Specify the following four port numbers, which JP1/Software Distribution will use for communications:

• Software Distribution Manager (default: 30000)
• Software Distribution Client (relay system) or Software Distribution SubManager (default: 30001)
• Client call (default: 30002)
• Software Distribution HTTP Gateway (default: 22295)

Normally, you should use the default port numbers. However, you must change a port number if some other program is using that port. If a port number is set in the services file of TCP/IP, the services file setting takes precedence.

If you have installed Server core facility and Remote Installation Manager on separate PCs, make sure that the port numbers of Software Distribution Manager and Software Distribution Client (Relay system) or Software Distribution SubManager match in both PCs. If the port numbers do not match, the Remote Installation Manager cannot connect to the server.

The port number for JP1/Software Distribution HTTP Gateway is used only when JP1/Software Distribution HTTP Gateway is used. For details, see E. Using Internet Options to Install JP1/Software Distribution.

If you are not using dial-up connection, select UDP or TCP as the protocol to be used when the local system is started. The default is UDP.

If you select TCP and set a port number in the services file, also add the following entry to the services file: netmdm xxxxx/tcp (where xxxxx is the port number).

Note that programs may not start in a WAN environment if you select UDP.

When a file transfer to subsystems occurs, the file can be divided into specified units and the divided file segments are transferred at regular intervals. This transfer method can reduce the load on the network during file transfer. The default is that this check box is not selected.

Interval transfer is not performed from a subsystem to its higher system.

Number of continuous transfer buffers

File transfer buffer size specified during setup at the destination system determines the buffer's unit size. For example, if File transfer buffer size is 4,096 bytes and Number of continuous transfer buffers is set to 2, the job is divided into units of 8,192 bytes.

You can specify a value in the range from 0 to 4,294,967,295 in Number of continuous transfer buffers. The default is 1. If you specify 0, interval transfer is not performed.

Transfer interval

Specifies the interval time between transfers when interval transfer is performed. You can specify a value in the range from 0 to 4,294,967,295 milliseconds. The default is 1,000 milliseconds. If you specify 0, interval transfer is not performed.
