devplace-node
Native donor client for the DevPlace community node network. One static Go binary, standard library only.
What you share
When running, and only inside the limits you configured:
- Your internet connection and your IP address, used to fetch public pages from the destinations on the allowlist (today:
reddit.com,redd.itand their subdomains) over ports 80 and 443, GET only. - The fetched public page, which DevPlace receives and may cache for a short time.
- Byte counters (up and down) so your daily cap and your lifetime totals are correct.
What is never shared
- Your cookies, logins, accounts and browser. The client has no cookie jar and drops
Cookie,AuthorizationandProxy-Authorizationfrom every request. It uses no browser profile and reads no files besides its own config. - Any access to your local network: addresses that are private, loopback, link-local, CGNAT or multicast are refused after local DNS resolution, and the connection goes to the address that was checked.
- Any destination outside the baked-in allowlist. A list sent by the server can only be equal or narrower. Redirects that leave the allowlist are refused.
- Anything on ports other than 80 and 443.
The device secret (dpn_...) is stored in the config file with mode 0600 and is never logged or printed.
Use
devplace-node login --server https://devplace.net --secret dpn_...
devplace-node status
devplace-node run
devplace-node version
Create the device secret on your DevPlace profile after consenting to bandwidth sharing. login asks the server to accept the secret before storing it (--no-verify skips that). The secret can also come from DEVPLACE_NODE_SECRET. Every command takes --config PATH.
run is quiet: it logs start, disconnects, and one totals line per day. Add -v for detail. Exit code 3 means the server ended this device for good (revoked, suspended, kill switch, no consent, not adult, replaced by another instance of the same device); fix the cause and start it again.
Config file
Stored at <user config dir>/devplace-node/config.json, with usage.json (today's byte count) beside it.
{
"server": "https://devplace.net",
"secret": "dpn_...",
"bandwidth_mb_day": 500,
"max_concurrent": 2,
"max_tunnels": 2,
"active_from": "",
"active_to": "",
"timezone": ""
}
active_from and active_to are HH:MM in timezone (empty means the system timezone); a window may wrap midnight. These limits are enforced locally and the server can only make them stricter.
Build and package
./build.sh [outdir] cross-compiles linux/amd64, linux/arm64, darwin/arm64, darwin/amd64 and windows/amd64 with CGO_ENABLED=0 -trimpath, and writes manifest.json (name, os, arch, sha256, size, version) beside the binaries. VERSION=1.2.3 ./build.sh overrides the version.
packaging/ holds a systemd user unit (loginctl enable-linger $USER keeps it running without a login), a launchd plist, a Windows scheduled-task script and a container compose file.
