Subject Re: Help with SFTP processor
Date Tue, 04 Apr 2017 16:27:53 GMT
Good afternoon,

I would try this command from command line:

ssh -vvv -i <path to rsa file> user@server

Example:

ssh -vvv -i /some/path/.ssh/id_rsa nifi@10.10.10.10

If that works then I would double check the "private key path" property of
your GetSFTP it should point to the fully qualified file to the private key
path.

If it does not work then the -vvv option should give you more error.
