A server that waits two minutes for the network at every boot slows down every patch window. Here’s how to
I started TecMint in 2012 as a side project from my apartment because most Linux content online felt either too academic or copied straight from official docs. So I built the resource I wished existed when I was a junior sysadmin, practical guides written by someone who has actually broken things at 3 AM and figured out why.
Sixteen years later, the site is still here, and so am I. Every article is still tested on a real machine before it gets published. I've never found a better rule.
Learn the Linux basics with two free courses and join 34,000+ readers getting practical TecMint tutorials and selected Pro TecMint articles every week.
TecMint once reached over 5 million monthly readers at its peak. Over the years, the internet changed, search evolved, and more people began using AI tools to find answers. But the goal never changed: publish Linux tutorials that are tested, practical, and genuinely useful.

"I've been in IT for 26 years as a Network Administrator, primarily in Windows environments. When our storage architect left, I had to step into Linux with very little prior experience. TecMint made the learning curve much smoother. Using the platform, I was able to create a shell script, definitely the most Linux thing I've done so far."
"I passed the RHCSA on my first attempt. The certification course covered every exam topic and the practice questions were exactly what I needed. Six months later, I'm using those same skills at work every day."
"I've been reading TecMint since 2016. The articles are always tested on real systems, you can tell because the commands actually work. I've used it to set up a dozen servers and troubleshoot things I couldn't find documented anywhere else."
"Switched from Windows to Linux two years ago. TecMint was my main reference for the first year. The Bash scripting series saved me hours of manual work. I automated 3 of my daily tasks within a week of reading through it."
"The SSH course is the most thorough I've found anywhere. I've been using SSH for years but still found chapters that filled real gaps in my knowledge. Worth it for the tunneling and key management sections alone."
"I started with Learn Linux in 7 Days as a complete beginner. By day 4 I was comfortable at the command line, and by the end of the week I had SSH access to my first VPS. Clear, practical, and no fluff."
