Running WireGuard in a Docker container (RPi)

This follows the my two other posts about WireGuard.

Most of this can be copied from the amd64 post — with a minor change for making it work on RPi4. This is the full git repo (including both rpi and amd64).

The main difference is in the file. The installation is a bit different and we’ll need to install the Raspberry Pi kernel headers.

WireGuard is also installed from testing instead of Debian backports.

Note that for older RPi’s (ie gen 1) you’ll need to compile from scratch.



This is a rant.

I’ve dealt with quite a few (bad) banks over the course of my life across countries and businesses.

And I think HSBC is one of the worst.

For various reasons. But mostly for being stuck in another century.

And you’d expect a tiny (Belgian) bank to be horrible. Not one of the biggest banks in the world with branches in almost every country of the world.

But no. HSBC pretty much tops it.

I have tons of other examples how and why HSBC failed me, and by the end of the year I think it’s time to part ways.

Resilio Sync on Synology stuck?

The Resilio Sync package that’s provided on a Synology NAS’ Packager Center is out of date (2.6.2) and has a bug that causes big files to fail to sync (and that causes a loop of endless retries).

The solution is to manually update the package from 2.6.2 to 2.6.4. Find your NAS architecture and then download (bottom of the page) the right binary and manually install it.

Note that you need to stop the Resilio Sync service running (manually stop it via Package Center) before uploading the package and installing it.

Once done, don’t forget to manually start the service again.

Resilio Sync GUI will be at <NAS IP>:28888/gui/.

The howto guide to manually update the package can be found here.

Error! Bad return status for module build on kernel: 4.19.0-8-amd64 (x86_64)

I was rebuilding my WireGuard Docker container today and this error started popping up:

The solution was to install bc. Seems like Debian is not pulling the right dependencies. I’ll be adding it to my Dockerfile.
