It could be useful to set up a SSH server on your Linux box.
For instance, once set up, you can copy files from a Windows machine to your Linux box using ssh/ftp protocol.
It is actually quite easy. Here, we will consider a Fedora box.
The first step is to check whether the openssh-server is installed on your Fedora system. To do so execute the following command
sudo dnf install openssh-server
Next step is to enable systemd service sshd to make sure that SSH daemon will start after the reboot:
sudo systemctl enable sshd
Finally, start the ssh service (old way):
sudo service ssh start
For newer version of Linux:
sudo systemctl start sshd
