问题描述

我知道这是一个简单的问题，但是如何在 ubuntu 中切换到 netcat-traditional ?每当我编写 netcat -h 时，似乎我正在运行 netcat-openbsd ?我是 Ubuntu 的新手，所以确切的命令会有所帮助.谢谢

I know this is a simple question, but how do I switch to netcat-traditional in ubuntu? Whenever I write netcat -h it appears that I am running netcat-openbsd instead? I'm new to Ubuntu so exact commands would be helpful. Thanks

推荐答案

1. 启用 Universe 存储库(如果未启用)

1. enable universe repository (if not enabled)

sudo add-apt-repository universe

使用突触安装另一个 netcat.(为此，必须启用 Universe 存储库.)

Install the other netcat using synaptic. (To do this, the universe repository must be enabled.)

sudo apt-get install netcat-traditional

输入 sudo update-alternatives --config nc

选择选项/bin/nc.traditional

输入 nc -h

输出:

[v1.10-38]
connect to somewhere:   nc [-options] hostname port[s] [ports] ...
listen for inbound: nc -l -p port [-options] [hostname] [port]
options:
    -c shell commands   as `-e'; use /bin/sh to exec [dangerous!!]
    -e filename     program to exec after connect [dangerous!!]
...
