Default_Permissions in config.php

[nickgiguere]

Can anyone tell me how to set the default_permissions in the config.php file so that new folders created in the cache directory (or any directory really) are set to 755? I don't understand how to translate the "1520" or "436" to octal...

 'default_permissions' => 
  array (
    'dir_mode' => 1528,
    'file_mode' => 436,

Assuming you are using Windows, Click "start". "All Programs", "Calculator".

Turn on scientific mode.

Select "Oct".

Enter 755

Select "Dec"

The answer should appear on your screen.

Failing that, converting from Octal to Decimal (in 4 digits) is reasonably simple.

Split the number into columns. working from right to left.

The first digit is the same in octal as it is in decimal, so "7" is "7". Call this your "running answer".

The next digit is the "8"s column, so you multiply that digit by 8 and add it to the running answer.

The next digit is the "64"s column, so you multiply that digit by 64 and add it to your running answer.

The next digit is the "512"s column, so you multiply that digit by 512 and add it to your running answer..

The next digit is the "4096"s column, but since we're talking permissions, you probably won't need that one.

Thank you so much! I couldn't find anything online. I guess I didn't realize I needed to convert an octal number into decimal.

It appears that answers my question for 'file_mode'. How about 'dir_mode'? That's a 4 digit number. When I convert 755 to decimal I get "493".

Wait, nevermind. I remember reading somewhere here on the forums that 1and1 controls the security settings on all files (644 in this instance) no matter what you set in the config.php.

For directories there is a so called Group-ID.
For this the chmod command was extended to 4 digits, the first to define the behaviuor for directories.
See e.g. here http://uw714doc.sco.com/en/man/html.1/chmod.1.html for details.
So you set directories not to 755 but to 2755.
And oct(02755) = 1517

If you do not have any windows calculator at hand you could even write

 'default_permissions' =>  
  array ( 
    'dir_mode' => octdec('2755'), 
    'file_mode' => octdec('755'), 
  

to the config.php.
