udb brodcast

[pma]

I'd like to have a application that is both server and client, if the application starts, it checks if another instance of this application is running on another server on the same LAN, if so it should send back some indification message. So I suppose I've to send a udb-broadcast with the server-part of the application, the other instance receives this braodcast with it's own server part and send's back a message to the other instance with the client part. Maybe someone can give a link to a source code sample :confused: Thank you Mario
