To identify the host on which the virtual machine runs, use one of these methods:

 

Query the vCenter Server database in MSSQL:

  1. Log in to to the Microsoft SQL 2005/2008 Server as an administrator.
  2. Open SQL Management Studio.
  3. Right-click the database that vCenter Server is using.
  4. Open a new query window and ensure that the vCenter Server database is selected.
  5. Run this SQL statement :

    This query returns the virtual machine ID, virtual machine name, host ID, and host name.

NordVPN

So VPN’s in my world normally surround work related matters such as a site-to-site VPN to connect two sites or buildings together.  That was however until NordVPN very kindly sent me a free trial of the software…..and I must admit I’m impressed.

So to begin with you get a huge array of download options including some Raspberry Pi and DD-WRT:

NordVPN1

The install itself is a breeze, firstly it installs virtual NIC (which is normal practice, Dell and Cisco etc all do the same with their VPN clients):

NordVPN2

Next…well its done:

NordVPN3

Before I login, click the settings button and here’s the bit I like:

DNS Servers – This fixes a common problem “DNS Leak”, yes having a VPN is great unless your DNS isn’t working properly and your “leaking” meaning potentially your DNS is being hijacked (spoofed or injected with false IPs) or being snooped upon.  This settings sorts this issue and so long as you trust NordVPN who have promised me they don’t keep any logs!

Below this is Process Kill List, which means if the VPN drops for any reason then the list processes you’ve added will be stopped.

NordVPN4

Once you login you’ll be presented with a huge array of countries to connect to and two options, either TCP or UDP:

TCP is a reliable protocol like a phone call its two way,

UDP protocol is like a post card, you know if it gets to its destination or not but is faster than TCP.

nord4

So that’s pretty much it, you can test your VPN is working by opening:

https://www.dnsleaktest.com/ – if its not then close and reopen your browser.

You now have a “safe” connect to the interweb and all its content!!

Encrypt your laptop

Posted by robd on January 11, 2012

Now if you like me work in IT then at some point in your life you will have had to encrypt a laptop with one of the various corporate encryption tools such as:

McAfee Endpoint Encryption

Sophos

Check point

etc etc etc….

Now I’m sure they all have benefits like remote kill switches and what not but personally I’ve never liked them, any of them……some take ages, some fail misserably and occasionally I have to re-build a laptop!

Recently though I came across something that for once I actually liked and its been under my nose for bloody ages!!

TrueCrypt, it encrypts and encrypts well with various Encryption Algorithms (such as AES with 256 bit key)!  So well in fact I may encrypt my own laptop with it and when it comes to IT at home I’m proper lazy!!

Also its easy, no servers and no thought, just three things!
A laptop
A Strong password
The software

(maybe a tutorial)

I would bore you with the how to install it but honestly I cant be bothered!! Search the interwebs and be amazed with the ease!
