useradd -g sftp_users -d /add -s /sbin/nologin USERNAME
The place USERNAME is the title of the person.
Subsequent, give the brand new person a password. This password would be the password the brand new customers use to log in with the sftp command. To arrange the password, difficulty the command:

The place USERNAME is the title of the brand new person you created above.
Configure sshd
Open up the SSH daemon configuration file with the command:
nano /and so on/ssh/sshd_config

The place USERNAME is the title of our new person and SERVER_IP is the IP deal with of our SFTP server. You’ll be prompted for USERNAME’s password. When you efficiently authenticate, you can be greeted with the sftp immediate. Sort pwd to examine the working path and it’s best to see /add as depicted within the picture beneath.
