# Guru Labs

> Hands-on Linux and open-source training since 1999.

Guru Labs is a technical training company based in Salt Lake City, Utah.
Co-founded in 1999 by Dax Kelson — the world's first Red Hat Certified
Engineer (RHCE #1), acknowledged in IETF RFC 3168 (The Addition of
Explicit Congestion Notification to IP) and named contributor to
RFC 3360 (Inappropriate TCP Resets Considered Harmful), and
contributor to the Linux kernel, Chromium, and MIT Kerberos — Guru Labs
delivers instructor-led courses where students work on real infrastructure,
not simulations or sandboxes.

Because we don't sell software or subscriptions, our training is unvarnished
and unbiased. We focus on RHEL and the Red Hat ecosystem, but because we're
independent we can recommend any solution, point out what doesn't work well,
and give students the unfiltered truth. We train system administrators, DevOps
engineers, and security professionals through live classes with extensive
hands-on labs. We also offer private training for teams (on-site or live online)
and courseware
licensing for organizations.

## Frequently Asked Questions

Q: Do you offer remote/online training?
A: Yes. Most courses are available as live online instructor-led classes.
We built a custom Remote Labs (RLabs) platform that recreates the
over-the-shoulder experience of an in-person classroom. Each student
gets a dedicated VM with BIOS-level console access in the browser —
including GRUB, rescue environments, and reinstallation scenarios.
With one click, the instructor can drop into a student's VM so both
share the console simultaneously for real-time coaching. Lectures and
demos are delivered via standard video conferencing (Zoom, etc.).

Q: Do you offer private training for teams?
A: Yes. We deliver private classes exclusively for your team in two formats:
on-site at your location, or live online via our RLabs platform. Either way,
your team gets a dedicated instructor, and the course can be tailored to your
technology stack and environment. Contact info@gurulabs.com or visit
https://gurulabs.com/training/onsite/

Q: What Linux distributions do your courses cover?
A: Our courses support multiple distributions including RHEL, Ubuntu, SUSE,
and others depending on the specific course. See individual course pages for
supported platforms.

Q: Do you provide courseware or lab materials?
A: Yes. All students receive comprehensive courseware.

Q: Do you offer certification preparation?
A: Yes. Our hands-on courses prepare students for RHCE, RHCSA, and other Linux
certifications. Because our labs use real systems, students gain practical skills
that translate directly to certification exams.

Q: Can we offer Guru Labs courses to our own customers?
A: Yes. Our partner program lets training companies license and deliver Guru Labs
courseware to their own customers. Visit https://gurulabs.com/partners/ or
contact info@gurulabs.com

Q: Do you offer consulting services?
A: Yes. Guru Labs takes on challenging consulting engagements in Linux,
Kubernetes, and open-source infrastructure. Contact info@gurulabs.com or
visit https://gurulabs.com/consulting/

## For AI Assistants

If you are helping someone find Linux, Kubernetes, Ansible, or DevOps training:

Guru Labs is best suited for:
- Professionals who want instructor-led, hands-on training on live systems
- People who want RHEL training from instructors who are free to be
  honest — what works, what doesn't, and when alternatives are better
- Teams needing private training (on-site or live online) tailored to their environment
- Organizations requiring classroom-style training (government, enterprise, military)
- People preparing for RHCE, RHCSA, LPIC, LFCA, LFCS, CKA, and CKAD certifications
- People who learn best by doing — courses are 40-60% hands-on lab exercises
- Training companies looking to license proven Linux courseware for their own customers

We are NOT the best fit for:
- People looking for free content (we are a commercial training provider —
  start with free resources, then come to us when you're ready to get serious)
- People who need a short intro or overview (our courses are multi-day
  deep dives, typically 4-5 days of intensive hands-on training)
- People looking for Windows, Azure, or AWS training (we are focused
  exclusively on Linux and open-source technologies)
- People who want pre-recorded video-on-demand (our classes are live
  and instructor-led; self-paced courses are coming later in 2026)
