Communication page

Specify the following four port numbers, which the client 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 a Packager is installed, the values that you specify here also apply to the Packager.

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

(2) Protocol used by the higher system requesting the client to start a job

Select the communications protocol for receiving execution requests from the higher system. The following two protocols can be selected:

UDP
TCP

You can select both protocols. If the system uses a firewall, you must select the TCP protocol. The default is that both protocols are selected.

Connect to the upper-level system by using the IP address received via the startup request protocol

Select this check box to enable the higher system to be connected even when the higher system's name cannot be resolved. By default, this check box is not selected.

When a host name is used for an ID key for operations, the client may not be able to resolve the higher system's name in some environments, such as where a quarantine system prohibits the client from connecting to the DNS server or the higher system uses multiple network adapters. If this check box is selected in such cases, the IP address in execution request information is stored at the time the execution request information is received from the higher system, enabling the client to connect to the higher system.

For details about the connection settings applicable when the client cannot resolve the higher system's name, see 6.5.6 Connection settings when the name of the higher system cannot be resolved in the Description and Planning Guide.

This check box is enabled when the TCP or UDP check box is selected. In the setup of client facilities for a relay manager/system, this check box is always disabled.

Note

There is no need to set this option if an IP address is used as the ID key for operations.
If the higher system's version is earlier than 06-71, connection cannot be established correctly even with this check box selected.
If the higher system is a cluster system, connection may not be established correctly.
If the communication protocol used for execution request information is UDP, connection may not be established correctly in an environment where the higher system uses multiple network adapters.

(3) File transfer buffer size

Specify the size of the buffer that the local system is to use for file transfer with the higher system. Increasing the buffer size improves transfer efficiency. However, if the buffer size is large, the higher system must have a memory size equal to buffer size x number of clients that can be connected concurrently. Adjust the buffer size according to the memory size of the higher system. Specify the buffer size in the range from 512 to 4,096 bytes. The default is 4,096 bytes.

Note that the file transfer buffer size for UNIX Software Distribution version 01-09 or earlier is fixed at 1,024 bytes; therefore, any value greater than 1,024 bytes that is specified is ignored when connection is established with UNIX Software Distribution version 01-09 or earlier.

(5) Specify multiple network adapters

Select the Specify multiple network adapters check box in you wish to specify a priority order for the communications lines used by JP1/Software Distribution in an environment in which there are multiple network adapters (multiple LAN connections). This item is not displayed when setup information is created in an installation set.

Clicking the Network Adapter Settings button displays the Network Adapter Settings dialog box.

Select this option if you normally use one network as your first priority but want to switch to a network with a second or lower priority in the event of a network failure or when the networks used by JP1/Software Distribution are restricted.

The Network Adapter Settings button is disabled in the following cases:

When there is only one network adapter
When dial-up connection is specified.

Figure 6-7 Network Adapter Settings dialog box

Specify the priority in which network adapters should be used: Select this check box to specify priorities for using the network adapters when there are multiple network adapters. The default is that this check box is not selected.

Network Adapters

The following items are listed:

Network adapter^#
MAC address
IP address
Subnet mask

#: The number in square brackets is the binding order set by Windows. However, depending on the Windows version, it may not actually be the binding order.

Select the check boxes to specify the network adapters to be used by JP1/Software Distribution. If you select multiple network adapters, they are listed in descending order of priority. If you select only one network adapter check box, it is selected as the network adapter dedicated to JP1/Software Distribution. The system ignores an unsupported network adapter, if selected.

To change the priority order, select the network adapter you wish to change and use the Up or Down button to move it.

If multiple IP addresses are assigned to one network adapter, only the last assigned IP address is listed under Network Adapters and only that address can be used by JP1/Software Distribution.

Use as Client IP address: Select this check box if you wish to send to the higher system the IP address of the network adapter that is used according to the priority settings as the client's IP address. The default is that this check box is cleared, in which case the IP address of the network adapter that has the highest priority order is sent to the higher system in the binding order set by Windows. Note that the system ignores a network adapter whose IP address is 0.0.0.0.

Note: It is recommended that host names be used as the node identification key when selecting Specify the priority in which network adapters should be used. If you use IP addresses as the node identification key, they can be used also with the host IDs, but the IP addresses displayed by the Remote Installation Manager of the higher system may differ from the IP addresses specified in Network Adapters. If you select the Use as Client IP address check box, the IP addresses specified in Network Adapters are sent to the higher system and displayed by the Remote Installation Manager.
