适用场景

  • NetApp SolidFire
  • NetApp HCI
  • NetApp Element 软件

问题描述

netcat (Linux中的"nc"命令)比telnet更有效地检查目标系统上的特定端口是否已打开。它速度更快、并可直接提供连接到端口成功或失败的信息。

NC基于TCP、在 不允许执行ping操作的环境中对网络连接进行故障排除(例如、验证网络端口要求)非常有用。

在Element软件环境 中、可以使用它来检查从mNode到各种集群管理IP、从mNode到ActiveIQ端点(monitoring.solidfire.com)以及存储网络上的IP之间的连接(后者需要NetApp支持部门的协助)。
