通过抓包可以发现，当服务端的端口没有打开时，服务端的系统向客户端返回 icmp ECONNREFUSED 报文，表明该连接异常。...(上面是 udp 异常下的 icmp，下面是正常 icmp) 当 UDP 连接异常时，可以通过 tcpdump 工具指定 ICMP 协议来抓取该异常报文，毕竟对方是通过 icmp 返回的 ECONNREFUSED...因为 nc 默认的探测逻辑很简单，只要在 2 秒钟内没有收到 icmp ECONNREFUSED 异常报文，那么就认为 UDP 连接成功。 下面是 nc udp 命令执行的过程。...setsockopt(3, SOL_SOCKET, SO_BROADCAST, [1], 4) = 0 connect(3, {sa_family=AF_INET, sin_port=htons(30000...udp 本就无握手的过程，他的 udp connect() 也只是在本地创建 socket 信息。在服务端使用 netstat 是看不到 udp 五元组的 socket。

建立连接（connect ）这一阶段发生在 connect 连接中。...在 libevent 中，为这些需要忽略的 errno 定义了宏 EVUTIL_ERR_CONNECT_RETRIABLE，宏里定义了上面三个需要忽略的信号，在 connect 处理时会判断如果遇到这些信号则进行忽略.../* True iff e is an error that means a connect can be retried....非阻塞模式下可以继续尝试读写ECONNRESET 或 EPIPE：表示连接被重置或对端关闭了连接，需要重新建立连接ENOTCONN：表示连接未建立或已断开，需要重新建立连接ETIMEDOUT：表示连接超时，需要重新建立连接ECONNREFUSED...在接受连接、建立连接和连接读写阶段可能会遇到多种 errno，如 EINTR、EAGAIN、EWOULDBLOCK、ECONNRESET、EPIPE、ENOTCONN、ETIMEDOUT、ECONNREFUSED
