In the IPv4 TCP/IP NJE, TCP/IP signon processing, OPEN/OPEN SSL and ACK records are exchanged by either of the connecting nodes. If the connection is secured by SSL, an OPEN SSL record is exchanged instead of an OPEN record. If the RHOST value in the OPEN , OPEN SSL or ACK records is not valid (that is expected by the node receiving the record), the error message is issued.
The socket connection is brought down after issuing this message.
Notify the system programmer.
If this message is issued for an inbound connection and the rcdtype is OPEN/OPEN SSL, the remote node probably filled in its node name or its IP address incorrectly in the OPEN/OPEN SSL record. Contact that node and verify that the correct node name or number is associated with the IP address it is attempting to connect to.
If this message is issued for an outbound connection and the rcdtype is ACK, the remote node accepted the OPEN/OPEN SSL sent by the local node, however sent its RHOST (its node name or its IP address) incorrectly in the ACK record. Contact the remote node and verify that it has correctly defined the local node.
