About OnLinux.ro
OnLinux.ro is a technical publication focused on practical Linux administration, servers, security, networking, Docker, virtualization and self-hosting.
The goal is simple: publish technical guides that can actually be used in real environments, with clear explanations, practical commands, configuration examples and troubleshooting steps.
What you will find here
OnLinux.ro covers infrastructure topics ranging from a single Linux server or homelab to virtualization and clustered environments.
- Linux installation and administration;
- Ubuntu, Debian, AlmaLinux and Rocky Linux;
- server hardening and security;
- SSH, firewalling and VPN technologies;
- WireGuard;
- Docker and containers;
- Proxmox VE and virtualization;
- backup and disaster recovery;
- networking;
- monitoring and troubleshooting;
- open-source and self-hosted applications.
Practical first
The focus of OnLinux.ro is not simply explaining what a technology is. Whenever possible, articles include the commands, configuration files, verification steps and troubleshooting techniques required to deploy it.
A tutorial should leave you with a working system and an understanding of why it works.
Security matters
Many tutorials published here involve services exposed to a network or to the Internet. Security therefore forms an important part of the content.
Guides aim to include relevant practices such as least privilege, firewall rules, SSH key authentication, access control, backups, monitoring and recovery planning whenever they apply.
Homelab and production
A homelab is one of the best environments for learning Linux, virtualization, networking and automation.
At the same time, recommendations that are appropriate for a laboratory environment are not always appropriate for production. Articles therefore try to clearly distinguish between experimental configurations and production-minded designs.
Open source
OnLinux.ro has a strong focus on open-source technologies and solutions that administrators can understand, operate and control themselves.
This includes Linux itself as well as technologies such as Proxmox VE, WireGuard, Docker, ZFS, Ceph and many self-hosted applications.
The English edition
OnLinux.ro was originally published in Romanian. Selected guides are now also being made available in English.
The English articles are reviewed as independent technical content rather than being published as raw machine translations. Commands, configuration examples and technical terminology remain consistent with the software being documented.
Keep learning
Linux infrastructure is constantly evolving. New kernels, distributions, virtualization platforms and security practices continue to change the way systems are deployed and operated.
OnLinux.ro aims to document those technologies in a practical and reproducible way.
