Re: SSH and Android

Well, I forgot to specify I wanted to connect from RPI to Android. (It seems no one does it this way, google only finds how to use RPI as a server.) I tried juicessh, connected very well to RPI, but I did not manage to connect the other way. I did not really figure out what means "[email protected].c...

SSH and Android

There is a tutorial about SSH in the latest MagPi Magazine. I wonder why Android was not worth mentioning. SSHDroid for some reason stopped working. The bug is known and is not about to be fixed. I do not mind messing up my RPI/Windows computers, I reinstall them from scratch periodically. This is n...

I do not count the destroyed cards... 100% of times when the electricity went down.
