(编辑:jimmy 日期: 2024/11/28 浏览:3 次 )
记录一下Ubuntu17.10的openssh-server的安装和使用。安装之后就可以使用ssh登陆Ubuntu了,所以是Ubuntu的基础设定之一。
事前准备
Ubuntu版本:17.10 devops@ubuntu:~$ cat /etc/issue Ubuntu 17.10 \n \l devops@ubuntu:~$ devops@ubuntu:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 17.10 Release: 17.10 Codename: artful devops@ubuntu:~$
17.10的Ubuntu代号Artful Aardvark,于2017年10月19日正式发布,是更换GNOME的首个版本,但是这不是一个LTS版本,会支持到2018年8月,是2018年Ubuntu的LTS的版本之前的过渡版本。openssh-server的安装基本上对于Ubuntu的版本影响非常低,基本操作步骤大体一致。
安装步骤
按照如下安装步骤进行安装
操作日志
此处再以安装的状态下抓取的日志,apt install显示会有所不同

从终端进行ssh连接
