snmp4j发送v3trap

最近在做snmp的trapV3模拟发送，网上看到的大多数博客没有太详细的介绍，自己瞎摸索了一下

 

NoAuthNoPriv方式就像名称一样，无验证也无加密

   public void sendSnmpV3WithNoAuthNoPriv(Snmp snmp, Address targetAddr) {
  SNMP4JSettings.setExtensibilityEnabled(true);  SecurityProtocols.getInstance().addDefaultProtocols();  UserTarget userTarget = new UserTarget();  DefaultUdpTransportMapping udpTransportMap = null;  try {   udpTransportMap = new DefaultUdpTransportMapping();  }catch (Exception e) {   e.printStackTrace();  }  //engingId可用于进一步做trap的细分和验证，接收时可以不验证  byte[] enginId = MPv3.createLocalEngineID();  USM v3Usm = new USM(SecurityProtocols.getInstance(), new OctetString(enginId), 500);  SecurityModels securityModels = SecurityModels.getInstance();  securityModels.addSecurityModel(v3Usm);  userTarget.setRetries(2);  userTarget.setTimeout(3000);  userTarget.setVersion(SnmpConstants.version3);  userTarget.setSecurityLevel(SecurityLevel.NOAUTH_NOPRIV);  userTarget.setAddress(targetAddr);  //NOAUTH_NOPRIV和v1，v2c类似，可以直接接收，不验证SecurityName  //userTarget.setSecurityName(new OctetString("snmpV3TestUser"));  ScopedPDU v3pdu = new ScopedPDU();  v3pdu.add(new VariableBinding(SnmpConstants.sysDescr,new OctetString("what's wrong中文测试！")));  snmp.setLocalEngine(enginId, 500, 1);  try {   ResponseEvent response = snmp.send(v3pdu, userTarget);   if (response.getRequest() == null) {    // request timed out    System.out.println("no response");   } else {    System.out.println("Received response from: "      + response.getSource());    // dump response PDU    System.out.println(response.getRequest().toString());    //显示发送的信息状态。   }  }catch (Exception e) {   e.printStackTrace();  }  

AUTH_NOPRIV会验证SecurityName，authenticationPass，对于privacyPassp的正确性不会验证

public void sendSnmpV3WithAuthAndPriv(Snmp snmp, Address targetAddr) {  OctetString securityName = new OctetString("securityName");  OctetString passWord = new OctetString("snmpV3TestPassword");  OctetString privStr = new OctetString("snmpV3TestPriv");  SNMP4JSettings.setExtensibilityEnabled(true);  byte[] enginId = "TEO_ID".getBytes();  USM v3Usm = new USM(SecurityProtocols.getInstance(), new OctetString(enginId), 500);  SecurityProtocols.getInstance().addDefaultProtocols();  UserTarget userTarget = new UserTarget();  userTarget.setVersion(SnmpConstants.version3);  userTarget.setSecurityLevel(SecurityLevel.AUTH_NOPRIV);  userTarget.setAddress(targetAddr);  userTarget.setSecurityName(securityName);  userTarget.setRetries(2);  userTarget.setTimeout(3000);  SecurityModels securityModels = SecurityModels.getInstance();  securityModels.addSecurityModel(v3Usm);
　　　　　//此处五个参数分别为securityName，authentication密码加密，
  //authenticationPassphrase，privacyPass加密方式，privacyPassphrase

  snmp.getUSM().addUser(securityName, new UsmUser(securityName, AuthMD5.ID, passWord, PrivDES.ID, privStr)); 
  ScopedPDU v3pdu = new ScopedPDU(); v3pdu.setType(PDU.NOTIFICATION);
  v3pdu.add(new VariableBinding(SnmpConstants.sysDescr,new OctetString("what's wrong中文测试！"))); 
  snmp.setLocalEngine(enginId, 500, 1); 
  try { ResponseEvent response = snmp.send(v3pdu, userTarget); 
   if (response.getRequest() == null) { // request timed out System.out.println("no response"); } 
   else { System.out.println("Received response from: " + response.getSource()); // dump response PDU  
   System.out.println(response.getRequest().toString()); //显示发送的信息状态。  
   }  
  }catch (Exception e) 
  { e.printStackTrace(); } }

AUTH_PRIV则是会验证SecurityName，authenticationPass，privacyPass

public void sendSnmpV3WithAuthAndNoPriv(Snmp snmp, Address targetAddr) {  OctetString securityName = new OctetString("111222333");  OctetString passWord = new OctetString("111222555");  OctetString privStr = new OctetString("23152156");  SNMP4JSettings.setExtensibilityEnabled(true);  byte[] enginId = "TEO_ID".getBytes();  USM v3Usm = new USM(SecurityProtocols.getInstance(), new OctetString(enginId), 500);  SecurityProtocols.getInstance().addDefaultProtocols();  UserTarget userTarget = new UserTarget();  userTarget.setVersion(SnmpConstants.version3);  userTarget.setSecurityLevel(SecurityLevel.AUTH_NOPRIV);  userTarget.setAddress(targetAddr);  userTarget.setSecurityName(securityName);  userTarget.setRetries(2);  userTarget.setTimeout(3000);  SecurityModels securityModels = SecurityModels.getInstance();  securityModels.addSecurityModel(v3Usm);  snmp.getUSM().addUser(securityName, new UsmUser(securityName, AuthSHA.ID, passWord, PrivDES.ID,privStr));  ScopedPDU v3pdu = new ScopedPDU();  v3pdu.setType(PDU.NOTIFICATION);  v3pdu.add(new VariableBinding(SnmpConstants.sysDescr,new OctetString("what's wrong中文测试！")));  snmp.setLocalEngine(enginId, 500, 1);  try {   ResponseEvent response = snmp.send(v3pdu, userTarget);   if (response.getRequest() == null) {    // request timed out    System.out.println("no response");   } else {    System.out.println("Received response from: "      + response.getSource());    // dump response PDU    System.out.println(response.getRequest().toString());    //显示发送的信息状态。   }  }catch (Exception e) {   e.printStackTrace();  } }
