backup job is failing with error 57 and 58

[gurminder_singh]

Can Anybody explain me the difference between error code 57 and  58.

As per my thinking most of the time issue is because of below reasone. Kinldy let me know any major difference when we will get error 57 and when we will get error 58.

Error code 57

client services are running or not 

port on client is in listining state

check the netbackup clinet service have admin rights

connectivity to bpcd

port configuration on both side client and server

Error code 58

can't connect to client

server is not able to connect

or bpcd port on client is not on listining state and name resulation issue

code 58:

The server was unable to connect to the client.

client not available in hosts file, server not inserted to media server or master server.

code 57:

The client refused a connection on the port number for bpcd

connection available and service running, but some of ports not opened

NetBackup status code: 57

Message: client connection refused

Explanation: The client refused a connection on the port number for bpcd.

This error can occur because of the following:

• No process listening activity occurs on the bpcd port

• The number of connections to the bpcd port is more than the network subsystem can handle with the listen() call

NetBackup status code: 58

Overview: 
A status 58 error results from either a TCP SYN request sent to a client from the NetBackup (NBU) server that was not acknowledged or the server was not resolvable so a TCP SYN request was not sent. The majority of the causes of this issue are due to the client not listening on the BPCD or VNETD ports, the master server unable to resolve the client by hostname, or the client can not resolve the NBU server by its IP address. NBU clients running 6.x release, though it uses the vnetd daemon for incoming connections, it still requires bpcd to perform the hostname compare to authenticate the NBU server.

When NBU is not at all installed on a client, it will also cause status 57.

So, my experience:

Status 57:
NBU software not installed
NBU Client service not running (Windows)
bpcd and/or vnetd not running (Unix/Linux)

Status 58:
Port connectivity
Forward/reverse name lookup issue
