help with some basic osx terminal commands. fixing permissions on NAS share
I'm hoping someone here can help me. I'm computer literate but by no means an expert! I'm simply trying to recover data from my DLink DNS343 NAS mounted on my X86 iMac using SMB. Somehow, in moving to a new computer, I have lost access to some files on the NAS. Just some files are access denied.

After 6 hours of research, I think what I am supposed to do is fix the permissions on the NAS. The option to change them via the finder is not there in this case. It simply says "No Access".

So i think what i need to do sounds something like the following:
Use terminal to get root access to the SMB NAS share.
Execute chown and make me the owner of all folders and files
Execute chmod and change all files and folders to 777

Then I can hopefully access all the files and get them the heck off the thing and use an external hard drive like every other average joe who doesnt know how to work a NAS.

If anyone can help, I would appreciate it SO MUCH. The NAS currently stores all my family videos, photos, etc etc.
SmilieThanks!

radwho

RADWHO(1)							 FreeRADIUS Daemon							 RADWHO(1)

NAME

       radwho - show online users

SYNOPSIS

       radwho [-c] [-d raddb_directory] [-f] [-i] [-n] [-N nas_ip_address] [-p] [-P nas_port] [-r] [-R] [-s] [-S] [-u user] [-U user] [-Z]

DESCRIPTION

       The  FreeRADIUS server can be configured to maintain an active session database in a file called radutmp. This utility shows the content of
       that session database.

OPTIONS

       -c     Shows caller ID (if available) instead of the full name.

       -d raddb_directory
	      The directory that contains the RADIUS configuration files. Defaults to /etc/raddb.

       -f     Behave as the 'fingerd' daemon - waits for one line of input, then prints the output with lines 
 terminated.

       -i     Shows the session ID instead of the full name.

       -n     Normally radwho looks up the username in the systems password file, and shows the full username as well. The -n flags prevents this.

       -N nas_ip_address
	      Show only those entries which match the given NAS IP address.

       -p     Adds an extra column for the port type - I for ISDN, A for Analog.

       -P nas_port
	      Show only those entries which match the given NAS port.

       -r     Outputs all data in raw format - no headers, no formatting, fields are comma-separated.

       -R     Output all data in RADIUS attribute format.  All fields are printed.

       -s     Show full name.

       -S     Hide shell users. Doesn't show the entries for users that do not have a SLIP or PPP session.

       -u user
	      Show only those entries which match the given username (case insensitive).

       -U user
	      Show only those entries which match the given username (case sensitive).

       -Z     When combined with -R, prints out the contents of an Accounting-Request packet which can be passed to radclient, in order  to  "zap"
	      that users session from radutmp.

       For example,

	      $ radwho -ZRN 10.0.0.1 | radclient -f - radius.example.net acct testing123

       will  result  in  all  an Accounting-Request packet being sent to the RADIUS server, which tells the server that the NAS rebooted.  i.e. It
       "zaps" all of the users on that NAS.

       To "zap" one user, specifiy NAS, username, and NAS port:

	      $ radwho -ZRN 10.0.0.1 -u user -P 10 | radclient -f - radius.example.net acct testing123

       Other combinations are also possible.
