dsh-net-dashboard

A live network inspection dashboard in the DeepSeek Harness sidebar: interfaces and IP/MAC, traffic rates, TCP/UDP sessions, and latency curves, all read from this machine at request time and refreshed every 3 seconds.

What it does

The panel sits under the built-in sidebar rows and shows the current machine's network quality. It is key-first: a KPI strip and four cards, each collapsed to its essentials with a 详情 (Details) disclosure.

• KPI strip — download rate, upload rate, gateway latency and TCP session count, always visible.
• Live traffic — aggregate download/upload rates (loopback excluded) with rolling curves and peaks. Details adds per-interface rates and cumulative in/out counters.
• Latency — one compact row per target: current value, loss chip and a 1-second-resolution mini curve. The default gateway is always followed; a public target is configurable. Details adds average / min / max / jitter / loss / received-sent statistics.
• Sessions — TCP session total, UDP socket count and the top state bars. Details adds the full TCP state breakdown and a session-count trend.
• Network — primary interface with IPv4, gateway, DNS resolvers and public IP at a glance. Details adds IPv6, MAC, Wi-Fi facts, hostname, OS version and a full interface table with live per-interface rates.

Install

dsh plugin --profile desktop add "github:foreee/dsh-net-dashboard"

Use --profile web for the browser profile. The Web Plugins page and the plugin_manager tool accept the same address. The plugin ships plain JavaScript — no build step, no dependencies.

How it works

The host half (lib/index.js) mounts one loopback-only route, GET /api/net-dashboard/snapshot:

• Each request runs ifconfig, route, netstat and scutil --dns (all bounded), plus ipconfig getsummary for Wi-Fi facts.
• Traffic rates come from diffing netstat -ib byte counters against the previous sample held in memory.
• Latency is fed by persistent ping -i 1 child processes (one per target, restarted on failure, stopped with the plugin) into a rolling window; the route only reads that window, so a 3-second poll never spawns command storms.
• The public IP lookup is cached for 10 minutes and can be disabled.

The browser half (lib/client.js) polls the snapshot every 3 seconds (toggleable, persisted in localStorage), keeps its own rolling history for the traffic and session curves, and draws every chart as inline SVG — no chart dependency. Colors use the shell theme tokens, so light and dark themes both work.

Routes

Route	Method	Purpose
api/net-dashboard/snapshot	GET	one full snapshot: interfaces, primary facts, traffic, sessions, latency

The route sits behind a loopback-only trust fence (loopback socket and loopback Host header, same-origin markers enforced); paired remote devices are rejected.

Configuration

Field	Default	Meaning
enabled	true	set false to mount nothing
pingTargets	["223.5.5.5"]	extra latency targets; the default gateway is always followed
publicIp	true	enable the cached public IP lookup

Requirements and limitations

• The collector commands and parsers target macOS.
• Without Location permission macOS hides Wi-Fi SSID/RSSI; those rows are simply omitted.
• Traffic rates need two snapshots to materialize, so the first poll shows —.

Development

node --test test/*.test.js   # parser, trust-fence and loopback-guard tests
node --check lib/index.js && node --check lib/client.js
