### Install GotaTun Executable

Source: https://github.com/mullvad/gotatun/blob/main/README.md

Installs the GotaTun executable to the Cargo bin directory. This command is an alternative to manually copying the binary from the target release folder.

```bash
cargo install --bin gotatun --path .
```

--------------------------------

### Run GotaTun Tunnel

Source: https://github.com/mullvad/gotatun/blob/main/README.md

Starts a GotaTun tunnel. The `-f` or `--foreground` flag keeps the process in the foreground. Replace `INTERFACE-NAME` with the desired interface name.

```bash
gotatun [-f/--foreground] INTERFACE-NAME
```

--------------------------------

### Run wg-quick with GotaTun

Source: https://github.com/mullvad/gotatun/blob/main/README.md

Configures and brings up a WireGuard tunnel using `wg-quick` with GotaTun as the userspace implementation. `WG_SUDO=1` is used to ensure necessary privileges. Replace `CONFIGURATION` with the path to your WireGuard configuration file.

```bash
sudo WG_QUICK_USERSPACE_IMPLEMENTATION=gotatun WG_SUDO=1 wg-quick up CONFIGURATION
```

--------------------------------

### Build GotaTun Executable

Source: https://github.com/mullvad/gotatun/blob/main/README.md

Use this command to build the GotaTun executable binary. The `--release` flag enables optimizations. A target triple can be specified for cross-compilation.

```bash
cargo build --bin gotatun --release [--target $(TARGET_TRIPLE)]
```

--------------------------------

### Build GotaTun with Nix

Source: https://github.com/mullvad/gotatun/blob/main/README.md

Builds the GotaTun executable using Nix. The resulting binary will be located in the `result/bin/gotatun` path.

```bash
nix build .#gotatun
```

--------------------------------

### Build GotaTun Library

Source: https://github.com/mullvad/gotatun/blob/main/README.md

Use this command to build only the GotaTun library. The `--no-default-features` flag is used to exclude default features, and `--release` enables optimizations. A target triple can be specified for cross-compilation.

```bash
cargo build --lib --no-default-features --release [--target $(TARGET_TRIPLE)]
```

--------------------------------

### Grant CAP_NET_ADMIN Capability

Source: https://github.com/mullvad/gotatun/blob/main/README.md

Grants the `CAP_NET_ADMIN` capability to the GotaTun executable, which is required for network administration tasks. This allows GotaTun to create and manage network interfaces without needing to run as root.

```bash
sudo setcap cap_net_admin+epi gotatun
```
