2.2. Default Server and Agent Ports

As with other servers and services, JBoss ON servers and agents communicate with each other by connecting over system ports. JBoss ON uses ports for three types of connections:
  • Server to database communication
    The server has to be able to connect to its database. The database port number depends on both the type of database and the specific configuration for the database.
  • Server to agent communication
    The server connects to an agent over a single port configured for the agent. This port is used for both standard and SSL communications between the server and agent.
  • Agent to server communication
    An agent can talk to multiple JBoss ON servers, even if they use the same port (since each server is on a different host.) The agent will use either a standard port or an SSL port to connect to the JBoss ON server, depending on the connection (transport) method that is configured. The agent will only attempt to use a single port.


Servers do not talk to one another directly, so there are no ports for server-to-server links.
The default port numbers for JBoss ON connections are listed in Table 3, “Default JBoss ON Ports”. The port numbers can be changed for any of the JBoss ON services or different values can be used at installation.
