SSH Shell Entry Failed to Connect

Shell entry failed to connect with interactive authentication.

An unknown SSH error was encountered.

No authentication method available

Errors appear when connecting with an SSH Shell in RDM 2019.X.



Interactive authentication in terminal is set to True under Advanced tab.

Under File – Options – Types – Terminal , interactive authentication in terminal is also configurable.


Change the value to False if Interactive authentication in terminal is not required.

Alternative Solution

Adding lines in SSH server may break the authentication process. Never perform this without a backup.

If interactive authentication is required to confirm that the SSH server includes lines :

KbdInteractiveAuthentication yes
ChallengeResponseAuthentication yes
UseLogin no
UsePam yes
