How to Setup SFTP Server on Fedora 40

To set up an SFTP server on Fedora 40, you need to configure SSH to allow SFTP connections.

Step 1 : Ensure that the sshd service is installed and running:

sudo systemctl status sshd

Step 2 : Edit the sshd configuration file to allow SFTP:

sudo nano /etc/ssh/sshd_config

Add or uncomment the following line:

Subsystem sftp internal-sftp

Match Group sftp
        ChrootDirectory %h
        X11Forwarding no
        AllowTcpForwarding no
        ForceCommand internal-sftp

Step 3 : Restart sshd

sudo systemctl restart sshd

Step 4 : Create an SFTP group

sudo groupadd sftp

Step 5 : Create an SFTP user

sudo adduser sftp_user

Step 6 : Set a password for the SFTP user

sudo passwd sftp_user

Step 7 : Assign the user to the SFTP group

sudo usermod -aG sftp sftp_user

Step 8 : Set the appropriate permissions for the directories users will access via SFTP.

sudo chown root:root /home/sftp_user
sudo chmod 755 /home/sftp_user
sudo mkdir /home/sftp_user/upload
sudo chown sftp_user:sftp_user /home/sftp_user/upload
sudo chmod 755 /home/sftp_user/upload

Step 9 : Restart SSH service

sudo systemctl restart sshd

Step 10 : Test the connection

- Open an SFTP client (e.g., FileZilla).

- Add a new site

• Enter the "Host" (IP address or domain name).
• Select "SFTP - SSH File Transfer Protocol".
• Set "Port" to 22.
• Choose "Normal" login type, and enter the username and password.

- Click "Connect".

Congratulations! You have successfully set up an SFTP server on Fedora 40.
