Linux Server Administration in Mannheim
I design, harden, and operate Linux servers for small environments, personal infrastructure, web services, and self-hosted setups.
Stable operations over ad-hoc fixes
The work focuses on clean base setup, updates, firewall rules, SSH access, backup paths, and monitoring. Services should survive restarts and be debuggable when something fails.
Documented and maintainable
I prefer short runbooks, reproducible configuration, and clear boundaries between the operating system, container stacks, and public entry points.
Typical Work
- AlmaLinux, Debian, Ubuntu, and RHEL-like systems
- SSH hardening, firewall, updates, and baseline configuration
- Systemd, logs, storage, backups, and monitoring
- Migration of small services into maintainable server structures
