Port Plumber

Utility bind ports with initialization commands

Configuration

The following configuration file must be created:

$HOME/.config/portplumber/config.toml

```toml

Bind 127.0.0.1:12345 to 127.0.0.1:80

[plumbing."127.0.0.1:12345"] target = "127.0.0.1:80"

Bind 127.0.0.1:23456 to 127.0.0.1:2048

At first connection the setup command will be spawn and 500ms will be awaited before redirecting the connection to the target

[plumbing."127.0.0.1:23456"] target = "127.0.0.1:2048" resource.setup = { command = "http-server", args = ["-h", "127.0.0.1", "-p", "2048", "-v"] } resource.warmup_millis = 500 ```

Autostart

Systemd

On linux systems systemd can be used to automatically start this command on startup.

To achieve this, the following file needs to be created:

$HOME/.config/systemd/user/port-plumber.service

```ini [Unit] Description=Launch port-plumber

[Service] Type=simple ExecStart=%h/.cargo/bin/port-plumber Environment=RUST_LOG=info [Install] WantedBy=default.target ```

And the following commands needs to be executed:

• systemctl --user daemon-reload reload systemd user daemons
• systemctl --user enable port-plumber enable port-plumber daemon
