TL;DR Unix geek tries Windows 10 for a year. For the most part it works, but lots of growing pains. Going back to the land of GNU. Introduction A year ago, I started an attempt to give Windows another try. I jump around different platforms to stay current and cognisant of the industry shifts professionally. The need to get back to Windows happen to coincide with need for a new laptop. ...
In order to make full use of my half-duplex WiMAX link, I started looking for anything and everything I could use to optimize it. Linux has some pretty decent utilities with iproute2 and netem to handle these type of configurations. They don’t compare to OpenBSD’s PF, but they work once you get the setup in place. Due in part to how ugly TC is out of the box, I really like FireQOS for defining the basic configuration. The developer also makes a great iptables wrapper called FireHOL, but iptables rules are easy enough to write in my opinion. ...
Simulating WAN links used to be a difficult process. I would load FreeBSD with a dummynet driver and play with the settings to tweak where I needed it for the activity. OpenBSD with ALTQ made this a step simpler with the ease of bridging adapters. On a recent project for Spec Ops Technology, I needed to simulate a WAN with latency, loss, and randomness. I decided I needed to dig more into the netem work included in most recent linux distributions. Netem has matured to the point of being a very potent utility for setting up quick testbeds. Additionally with most any modern Linux distro you are online in minutes. I will post a very quick script to get you online: ...
—- Cross Post from the Spec Ops Technology Blog —- Spec Ops Technology prides itself on taking difficult problems and providing practical engineering solutions. Quite often this real world experience is born of a real world problem we personally faced. There is a passion we look for in our engineers that breeds a team that, by nature, develops creative fixes. As the United and Lufthansa ticket counters can attest, I spend a lot of time on the road. In today’s connected world I depend on a secure and platform agnostic internet connection. There a few major hurdles that make this difficult: ...

In my past there was formidable travel, but it always was within the continental US which removed some of the complexities in life. With the crossing of borders the type of equipment you need changes dramatically. Below are some of my favorite items to carry that have saved me numerous times. In a later post I will cover the software and mobile applications that I use on all this stuff. ...
