PageSentry 4.0 Watches From Mac OS X -- Maxum Development has released the latest version of their server monitoring and management utility. In short, PageSentry constantly monitors an Internet server and performs some action (sends you email, pages you, runs an AppleScript script) should the server fail to respond. (I'm currently using an older version to reboot my IPNetRouter Mac automatically every few hours when one of its Ethernet cards freaks out and loses track of the Internet connection.) PageSentry 4.0 now comes in both Carbon and Classic versions for compatibility with System 7.1 through Mac OS X. New features include enhanced statistics, additional details in the Status window, sorting of sentries, the capability to suspend testing at specific times, and improved Web reporting. PageSentry 4.0 comes in 4 versions that allow varying numbers of sentries, ranging from the $95 PageSentry OneSite (5 sentries) to the $595 PageSentry ISP (500 sentries). [ACE]
Option-Click AirPort Menu for Network Details
If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.
