How to become a Certified IPv6 Technician – Part Two

Internet Protocol version 6 (IPv6) is the “new” Internet addressing protocol created by the Internet Engineering Task Force (IETF) to deal with the exhaustion of the current IPv4 address space. In Part One of this article I gave you some background in IPv6 and documented your path from IPv6 Certified Newb to Enthusiast. In Part Two we’ll finish the Hurricane Electric IPv6 Certification process and you’ll be end up being a Sage. Administrator The IPv6 Administrator not only runs a valid IPv6 addressed web site, but also a valid IPv6 addressed mail server. For this certification, you’re going to have to configure a mail server that resolves via IPv6 DNS, can be connected to over IPv6, and...

How to become a Certified IPv6 Technician - Part One

Internet Protocol version 6 (IPv6) is the “new” Internet addressing protocol created by the Internet Engineering Task Force (IETF) to deal with the exhaustion of the current IPv4 address space. What does that mean to you and I? Ultimately, it means very little. The transition from IPv4 to IPv6 has been going on, very slowly, for the last 13 years. However, something rather significant occurred on February 1, 2011, the last IPv4 blocks were allocated from IANA to the Regional Internet Registries (RIR) around the world. That means there are no more Internet Protocol version 4 addresses left to allocate to those authorities. So, when they’ve been allocated out, they’re gone forever.

What I Learned about Time Machine backups from timedog

I love Time Machine. For years and years backups were something I was supposed to do, but never found the time to do. Backups were difficult, you had to purchase backup software, find a drive, set them up, and then either manually execute your backup (which is what I did for years) or figure out how to automate them. Enter Time Machine With the launch of Mac OS X 10.5 (“Leopard”), Apple included this brand new Backup system. But, this article isn’t about Time Machine. Perhaps I’ll do one of those at some point. This article is about what I just learned about TIme Machine. I’m backing up a lot of stuff I shouldn’t be…...

Adobe Type Units Error - How to Fix It

The Problem I was recently perusing my /var/log/system.log file under OS X Snow Leopard (OS X 10.6.6), also available by running the Console application in your Utilities folder and selecting system.log, when I noticed several error messages that bothered me: osascript[236]: Error loading /Library/ScriptingAdditions/Adobe Unit Types.osax/Contents/MacOS/Adobe Unit Types: dlopen(/Library/ScriptingAdditions/Adobe Unit Types.osax/Contents/MacOS/Adobe Unit Types, 262): no suitable image found.

OSX Hints and Tips

There are many ways to customize your OSX environment to suit your personal tastes. However, not every preference you want to change can be modified using System Preferences or Application Preferences. Often, settings are deemed too obscure for everyday users and relegated to complex keystrokes or hidden system settings. This is my guide to a number of these that can make your life a little easier, or your experience a little better. OSX Keystroke Shortcuts I’ll start with a series of keystrokes that are available in different contexts while you use your Macintosh. These are not your normal keystrokes that are self-documented underneath application menus, these are hidden gems you’ll want to become familiar with: Start-up Keystrokes (hold...
