Nexus passwordless SFTP copy with public key not working

Hello,

I have a Nexus 9000 and unfortunately can't use Prime for management. I want to copy the current configuration to a sftp server using passwordless public key authentication. I have configured a local user without a password and generated a public/private key pair for it, like described in Chapter: Configuring SSH and Telnet. I have copied the public key to the sftp server and now try to use the following command to copy the configuration

 

copy running-configuration scp://nw_backup@nwbackup.example.com/backup/config.txt vrf default

 

But it's asking for a password. I can also see in the sftp server debug logs that the client doesn't use public key authentication. I have copied the private key to my desktop and can login with it without entering a password.

 

Nexus9# show username nw_backup keypair

What is the problem? Do I have to set a local password for the account or is it not allowed to use an _ in the username? The copy works, if I enter the password for the user on the sftp server.

 

Thanks,

Patrick
