    SYN_SENT to Anonymous ports

    William Dobracki Newbie

      Running JBoss 3.2.6 on Windows behind a firewall.

      I am seeing JBoss actively try to establish connections with a SYN_SENT on two ports. The ports change each time the server is started.

      I would like to determine which services are trying to connect and either turn them off or set the ports. The application is running normally but the server.log shows two Exceptions which may or may not be relevent:

      ... 5 more

      Also, the rmi-il-service and the snmp agent are not deployed.

      Is there a way to drill down to which services are trying make the unwanted attempts to establish connections?
