In this Tutorial I will show how to use SFTP protocol to transfer the File From your OS to PLCNEXT CPU inside.(WinSCP is used in this case)
Please use your username and password on the PLCNEXT devices to login .
User name: admin
Password: Print on CPU.
By default, the system is not allowed to login as Root,but we still need to use root permission to move some files.
Please delete the root password after you finished the operation.

Drop Files
Drop your file from the Local OS to PLC NEXT CPU inside.
There are some advanced settings for the Transfer settings, but in this case default is used.
Permission denied error is shown because we do not have the right permission.

System will load the configuration file while the OpennSSH Server is started. The Path is /etc/ssh/sshd _ config and we need to edit it.
Backup
Backup it before you edit the configuration file.
Use this Command to copy the sshd_config file.
| cp sshd_config sshd_config_Bk |
edit
Use the Nano Editor to open the ssdh_config file.
| nano ssdh_config |
ssdh_config is opened.
Serch this Item: # Authentication: and Find #PermitRootLogin yes.
Delete the # character.
