  • 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…

All this is automated with…

    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.…
