Using Your Home DNS Servers with Corporate VPNs

Among IT pros, it’s quite common these days to have a home lab/home network complete with DNS, DHCP, hypervisors, storage, etc. As IT pros, it’s also quite common to have to use a virtual private network (VPN) solution to connect back to our employers’ corporate networks in order to get work done. In this post, I’ll show you how you can reconcile these two (sometimes conflicting) situations with a relatively little-known feature in OS X. (This post builds upon an article on this same feature that I published in 2006.)

Introduction to Networking: Part 1, The Basics

This is the kick-off to a series of posts introducing networking concepts to VMware administrators. Based on the feedback I’ve gotten in speaking to VMware admins, networking is an area in which a lot of VMware-focused folks aren’t particularly comfortable. So, I thought it might be helpful to put up a few blog posts on networking concepts for VMware administrators. (If you’re already familiar with networking concepts, you probably don’t need to read this—unless you just have some free time on your hands.)

A Short Dry Spell

It’s been a couple of weeks since I published anything here, so I wanted to just provide a brief update. I know that posting something about why I haven’t posted something isodd, I guess you could say. In any case, a number of factors—some personal, some professional—have contributed to why I haven’t been able to generate some useful new content in the last couple of weeks. Of course, there are blogs that go for months between posts, so a small gap of a couple weeks isn’t really a big deal. After over 8 years (I started blogging in May 2005), I think you can rest assured that I have no intention of shutting down anytime soon.

Reducing the Friction: Processing E-Mail, Part 2

A few weeks ago I published a Reducing the Friction blog post centered on helping to streamline the tasks involved in processing e-mail. (Recall that there is a distinction between managing e-mail and processing e-mail.) In this Reducing the Friction post, I’d like to revisit the idea of processing e-mail with a slightly different take: using text expanders to streamline composing and replying to e-mail messages.

Thinking Out Loud: The Future of VLANs

It’s interesting to me how much the idea of a VLAN has invaded the consciousness of data center IT professionals. Data center folks primarily tasked with managing compute workloads are nearly as familiar with VLANs as their colleagues primarily tasked with managing network connectivity. However, as networking undergoes a transformation at the hands of SDN, NFV, and network virtualization, what will happen to the VLAN?

Reducing the Friction: Using Keyboard Shortcuts

One thing that I personally have found extremely helpful in making common tasks easier—a key aspect of the “reducing the friction” idea I’ve been discussing—is the use of keyboard shortcuts. In this post, I want to talk about how you might be able to maximize your use of keyboard shortcuts to help improve your personal efficiency.

Resources for Networking and Network Virtualization

Good friend (and now colleague) John Troyer asked me via e-mail if I had a “reading list” for networking and network virtualization. I didn’t have a formally-prepared “reading list,” so I just shared with John some of the resources that I personally use. John’s response was: “You should blog this.” So, here it is—a list of resources for networking and network virtualization.
