为NLB实例添加TCP监听

如果您需要在NLB实例上转发来自客户端的TCP协议请求，特别是在注重可靠性、对数据准确性要求高和速度可以相对较慢的场景中，如文件传输、发送或接收邮件和远程登录等，您可以为NLB实例添加一个TCP监听。

在Linux中，如何实时抓取并显示当前系统中tcp 80 端口的网络数据信息？

在Linux中，实时抓取并显示当前系统中TCP 80端口的网络数据信息，可以使用tcpdump这个强大的命令行工具。以下是详细的步骤和命令：打开终端：首先，打开一个具有足够权限的终端窗口。通常，需要使用sudo或以root身份执行tcpdump，因为它需要访问底层网络接口。确定网络接口：使用ifconfig（在某些新系统上可能是ip addr）命令列出网络接口，...

在电脑上测试TCP/UDP端口是否开放，还是得网络大佬这招厉害！

首先端口分 tcp、udp 之分，所以同一个端口号还有tcp 协议和 udp 协议之分。我们一般最常见的工具是 telnet，但是 telnet 使用的是 tcp 协议，换句话说 telnet 只能检测 tcp 的这个端口打开了没。当然除了电脑自带的telnet功能，我们也可以安装如tcping等测试端口的插件工具。电脑自带的telnet客户端功能默认关闭，可以通过如下步骤开...

修改TCP TIME-WAIT超时时间以提升网络性能

在Linux的内核中，TCP/IP协议的TIME-WAIT状态持续60秒且无法修改。在某些场景下（例如TCP负载过高时），适当调小该值有助于提升网络性能。因此Alibaba Cloud Linux 2（内核版本4.19.43-13.al7开始）和Alibaba Cloud Linux 3新增内核接口用于修改TCP TIME-WAIT状态持续时间，从而提升网络性能和资源的利用率。
