I concur with this. I have been using a single SD Card to test the hardware
for each of the Gate Valves that I am currently building for WMT. Each time I
SSH into the newly built device, I get this message because the hardware has
changed, but the IP address hasn't so the PC I'm using smells a rat.
I can accept this situation because it is easier to simply delete the old key
and create a new one. In your message the line:
Offending ECDSA key in /home/peterm/.ssh/known_hosts:8
remove with:
ssh-keygen -f "/home/peterm/.ssh/known_hosts" -R "192.168.1.9"
tells you how. You will then be able to log in after agreeing to generate a
new key.
