Maps with a red sign

Could somebody explain to me what it means if a red round sign with a white cross (see attachment) is shown on a map?
Thanks.

Hi Hennie,

there is no attachment?.

I struggled a bit with it. Hopefully you see it now.

Does this work better?

Those files/folders are part of [ root ] [ / ]!!!!
Which means... one has to be [ Administrator ] !!!!

And if I am not mistaken, you can become almost 'root' via a terminal:

Code:

gksudo nautilus

but you may still not have access to such files for security/safety of the system (A bit like Windows 8 approach to the registry and Administrator privileges!)

I am the owner so could you tell me how I make myself an administrator in order to get the most extensive rights? Thank you.

The normal way is to open a Terminal (Menu | Accessories | Terminal) and enter:

Code:

gksudo nautilus

If you intend to change things via a terminal, open a new terminal window - not the one where you entered 'gksudo nautilus' or the window that opens with it.

If you want absolute root privileges:

BUT BE WARNED! You could damage your running system if you are not careful!

In windows, you have "Administrator", "System", and normal users. In linux you have root, and not root.

You root is more like the windows user "System", there are absolutely NO restrictions for the root user, they can modify anything, anywhere, anytime, for no reason.

You can pretend to be root by running

Code:

sudo command_to_run_as_root

or for gui programs

Code:

gksudo command _to_run_as_root

To run something truely as root, the you need to run

Code:

sudo su root

put in your password and your prompt will change to reflect it, root@dir# then you will be able to run basically anything as root.

To login on the computer as root, you will need to set the root password,

Code:

sudo passwd root

It will ask for your password and then it will ask for the new password 2 times. then login with the username root and the password that you set it to.

There are usually caveats though if you do decide to create a root account - your system could become vulnerable whilst online and you have the potential to make your system unstable!
