Re: Raspberry pi 3 Model B WiFi MAC address keeps changing

I'm suddenly running into something similar on the wlan0 port of my pi3. This thread seems to be all over the place. Did anyone find a specific cause to investigate?

Re: simple heartbeat

you could also convert it to use values submitted on the command line by changing the `for a in` line to:

Code: Select all

for a in $*

I've been playing around with various host monitoring tools primarily looking for something very lightweight for checking up-status of my growing collection of Pis.

Re: Python Questions - py2exe?

OK, py2exe may not be able to create programs that will run on raspberry pi, but there's no reason it couldn't create exe files that would run on a windows machine. It just needs to cross compile to suit the target platform. Now that doesn't mean anyone has ported the code over, but creating an exe ...

They say that they have to use qemu for many components which means it would run very slow on arm.
