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. 01reconfrpc already present? version
  2. 02reconexisting service and config (do not overwrite frpc.toml)
  3. 03reconthe local port to expose is actually listening
  4. 04reconarchitecture (amd64 or arm64)

  6. 06actInstall frpcverify

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. 01The frp server is reachableVerified bytimeout 5 bash -c '</dev/tcp/${server_addr}/${server_port}' && echo ok
  2. 02Install frpcVerified byfrpc --version
  3. 03Create the frp system userVerified byid -u frp
  4. 04Write /etc/frp/frpc.tomlVerified byfrpc verify -c /etc/frp/frpc.toml && stat -c %a /etc/frp/frpc.toml
  5. 05Create the systemd serviceVerified bysystemd-analyze verify /etc/systemd/system/frpc.service && echo ok
  6. 06EnableVerified bysystemctl is-active frpc && journalctl -u frpc -n 30 --no-pager | grep -c 'start proxy success'

Guardrails

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

The frp token is a secret: do not display it, do not cat frpc.toml. Only expose the requested port, over TCP to 127.0.0.1. Do not overwrite an existing frpc.toml without a backup. frpc never runs as root.

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.

  • 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
