I'm trying to SSH my RPi 3 to... basically start using it (headless, I can't have it at the monitor for long as it is not mine). I flashed a fresh SD card with the latest Raspbian Jessie Lite and it works normally (tested on a monitor). I used
to enable ssh. Safely ejected the SD card (then also reconnected it and made sure the ssh file was still there) and put it in the RPi. I got its IP address and, having it as the only device on my network, tried the SSH by
Connection refused... and yes, I can ping it. Checking the SD card back again, the ssh file was gone.
Second method I tried was using a monitor and keyboard. I enabled SSH through raspi-config and safely powered it off. Then I hooked it back to my computer's network and it was pinging normally but, again, SSH connection was refused.
I tried the exact same with a RPi 2B and another new SD card. Same outcome.
I am currently using Mac OS X 10.12.5 but I'm not sure if that would make a difference.
I would appreciate any help! Cheers!
