我正在尝试使用 telnet 连接服务器，但是当我输入 telnet localhost 8000 时，它显示 telnet not found 的错误。我用 C 编写了我的代码并在 macOS 终端上运行它。我应该先安装一些东西才能使用它吗？
1 个回答 正确答案
是的，您需要安装 telnet 才能在您的 Mac 上使用它。您也可以尝试使用预装在 macOS 机器上的替代工具。它被调用netcat，您可以执行以下操作：
nc -vz localhost 8000
如果上面的命令不够好，您可以按照可以在此处找到的教程在您的 Mac 上安装 telnet：

更准确地说，该部分标题为： Installing Telnet in MacOS with Homebrew
您需要安装 homebrew（它是 MacOS 的包管理器，类似于 linux 中的 yum 或 apt）。
I'm trying to connect the server using telnet, but when I enter telnet localhost 8000. It shows the error of telnet not found. I wrote my code in C and ran it on macOS terminal. Am I supposed to install something before I can use it?

telnetis a somewhat outdated standard program. Apparently you have to install it. For details how to install it on Linux you would have to tell your Linux distribution and version.

Yes you would need to install telnet to use it on your mac. You can also try using an alternative tool, that comes pre-installed on macOS machines. It is called netcat and you can do the following:
nc -vz localhost 8000
If the command above is not good enough, you can install telnet on your mac by following the tutorial that can be found here:

More precisely, the section titled: Installing Telnet in MacOS with Homebrew
You will need to install homebrew (it is a package manager for MacOS, similar to yum or apt in linux).
