Hi,

I have successfully added a new Linux device, configured SSH with public key authentication, and added a few SSH-based sensors (meminfo, load average, etc).

The sensors were responding successfully but then for operational reasons I need to change the login/key used for SSH authentication to a different account.

I changed the SSH configuration on the device to use the new user/private key but no matter what I try I keep getting "Authentication Failed" error from the sensors. Tried restarting PRTG Core without success.

The Linux server being monitored is reporting "Failed publickey for <loginname>" in its auth log everytime PRTG attempts to connect.

I can successfully connect to the server using the new account via a separate SSH client configured for RSA authentication with the same exact key used in PRTG so at this point I am really stumped as to what the issue could be.

We are running PRTG 9.1.5.1900 Linux server is configured with OpenSSH and SSH2 is used

Any thorughts?

Thank you

-Ed

Dear Frank,

this is unfortunately a known issue, PRTG uses the first key "for ever", we are investigating this. Please bear with us.

best regards.
