I am new user of Ubuntu. I have installed Ubuntu version 12.10 in virtual box.

The problem.

I downloaded a file called pcre in to /home/downloads.

I created a folder in pcre in home folder and moved the pcre file from download folder to pcre folder

I then copied the folder /home/dinesh/pcre to /usr/local/src/snort/snorttmp using the command

cp -a /home/dinesh/pcre  /usr/local/src/snort/snorttmp

When I am trying to access snorttmp folder, a message is displayed

" The folder contents could not be displayed. You do not have the permissions necessary to view the contents of "snorttmp".

Before copying pcre file into the snorttmp, I had access to snorttmp and was able to view the files present in snorttmp folder.

I then tried to see my files through the terminal

root@dinesh-VirtualBox: /usr/local/src/snort/snorttmp# ls -l

-rw-r--r--  1   root    root    5189146 Jan 24 00:18  2787                    
-rw-r--r--  1   root    root    19659   Jan 28 16:29  index.html           
drwxrwxr-x  2   dinesh  dinesh     4096 Jan 28 20:18  pcre          
drwxr-xr-x  10  root    root       4096 Jan 1  00:08  snort-          
drwxrwxr-x  6   dinesh  dinesh     4096 Jan 28 20:20  SnortRules        
drwxr-xr-x  2   root    root       4096 Jan 28 16:18  snorttmp

I find few of the files are marked in blue while the other files are displayed in white.

The files that were displayed in blue when I did ls -l are


2787 and index.html are displayed in white.

Kindly let me know what should be done to get permission to view my files.

It sounds like you are trying to get at that folder through the GUI. Check the permissions of the snorttmp and snort directories:

sudo ls -al /usr/local/src/snort/ | grep snorttmp

sudo ls -al /usr/local/src/ | grep snort

If those look ok (drwxr-xr-x root root), then there must be something more elusive going on. In that case, you can always try running Nautilus (file explorer) with elevated permissions (you also might first have to install gksu sudo apt-get install gksu):

gksudo nautilus

I did sudo ls -al /usr/local/src/snort/ | grep snorttmp Result drwx------ 14 root root 4096 Jan 28 20:43 snorttmp I also did sudo ls -al /usr/local/src/ | grep snort Result drwxr-xr-x 3 root root 4096 Jan 28 17:17 snort I installed gksu using sudo apt-get install gksu After this I was able to get into the snorttmp folder. I was able to see only two files in the snorttmp folder - 2787 and index.html file. The other files such as pcre, SnortRules, snort-9.6.0 were not visible. – Dinesh Jan 29 '14 at 4:39
I am able to see the other files now thanks BryceAtNetworks23 – Dinesh Jan 29 '14 at 6:04

@Dinesh You can +1 an answer once you have 15 reputation. So let's hope someone else +1's your question... – Aaron Feb 6 '14 at 14:58

Add sudo in front of the command, you want to run as super user. It should look like

sudo cp -a /home/dinesh/pcre /usr/local/src/snort/snorttmp

Then enter your password and press Enter
