CONNECT_OPTIONS option for NetBackup servers
The CONNECT_OPTIONS apply to connections to the local host only, as follows (they do not apply to connections to remote hosts):
Whether subsequent call-back connections with host use the traditional call-back method, use vnetd, or use a PBX/vnetd forwarding connection.
Whether connections to host use reserved or a non-reserved source port number.
Table: CONNECT_OPTIONS information
Usage | Description |
|---|---|
Where to use | On NetBackup primary servers or media servers. |
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: CONNECT_OPTIONS = host [ 0 | 1 | 2 ] [ 0 | 1 | 2 ] The following variables are defined: Host is a host name local to this host. You may have multiple CONNECT_OPTIONS entries in the configuration, and localhost overrides other local host names. If a local host name is not specified in any CONNECT_OPTIONS entries, the values from the DEFAULT_CONNECT_OPTIONS option are used. |
The first setting indicates the type of port to use as the source port for connections to service daemons on host: 0 = Connections on this computer should be from a reserved source port number. 1 = Connections on this computer should be from a non-reserved source port number that is selected from the CLIENT_PORT_WINDOW range. (The default is 1.) In the NetBackup web UI, open the media server host properties and select . 2 = Use the method that the DEFAULT_CONNECT_OPTIONS configuration option defines. | |
|
The second setting indicates the call-back method to use with host. (This method applies if bpcd cannot be reached using ports 1556 or 13724.) 0 = Use the traditional call-back method. Host connects back to a random port number that this computer has selected from the SERVER_RESERVED_PORT_WINDOW range, or 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. 2 = Use the method that the DEFAULT_CONNECT_OPTIONS configuration option defines (default). | |
Example 1 | The configuration file can contain CONNECT_OPTIONS settings for local host names. CONNECT_OPTIONS = localhost 0 0 In this example, local connections to daemons on the local host shark attempt to use port 1556. If the previous attempt was unsuccessful, then the connections try vnetd. If the connections are successful using 1556 or vnetd, then both settings are ignored. $ bptestbpcd -host shark 0 0 10.82.105.11:40402 -> 10.82.105.11:1556 10.82.105.11:40404 -> 10.82.105.11:1556 |
Example 2 |
CONNECT_OPTIONS = host 0 1 In this example:

Example 3 |
CONNECT_OPTIONS = host 1 1 In this example:
