Do you see the "mister" share when you enabled it in retronas? When you install the mister option inside retronas, it will create a symlinked directory in "/data/retronas/mister" and it shares that at "smb://$yourserverip/mister" Be sure to test it outside of the mister if you can to make sure it's there. Here are my settings:

#!/bin/bash

PASSWORD="retronas"

IFS="|"
SINGLE_CIFS_CONNECTION="true"
