Hi!
I had this set up and working last year before my SD card died, and now I'm trying to set it up again, and I can't remember how I did it.
I want to set up my Pi to trigger my DSLR via gphoto2 every 10 minutes, to create a timelapse video. My Pi doesn't have much storage space, but I have a Mac on my network that's running 24/7 for other purposes, so I want to scp the files from the Pi to the Mac, automatically, with no user intervention, after it captures each photo.
I have ssh keys set up from the Mac to the Pi already, so I can ssh in to a terminal session without a password, but I can't seem to figure out the reverse.
The command in my script on the Pi is of the form:
where /home/pi/beepass is a text file on the Pi containing the password for bee@192.168.1.2, and 2024-01-28-19-56-22.jpg is the name of the latest photo.
If I run the script, it fails with:
If I attempt to execute just the scp part from the command line, e.g.:
then I get:
where "yes" is my typed response, and then I get:
I copy/paste the password from beepass, which succeeds as:
resulting in a viewable file at: /Users/bee/CombLapse/2024-01-28-19-56-22.jpg on the Mac.
So I have the user/pass correct for bee@192.168.1.2, and the file is correct; I just have sshpass and/or the keys set up incorrectly.
When I run ssh-keygen on the Pi, I get:
which doesn't make sense because I'm in .ssh/ already, so it must exist, and it currently contains:
so I ran it again and saved it to a tmp dir:
then moved the files:
So now I have what appears to be a key in the correct place:
.
which I copied to the bee dir on my mac:
but scp still generates the same "The authenticity of host '192.168.1.2 (192.168.1.2)' can't be established." error and prompts me for a password.
Do I have a really silly, obvious syntax error somewhere?
Thanks!
