K8s集群中Calico节点启动失败？手把手教你解决BIRDv4 socket连接问题本文深度解析Kubernetes集群中Calico节点因BIRDv4 socket连接失败而启动故障的根本原因。问题通常源于默认的IP自动检测机制（如first-found）在多网卡环境下选中了错误IP，导致BIRD路由进程无法启动。文章提供了从日志解读、IP检测验证到通过修改ConfigMap或Tigera Operator配置进行修复的完整实战方案，并强调了配置明确IP检测方法的重要性。阅读详情

我这里，采用while来不断连接，因为，该程序启动后只要不断电，就会一直运行，如果网络断了，就自动连接服务器，我测试过很多次，如果连接的次数多了的话，在执行connect(pcs->m_ServerSocket, (struct sockaddr *)&server, sizeof(struct sockaddr));时，就会卡起，求原因。。。。。。。。。。。。。。。
