python tcp服务器centos7

我已经用Python2.7编写了一个小型tcp服务器。代码如下。 它部署在Centos 7上：

开始时，我收到错误Errno:104-Peer关闭了套接字连接。在wireshark中，所以我打开了目标端口 打开端口：/etc/sysconfig/iptables添加规则： -输入-m state-state NEW-ptcp-dport 5555-j ACCEPT 然后使用sudo systemctl restart iptables重新启动 我试着重新启动等'仍然得到错误 在wireshark中，打开端口后出现错误：

我的python脚本基于和，在日志中看不到任何内容。。好像连连接都没有完成

服务器套接字是在哪里创建的？谢谢你的重播，很抱歉我错过了。我更新了代码示例-服务器套接字是创建的第一件事。在selinux中打开端口有一点帮助：所有这些：semanage port-a-t http_port_t-p tcp 8088 semanage port-a-t http_port_t-p tcp 5555在centos 7中在/etc/sysconfig/iptables add下打开iptables中的端口：-a INPUT-m state-state NEW-p tcp-dport 8088-j ACCEPT-A INPUT-m state-state NEW-p tcp-dport 5555-j ACCEPT previus注释解决了部分问题：现在数据在大约2-3分钟的几次重试后到达之前的错误是：telnet:connect to address 192.168.1.104：发出时连接被拒绝：telnet 192.168.1.104 5555知道延迟的原因吗？创造了什么？[我相信这在我的python脚本中，但不知道我缺少了什么]
