Linux Sysadmin | Agent Skills Atlas

About this skill

Operate and harden Linux hosts — SSH, systemd services, users/permissions, package management, networking, firewall, log triage, and resource inspection. Use when configuring a server, writing a systemd unit, hardening SSH, debugging "the box is slow / a port won't bind / a service won't start", setting up a firewall, or triaging a host under load. Targets Debian/Ubuntu + RHEL/Fedora families. Triggers — "ssh", "systemd", "the server", "permission denied", "port in use", "service won't start", "harden the box", "set up the VPS", "linux". Pairs with deployment-cicd (containers/pipelines), incident-response (host on fire), security-web (app-side hardening), shell-scripting (the automation).
