Generating Wireguard QR codes for fast mobile deployments

Originally published at: https://serversideup.net/generating-wireguard-qr-codes-for-fast-mobile-deployments/

If you have been following along on my Gain Flexibility & Increase Privacy with Wireguard VPN “mini-course”, you’ll notice that there are a few areas that we need apply configurations in order for our devices to get connected. Typing all of this in manually on mobile can be a massive pain, especially if you are…

Hi Jay,
Excellent guide on setting up WireGuide. However, on ‘qrencode -t ansiutf8 < /etc/wireguard/clients/BlackViewA80Pro.conf’ (having used BlackViewA80Pro for all the mobile usage in this section), I got ‘bash: qrencode -t ansiutf8 < /etc/wireguard/clients/BlackViewA80Pro.conf: Permission denied’.
I’ve tried preceding the command with sudo and also with ./, but both gave the same. Any ideas? I’m actually using Xubuntu 20.04 but I don’t know of any difference in Terminal command between that and Ubuntu 20.04.

Thanks for the compliments!

That is very strange qrencode, especially if you already ran it with sudo.

I wonder if it has something to do with the redirection in Bash? https://askubuntu.com/questions/230476/how-to-solve-permission-denied-when-using-sudo-with-redirection-in-bash

Basically, try switching so you become root then try running the command without sudo.

Hopefully that works!
