Status Code: 57

Client connection refused



The client refused a connection on the port number for bpcd.  This can occur when the client has not been properly configured to accept connections from the master server.  This can also occur due to name resolution issues or due to a misconfiguration of the client services.



1      Detailed explanation详细解释


A NetBackup process was unable to connect to the NetBackup Client Service process bpcd.


The NetBackup Client Service (bpcd) listens vicariously through the local service manager (like inetd in UNIX or bpinetd in Windows) on port 13782 for other NetBackup processes to contact it.  The bpcd process could also be run standalone without a service manager like xinetd running.


This contact can be host-to-host communication or IPC communication within a single host. If the requesting process fails to successfully connect to bpcd through port 13782, a Status 57 is generated. This can occur because there is no bpcd process listening on port 13782 or there are more connections to the bpcd port then the network subsystem can handle with the listen() call.


In Figure 1, you can see how the NetBackup processes connect through bpinetd during a normal backup:
