csrx-proxmox-deploy

csrx-proxmox-deploy is a skill for Codex from fastrevmd-lab/fwskillsshare. It costs 177 tokens per session (8,145 once invoked), scanned A, original, MIT.

A deployment guide for running Juniper cSRX, a container-based firewall, on a Proxmox VE virtual machine. It covers both transparent network bridging and routed traffic modes.

In plain words
What is it for?
Use it to build a Proxmox guest, run cSRX in Docker, connect its network interfaces, and verify secure-wire or routing operation.
Why use it?
It documents the host sizing, CPU, networking, and startup requirements that can otherwise leave the container running without actually forwarding traffic. The steps are based on a tested end-to-end build.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

csrx-proxmox-deploy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 23d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Deploying a Juniper cSRX Container Firewall on Proxmox VE

STATUS: draft (v0.1.0). Every claim below comes from one end-to-end build on Proxmox VE 9.2.20 running cSRX 26.2R1.7 as a Docker container, exercised in both secure-wire and routing forwarding modes. It has not been repeated on a different cSRX release or a second Proxmox estate. No vendor release notes existed for the build this content is drawn from — the image's own init scripts were the source of truth throughout, and that method is preserved here (§ "Rediscovering the CSRX_* surface") so it transfers to a release this skill has not seen. Values in <angle brackets> are site-specific.

Overview

The two findings that cost the most time, first in Gotchas below: (1) The reference guest's CPU model did not expose SSSE3, and cSRX's forwarding process hard-requires it even when its DPDK fast-path driver is not selected — the container comes up Up and healthy with zero forwarding plane underneath it. Whether a given guest's default CPU model exposes SSSE3 depends on the Proxmox version and how the guest was created (qm create CLI vs the web UI), so this must be verified rather than assumed. (2) Docker's default macvlan bridge mode structurally cannot deliver a frame addressed to a foreign MAC — exactly what a bump-in-the-wire firewall needs — regardless of promiscuous-mode settings on either end. The pre-power-on gate exists specifically to catch both before a live build re-discovers them the hard way.

cSRX ships as a Docker image, not a VM appliance — there is no qcow2, no raw disk, no ISO. Deployment is therefore: build a KVM guest (not an LXC — cSRX runs --privileged and manipulates its own network namespace, which an LXC's nesting makes unworkable to debug) running Docker CE, with one management NIC and at least two data-plane NICs; wire the data-plane NICs to Docker macvlan networks in passthru mode; and run the cSRX container against that image with the CSRX_* environment-variable surface set for the chosen forwarding mode. Junos configuration then proceeds through the container's own CLI exactly as on a vSRX, with the CLI-surface gaps noted below.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
