Collection of useful, relevant or inane places on the the Internets for 2 Sep 2011:
- Easy Unix tools for Network Engineers – Lots of people enjoyed this post by Mike Kantowksi on Packet Pushers
I thought I’d write about some unix tools I use every day. Below are some examples of common unix programs and a tiny little bit of scripting along with it. These are building blocks to greater things, but even taken by themselves, they can save you a lot of time. Enjoy!
- Using Cygwin to Boost Your Toolkit | Majornetwork – Markku talks about installing Cygwin on Windows so you can use the tips From Mike (in the previous topic) on Windows.
Using command line tools is often very natural for network specialists as that really is the way of configuring the devices in straight-forward way, and traditionally that has made it possible to automate certain things easily. That concept also extends to other environments, and Cygwin is one of my favorite tools on Windows computers because it brings some useful tools to my reach without too much extra effort. Of course I could run Linux or some other system that provides familiar interfaces for CLI work but currently Cygwin just does the job.
- Arista – Understanding VXLAN Virtual Layer 2 Networks– Arista outlines their version of VXLAN. It’s worth noting that Arista have some unique capability with the VMtracer and integrating that with VXLAN offers some unique value to customers.Interesting ideas. Software flexibility is an advantage, but it’s also a curse for performance. I wonder which will win.
- Cisco IOS Hints and Tricks: Finally: MAC-over-IP-based vCloud networking – Ivan getting it right on VXLan. If that’s all VMware can do for networking, we have a big problem.
Even with the remaining drawbacks, the MAC-in-IP encapsulation is way better than VLANs or MAC-in-MAC encapsulation we had so far, and I’m positive Cisco will eventually make the next logical steps.
- Red Sweater Blog – Word Breaks For Nerds – Starting in Lion, Apple fine-tuned the behavior by changing the definition of what constitutes a word delimiter for option-arrow navigation. While it used to stop on e.g. period-separated words, now it considers such chains.of.words to be a single “word.”
- The CNET Download.com Installer – If you website isn’t making money, then close it down but don’t turn to dodgy affiliate marketing practices and pretend it’s “for the customer”.
The CNET Download.com Installer is clearly adware. It might make sense to use a different download portal in the future, especially if you do not want to download the 400 Kilobyte web installer every time you download a file from the download site.
