1. 登录服务器
打开Windows自带应用程序PowerShell(注:学院机房电脑上PowerShell没装SSH,那么直接使用PuTTY,见本文第三部分),使用SSH协议远程登录服务器,命令为ssh username@host
,其中,
- 用户名
username
:u学号
- 主机
host
:os.suqiankun.com - 初始密码:学号
举例:
$ ssh u202021121004@os.suqiankun.com
u202021121004@os.suqiankun.com's password:

注:
- 出于安全考虑,Linux对密码没有回显
****
,不用慌,正确输入密码,按回车即可 - 没有PowerShell,用Windows命令终端cmd也行,按Win+R,输入cmd,回车便可打开cmd
常见错误
明明输入正确的密码,却还提示拒绝访问,如下:
$ ssh ubuntu@os.suqiankun.com
ubuntu@os.suqiankun.com's password:
Permission denied, please try again.
导致原因是ssh
与username
之间的空格是全角空格(在中文输入法下输入空格),换成半角空格,在英文输入法下输入空格。
2. 修改密码
使用命令passwd
修改密码。
$ passwd
Changing password for u202021121004.
Current password:
New password:
Retype new password:
3. 更好用的SSH终端
(1)PuTTY
PuTTY,免费,轻量级。下载PuTTY,安装,打开,填入主机名,点击Open即可,如下图。
按提示输入用户名和密码,便可登录。

(2)MobaXterm
MobaXterm,用SSH登录服务器,MobaXterm提供图形化SFTP浏览器,可以远程修改服务器上的文件。
(3)SecureCRT
SecureCRT,最好用,但收费。
