Wake-On-LAN
This function sends the Magic Packet frames to targets that support Wake-On-LAN (WOL) technology and then "power on" them. With this feature, you can turn on your individual PC or the PCs that located on LAN, another subnet or WAN. Also you can schedule a WOL task to run at specified time only once or periodically. From version 1.45 on, a service for Wake-On-LAN was available, meaning that you can schedule Wake-On-LAN tasks without login. From v1.50 on, you can perform Wake-On-LAN from the command line, meaning that tasks can be scheduled with Windows Tasks Scheduler.
General
Select "Tools>Wake-On-LAN" from the menu bar to make the Wake-On-LAN dialog visible. The names and MAC addresses of the selected machine in the main window would appear in Wake-On-LAN dialog. IP broadcast address is automatically set to "255.255.255.255". The default IP broadcast address "255.255.255.255" is the limited broadcast address that only reaches nodes on LAN. If the target is located on other subnet, you should set it to a directed broadcast address or unicast address. For example, specify directed broadcast address 192.168.10.255 to reach all nodes on the 192.168.10.x subnet. You can also directly use the IP address or DNS name of the remote machine. For example, "192.168.10.255" is a directed broadcast address, "121.47.135.23" and "amachine.aplace.com" are unicast addresses.
- Add
Manually add a new target. Require specifying the name, IP broadcast address and MAC address.
- Edit
Modify IP broadcast address or MAC address.
- Delete
Delete selected items from the list.
- Save
Save all items to a text file so you can load it later.
- Load
Load items from a text file.
- IP broadcast address settings
This allows you to set IP broadcast address of all targets in the list more conveniently.
- Get MAC addresses from router, switch or modem
This feature allows you to obtain MAC & IP addresses of machines from router, switch or modem, if those devices support SNMP MIB-2 and have an IP address. Generally you can get the addresses from the gateway. The results include off-line machines' data which saved in the device's cache.
- Wakeup
Send WOL commands to all targets immediately. The remote machine will be powered on as if the power button had been pressed.
Schedule
The maximum number of the tasks scheduling at the same time is 16. Exiting the program will cause all the tasks to stop scheduling, if they are scheduling in the program. But they will automatically resume scheduling next time the program run.
- Schedule
Schedule a new task to perform periodically at a later time and/or date. There are 4 schedule modes available presently.
- Daily
Under this mode task runs everyday. Require specifying start date. The end date is optional.
- Weekly
Require specifying start date and week days. The end date is optional. If Run Periodically check box is selected, the task runs on every specified day or days of the week. Otherwise the task runs only once on every specified day or days of the week.
- Monthly
Require specifying start date and month days. The end date is optional. If Run Periodically check box is selected, the task runs on every specified day or days of the month, on every specified month. Otherwise the task runs only once on every specified day or days of the month.
- Run once
Under this mode task only runs once.
- Start time
Specify the start time of the task.
- Submit
Submit a new task to schedule in LanHelper or service. Generally a new task is scheduled in LanHelper unless Service tab has been set.
Task List
All scheduling tasks are shown in this field. In the list it shows some task information such as computers number, start time, start date, end date, run days, last run time, submit time.
- Refresh
List all the tasks scheduling in LanHelper or in service.
- Detail
Show you the selected task's detailed information in General tab and Schedule tab.
- Remove
Delete the selected tasks.
Service
By using LanHelper service, you can schedule your Wake-On-LAN tasks more convenient, need not run LanHelper or login into Windows. While service is running, all performance results will be logged to Windows event log.
- Install service
Install the service before you use it.
- Uninstall service
Uninstall the service.
- Start service
Click this button to start the service after it has been installed. Once the service is started, tasks will be scheduled in service.
- Stop service
Stop the service. Tasks will then be scheduled in LanHelper.
- Submit new task into service
Turn on this option (check the check box) if you intend to schedule a new task in service. While service is running and this option is turned on, new tasks will be transferred to and be scheduled in the service. To schedule tasks in LanHelper or remove existing tasks, stop the service.
Notes:
A remote machine must meet some expectations so Wake-On-LAN can work. The motherboard and network adapter of the remote machine both support Wake-On-LAN technology, and connect a 3-pin power cable from network adapter to motherboard WOL connector (This step can be skipped if the motherboard is equipped with PCI 2.2 compliant bus). The Wake-On-LAN option in motherboard BIOS setup must be enabled, for Award BIOS checking the Power Management Setup for this option. The ATX power supply provides at least 600mA standby current. However, Wake-On-LAN may fail if the target computer was shut down improperly or hibernated last time. The reason is that some network cards require a flag to be set, which only happens when the operating system properly power down the machine.
