For a work related project, I wanted to run the Juniper vSRX firewall (v15.1X49-D110) on my work laptop by using VMWare Workstation Pro 14. Unfortunately, the installation (importing the Juniper vSRX OVA file resulted in a VMWare Workstation crash.
In my previous blogpost, the Sonoff worked, but was lacking a manual override. The switch could only be triggered by Domoticz. Since it also has a physical push button (connected to GPIO0 (D3)), it can be switched by hand. All that needs to be done is:
- Create a new switch device in the Sonoff
- Enable 'Rules' in the Tools / advanced settings
- Create a rule
- Change the On/Off commands in the switch parameters in Domoticz
The Sonoff TH16 is an inexpensive piece of hardware that can be controlled over WiFi. Apart from the switch (that's capable of handling electrical currents up to 16A) there's an interface for temperature and humidity. The actual temp/humid sensor is sold separately (in most cases).
E-mail spam is still annoying as hell. Especially when someone else is sending e-mail on your behalf, and even more annoying if your e-mail address is used for phishing purposes.
From a protocol (SMTP) perspective, there's not much that can be done. SPAM wasn't something they thought of when they developed it in the early 80's. But there are several enhancements that can be used to prevent others by abusing your e-mail (domain). These enhancements are:
- Sender Policy Framework (SPF)
- Domain Keys Identified Mail (DKIM)
- Domain-based Message Authentication, Reporting and Conformance (DMARC)
