File Permissions Of PHP Session Files


I noticed that the file permissions (unix) of the PHP session files
have only read and write permissions for the Apache process (600 or rw-
--- ---).

Does anyone have any idea where this permission is set ? I can't find
any
umask or chmod settings for it in the php.ini file. Can't find
anything in
the httpd.conf either. Is it set in the PHP code that implements
session_start()?

.php Files - Permissions Are Set Public Readable - So Can Public Get To See Actual Raw File?
As a newbie to PHP is it in anyway possible for a casual web surfer to
actually get to see the PHP behind my .php file.

E.g.

if index.php contained PHP code to check if the page had been called with a
variable such as "password", is there anyway a public member can get to see
the raw php file and therefore see what the password is?

index.php might be:

if ($_REQUEST[password]="secret") {[color=blue]
>Then show one page[/color]
else[color=blue]
>show another page[/color]
}

So if a user visits with
index.php?password=secret

they get to see the secret page.
But as the index.php has to have file permission set so that anyone can read
it, I'm worried that the public can just somehow view the file and learn the
password.

Files, Permissions
I need to be able to set the owner properties of a file that is being uploaded so that it can be counted towards the file quota. Basically my setup is as follows: A user logins in, uploads a file, and this file is saved in a directory out of the public folder.

The problem is that the group and the owner IDs are being set to 'nobody'. This means that the files are not being counted towards a users file quota since it is setup (and I cannot change this part) to count quotas based on file owners. I tried using chgrp and chown but it says I dont have permission to. I cant figure out how to do this.

Permissions / Retrieving Uploaded Files
I have set up a website where visitors can upload files. We then ftp into the server to retrieve those files, however we cannot access them as they are chmod'ed to 600 by default.

How do we gain access to these files, or chmod them when they are first uploaded by the user so we can download them with ftp?

Added note - the server is telling me that the owner of the uploaded files are 'apache',
which I guess is the default set up.

Also tried the chmod command, but had no luck 'permission denied'..

Session Permissions Change Without Warning (HELP)
I run Apache2 and PHP5 and most of the time it works fine with my scripts.

Then occasionally, and it doesn't seem to make any difference when,

I've checked the /private/tmp folder (desig in php.ini) for permissions

a website, it places a session tmp file in /private/tmp just like it

File Permissions
Im in the process of creating a web based frontend for a program called ASK (Active Spam Killer - http://a-s-k.sourceforge.net) and am currently running into a problem. Currently there is a perl based web front end, but it lacks functionality, and is rather bland, although it does work, and it works without changing any file permissions.

The problem im running into is that PHP requires me to make changes to file permissions (ASK files are located OUTSIDE of the web tree) which might end up causing problems as far as security and privacy of email. Has anyone come to any reasonable answer for this type of problem as im sure its a issue for other programs people write.

File Permissions....
I've read the stuff concerning writing to a text file and the related file permission issues on this forum.I have a script that does just that, it takes user-entered data from a Web Form and dumps it to a text file on a server.

This works fine on my private server, but is giving me the error...."Could not open stream.Permission denied on Line..." on the company server...The Company machine uses Windows XP.

I've tried talking to the System Administrator regarding the Permissions,but he says that giving READ/WRITE/EXECUTE Permissions could create Security Issues.

I have been told that previously,a script written in ASP had been used that did exactly the same thing i.e writing to the text file, but there were no File Permissions needed to be set!

File Write Permissions
I'm trying to get an open source PHP app working for my company.  It's giving me the following custom error:

FreeMED was unable to create a file to record the healthy status of the system.
The FreeMED directory should be owned by the user that the webserver is running as...
Usually this is 'apache'. You can also fix this by giving universal write access to the home directory of FreeMED.

But that is not advisable from a security standpoint.
I've narrowed it down to the line of PHP that's breaking it here:

$test = CreateObject('FreeMED.FreeMEDSelfTest');
As far as I can tell, I've made the directory it's using as open as possible and it's still giving me that error.  The owner is apache (user and group) and the permissions are (temporarily) set at 0777 (universal read/write).

Is there some PHP or Apache configuration that needs changed to allow PHP this kind of permission?

Upload File Permissions Problem
I've moved an existing site (which I didn't write) from a apache/php/mysql
host under windows to a linux apache/php/mysql host.
I've sorted out most problems except one.

There is an upload function on the site, which uploads files via POST to
temp folder and then moves it into a folder on the host using php function
move_uploaded_file. Under windows this works fine but on the linux host the
uploaded file is created with 600 permissions so it cannot be accessed later
by site visitors. The folder it is uploaded into has 755 permissions. Is
there a way of setting the default file permissions so each uploaded file
can be set to say 644 or do I need to chmod each file after upload?

Set Up The Permissions So That My Script Can Simply Fopen A File For Writing.
I am rather new to PHP and a relative newbie to Linux too.
I have a webserver at home (Apache 2.0.48 on SuSe 9.0, PHP4).
I have some scripts, one of them needs to be able to create logfiles
somewhere on my machine. It must also later be able to read from and write
to these files again.

Sofar I get a permission error. I tried chmodding 666 or 777 the directory
in which the files could reside, to no avail.
How do I set up the permissions so that my script can simply fopen a file
for writing. Or if that's not the issue, what am I doing wrong or
overlooking ?

The errors:
Warning: fopen(logfileslog1.txt): failed to open stream: Permission denied
in script1.php on line 142
Warning: fwrite(): supplied argument is not a valid stream resource in
script1.php on line 154
Warning: fclose(): supplied argument is not a valid stream resource in
script1.php on line 161
It's the first I am puzzled about, the 2nd and 3rd are a logical
consequence.

By the way, reading from and writing to a file I have previously created
myself with exactly the names I tried to get created by the script (echoed
the name, ok) is no problem at all.
So I don't think it has much to do with a safemode or open_basedir setting.
I also tried creating the scripts in the same dir the script itself resides.
Did not work either.

do lots of other php stuff
$html -> send_footer() // found in main.inc.php and itself 'includes' footer.php

Has anyone any idea or am i being too vague here? Do I need to do something else at the beginning of footer.php that 'gets' the variable again from the session file? If so, how? The session ID is accessible to it cos I had it print it out to make sure, and the session file does definately hold a variable of the right name, I just can't return the data for some reason.
