Ubuntu服务器初始化

故意的 ubuntu 2004 server

#好像是这个成功的 有个要的 不要在kali root ssh ubuntu 
  ➜  ~ ssh [email protected]
Please login as the user "evan" rather than the user "root".

sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config
sed  -i   's/PasswordAuthentication no/PasswordAuthentication yes/' /etc/ssh/sshd_config
 sudo systemctl restart ssh

sed -i 's!#PermitRootLogin prohibit-password!PermitRootLogin yes!' /etc/ssh/sshd_config
 sed -i 's!#PermitRootLogin prohibit-password!PermitRootLogin yes!' /etc/ssh/sshd_config
  /etc/init.d/ssh restart 

问题就在这里了 把ssh-rsa前的del 120
