服务器防火墙问题

今天，我联系了我的提供商后，我的网站突然无法打开，他们告诉我应该在 SSH 上输入：service iptables stop 命令，问题是我的 SSH 无法像往常一样建立，所以我想我应该使用我在 VPS 面板上创建的临时会话，这个会话将在 1349 端口上工作，所以当我尝试使用会话登录信息连接时，输入密码后，putty 开始显示大量如下命令：

似乎永远没有完成！我该如何解决这个问题？

答案1

这是内核发送有关 iptables 阻止数据包的信息。负责在命令行上输出的是系统记录器。由于您没有告诉我们您的系统上安装了哪个发行版，我只能猜测如何停止记录器：

service syslog stop
service syslog-ng stop
service rsyslog stop
