mina：UDP server 收不到数据 The virtual circuit was reset by the remote side ......

Posted 2020-12-17 huiy

用mina做了一个UDP接收的程序，绑定的时候没有指定IP，只是指定了端口。

然后还是在本机连接127.0.0.1和UDP端口号，死活收不到数据。

用TCP/UDP工具发送数据，提示如下：

        The virtual circuit was reset by the remote side executing a hard or abortive close. The application should close the socket as it is no longer usable. On a UPD-datagram socket this error would indicate that a previous send operation resulted in an ICMP "Port Unreachable" message.

解决办法：

没有指定IP，就是默认0.0.0.0。

改为在具体的IP地址绑定，例如192.168.0.10，发现能收到数据。
