To do this I used a program called SSHFS which has done a great job. First, install if from the repo
sudo apt-get install sshfs
You’ll need to create a directory to use as the location for your files
sudo mkdir /mnt/sshftps
Execute the command to connect the actual SFTP Server. Replace xxx.xxx with the target IP address and use the -p option to specify the connection port. The user parameter is your user name. The :/ at the end of the IP address indicates the end of the IP address. Don’t try to put the port number after the colon
sudo sshfs -o allow_other -p 6789 firstname.lastname@example.org:/ /mnt/sshftps
This will create a semi-permanent connection which will close if the machine is restarted. You can create a permanent connection which will reopen when the machine starts by editing the fstab file in /etc/fstab. Add a command to the end and restart the machine. Personally, I haven’t tried this because it’s a potential security risk and I didn’t need 100% uptime.
