folders, permissions and command lines?

[fredbook86]

hey guys!

I'm totally new to all that stuff.
I never worked with a NAS, command lines and setting permissions :/

unfortunately, a friend of mine set up my freeNAS and did all the configuration.

i hope it is ok, to post my question here and that i start directly!

on my NAS i've got 4 folders: (btw i've freeNAS 8.2.0 release)
name1
name2
name3
public

and i have the according users:
name1
name2
name3
public

user name1 should have access to all 4 folders
user name2 only to folder name2 and public
user name3 only to folder name3 and public
user public only to folder public

then i searched through this forum and found command lines like:
chown, chgrp, chmod 770, chmod 700

my question is now: how can i use these commands to config my permissions as mentioned above?

To be honest, you should read the manual AND consult your friend that helped you setup the server. If you don't know what those commands do the last thing you want to do is somehow prevent anyone from logging into the server because you ran a command that did something you didn't intend. I'm fairly new to FreeBSD/FreeNAS, but the last thing you want is to start a thread titled "I think I broke my server" and people start telling you what to do and you are like "uhh... can you explain that in English?"
