ssh-agent identities and "no SSH identity provided"

[wolfgangrupprecht]

When using ssh identities and keys stored in the ssh-agent btrbk has no problem logging in and getting the remote snapshots yet the warning still gets printed.

WARNING: No SSH identity provided (option ssh_identity is not set) for: ssh://example/mnt/btr_pool/root

Perhaps the warning could be stored and only printed if the ssh fails?

Thanks for reporting!

The idea behind this warning was to simplify first steps, as most users would probably want to set ssh_identity. As it is not required, warning on every run is simply wrong, so I turned it into a hint displayed along with SSH errors:

(note: option "ssh_identity" is not set, using ssh defaults)

fixed in cf2065df308d81f5503d3dc0f0c96cd09d7b9de7, along with some other SSH related improvements I had lying around:

• allow disabling ssh_identity and ssh_user options
• tidy btrbk.conf.example
