Create SFTP User

Step 1 – Create User

First of all, create a user account to use for sftp access. Below command will create user named vinhnx with no shell access.

sudo adduser --shell /bin/false vinhnx

Step 2 – Create Directory for SFTP

Now, create the directory structure to be accessible by sftp user.

sudo mkdir -p /var/vinhnx/upload

Change the ownership of the files directory to sftp user. So that sftp user can read and write on this directory.

sudo chown vinhnx:vinhnx /var/vinhnx/upload

And set the owner and group owner of the /var/vinhnx to root. The root user has read/write access on this access. Group member and other account have only read and execute permissions.

sudo chown root:root /var/vinhnx
sudo chmod 755 /var/vinhnx

Step 3 – Configure SSH for SFTP Only

Now edit the SSH configuration file in a text editor

sudo vim /etc/ssh/sshd_config

and add the following settings at end of file.

Match User vinhnx
	ForceCommand internal-sftp
	PasswordAuthentication yes
	ChrootDirectory /var/vinhnx
	PermitTunnel no
	AllowAgentForwarding no
	AllowTcpForwarding no
	X11Forwarding no

Save the configuration and restart SSH service to apply changes.

sudo systemctl restart ssh
