garder une connection active

Bonjour j'ai ecrit un code qui se connecte à un serveur. la connection réussie et le binding aussi. mais le probleme c'est que ça connecte et ce deconnecte automatiquement donc au niveau du serveur il n'y a aucune trace. je voudrais savoir comment maintenir la connection active et ecrire sur le serveur a partir de ma machine.
voila mon code
