本文介绍如何在Ubuntu系统中配置SSH服务以实现无密码登录。主要步骤包括安装openssh-server，修改sshd_config文件允许空密码登录，调整PAM配置，并重启SSH服务。此外还提供了创建无密码用户的命令。
ubuntu
- . sudo apt-get install openssh-server
- sudo gedit /etc/ssh/sshd_config modify as follow PermitEmptyPasswords yes
- sudo sed -i 's/nullok_secure/nullok/' /etc/pam.d/common-auth
- sudo service ssh restart
One more thing that I need to remind is that you have to create a user without password
you can use this command to delete the password of a account to make it empty
sudo adduser xxxx
sudo passwd -d xxxx
