About ConfigManual

Welcome to ConfigManual — a practical knowledge base for anyone who works with servers, networks, and communication systems. We publish clear, step-by-step guides that turn confusing documentation and scattered forum answers into instructions you can actually follow.

What We Cover

Our tutorials focus on the tools system administrators, developers, and self-hosters use every day:

• Linux administration — essential commands, networking with nmtui, firewalls (UFW and iptables), and software installation across Debian, Ubuntu, RHEL, CentOS, and Fedora.
• Networking fundamentals — how DNS works, ports and protocols, NAT, and the concepts behind everyday connectivity.
• VoIP and telephony — Asterisk setup, SIP, codecs, PBX terminology, and troubleshooting common call-quality problems.
• Developer workflows — deploying projects, working with Git and GitHub, and fixing the errors that get in your way.

Our Approach

Every guide is written and tested by hand. We aim for accuracy first: real commands, real configuration files, and explanations of why something works — not just what to type. When tools or distributions change, we update our content to keep it reliable.

Who It's For

Whether you are setting up your first home server, studying for a certification, or maintaining production infrastructure, ConfigManual is here to help you solve problems and learn faster.
