You can use HSTracker to wake, ping and remote control computers and other devices from the Hardware windows.
Wake
In detail view click the Wake button to wake the device. This only works for devices that support Wake-On-Lan and only if HSTracker and the target device are on the same physical ethernet network. VPN and wireless connections are not supported. To wake several devices switch to list view, select the devices while holding down cmd and click the Wake button at the bottom of the window. HSTracker also attempts to ping each device after waking it.
This feature requires an ethernet MAC address in the format nn:nn:nn:nn:nn:nn
Ping
Click the Ping button to check if the device is online. The result of the ping is displayed in the button itself. Point the mouse at the button and wait to reveal more information about the last test.
You can ping multiple devices from the list view. Select the devices while holding down cmd and click the Ping button at the bottom of the window.
This feature requires a primary IP address.
HTTP
Many network devices like routers and printers support control via a built-in web server. Use the HTTP button to connect to the device using a web browser. If your device requires a connection on a non-standard port just add it to the address in the format ip:port (192.168.1.1:8080 for example).
Hold down the alt key while clicking the HTTP button to use https instead.

Screen Sharing
Using the built-in VNC software in Mac OS X 10.5, HSTracker lets you remote control a computer directly from the application. Click the Remote Control button to connect directly to the computer's screen to observe it or remote control it. This requires that Remote Management on the target machine is enabled under System Preferences: Sharing.
