# To enable sftp:
# open a shell on your unraid server and issue the following commands
cd /etc/ssh
ssh-keygen

# Enter the name of the keyfile (sftp_rsa_key) and no passphrase.
# You will get two files sftp_rsa_key and sftp_rsa_key.pub. The public 
# key needs to be converted to another format to make it usable by 
# proftpd:
ssh-keygen -e -f sftp_rsa_key.pub | sudo tee sftp_user_keys

# You will get a new file sftp_user_keys. Now the owner and permissions will need to be changed:
chown nobody:users sftp_rsa_key sftp_rsa_key.pub sftp_user_keys
chmod 600 sftp_rsa_key sftp_rsa_key.pub sftp_user_keys 

# Now to make your system restore the correct permissions of this keys on boot you will need to modify the mountscript:
nano /boot/config/plugins/ProFTPd/mountscript.sh

# Insert the following lines:
chown nobody:users /etc/ssh/sftp_rsa_key /etc/ssh/sftp_rsa_key.pub /etc/ssh/sftp_user_keys
chmod 600 /etc/ssh/sftp_rsa_key /etc/ssh/sftp_rsa_key.pub /etc/ssh/sftp_user_keys

# Now edit your proftpd.conf file and insert:
<IfModule mod_sftp.c>
        SFTPEngine on
        Port 2222
        SFTPLog /var/log/sftp.log

        SFTPHostKey /etc/ssh/sftp_rsa_key
        SFTPAuthorizedUserKeys file:/etc/ssh/sftp_user_keys

        SFTPAuthMethods publickey

        SFTPKeyBlacklist none
        SFTPDHParamFile /usr/local/SlrG-Common/usr/local/etc/dhparams.pem
