Manjaro 安装netcat---nc网络检测工具

在其他发行版上默认nc都有安装,或者通过apt或dnf等都可以安装使用,而在Manajaro上,通过软件包管理器搜索安装netcat会出现失败报错,于是只能通过git下载,构建本地AUR包才能正常完成安装

• git下载

git https://aur.archlinux.org/libressl-netcat.git

[jay@jay-pc ~]$ git clone https://aur.archlinux.org/libressl-netcat.git

• 进入到libressl-netcat目录,执行makepkg

• 构建完成后,生成本地软件包libressl-netcat-2.8.3-2-x86_64.pkg.tar.xz

ls -l

• 通过软件包管理器安装这个软件包,安装成功后就可以直接在shell执行nc工具命令了

libressl-netcat]$ nc
