They managed to get 700,000 comments into the system before we caught it, but the traffic and strain on the MySQL server and the webserver (PHP) while it was going on brought the server to its knees. I've put some iptables rules in to block the attacks and things are back to normal. The server (A vmware VM w/ 2 CPU and 2 GB of RAM) never crashed, but it certainly was on its knees. The distribution is Gentoo 10.1. My only other problem is PHP hanging on MySQL returning an emtpy set.(mysql_num_rows = 0).

[PHP] Re: Path question

Hello All,
Is there a smarter way to do includes by setting up a path or something
where I don't have to include /home/domain.com/includes/include_file.php
Apparently my path is as shown above, but I would prefer to just put in
/includes/include_file.php
Thanks!
Jack
Here's how I do it. For every application, I have a config file with all my
common assignments, including common paths, e.g.,
define('EDITPAGE_ROOT_DIR', $_SERVER['DOCUMENT_ROOT'] . '/editPageSR/');
define('EDITPAGE_IMAGES_DIR', EDITPAGE_ROOT_DIR . 'images/');
define('EDITPAGE_DATA_DIR', PAGE_ROOT_DIR . '/editPageFiles/');
So, in your case, I'd have
define('INCLUDE_FILE', $_SERVER['DOCUMENT_ROOT'] . /includes
/include_file.php);
So all I need is to use INCLUDE_FILE

Hi Ethan,
Are you using suPHP or suExec? I believe the server chokes on 777
permissions in those cases.
Have you checked the permissions in the command line (sorry for the basic
question, but just making sure I know what you've already done?)
Also, can we see some of the code you're using to handle the file
processing?
Thanks,

Adam -
Thanks.
1] Pardon my ignorance but I do not understand this - Are you using suPHP
or suExec?
suPHP and suExec are two modules that allow PHP to run with the permissions
of the user, making it easy to write files to disk. However, suPHP (and I
believe suExec, but I can't remember for sure) does not like 777
permissions.
2] I changed the permissions to 755 and the Permission Denied message
went away.
Check!
3] Have you checked the permissions in the command line? Yes
Check!
4] Here are some code snippets:
$fptr1 = fopen(chessboard, r+); //this works
$fptr2 = fopen('chessboard', 'w'); //this deletes the file, as it should
for($i = 0; $i 8; $i++)
{
for ($j = 0; $j 8; $j++)
fprinf($fptr2, %s , $results[$i][$j]);
fprinf($fptr2, \n);
} //this never writes, so I am left with an empty file
Can you try a simplified form that checks for success along the way? How
about something like the code below to see how far it gets (I haven't
tested, but it should be close):
?php
// let's make sure you see the E_WARNING errors if present for file
functions
error_reporting(-1);
// set var for later
$cost = 120.89;
if (!($fp = fopen(test.txt, 'w'))) {
echo Can't open or create file!;
} else if (!($len = fprintf($fp, In the year 3000, a Coke will cost %01.2f,
with tax., $cost))) {
echo Can't write to file!;
} else if (!(fclose($fp))) {
echo Can't properly close file!;
}

Very rusty with PHP.
We moved our web site to a new hosting service (godaddy). PHP changed
from 4x to 5.2.17.
I can no longer change $_SESSION variables after the first use.
First call to form - start session create variables
Second call - can read variables, change existing ones (but they do not
persist to next call) - cannot create new variable without an error
Using $_SESSION['varname'] always
session.auto_start off
register_globals off
session.use_only_cookies off
I assume this is setting difference but I can't seem to find it.
OK, here's is what is happening. I think my web hosting service is just
really slow. I am storing the cookies in a unique directory. I create
the directory when I start the session. It appears to take a long time
for the directory creation to occur. The code is posted below. You can
test it at this link: http://www.injection-moldings.com/upload%20test1.php
1. First time you call,
the session starts,
variables assigned to $_SESSION -
but no session ID ([PHPSESSID]) yet
2. Reload the page,
previous $_SESSION data lost
but markdir value appears in cookie which is the hash value for the
session path.
Still no session ID
3. Reload -
session ID appears [PHPSESSID]
session data starts saving $_SESSION['test'] will increment
Code:
?php
ob_start(); //start output buffering
// 10-2007 added java download text to first page
if(!isset($_COOKIE['makedir']) ) {
$unhashdir = startNewSession();
cfinitsession($_SESSION) ;
$_SESSION['mystep'] = 0;
$_SESSION['SUBMIT'] == 'auto';
$_POST = array();
setCookie('pagereload','0',0,'/');
$_COOKIE['pagereload'] = 0;
$_SESSION['pagereload']=0;
echo 'pstarting new session';
} else {
$unhashdir = '';
if (!setupSession1($_COOKIE['makedir'],$unhashdir)) {
die ('Could not start upload session');

Re: [PHP] Permission Denied - Help Requested
Thanks. What do you see if you run this? Can't open or create file! Ethan OK, If you're running PHP as an Apache module, by default it won't have permissions to write to the directory (this is by design to avoid security issues.) You can do something like the following: 1. Create a directory for writing files outside of your public directory (let's call it uploads.) 2. Change the group associated with the directory to Apache: sudo chgrp -R www-data /home/username/path/to/uploads 3. Change the permissions on the directory so the group has write permissions: sudo chmod -R 2775 /home/username/path/to/uploads 4. Then try the script again. See if that works.

Also with the -R option, and with apache as the owner, also with the chgrp. All these commands are run as root.. Help and advice please.

Did you set up the user Apache? On a standard install for Debian (using apt-get), apache is usually set up as the user/group www-data: http://wiki.debian.org/Apache http://wiki.debian.org/ApacheThe root user typically owns the /var/www directory. I usually set up virtual hosts within one of the other accounts and then change the group on a directory outside of the public directory specifically set aside for uploads and run the commands I sent. However, in the case of your example, I believe you can just run the 2 commands I sent on the /var/www/output_files directory and you should be able to write the files. sudo chgrp -R www-data /var/www/output_files sudo chmod -R 2775 /var/www/output_files Hope this helps, and sorry if I misunderstood something in your configuration or troubleshooting.
