GCP VM Error creating interface while trying to join to network #191

franciscosuca commented 3 years ago

I am trying to connect to the server using a virtual machine from the google cloud platform (GCP), but after following the quick-start guide I get the following errors :

Replicate scenario:

  1. Installed wireguard apt install wireguard
  2. Join the network using curl -sfL https://raw.githubusercontent.com/gravitl/netmaker/v0.5/scripts/netclient-install.slim.sh | KEY=MY_TOKEN

You are either missing the Wireguard kernel module (OPENVZ e.g. does not include it in many VPS e.g.) or you use boringtun (which is a userland implementation of Wireguard).

@afeiszli There are userland implementations of Wireguard which can be called with the following wg-quick command example for a Wireguard tunnel based on boringtun:

WG_SUDO=1 WG_QUICK_USERSPACE_IMPLEMENTATION=boringtun wg-quick up wg0

Any chance to patch this into netmaker? It will help to integrate many VPS providers that do not allow the kernel module Wireguard.

Thanks in advance!

@cmprmsd we do want to switch to using wg-quick. It would make management a lot easier. Right now we are using the official golang package wgctrl which seems to be lacking in some functionality. It will take some refactoring to use wg-quick but we'll get that roadmapped.

@franciscosuca have you checked your wireguard implementation like @cmprmsd is mentioning?

Also, what is your base operating system?

Try running this manually. It will confirm if wireguard interface type is not available on your host:

sudo ip link add dev helloworld type wireguard sudo ip link show

(if it succeeds you can remove with "sudo ip link del helloworld")
