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:17.10devops@ubuntu:~$ cat /etc/issueUbuntu 17.10  ldevops@ubuntu:~$ devops@ubuntu:~$ lsb_release -aNo LSB modules are available.Distributor ID: UbuntuDescription:  Ubuntu 17.10Release:  17.10Codename:  artfuldevops@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
