SSH connection




I can SSH login, using Putty, to one of my Linux servers and everything is fine.

When I use the same credentials within PRTG to setup a file monitoring sensor I get "Logon failure unknown user name or bad password." error.

What am I missing?

Can you help please?

the file and folder sensors in PRTG all use SMB and Windows API calls, which won't work on Linux machines (and then also the security context in which the PRTG Probe Service is running, which probably won't be able to logon to a Linux host as well).

best regards.

Thanks for your quick reply.

To try to get this to work I have mapped a Windows drive on my PRTG server to the Linux SMB share and can access it fine using the same user context PRTG is running under.

I have created a new Sensor to point to the file on the mapped drive but now I get an error says that part of the path is missing. Curiously in the error message the colon is replaced by a dot (don't know if that's relevant) So R:\filename.xxx is reported as R.\filename.xxx in the error text. I am using

Any ideas?

Please try running the PRTG Probe Service under another account as well. The colon being replaced by a period is only an internal issue to avoid HTML-Problems.
