VMware: Cannot connect from vCenter Webclient to VDP Appliance

Hi,

the license of VMware vSphere 5.1 includes the diskbased Backup Solution VDP(vSphere Data Protection). So I’ve decited to try the appliance (Version 5.1 Timestamp 2012-10-02) whether these meets our requirements.

Before I started, I ensured that

  • The DNS forward and reverse resolution of the choosen name and IP address is possible.
  • The User, who manage the backup, have vCenter Administrator rights.
  • all prerequisites are fulfilled

Downloading and installing of the appliance works as expected. The Appliance is properly registered in the vSphere Webclient but I can’t start the VDP Frontend within.

Error Message

Error Message

Error: Could not connect to the requested VDP appliance. Would you like to be directed to the VDP configuration screen to throubleshoot the issue.

But whats wrong? I’m currently logged on to the Webclient with my Domain Login. When I’m using SSO Administrator admin@system-domain Login the VDP Frontends starts,
also another Domain Login can connect. Something in the chain Windows Domain, Single Sign On, vCenter and VDP Appliance fails.

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
