Question: I am learning how to use Putty to access Linux servers and I am looking into setting directory permissions at the moment. For this, I did some simple test commands. I created a test directory and set the permissions to 0 like so

```
chmod 000 myTestDir

```

My understanding is that the first digit sets the permission for the owner of the directory, the second digit sets the permission for groups (which I am not sure what they are) and the third digit sets permissions for the rest of the world.

So now I tried to delete the folder in my ftp client, logged into the server using the same credentials as in Putty. I wasn't able to delete it which was the expected behavior since I set the permission to 0.

However, I was still able to delete the directory in Putty doing

```
rmdir myTestDir

```

Why am I able to delete the directory? I set the permission to non-readable, non-writable. Does using Putty command line automatically override those permissions?

After waiting about 10 minutes the background scanning ended to 100% and now Netbeans is usable again.
Just install the latest JRE for Apple found here : <http://support.apple.com/kb/DL1572?viewlocale=en_US&locale=en_US> and it should work just fine!
