A Keyhole Watcher is a simple utility that will help network/system administrator monitor network server liveness. A Keyhole Watcher maintains a list of servers (defined with their IP address and port number) and checks each of them every N seconds by connecting/disconnecting the socket.
Our Review: A simple ip monitor. Keyhole Watcher pings the server or computer you specify and returns if it is alive or not. It can be configured to tell you if your server goes down, and when it comes back up again.
Great piece of freeware.
