1. Check whether the account password is wrong

 Go to VMware to verify whether the account password is correct, enter the command su, and enter the password to verify

su

Verify that the password is correct.

If the password is incorrect and needs to be reset:

重设root密码，sudo passwd root , 输入密码（我设置的是跟平时切换root的密码一致）

Enter su to verify that the setup is successful: 

 2. Check whether port 22 exists

ss -ntl

 Detect port already exists

3. Change the password to deny remote access and change the configuration (if there is no vim, install vim first)

 root@ubuntu:~# vim /etc/ssh/sshd_config

permitRootLogin prohibit-password

Change to PermitRootLogin yes

Restart the ssh service

systemctl restart ssh　　//重启ssh服务

4. Reconnect Mobaxterm
