While installing YumaBench and trying to use it against a non-Yuma Netconf server, I noticed that SSH Hostkey Types are restricted to “ssh-rsa, ssh-dss”.
Since the server I used, only supports more secure EC based methods (like ed25519), the connection setup failed.
IMHO this might be a problem in YumaBench not being very future proof in this regards.
Also using sshlib2, which doesn’t seem to offer more options in the near future.
This might affect also other Yuma client or server software (like yangcli), but I didn’t investigate.
