DEFAULT_CONNECT_OPTIONS option for NetBackup servers and clients
The DEFAULT_CONNECT_OPTIONS option specifies the default values for the CONNECT_OPTIONS configuration option. If a host name is not specified in any CONNECT_OPTIONS option, the value from the DEFAULT_CONNECT_OPTIONS option is used.
Note:
The DEFAULT_CONNECT_OPTIONS apply to connections to the local host only; they do not apply to connections to remote hosts.
See CONNECT_OPTIONS option for NetBackup servers and clients.
Table: DEFAULT_CONNECT_OPTIONS information
Usage | Description |
|---|---|
Where to use | On NetBackup master servers, media servers, or clients. |
How to use | Use the nbgetconfig and the nbsetconfig commands to view, add, or change the option. For information about these commands, see the NetBackup Commands Reference Guide. Use the following format: DEFAULT_CONNECT_OPTIONS = [ 0 | 1 ][ 0 | 1 ][ 0 | 1 | 2 ] The default value is 0 1 0. This option should appear only once in the configuration file. |
The first setting indicates the type of port to use as the source port when connecting to the bpcd daemon port on the local host. It also indicates the type of server port if using the traditional call-back method. 0 = Connections on this computer should use a reserved port number. They are selected from the CLIENT_RESERVED_PORT_WINDOW range for source ports and from the SERVER_RESERVED_PORT_WINDOW range if using the traditional call-back method. 1 = Connections on this computer should use a non-reserved port number. Connections are selected from the CLIENT_PORT_WINDOW range for source ports and from the SERVER_PORT_WINDOW range if using the traditional call-back method. | |
The second setting indicates the call-back method to use. (This setting applies if configured to use the daemon port or if bpcd cannot be reached using ports 1556 or 13724.) 0 = Use the traditional call-back method. The destination host connects back to a random port number that this computer has selected from the SERVER_RESERVED_PORT_WINDOW range, or the SERVER_PORT_WINDOW range as determined by the first setting. 1 = Use the vnetd no call-back method. Connect to vnetd instead of a random port. Attempt to connect to port 1556 before attempting to connect to vnetd. The connection is outbound to the destination host if the third setting is 0 or 1. The connection is inbound if the third setting is 2. | |
The third setting affects which destination port number to use when attempting connections to daemon services on the destination host. 0 = Use PBX or vnetd to connect to a daemon on the destination host if possible, otherwise connect by using the traditional port number of the daemon. Attempt to connect to port 1556 before attempting to connect to vnetd. If bpcd is reachable through port 1556 or vnetd, then the first two settings are ignored and all connections are outbound and use non-reserved ports. 1 = Connect to a daemon on the destination host by using PBX or vnetd. Attempt to connect to port 1556 before attempting to connect to vnetd. The traditional port number of the daemon will not be used if the connection cannot be established using port 1556 or vnetd. If bpcd is reachable through port 1556 or vnetd, then the first two settings are ignored and all connections are outbound and use non-reserved ports. 2 = Connect to a daemon on the destination host by using the traditional port number of the daemon only. The first setting is used to determine the port range and the second setting is used to determine the call-back method. | |
