3.4.4 Connection settings when the name of the higher system cannot be resolved

In an environment that uses host names as the ID key for operations, a computer could lose the ability to access the DNS server due to quarantining or other actions. This means the agent would no longer be able to resolve the name of the connection-target higher system. In this situation, the agent can resolve the name from the IP address in the communications protocol when it receives an execution request from the higher system. If the network environment does not allow the agent to resolve the name of the connection-target higher system, the agent can use this approach to poll for jobs and send device information to the higher system. During this time, the agent will recognize the higher system that sends the execution request as its connection target.

To use this function, the Use the received IP address for connections with higher systems check box must be selected under Communication protocol for receiving execution requests on the Communication settings page of the agent configurations.

When you enable this function, a file for higher system addresses is automatically created on the managed computer when an execution request is received from a higher system. This file contains the mappings between IP addresses and host names of the higher systems. From that point onward, the managed computer uses the information in this file to resolve the host names of higher systems.

Under most circumstances, you do not need to edit the file for higher system addresses. However, in an environment in which the name of the higher system cannot be resolved, you need to create the file before deploying a computer that uses host names to access higher systems.

For details about the settings you need to use when deploying a computer that uses host names in an environment where the name of the higher system cannot be resolved, see 3.4.4(1) Settings for deploying a new managed computer in an environment where the name of the higher system cannot be resolved. For details about the format of the file for higher system addresses, see 3.4.4(2) Format of file for higher system addresses.

Notes:

You do not need to specify these settings in environments where IP addresses are used as the ID key for operations.
If the higher system is a cluster system, the managed computer might not be able to establish a connection.

Organization of this subsection

(1) Settings for deploying a new managed computer in an environment where the name of the higher system cannot be resolved
(2) Format of file for higher system addresses

(1) Settings for deploying a new managed computer in an environment where the name of the higher system cannot be resolved

If you deploy a computer that uses host names as the ID key for operations in an environment in which the name of the higher system cannot be resolved, the computer cannot connect to a higher system. This prevents the system from recognizing the computer as a destination. In this situation, you need to create a file for higher system addresses in advance, and use the following method to place the file on the managed computer.

Placing the file for higher system addresses on the managed computer after installing the agent software:

After installing the agent software, place the file for higher system addresses in the following folder:

JP1/IT Desktop Management 2 - Agent-installation-directory\MASTER\DB

When you restart the computer after finishing setup, the computer connects to a higher system based on the contents of the file for higher system addresses.

(2) Format of file for higher system addresses

You can enter mappings for multiple connection destinations in the file for higher system addresses. The managed computer connects to higher systems using the IP addresses that correspond to the host names in the file.

The file format is as follows:

File name:

SERVERIP.ini

Format:

[host-name]
IPaddress=IP-address
[#-filecheck]
key=Programcheck

Description:

host-name: Specify the host name of a connection destination of the managed computer. Host names are not case sensitive. If you specify the same host name more than once, the first appearance is valid.
IP-address: Specify the IP address that corresponds to the host name.

You can specify multiple combinations of host name and IP address.

Example:

The following is an example of a file for higher system addresses:

[host001]
IPaddress=10.100.100.20
[host005]
IPaddress=10.100.100.15
[host007]
IPaddress=10.100.100.57
[#-filecheck]
key=Programcheck

Note the following when creating a file for higher system addresses:

If an attempt to connect to an IP address results in an error, the pairing of host name and IP address that caused the error are deleted from the file.
If you delete the [#-filecheck] line from the file, the file for higher system addresses will be deleted.
The contents of the file for higher system addresses must consist of single-byte alphanumeric characters.
