I have WebDAV installed on my MyBookWORLD and I can use it to access the HDD from outside of my local network. I wanted to use Twonky for this but there appears to be no way as it drops the DynDNS address for the local IP everytime. Anyway, I have family members and friends I would like to give access to, however I don't want them to be able to access EVERYTHING. I have personal stuff on there, but sharing pictures and videos would be nice.
So basically, is there a way I can setup multiple users (I know I can have many users in general) with different levels of access (i.e. limited to certain folders and files)?
Please note, I have limited Unix skills so I am hoping someone can give me some detailed, even step-by-step guidance.
