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.
- 01recondistro and version: apt (Debian/Ubuntu) or dnf (RHEL/Fedora/Rocky/Alma)?
- 02reconCertbot already present (package or snap)?
- 03recondoes a certificate already exist for this domain? when does it expire?
- 04reconis the chosen web server running? (required by the certbot plugin)
- 05recondoes the domain point to this server’s public IP?
- 06reconis a firewall (ufw or firewalld) active?
- 07actInstall Certbot + ${webserver} pluginverify
- 08actIssue the certificateverify
- 09actAutomatic renewalverify
- 10actHTTPS respondsverify
SEC.02
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.
- 01verifyInstall Certbot + ${webserver} pluginVerified by
certbot --version - 02verifyIssue the certificateVerified by
certbot certificates -d ${domain} 2>/dev/null | grep -c "VALID" - 03verifyAutomatic renewalVerified by

curl -s -o /dev/null -w '%{http_code}' https://${domain}/
SEC.03
Guardrails
Non-negotiable instructions the run must respect, whatever it finds on the server.
The domain must point to this server (A/AAAA) and port 80 must be reachable before issuance. Respect the rate limits: never loop on attempts, test with --dry-run. Do not revoke or delete an existing certificate.

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.
search by intent — type “firewall”, get ufw
- 01Read-only reconnaissance before any change
- 02Every command signed by your browser, approved by you
- 03Each step verified before the run moves on, every run kept in the history
