Bchecker (Buddy Checker) is a novel P2P function for monitoring the accessibility of your web site. Using P2P the program will search for other peers which have activated the Bchecker function and will register your web server for monitoring. The buddy will continously check the accessibility of your web server. An alert mail will be generated if your site is not accessible. Your program will continously check that the buddy is monitoring your site. If your buddy goes down the program will search for a new buddy.
This function uses the Jxta public network. The sun jxta rendezvous servers operate on port 9700 or 9710. Check that at least 9700 is free and open.
