[Resolved] Help with Unix Permissions

paulnaj

Does anyone understand how this could happen?

Here's what I did:

$path = getcwd(); 
mkdir ($path."/NewDirectory", 0666);

But, when I look at the directory in the browser ... get the permission denied note. Had a look in cuteFTP to see what the built-in CHMOD function says the permission is 0644 and not 0666, as I put in mkdir()!!

Tried 0777 and got 0755 !! There seems to be a pattern.

Also, to top that I can't access the folder in cute at all (can't change permissions, can't look inside).

So, just to find out what's happening, I used another script to (successfully) remove the folder:

$path = getcwd(); 
rmdir($path."/NewDirectory");

It seems that:
1) mkdir() creates a folder, but with 'lesser' permissions !!
2) Same folder can only be deleted with rmdir() !!

Anybody really understand permissions?

Cheers,
Paul.

Hi!

When u create the dir whit php like this the dirs owner is "nobody" and not the "ftp-owner", just "nobody" (your script) can delete it.

After "nobody" have created the dir, "nobody" can CHMOD it.

Hi gammaster!

Thanks for your reply.

Do you know how I can control who is the owner? Either in PHP ot FTP.

Thanks,
pnaj.

Sorry but i know not enough about it.
But the wise guys sayes that it`s a risk to handle with "owner changing" if u not are 100% sure about what u are doing.🙂

I use ftp instead when i have to create dirs.
Have a look at http://www.phpbuilder.com/manual/ref.ftp.php

If u use this in your online script u have to store login-info for the ftp online and that can be a security risk. But if u create the file myFtpIni.php, put it above u html_public (if thats the name) and include it, it`s quite secure.

$ftp_host = "thehost";
$ftp_user = "user";
$ftp_pass = "pass";

Sorry for my bad english.

Hey, gammaster,

Now that's a good idea ... it solves another problem I've been having as well ...

Mange takk meget mye (hope that's correct).

I`m glad you got an idea.
Your norwegian are outstanding.
