  • Resilio Sync on Synology stuck?

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    The Resilio Sync package that’s provided on a Synology NAS’ Packager Center is out of date (2.6.2) and has a bug that causes big files to fail to sync (and that causes a loop of endless retries).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

    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.

  • Running WireGuard in a Docker container (amd64)

    Running WireGuard in a Docker container (amd64)

    This is the 2nd post about WireGuard. So I am running two WireGuard servers — one on a Raspberry Pi 4, and one in an amd64 virtual machine. This post will be about getting WireGuard working on amd64 in a Docker container. As this container rarely get rebuild, I am running unattended-upgrades inside the container…

    WireGuard

    This is the first post of several. Next posts will focus on running WireGuard inside a Docker container on amd64 Linux and a Raspberry Pi. I’ve been running WireGuard for a few months now and I’ve been loving it. I first started using it about a year ago when in China — OpenVPN was once…

  • Smokeping

    Smokeping

    Back in the days — when I was 16 or so — Smokeping was the rage. Every colo provider in Amsterdam, every NOC, they all had their own Smokeping. Playing around with Docker I saw some Smokeping image and that made me want to set it up again. I’m running Smokeping on my server in…

  • Box — Docker shell server

    Box — Docker shell server

    A couple of months ago I had the great idea to set up a shell server in Docker. Simply because my docker skillz were quite rusty and a shell server was something I actually genuinely needed. Shell servers… so 2005. I remember in the good old IRC days people asking for (free) shell servers to…

    NextDNS + EdgeRouter + Redirecting DNS requests

    Realised I haven’t updated this in a long while (life happened). Couple of weeks ago I started to play with NextDNS — and I really recommend anyone that’s something privacy minded and cares about the stuff happening on their network. I’ve set up several configs (home, parents, FlatTurtle TurtleBox (the NUCs controlling the screens)) and…

  • Edgerouter IPsec tunnel to Fritzbox

    So, I have an EdgeRouter Lite in Singapore (Starhub) and a FritzBox in Belgium (EDPnet). This is mostly stuff that I have found from several articles, mostly from here. ERL: eth0 is WAN, eth1 (10.60.111.0/24) and eth2 (unused, not VPN’ed) are LAN FritzBoz: 192.168.1.0/24 This is the FritzBox config (go to VPN and them Import…

  • Postfix & Courier & Letsencrypt

    First of all, create your certificates (the regular way). I created one with multiple domains: webmail.rootspirit.com, mail.rootspirit.com, smtp.rootspirit.com. In my case, as the mailserver and webserver are behind a proxy (postfix, imap, Roundcube Webmail), I create the certificate on the proxy (nginx) and scp the cert to the mail server. All this is automated with…
