<error detail>
Describes the error that occurred.
Cause: An error occurred when trying to forward a connection.
Effect: The forwarding request fails.
Recovery: Any corrective action depends on <error detail>. A typical error is a failure to connect to the target

<interface>
Is the IP address of the local interface the SSH client tries to establish a listen for.
<port>

Effect: The forwarding request is rejected.
Recovery: If forwarding is desired, check the setting of ALLOWTCPFORWARDING.

Session Related Messages of SSH2 in Client Mode
All SSH2 messages related to an outgoing connection to a remote SSH daemon initiated by a NonStop client process
(e.g. SFTP, SFTPOSS) are preceded by a session ID. These messages adhere to the following format:
<session id> := <process id>
<process name> is the name of the NonStop client process initiating the SSH connection.
<session id>: client access to known host <known host name> denied, host is frozen
