Ubuntu系統(tǒng)root用戶遠程登錄

通過CRT遠程登錄Ubuntu時遇到報錯：

The client has disconnected from the server. Reason:

Unable to authenticate using any of the configured authentication methods.

Ubuntu初始登錄只能是普通用戶，想用root登錄，需普通用戶登錄，然后切換為root用戶，先設(shè)置root密碼，再更改sshd_config文件

ixo@snort:~$ sudo su

Password:

root@snort:/home/ixo#sudo passwd root

New password:

Retype new password:

passwd: password updated successfully

root@snort:/home/ivo# nano /etc/ssh/sshd_config

注意：是sshd_config，而不是ssh_config

...

#port 22

port 22

#PermitRootLogin prohibit-password

PermitRootLogin yes # 允許root直接登錄

保存后重啟ssh服務(wù)

sudo service ssh restart
