list by hand.

I research the documention but there is no (scripting) interface from which I could get such a list. SSH is only for connecting serial consoles, SNMP offers no OIDs for such a case.

Because of the costs, DSView isn’t a option. The only way seems to be to extracting the list by reading the Webfrontend HTML output. Let us do this 🙂

I wrote a script in powershell, at least version 2 is needed to handle selfsigned SSL certificates, which do the following:

  • Login to the Webfronted with https and SSL encryption by System.Net.HTTPWebRequest class to get the authentification cookie
  • Get the Device HTML  page by .NET class System.Net.Webclient and using Authentification cookie
  • Save HTML do a temporary file
  • Open the file with Internet Explorer
  • Get the URL to start a KVM session, computername and portnumber by  DOM

Script details

Define the User, Password, protocol and the devices:

# KVM User
[string]$sUser="Admin"
# KVM Password
[string]$sPassword="YourPassword"
# Protocol
[string]$sProtocol="https"
# Your Devices
[String[]]$aAvocentDevices=@("Console1.domain.local","Console2.domain.local")

Built HTTP POST text and disable SSL certificate warnings
