Re: Hacking into raspberry using gpio 14/15 pins

Can the potential hacker change that compromised raspberrys rx pin to tx pin on software The RX pin can be configured as an output, but as you say the attacker cannot reconfigure the TX pin at the other end. This does leave a denial of service or sabotage attack, though. If you have two GPIOs conne...

Re: Hacking into raspberry using gpio 14/15 pins

The scenario is Pi1 is compromised and connected via serial link to an uncompromised Pi2. Whether Pi2 can be compromised or not would depend on the software listening to the serial link on Pi2. So apparently I can just go with Ground and one cable (from tx to rx). So now at least I can't send anyth...

Re: Hacking into raspberry using gpio 14/15 pins

http://security.stackexchange.com/questions/17364/vulnerability-of-a-computer-behind-a-serial-port Pretty much like this problem, but replace "computer east 1" with raspberry that reads data through serial and sends it forward (this part is already taken care of), and "computer east 2" with raspberr...

Hacking into raspberry using gpio 14/15 pins

Hi, I've two raspberries, one with software that is reading serial port (dev/ttyAMA0) and one with software that is sending data to that other raspberry, but not reading anything. Is it possible to hack into the raspberry that is sending data, even if there is no software (made by me at least, I don...

Re: Raspberry Pi / Davis Vantage Pro2 weather station

I don't really mind the looks of the string, I just want to snip the outtemperature, humidity, raintick, windspeed, winddir, uv and solarrad, and I'm currently really out of my natural habitat with all this python stuff.

Re: Raspberry Pi / Davis Vantage Pro2 weather station

Hi, Exactly what data does s hold? Yeah, weather data obviously, but I mean if you print s out as a string, what does it look like? I'm supposed to do pretty much this same thing, but I don't have the weatherstation. I've looked for the documentation, but either It doesn't have raw example of what d...
