Upgrading ESX 3.5 to vSphere 4 Using Host Update

Tonight I decided to go on the magical journey of upgrading my ESX 3.5 environment to vSphere using the Host Update Utility.  I’m usually a firm believer in ‘If it ain’t broke, don’t fix it!’ but this time I decided to take the plunge and see what happens.
A few months ago, I ran through the [...]

Vyatta Firewall Basics and Configuration

A few weeks ago, I installed Vyatta Open Source as a router internal to my network to see how it handled traffic between multiple subnets.  To put it plainly, it worked like a champ!  I put the router in place, assigned IP addresses to the NICs (network interface cards), and let the system do its [...]

I’ve always considered it to be common knowledge that ‘host headers’ could be used to allow IIS to handle multiple web sites [...]

Network Security Appliance for Free: Untangle

About a year ago a good friend, Bobby Shea, introduced me to Untangle.  I finally got around to implementing it on my network and I’ve found it to be an amazing system.
Untangle is an open source scaled down Linux implementation that can turn your old throw away PCs into commercial grade network appliances.  Why spend [...]
