I remember such tool I used it a couple of years ago it was easy to use.
I've been searching google but I just cant remember the name of it.
The name could have ended in d like in daemon...
Tool was commandline.
Sourcecode was either GNU or BSD or other free of the kind.
I had to download it from a webpage or I installed it from Freebsd ports can't remember now..
Usage was something like ###d mount /usr/sharetofriend where ### is the name of the tool
On the webpage that showed thus shared filed you could see those files permissions etc.
Any ideas?
