I’ve been setting up my ODROID C1+ over the last couple of evenings. One thing I noticed was that SSH wasn’t working. When connecting in to the ODroid, I was receiving the response “Read from socket failed: Connection reset by peer”. I compared my ssh settings with my linux laptop and found that they were identical, and so I had a bit of a poke around on the internet. Finally, after lots of very complicated things that were a little invasive for the setup, and a number of workarounds that involved changing settings on the perfectly serviceable client device, I found a down-voted suggestion that someone try regenerating their host keys.

sudo rm /etc/ssh/ssh_host_*

sudo ssh-keygen -A

I gave it a go, and was delighted to find everything sprung into life and I now have a working SSH server on my ODROID device.
