marcusholtz/i2p-party-line-box repository overview

⁠marcusholtz/i2p-party-line-box

Distrobox-ready image for encrypted push-to-talk voice and group party line over I2P⁠. No accounts, no phone numbers, no servers, no open ports.

Built for Distrobox⁠, not Docker Compose. Your mic, speakers, and network are shared with the container automatically. Ideal for immutable or atomic Linux distros (Bazzite, Silverblue, SteamOS, etc.).

For Docker Compose or standalone Docker usage, see marcusholtz/i2p-party-line⁠.

⁠Supported Architectures

Architecture	Tag
x86-64	`amd64`

⁠Quick Start

⁠Create and enter

distrobox create --image marcusholtz/i2p-party-line-box:latest --name partyline-i2p
distrobox enter partyline-i2p

⁠Run the party line

Once inside the container:

i2p-party-line.sh

Optional. Once inside the container, run:

distrobox-export --app /usr/share/applications/i2p-party-line.desktop

Use the full path (/usr/share/applications/tor-party-line.desktop).

"I2P Party Line (on partyline-i2p)" appears in your host application menu with its own icon and opens in a terminal. Remove it with the same command plus --delete.

To also run it from your host shell:

distrobox-export --bin /usr/local/bin/i2p-party-line.sh --export-path ~/.local/bin

⁠Alternative registries

# GitHub Container Registry
distrobox create --image ghcr.io/marcusholtz/i2p-party-line-box:latest --name partyline-i2p

# GitLab Container Registry
distrobox create --image registry.gitlab.com/marcusholtz/i2p-party-line/box:latest --name partyline-i2p

⁠One-command setup with distrobox.ini

A distrobox.ini manifest is included in the source repo⁠. It creates the container, exports i2p-party-line.sh to ~/.local/bin, and adds no menu entries:

distrobox assemble create --file distrobox.ini

After assembly, run i2p-party-line.sh directly from your host shell.

For an application menu (.desktop) entry, uncomment the exported_apps line in distrobox.ini before assembling, or use the distrobox-export command above.

⁠First Run

i2pd reseeds and builds tunnels (~23 s for relay, ~86 s for calls from cold start)
Your .b32.i2p address appears (no ports needed; I2P routes through tunnel gateways)
Press 1 to set a shared secret (both sides need the same one)
Share your address + secret, one side listens, the other calls

Your destination key persists inside the distrobox home directory across restarts.

⁠What's Inside

Everything pre-installed, no first-run dependency installation needed:

i2pd
Opus codec, OpenSSL, socat
PulseAudio utilities, ALSA utilities
QR code generation (qrencode)
pcm_rms (compiled C audio level meter)
i2p-party-line.sh at /usr/local/bin/

⁠How It Differs from the Docker Image

	Docker image	Distrobox image
Image	`i2p-party-line`	`i2p-party-line-box`
Run with	`docker compose` / `docker run`	`distrobox create` + `distrobox enter`
Audio	PulseAudio socket bind-mount + `/dev/snd`	Automatic host audio passthrough
Network	Container networking	Host network (shared)
User mapping	Container root	Mapped to your host user
Entrypoint	Custom entrypoint	None (distrobox manages init)

⁠Security

Property	Detail
Encryption	AES-256-CBC + PBKDF2 + HMAC-SHA256
Relay	Zero-knowledge: forwards blobs, never has the secret
Authentication	`.b32.i2p` address + pre-shared secret
Forward secrecy	None; rotate secrets between conversations
Source	Single bash script, no binaries, no telemetry

⁠The Party Line Trifecta (Distrobox)

Three networks, same app, same encryption:



I2P Party Line	Reticulum Party Line⁠	Tor Party Line⁠
