Hi Diago, You are trying to send a packet to the port you are trying to listen on. As long as there is another process bound to that port (the snmp service of your OS), this will fail.
You will have to use a different listen address (e.g. "udp:0.0.0.0/0") to make this working. Regards, Frank Diogo Vasconcellos wrote:
Hi, I'm using SNMP4J v 1.9.3c, and every time I run my code I'm getting a java.net.BindException: Address already in use: Cannot bind. The weird thing is that yesterday it ran OK when querying 127.0.0.1/161. I'm using Windows XP, and its own SNMP service. How could I solve that, or find the answer? What am I doing wrong? Here's my code (the SNMP part) public static String testaOID (String endereco, String oid, String community) { String resultado = null; // PDU. PDU pdu = new PDU(); pdu.add(new VariableBinding(new OID(oid))); // sysDescr pdu.setType(PDU.GETNEXT); // Target CommunityTarget target = new CommunityTarget(); target.setCommunity(new OctetString(community)); target.setAddress(new UdpAddress(endereco)); target.setVersion(SnmpConstants.version2c); System.out.println(target.toString()); ResponseEvent response = null; Snmp snmp = null; // connection try { // SNMP instance snmp = new Snmp ( new DefaultUdpTransportMapping (new UdpAddress(endereco) ) ); System.out.println(snmp.toString()); snmp.listen(); } catch (Exception e) { System.out.println("1 - "+e.toString()); } try { response = snmp.send(pdu, target); } catch ( Exception e ) { System.out.println("2 - "+e.toString()); } try { // timeout... if (response.getResponse() == null) { System.out.println("TIMEOUT"); } else { // returns response System.out.println("Received response from: "+ response.getPeerAddress()); // dump response PDU resultado = response.getResponse().toString(); } } catch ( Exception e) { System.out.println("3 - "+e.toString()); } // returns response return resultado; } Sincere thanks, Diogo Vasconcellos _______________________________________________ SNMP4J mailing list SNMP4J@agentpp.org http://lists.agentpp.org/mailman/listinfo/snmp4j
