Last night I
SSH'ed to different systems.... one system/SSH reported that the "
authenticity of HOSTNAME couldn't be established......." and it asks if I want to continue or something, I didn't and found this peculiar so I tried to
SSH to the system from one of the systems I already had
SSH access/open, which didn't report that message(which means no change to the system since last login).
Then I looked at my
~/.ssh/known_hosts and the system was in there so it should know the host I was connecting from, then tried again using the up/down arrows to browse bash history so I didn't make any mistakes in the commands and I didn't...
And this time it worked without any notice about failed authenticity and asked for the password as usual.
Should I be worried, was this as Debian say's "someone doing something nasty"?
The point is... why the message, then not the message(without me doing or changing anything)..... weird.
