Folder Locking

You can do it either my right clicking and going to properties but then it would depend on the access level of the other person your locking it from, or you can use other software, alternatively you can keep it on a usb drive.

If your looking for software to do it for you -

/ There may be paid software that does it better, but even if there was, I wouldn't be allowed to post it.

and Steve.... the forum rules, say that you should introduce yourself before making other posts :)

EDIT: I didnt realise the question was directed at a satbox, you can chmod the folder via ftp assuming the other users would access the box via different usernames.

I would assume there is a Linux program, but Linux isnt my strong point, try googling something like 'linux restrict access to folder'

Steve,

Not sure whether this will work for box but should do.......You have a couple of options either

Zip the file/folder with a password

You can password protect a zip file. Proceed as follows:
Create a directory for this experiment, and name it test.
Copy a few files and paste them into this directory so it isn’t empty.
Now open a terminal and enter:

zip -e -r /home/Desktop/newtest /home/Desktop/test

Enter password:
Verify password:

Now you have a file newtest.zip which is password protected. (you can/could delete test)

zip with -e option encrypts the contents of the zip archive using a password.

This encrypts with standard pkzip encryption which is considered weak.
However, the job of protecting the file is done, because even the root user needs
the password or should be a hacker to decrypt.

To unzip that same folder issue the command:

unzip <Directory_Name>.zip

You will then be prompted for the same password you gave for the encryption.
Once you successfully enter the password the file will be unzipped.

Or alternatively You can change the folder's permissions so no user other than root can
access the files inside:

Code:
chmod 600 /path/to/folder

Then set the owner as root (if not already).

Code:
chown root:root /path/to/folder

This will set your folder so that all user accounts on the local machine are
denied access to the folders contents, except for the root account.

Hope it helps, but i just see Ten in here so he may help further lol

That's all i knew off hand mate,
Give it a while someone may add/suggest something else!
A tool or add-on

Haven't really had a need for this as yet lol
But Yes would be via telnet
