The playbook

The run starts read-only: the recon probes decide what happens next. The steps that follow are adapted to the distribution and state found — a real machine is rarely clean.

1. 01reconthe distribution: apt (Debian/Ubuntu) or dnf (RHEL/Fedora/Rocky/Alma)
2. 02reconLynis already present?
3. 03recona previous report (to compare the score)
4. 04actEnable EPEL (RHEL/Rocky/Alma only)verify
5. 05actInstall Lynisverify
6. 06actRun the auditverify
7. 07actExtract warnings and suggestionsverify

What it verifies

Each step ships its own check. The run only moves on when the check passes, so what the recipe reports as done is what is actually on the server.

1. 01verifyEnable EPEL (RHEL/Rocky/Alma only)Verified bydnf repolist enabled | grep -ci epel
2. 02verifyInstall LynisVerified bylynis show version

Guardrails

Non-negotiable instructions the run must respect, whatever it finds on the server.

SEC.04

How a recipe runs in Servor

Servor is zero-knowledge: the platform cannot execute anything on its own. When you launch this recipe, a run reads the reconnaissance, plans the steps and asks for your approval. Each approved command is signed by your browser — with a key the server never sees — then relayed verbatim to the agent, which verifies the signature locally before executing.

Deploy on Servor button

Maintain Lynis audit or a project that needs it? Put this button in your README or on your site: one click and your users install it on their own server.
