What you are looking for is a 'heartbeat' service. Even this relies on the fact that you have to maintain a conversation between two servers. If either goes silent or is disconnected there is no way to figure it out until one of the ends tries a communication and it fails.
The best solution is for the client to be in charge of maintaining the connection, being able to recover when it determines it has been disconnected. I wrote an AOLserver client which maintained a connection to a Jabber server. If I restarted the Jabber server, my client would keep trying to connect until it succeeded. tom jackson -- AOLserver - http://www.aolserver.com/ To Remove yourself from this list, simply send an email to <[EMAIL PROTECTED]> with the body of "SIGNOFF AOLSERVER" in the email message.
