    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…

  • Blockchain

    Probably the best and easiest to understand Blockchain explanation I’ve seen. (Source)

  • EVA and WiFi

    So I am flying EVA from SIN – TPE – JFK and back. For the first time I also went to the dark side (16hrs was too long to be locked up with just my mind) and got onboard WiFi. This seems to come with unlimited data for ~20USD for 24hrs. I manage to stream…

  • Yard Sale – Free pick up

  • 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…

  • Postfix delete mails from/to one address

    Postfix delete mails from/to one address

    Monit suddenly sending 18.000 e-mail? Gmail blocking your mx IP & getting all other incoming emails to your Gmail account (as it’s getting forwarded to Gmail) delayed? Have no fear… mailq | grep [email protected] | cut -d’ ‘ -f1 | xargs -rn1 postsuper -d Edit the e-mail address. Note: mainly a reminder for myself. 😉

  • Gmail & Postfix: unencrypted emails?

    If you’re running Postfix, add this line to main.cf: smtp_tls_security_level = may Restart Postfix, and retry. PS: You can set encrypt instead of may — but this can cause issues with Amavis and/or SpamAssassin.

  • Belgian banks & SSL — part 5

    Minor end of year update. No big SSL exploits have been released since (bar DH, see below). Once again, this is testing the public websites I can access. There might be other gateways, APIs, etc that are not (as) secure. It’s worthy to note that some banks are serious about security and fixing their SSL.…
