    NextDNS and NetworkManager

    A while back, I wrote about installing NetworkManager if NextDNS activate fails to work. Only… I realised that for some reason on Raspberry Pi (4), WiFi stopped working with the following errors: The WiFi SSID and password (wpa_supplicant) never changed, so I wasn’t sure what it was. However, as most Pi’s are wired I didn’t…

  • NetworkManager exit status 1

    NetworkManager exit status 1

    Recently reinstalled NextDNS on a RPi4 64bit and came across this error: It seems like NextDNS was actually running, but just throwing an error when running nextdns activate. Restarting did seem to work without throwing any error. The logs showed the same error: The solution was (as root): Looks like, instead of resolvconf, openresolv was…

  • Sony stops DNS resolvers

    The Hamburg Regional Court today ruled that they would not suspend an existing injunction against Quad9 in a case filed by Sony Music Germany. The case centers around Sony Music’s demand that Quad9’s servers located in Germany stop resolving DNS names of third-party sites which are claimed to have URLs that contain copyright infringements.

  • 0x04


    Almost 10 years after I registered 0x04.com, it’s time to part ways. Yesterday I finalised the sale of 0x04.com. My company in Singapore was called 0x04 pte. ltd. and to avoid any confusion I’ve renamed to su1 pte. ltd. su1 standing for Superuser.one. 🤷‍♂️

  • NextDNS, EdgeOS and device names

    NextDNS, EdgeOS and device names

    Noticed that NextDNS was reporting old hostnames in the logs. For example old device names (devices that changed hostnames), devices that were definitely no longer on the network, or IPs that were matched to the wrong hostnames. The culprit is how EdgeOS deals with its hosts file. Basically it just keeps all the old hosts…

    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…

  • Raspberry Pi + ad blocking + nginx

    There’s this howto that explains how to set up the RPi as ad blocker. I’ve two RPi’s acting a router and was already running dnsmasq. I decided to give it a try. Note that this howto can actually be used on any DNS serving Linux server. First of all, don’t go with the pixelserv as…
