The MIT OR Apache-2.0 SOURCE license is clean (audit found no copied copyleft); the
gaps were all binary-distribution (Layer-2). This makes the shipped artifacts honest:
- Windows host + client: bundled FFmpeg BtbN gpl-shared -> lgpl-shared (AMF/QSV/decode
unaffected; the GPL-only x264/x265 were never used), and ship the FFmpeg LGPL notice
+ license text in the installer + MSIX (licenses/).
- THIRD-PARTY-NOTICES.txt generated + bundled into installer/MSIX/deb/rpm. Offline
generator (scripts/gen-third-party-notices.{py,sh}) + cargo-about config (about.toml/
.hbs) with a permissive-only accepted-license allow-list as a copyleft regression gate.
- Reword the win32u GPU-preference hook comments to reflect independent reimplementation
(no Apollo/Sunshine GPL-3.0 source copied).
- README dual-license + inbound=outbound contributor clause + non-affiliation trademark
disclaimer; new CONTRIBUTING.md.
- LICENSE files into the standalone driver + vk-layer workspaces; deb copyright holder
aligned to "unom and the punktfunk contributors".

punktfunk-host — Debian/Ubuntu package (apt)
punktfunk-host is published as a .deb to Gitea's Debian package registry in the public
unom org, so the Ubuntu hosts update with plain apt. CI (.gitea/workflows/deb.yml) builds
and publishes on every push to main (a rolling 0.3.0~ciN.g<sha> build to the canary apt
distribution) and on vX.Y.Z tags (a clean X.Y.Z to the stable distribution, plus attached
to the unified Gitea Release). The two are separate apt distributions, so a stable box never jumps
to a canary build — see Release Channels. The repo line
below subscribes to stable; swap stable → canary for the latest main builds.
The same workflow also publishes punktfunk-web (the browser management console — pairing +
status) and punktfunk-client (the GTK4 couch/Deck client). punktfunk-host Recommends
punktfunk-web, so a default apt install punktfunk-host pulls the console too (alongside the
udev/sysctl bits) unless you've disabled weak deps; punktfunk-client is independent — install it
on the box you stream to. (punktfunk-probe is the headless reference/test tool, not packaged
here.)
Package layout mirrors the Fedora RPM (../rpm/punktfunk.spec): the host binary, the /dev/uinput
udev rule, the systemd user unit, headless session helpers, the example config, and the OpenAPI
doc. Runtime Depends are computed by dpkg-shlibdeps from the binary itself (built in the Ubuntu
26.04 rust-ci image, so the lib soname package names match the target). The NVIDIA driver
(libnvidia-encode / libEGL_nvidia / libcuda) is not a dependency — it's installed out of
band, like on the RPM side.
Install on a host (one-time)
The registry is public, so no apt auth is needed — just trust the repo's signing key:
sudo install -d -m 0755 /etc/apt/keyrings
curl -fsSL https://git.unom.io/api/packages/unom/debian/repository.key \
| sudo tee /etc/apt/keyrings/punktfunk.asc >/dev/null
echo "deb [signed-by=/etc/apt/keyrings/punktfunk.asc] https://git.unom.io/api/packages/unom/debian stable main" \
| sudo tee /etc/apt/sources.list.d/punktfunk.list
sudo apt update
sudo apt install punktfunk-host
Then, as the desktop user:
sudo usermod -aG input "$USER" # virtual gamepads (re-login to take effect)
mkdir -p ~/.config/punktfunk
cp /usr/share/punktfunk-host/host.env.example ~/.config/punktfunk/host.env # then edit
systemctl --user enable --now punktfunk-host
# Web console — enable it and read the auto-generated login password (then open http://<host-ip>:3000):
systemctl --user enable --now punktfunk-web
journalctl --user -u punktfunk-web-init | sed -n 's/.*password generated: //p'
Firewall
Open the ports the host listens on. The native punktfunk/1 plane:
- QUIC control plane: UDP 9777 (
serve --native-port Nto change). - Data plane: an ephemeral UDP port — negotiated per session, so there is no fixed port to open. For a restrictive firewall you'd need to allow a UDP range (the repo does not pin one).
And the GameStream / Moonlight ports (fixed) — only needed if you run the host with
serve --gamestream (opt-in, trusted LAN only); bare serve is native-only and doesn't open these:
| Port | Proto | Purpose |
|---|---|---|
| 47984 | TCP | HTTPS nvhttp (paired, mutual-TLS) |
| 47989 | TCP | HTTP nvhttp (/serverinfo, /pair PIN flow) |
| 48010 | TCP | RTSP handshake |
| 47998–48010 | UDP | Video RTP (+ FEC), ENet control (47999), audio (48000) |
| 5353 | UDP | mDNS auto-discovery |
The mgmt API (TCP 47990) binds to loopback by default — leave it closed unless you move it off
loopback with --mgmt-bind IP:PORT (which then requires --mgmt-token).
With ufw:
sudo ufw allow 9777/udp # punktfunk/1 control plane
sudo ufw allow 47984/tcp && sudo ufw allow 47989/tcp && sudo ufw allow 48010/tcp
sudo ufw allow 47998:48010/udp
sudo ufw allow 5353/udp
# plus the ephemeral punktfunk/1 data port — open a UDP range you reserve for it.
With raw nftables (add to your inet filter input chain):
udp dport 9777 accept # punktfunk/1 control plane
tcp dport { 47984, 47989, 48010 } accept
udp dport { 47998-48010, 5353 } accept
# plus the ephemeral punktfunk/1 data port (a reserved UDP range).
Updates
sudo apt update && sudo apt upgrade # picks up the newest published build
systemctl --user restart punktfunk-host # if the unit was already running
Build a .deb locally
VERSION=0.0.1 bash packaging/debian/build-deb.sh # -> dist/punktfunk-host_0.0.1_amd64.deb
Needs dpkg-dev (dpkg-shlibdeps, dpkg-deb). It builds the release binary first if missing.
Build it in the rust-ci image (or on an Ubuntu 26.04 box) so the resolved Depends match the
hosts; building on a GPU box is fine — the NVIDIA driver lib is filtered out either way.
