The build script sets its own `$GOPATH`, so the build environment is self-contained.

- Should work out of the box on most Linux distributions with `iproute2` installed.
- systemd service scripts are included in the `contrib/systemd/` folder so that it runs automatically in the background (using `/etc/yggdrasil.conf` for configuration):
- Copy the service files into `/etc/systemd/system`
- Copy `yggdrasil` into your `$PATH`, i.e. `/usr/bin`
- Enable the service:
```
systemctl enable yggdrasil
systemctl start yggdrasil
```

```
systemctl status yggdrasil
journalctl -u yggdrasil

- Tested and working on Windows 7 and Windows 10, and should work on any recent versions of Windows, but it depends on the [OpenVPN TAP driver](https://openvpn.net/index.php/open-source/downloads.html) being installed first.
- Has been proven to work with both the [NDIS 5](https://swupdate.openvpn.org/community/releases/tap-windows-9.9.2_3.exe) (`tap-windows-9.9.2_3`) driver and the [NDIS 6](https://swupdate.openvpn.org/community/releases/tap-windows-9.21.2.exe) (`tap-windows-9.21.2`) driver, however there are substantial performance issues with the NDIS 6 driver therefore it is recommended to use the NDIS 5 driver instead.
- Be aware that connectivity issues can occur on Windows if multiple IPv6 addresses from the `fd00::/8` prefix are assigned to the TAP interface. If this happens, then you may need to manually remove the old/unused addresses from the interface (though the code has a workaround in place to do this automatically in some cases).
- Yggdrasil can be installed as a Windows service so that it runs automatically in the background. From an Administrator Command Prompt:
```
sc create yggdrasil binpath= "\"C:\path\to\yggdrasil.exe\" -useconffile \"C:\path\to\yggdrasil.conf\""
sc config yggdrasil displayname= "Yggdrasil Service"
sc config yggdrasil start= "auto"
sc start yggdrasil
```
- Alternatively, if you want the service to autoconfigure instead of using an `yggdrasil.conf`, replace the `sc create` line from above with:
```
sc create yggdrasil binpath= "\"C:\path\to\yggdrasil.exe\" -autoconf"
```
