I have been trying to setup passwordless SSH for a Backuppc system. I
have three Debian 10 systems (including the server) . SSH sets up
fine on one of the client machine and "ssh backuppc@192.168.254.xx
starts without asking for a password. The other machine (supposedly
identical) not only asks for a password but will not accept any of the
known passwords. If I go to the offending machine and attempt to su
to the backuppc user , I am asked for a password and no passwords
work. This doesn't allow the use of ssh-copy-id for transfering the
encryption key to that machine. I have tried to reset the backuppc
password three times but did not solve the problem. In both systems
the public key is stored in /var/lib/backuppc/.ssh as id_rsa.pub.
I also have a Windoz 7 laptop that I want to include and have managed
to get ssh and rsync installed (what a mess that was). I have not
tried to get passwordless access to that yet. For later.
Any insights?
