WordPress pingback ddos

Woke up to a whole pile of uptime alarms flagging that various websites were not “up” and responding. Azure, Jetpack, Cloudflare – something was clearly wrong.

As you can see from the Apache access logs – hundreds of thousands of hits per minute from the same IP address range – 185.188.204.x

Easy fix to create a deny rule in Azure to block this. I don’t think CloudFlare was touching it.

Office 365 and postfix – revisited

Since I wrote this post (a long, long time ago) – Office 365 now adds support for creating a trusted connector between your Linux/postfix environment and Office 365.

Much, much easier than before.

https://support.office.com/en-us/article/How-to-set-up-a-multifunction-device-or-application-to-send-email-using-Office-365-69f58e99-c550-4274-ad18-c805d654b4c4

So as a reminder for me next time:

  • certificate
  • SASL for username/password
  • Postfix main.cf settings
  • Set up Office 365 connector and trusted IP end point

Tumble Dryer

Sometimes life is not about technology.

Tumble dryer stopped heating – so take it apart, realise thermal fuse is blown. Clean all of the dust and lint out – reassemble – it works for a few minutes.

Repeat and rinse. This time replace thermal fuse, thermostat and heating element. Same again.

Third time run the vent pipe cleaner up the pipe – and there’s a birds nest in the vent pipe. Desiccated dead bird and all.

Moral of the story – tumble dryer problems – always clean and clean the vent just to be extra sure.
