本文详细介绍了如何实现从本地Linux服务器B(10.10.17.47)无密码登录远程服务器A(10.10.17.206)的mosftpuser用户。步骤包括生成密钥文件、复制公钥、配置服务器以接受公钥认证，最后测试连接确保无密码登录成功。
You can manually set up password-free SSH for the mosftpuser user.
remote server A 10.10.17.206
local server B 10.10.17.47
we need to login to remote server without inputing password.
Step 1 Generate key files.
Log in to an sftp client 10.10.17.47 as the root user and run the following commands:
#ssh-keygen -t rsa -N "" -f $HOME/.ssh/id_rsa
Step 2 Copy the public key to sftp server.
Login to remote server as mosftpuser user and create .ssh directory for public key.
#mkdir -p ~/.ssh && touch ~/.ssh/authorized_keys
#chmod 700 ~/.ssh && chmod 600 ~/.ssh/authorized_keys
Login to sftp client server as root user
#scp ~/.ssh/id_rsa.pub sftpuser@10.10.17.206:~/.ssh/authorized_keys
Or you can use others tool winscp to finishe the duplication.
