The greatest challenge to any thinker is stating the problem in a way that will allow a solution

Welcome to vBlog, a personal record of my techy tinkerings and particular ponderings.

I tend to focus on VMware virtualisation, and the interaction/automation of it using PowerCLI (VMware's PowerShell Snapin), but anything that I happen to stumble across that seems like it might be of use at a later date, may well get recorded here.

I also maintain vWiki, which was a predecessor to this blog. Wiki's are great for quickly recording snippets of info, but tend not to look that great; Blog's are better looking things, but seem to require more effort so that the posts/articles are accessible in their own right. As a result I tend to update both interchangeably as available time, and depth of thought, permit.

If you happen to find anything of use, or in need of correction please leave a comment. Knowing that my ramblings are of some use is a great reward; and similarly I'd hate to waste anybody's time by feeding them duff info.

See these pages for me info about me, and my vBlog, and below for my recent posts...

To my mind, the beauty of a truly powerful scripting language, is the sense that you can achieve anything that you might need to. You just need to apply yourself, and the full force of Google, and be prepared for a bit of trial and error.

The fact that PowerShell let’s you unleash the full might of the .NET army means that this is pretty much true for it. Recently I head the need to be able to interact with a number of Vyatta routers (see my SSH to Vyatta Router Using PowerShell post), in order to be able to get a load of virtual machine’s NAT’ed addresses, and found two possible solutions, one of which is fairly well documented on the Web (which I struggled to get on with), the other of which is new (in beta still at time of writing) and not particularly prevalent, but seems very flexible….

While not a daily requirement, every so often I find myself needing to set-up a virtual router.  The first time I came across Vyatta was when setting up a VMware lab-in-a-box, and more recently to replicate the functionality provided by the Virtual Router in a VMware Lab Manager unfenced lab (I’ll explain later if you don’t know what that is).

The best part of a Vyatta router is, like most things in life, that it’s free (for the Core version – which provides all the routing functions that you’d normally expect from a router).

This post will take you through the basic set-up for a router, and them some configuration examples for a few useful set-ups. Continue reading →
