Hi Stan,
Artemis supports interceptors[1] to intercept packets entering and exiting
the server. This allows custom code to be executed, e.g. for auditing
packets, filtering or other reasons. So you could use an MQTTInterceptor[2]
to reject connection messages with admin username.
An example of MQTTInterceptor to clarify what I mean:
public class MQTTAdminRejectingInterceptor implements MQTTInterceptor {
@Override
public boolean intercept(final MqttMessage packet, RemotingConnection
connection) {
if (packet instanceof MqttConnectMessage &&
((MqttConnectMessage)packet).payload().userName().compareTo("admin") == 0) {
return false;
} else {
return true;
}
}
}
