Simply cannot get SNMP working on SRX240

Hi guys,

Hope you can help me, after many attempts to get SNMP working I am turning to you for some help.

My config looks like this:

 security-zone Trust {
            description "Trusted Zone ";
            host-inbound-traffic {
                system-services {
                    all;
                    snmp;
                }
                protocols {
                    all;
                }
            }
            interfaces {
                ge-0/0/4.0 {
                    host-inbound-traffic {
                        system-services {
                            all;
                        }
                        protocols {
                            all;
                        }
                    }
                }
            }

forwarding-options {
    sampling {
        input {
            rate 100;
        }
        family inet {
            output {
                flow-server 192.168.1.71 {
                    port 2055;
                    version 5;
                }
            }
        }
    }
}

snmp {
name SRX;
description "FIREWALL";
location unk;
contact "test@test.com";
community public {
authorization read-only;
}
community "password" {
authorization read-write;
}
trap-group missingsmth-trap {

}
targets {
192.168.1.71;
}
}
traceoptions {

flag all;
}
}

Hope you guys can help
