[RESOLVED] File Permissions

adam_in_suffolk

Hi,

I hope that someone can put me out of my misery.

I have created a script that uses standard I/O functions to create a file.

	$fno=fopen('mypage.html',"w");
	fwrite($fno,$data);
	fclose($fno);

This works fine as I have the folder permissions set to 777.

However, when I try to edit the file from an ftp client, I get permission denied. I can rename it, and delete it from ftp, but not edit and save it. I added a chmod to my code and set the permissions of the generated page to 777 as a test, but alas the same result.

Does anyone have any ideas?

Just as a point to note; it seems that the created file is set to owner 'nobody', and not the domain owner account. I tried to use chown to change it to the domain owner account (which is the ftp account), but received a permission denied in the script. I do not know if this is something to do with it, as quite frankly, it is way above my head.

Thanks

Adam

1.) What does your CHMOD call look like? Are you using an octal?
2.) Try chmod-ing it to 7777 so that anyone in any group can read/write/execute it.

7777? Erm... is that... valid? In octal form, it should be 0777.

What FTP client are you using? Is there any way for you to check the file permissions from the FTP client? I know in CuteFTP Pro, you can go the properties of a file and it gives you a nice GUI (along with the numeric equivalent) to edit permissions.

well, octals start with a 0, so I guess it should be 07777.

Basically, it's this:

     |  Owner  |  Group  |  Public  |
      ==============================
     |   UID   |   GID   |  Sticky  |
      ------------------------------
     |    7    |    7    |     7    |
      ------------------------------
Read |    X    |    X    |     X    |
Write|    X    |    X    |     X    |
Exec |    X    |    X    |     X    |
      ------------------------------

so you set the UID, GID, and Sticky settings. It's just an option. I'm not saying it will work.

The permissions of the script created file are being successfully set to 777 with the following command:

chmod($myfile, 0777);

This still does not solve the problem. Furthermore, as the files it creates are html pages for the root, it will only work if I set the root permissions to 777, instead of being able to use the script again 755, which would be possibe if it was the domain owner that owned the files and not 'nobody' (I guess).

do what I do... run your own webserver... makes like 100% easier than hoping that someone else setup their hosting correctly 🙂

Here's one thing you can try. First, delete mypage.html from your server. Now on your home computer make a file called mypage.html and upload it to the server. With your ftp program chmod mypage.html to 0777. Don't use php chmod for that last step.

Thanks for the tips guys. I have managed to do it, albeit a bit of a fudge.

I create the page in a temp folder with permissions of 777, and then ftp it via php script to the root of itself..... mad or what!
