For automatic shutdown to be applied to a system that was started by the client control facility, you must set the following information:

If requested by the administrator, shut down or restart the computer

On the Job Options page at setup, select If requested by the administrator, shut down or restart the computer.

You can specify this option only while you are setting up JP1/Software Distribution Client (client). This option is not available during setup of client facilities for JP1/Software Distribution Manager or JP1/Software Distribution Client (relay system) because relay managers and relay systems must always be running.

Max. number of subsystems in which jobs can execute concurrently

You will not be able to use client control to start the destination systems if 0 is specified for the following options when you set up a higher system to which clients are connected:

• For the central manager and relay manager: Max. number of subsystems in which jobs can execute concurrently on the Server Customization page in the Server Setup dialog box
• For a relay system: Max. number of relays or clients in which jobs can execute concurrently in the Relay System Setup dialog box

Automatically register this computer in the system configuration

If the system is using JP1/Software Distribution version 06-00 or later, select the Automatically register this computer in the system configuration setting.

Polling setting

We recommend that you select Client will poll the managing server for the polling setting.

The following subsections provide notes on the use of Wake on LAN to perform client control.

(a) Notes on the system configuration

If you use the client control facility in a system configuration in which a router is installed on the job route, you should use one of the network environments listed below. For security, environment 1 is recommended:

1. Place one or more relay managers or relay systems for each router and keep them always running. (Recommended)
2. Set the router so that it passes the packets with broadcast specified.
   In this environment, there is no need to place a relay manager or relay system for each router. However, in an environment where destination IP addresses are subnetted by routers, the following conditions must be satisfied:
   
   • The following is installed on each PC that is started by the client control facility: JP1/Software Distribution version 06-51 or later, and WMI.
   • Before using the client control facility, a Get system information from client job is executed to obtain subnet mask information.
   • On the Relay System Customization page of JP1/Software Distribution Client (relay system), the Record the system/software information answered from the lower clients option is selected.

If you set the router to pass the packets with broadcast specified, the system could be affected by Denial of Service (DoS) attacks. To avoid this, use environment 1.

(b) Notes on hardware

This section discusses hardware considerations when you use the client control facility.

• The client control facility is affected significantly by various settings and compatibilities among individual components. You can use the following provided command to determine whether a PC can be started by the client control facility:
  

  Command name

  magicsnd.exe

  Command storage location

  JP1/Software-Distribution-installation-directory\bin

  Usage

  magicsnd -a MAC-address [-m subnet-mask] IP-address

  Execute this command from the MS-DOS prompt. The command starts the specified destination. If this command cannot start a PC, the PC cannot be started by the client control facility.

  The subnet mask specification is required only if you have set up your router to pass packets for which broadcast was specified, in an environment in which destination IP addresses are subnetted by routers.

  Usage examples

  The following is an example of the command when a relay system that is always running is placed for each router:

  magicsnd -a 0000e2168066 172.17.11.145

  The following is an example of the command when IP addresses are subnetted and the routers pass packets with broadcast specified:

  magicsnd -a 0000e2168066 -m 255.255.255.0 172.17.11.145

• If there are any items relating to Wake on LAN in the BIOS settings, enable them.
• If HUB or NIC supports the LinkChange facility, turning on the power to equipment might start a PC in which Wake on LAN is enabled. To avoid this problem, the equipment must always be kept on or the LinkChange facility must be disabled.
• Three types of signals are produced by a LAN card: RWU-High, RWU-Low, and PME. Because the type of signal that can be used depends on the motherboard, it is necessary to set the jumper pins appropriately. For details about the pin settings, see the documentation from the LAN card supplier.

(c) Notes on startup

This section provides notes on using the client control facility to start clients.

• If you execute multiple jobs that use the client control facility and all the jobs are specified to start a client, after a destination client has been started, subsequent startup requests to the same destination client are ignored.
• Startup and shutdown are disabled if you use the client control facility to execute a job on a PC running a version of JP1/Software Distribution Client earlier than 06-00.
• The client control facility might not be able to start the system in an environment in which more than one network interface card is used on a single PC.
• When you execute a job from JP1/Software Distribution Manager or JP1/Software Distribution Client (relay system) for which Boot the client at the job destination has been specified, some PCs might freeze up during startup. This is because the startup intervals sent from the JP1/Software Distribution Manager or JP1/Software Distribution Client (relay system) are shorter than the startup time of the PC. If this occurs, change the following registry value for the JP1/Software Distribution Manager or JP1/Software Distribution Client (relay system) to a value greater than the startup time of the PC:
  

  Registry key:

  When the OS is the 32-bit version of JP1/Software Distribution Manager
