To execute a host search and detect hosts on which JP1/Software Distribution is not installed:

1. Display the Detection of Hosts Not Containing Software Distribution dialog box.
2. From the Detection of Hosts Not Containing Software Distribution dialog box, display the Host Search dialog box.
   You can execute a host search from the Host Search dialog box. For details about how to display and manipulate the Host Search dialog box, see (3) Manipulating the Host Search dialog box.
   
3. Set details for the host search.
   Host search is executed according to Host search settings that specify the range of the network to be searched and the search schedule. For details about how to specify the host search settings, see (4) Detailed host search settings.
   You can also set a validity period for the information about found hosts. For settings for the validity period of information about found hosts, see (5) Settings for the validity period of search results.
   
4. Execute the host search.
   For details about how to execute a host search, see (6) Executing a search.
   When the search is completed, hosts on which JP1/Software Distribution is not installed will have been detected automatically.
   
5. Display the detection results.
   Click the Latest information button in the Detection of Hosts Not Containing Software Distribution dialog box to display the detection results of hosts on which JP1/Software Distribution is not installed.
   

The following notes apply to detecting hosts on which JP1/Software Distribution is not installed:

• For a UNIX JP1/Software Distribution host that uses multiple network adapters, only one MAC address is registered in the managing server. Such a host is always detected as a host on which JP1/Software Distribution is not installed due to its other MAC addresses.
  You should handle this by specifying the hosts detected by the other MAC addresses as non-detection targets.
  
• If you are using a relay manager to detect hosts on which JP1/Software Distribution is not installed, execute the host search within the range of the system configuration that is managed by the relay manager. All hosts outside this range that are managed by the relay manager would be detected as non-Software Distribution hosts.
• If a new host is registered in the managing server by a facility for registering the system configuration automatically or by the reporting of system information while hosts on which JP1/Software Distribution is not installed are being detected, a newly registered host may be detected as a host on which JP1/Software Distribution is not installed. In such a case, re-execute detection from the Detect unintroduced host menu. Information about a host registered in the managing server is deleted from the detection results of hosts on which JP1/Software Distribution is not installed. To determine whether or not such a host has been registered correctly, compare the system configuration information in the managing server with the detection results of hosts on which JP1/Software Distribution is not installed.

During a host search, the system uses SNMP to search for hosts whose power is on within the range of IP addresses specified in the host search settings. The system does not search any host whose power is off.

During the host search, the system also acquires information about the hosts. You can manage this information for the hosts on which JP1/Software Distribution is not installed.

The host information that can be acquired depends on whether or not the detected hosts support SNMP. The following table shows the host information that can be acquired during a host search.

Table 9-4 Host information that can be acquired during a host search

Host information	Host supporting SNMP	Host not supporting SNMP
MAC address#1	Yes	Yes
IP address	Yes	Yes
Host name#2	Yes	Yes
Subnet mask#3	Yes	No
Node type#4	Yes	No
Description#3	Yes	No

Legend:

Yes: Can be acquired.

No: Cannot be acquired.

#1

Information can be acquired if the router supports SNMP.

#2

Information can be acquired if the host name can be resolved from the IP address.

#3

Information can be acquired if a value is set in MIB.

#4

If the type cannot be identified or the host does not support SNMP, Computer is set.

In the Host Search dialog box, you can execute the host search and add and change host search settings.

To execute a host search, you must specify host search settings, such as the IP address range in the network that is to be subject to the host search and the date and time the host search is to be executed.

You specify host search settings in the Addition of Host Search Setup dialog box. There are two ways to display the Addition of Host Search Setup dialog box:

• By clicking in the Host Search dialog box.
• By choosing Edit and then Add in the Host Search dialog box.

The following shows the Addition of Host Search Setup dialog box:

Figure 9-44 Addition of Host Search Setup dialog box

Search settings

Specifies a name for the host search settings and the network search range.

Name

Specifies a name for the host search settings, as 1-64 characters. Because you can set up multiple sets of host search settings, we recommend that you use a name that is easy to manage. This item is optional.

IP Address - start (mandatory)

Specifies the start IP address of the network range that is to be subject to this host search.

IP Address - exit (mandatory)

Specifies the end IP address of the network range that is to be subject to this host search.

Community name (mandatory)

Specifies the community name of SNMP that will be used in the host search, as 1-255 characters. The default is public.

You can register a maximum of ten community names for each set of host search settings.

To register a community name, click the Add button and then specify the community name. To change or delete a community name that is displayed in the Community name field, select the applicable community name and click the Change or Delete button.

Schedule settings

Selects whether the host search is to be executed immediately or at a specified date and time.

Immediate execution

If you select Immediate execution, clicking the Start after save button sets the host search settings and executes the host search immediately.

Scheduled execution

Executes the host search at a scheduled date and time.

If you select Monthly, select the host search execution date within each month from the Date pull-down list. If the specified date does not exist in a particular month, such as 31 specified in Date and the month is April, the host search will be executed on the last day of the month.

If you select Weekly, select from the Day pull-down list the day of the week on which the host search is to be executed every week.

Specify the host search execution time in the following range:

• Hour(s): 0 to 23
• Minute(s): 0 to 59

Options

Selects the method for acquiring host information.

Acquire the host name

Select this checkbox to acquire the host name in a host search. The default is that this check box is selected.

If the host names are not needed as part of the information about hosts on which JP1/Software Distribution is not installed, clear this check box; in such a case, the host search time may be reduced because name resolution is not performed.

In the case of hosts that support SNMP, their host names are acquired even when this check box is cleared.

Information acquisition range

Acquires hosts by searching on the basis of a range of host information. The default is Acquire information from the router.

Acquire information from the router

Acquires host information using SNMP for the hosts that were found from the router. Selecting this option is recommended.

Acquire information from all terminals

Acquires host information using SNMP for all the IP addresses specified as the search range. You should select this option when the search path includes a router that does not respond to SNMP, such as a VPN environment. Also select this option when the number of hosts resulting from selection of the Acquire information from the router option is too small for the actual number of hosts.

A search for hosts using this option may take some time because the system attempts to acquire host information even when there is no host with a specified IP address or from target hosts that are shut down (power off).

Check if started

When this check box is selected in conjunction with selection of the Acquire information from all terminals radio button, the system checks whether each host is active before attempting to acquire its host information.

If more than half the IP addresses specified within the search range are for hosts that are shut down or are addresses for which there is no corresponding host, selecting this check box may reduce the host search time.

You should make sure that this check box is not selected if the network search range includes any host that cannot use the ICMP port, such as a host whose OS is Windows XP Service Pack 2 or Windows Server 2003 Service Pack 1.

Save button

Sets the host search settings. The host search settings are displayed on the Host search settings page of the Host Search dialog box.

Start after save button

Sets the host search settings and starts the host search. If you have selected Immediate execution, clicking this button sets the host search settings and executes the host search immediately. If you have selected Scheduled execution, the host search is executed in accordance with the specified schedule date and time.

The host search settings are displayed on the Host search settings page of the Host Search dialog box.

Cancel button

Closes the Addition of Host Search Setup dialog box without saving the host search settings.

If the intended information is not obtained from a host, you can determine if it is simply because the host's power was off, or if the host has been removed from the network. You do this by setting a validity period for the search results.

If a search does not yield intended information from a host, that host is assumed at the completion of the host search to be nonexistent in the network as of the time of detection of hosts on which JP1/Software Distribution is not installed. In order to avoid this, you may set a validity period for the host information.

When a host search is executed after the specified validity period since the last host search has expired, any host that still does not yield intended information will be assumed to have been removed from the network and will no longer be detected as a host on which JP1/Software Distribution is not installed.

You set the validity period for search results in the Search Option dialog box, which is displayed by choosing Search and then Search Options.

Figure 9-45 Search Option dialog box

Validity period

Specifies the period for which the information about the searched hosts is to remain valid, in the range from 1 to 365 days. The default is 90 days.

To execute a host search, select the desired host search settings in the Host Search dialog box and then click the or Start button.

The host search begins and Running is displayed in the Status column.

When the host search is completed, the Status changes to Finish and any hosts on which JP1/Software Distribution is not installed will have been detected automatically.

Note that these detection results are not applied to the Detection of Hosts Not Containing Software Distribution dialog box. To display the detection results, you must click the Latest information button in the Detection of Hosts Not Containing Software Distribution dialog box to refresh the screen display.

To stop a host search, click the or Stop button. The Status changes to Cancel and the host search stops. When the host search is cancelled, the host information that has been obtained up to that point is registered in the managing server. However, detection of hosts on which JP1/Software Distribution is not installed is not executed.
