I am Tyler J. Wagner, and I’m a Linux systems, network, and satellite engineer. I live in London and frequently travel to Europe and the Middle East on business. I have lived in San Francisco, Amsterdam, Baghdad, and Erbil (Iraqi Kurdistan). I am an American/British dual national. I hold a B.S. Computer Science from California Polytechnic State University, San Luis Obispo. I can be found on Facebook, Google+, Twitter, and LinkedIn. If you’ve seen a user named “tolaris” almost anywhere, that’s probably me.

I am the Chief Technology Officer of Talia Ltd, a satellite Internet services provider and Linux consulting and network engineering company. Talia operates its own teleport and maintains a VSAT network spanning 8 satellites and 1500 modems across the Middle East, South Asia, and Africa. Every day, we are responsible for keeping 140 mbit of traffic moving along 250 MHz of committed satellite spectrum.

I manage a team of engineers responsible for our company infrastructure, which includes 70 Linux servers and 25 Linux workstations. Our servers run a mix of Ubuntu, CentOS and RHEL, and our workstations run Ubuntu and Linux Mint. I have managed some form of Unix since I was introduced to HP-UX 9 in 1996, and have run Linux on the desktop full time since 2005.

My wife and I lived in Iraq from August 2003 to May 2005, where I worked for ServiceSat International, now IraqSat, an Iraqi satellite-based ISP. You can read about our experiences there in the archive of our personal blogs at giantlaser.livejournal.com and slownewsday.livejournal.com. I recommend you start here. A friend also wrote a reasonably accurate article about my time there; it’s an entertaining read if you have the time.

These are my thoughts on Linux, VSAT, and network engineering.
