PHP - Exec() Function - Permission Denied !?
Hmm, hello everyone, i'm running my php in an ubuntu server and I'm trying to run a command using exec (i.e. 'echo 1 > /var/www/test.txt') but I always get a permission denied issue, although i've already changed the permissions to 777 (read-write-execute) Any solution? Similar TutorialsI'm trying to open a URL using fopen() and I keep getting this error: Code: [Select] Failed to open stream: Permission deniedI can not work out what is wrong, it's not a firewall as far as I can tell. Hi. I'm trying to make my folder management tool able to remove stuff. Problem is, I get permission denied.
I've checked the NFTS perms for the share and for the folder. It's also not read only. I logged into my other workstation as the service account the web server is using and opened a DOS window and did "rd \\server\share\folder" and it removed it no problem. It just fails in PHP. Any idea what I should be looking at? Thanks!
Edited by Strahan, 02 August 2014 - 05:06 PM. I want to delete an image file from a folder using unlink. The code is : Code: [Select] $movie_id = $checkbox[$i]; $sql = "DELETE from movie_basic_details where `movie_id` = '$movie_id'"; $result = mysql_query($sql) or die(mysql_error()); $sql1 = "DELETE from movie_details where `movie_id` = '$movie_id'"; $result = mysql_query($sql1) or die(mysql_error()); $sql2 = "DELETE from movie_stars where `movie_id` = '$movie_id'"; $result = mysql_query($sql2) or die(mysql_error()); $query = "select movie_name from movie_basic_details where movie_id = '$movie_id'"; $res = mysql_query($query) or die(mysql_error()); $data = mysql_fetch_array($res); unlink("upload/movies/".$data['movie_name']); } The entries in the database have been deleted but only the image corresponds to that entry do not get deleted. The following warning comes up : Warning: unlink(upload/movies/) [function.unlink]: Permission denied in C:\wamp\www\ContentPanel\deletemovies.php on line 23 I have uploaded the files using $_FILES server variable and move_uploaded_file function. I am running this script on windows 7. Please Help. I am getting this error Warning: ftp_put() [function.ftp-put]: Can't open that file: Permission denied in /home/chris/public_html/site-name/wp-content/setup.php on line 62 Code: [Select] $conn_id = ftp_connect($host, 21) or die ("Cannot connect to host"); ftp_login($conn_id, $usr, $pwd) or die("Cannot login"); // turn on passive mode transfers (some servers need this) // ftp_pasv ($conn_id, true); $upload = ftp_put($conn_id, $file[0], $file[1], FTP_ASCII); print (!$upload) ? die('Cannot upload') : 'Upload complete'; print "\n"; The permissions to the file is 0644, if I change it to 0777 ftp_put complains and says the file is not found. How can I ftp this file? What is going on? Thanks, Chris Hi I have an image uploading script that won't upload images... It worked at one point when i had folder permission at 0777 but i was told that is risky so i changed it to 0775 Now it won't work and i can't use 0777. Any one know what i need to do to get it to work? This is my script: Code: [Select] <?php $salt = 35322232414; $name = $salt.$safe; $name = md5($name); if(isset($_POST['submit'])){ if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/png") || ($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/pjpeg")) && ($_FILES["file"]["size"] < 1000000)) { if ($_FILES["file"]["error"] > 0) { echo $_FILES["file"]["error"]; } else { $filename = md5(serverdate()) . $_FILES["file"]["name"]; if (file_exists("userimages/".$name."/".$filename)) { echo "Image already uploaded!"; } else { if (is_dir("userimages/".$name) == FALSE){ mkdir("userimages/".$name, 0775); //permissions } move_uploaded_file($_FILES["file"]["tmp_name"], "userimages/".$name."/" . $filename); echo "Image has been uploaded!"; } Error i get: Quote Warning: move_uploaded_file(images/73640de25b7d656733ce2f808a330f18/7fc9cb9cf5ae1f7a5dd9105d3f9559fb_63.jpg) [function.move-uploaded-file]: failed to open stream: Permission denied in uploadfile.php on line 41 Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/tmp/phpjrX3SO' to 'images/73640de25b7d656733ce2f808a330f18/7fc9cb9cf5ae1f7a5dd9105d3f9559fb_63.jpg' in uploadfile.php on line 4 Hi, On login page load, (even before submitting user name and pass) Debugger finds "permission denied error", can see it he goldpharm.co.il/authentication.php Now, when a user submit's user name and pass, nothing happens, it stays on the login page. I am not sure in what code the bug is , can you tell by the bug error in this page: goldpharm.co.il/authentication.php ? and how can it be fixed? , should I post the code? Thanks. I'm getting this error when I try to fwrite to a directory: Quote failed to open stream: Permission denied I have added the user www-data to the group which has permission to the directory? The directory is this: /home/directory1/documents directory1 = drwxr-x--- documents = drwxrwx--- Does anyone know whats going on? I have a PHP web system that store in a windows server. In the system, there is a function for user to upload files to another server (Shared server in Unix). When i try to upload a file, it gives warning: Warning: move_uploaded_file(\\unixserver/sharedfolder/upload/test.txt) [function.move-uploaded-file]: failed to open stream: Permission denied in C:\wamp\www\upload\index.php on line 40 For your information, my username has been assigned in xxx's group that has access to read and write on that folder. Besides, i'm able to open,create and delete files on that folder's server manually (samba). The safe mode setting is off. Does anybody has any idea why this thing happen? I am using apache web server on linux. I am using PHP for web designing. On web server, i want to show the configuration data by reading the ini file. I am creating this ini file from one php code itself. If this php code i run through linux terminal, the file is created with file and group owner as root.(i am having sudo rights on machine) Then if i try to read the ini file from my apache web server, it gives warning as failed to open stream: permission denied. I have tried changing the owner, and permissions to 777 of the file. Still it is not readable.
On the other hand, if i run the php code of ini file creation through web server, ini file is created with file and group owner as apche. and web server is able to read/ write the file.
But i want to create that file from root or some other user and later read/written by apache.
How to give this access permission?
Hi I'm trying to resize pictures for thumbnails I can do this correctly at linux command line with the following command convert ideologies.jpeg -resize 300x200 ./Thumbnails/testphp.jpg However trying to wrap this in PHP doesn't seem to work
// Upload file to server
if(move_uploaded_file($_FILES["file"]["tmp_name"], $targetFilePath)){
// Insert image file name into database
$insert = $conn->query("INSERT into Threads (Title, ThreadBody, filename) VALUES ('$Title', '$BodyText', '$fileName')");
if($insert){
$statusMsg = "The file ".$fileName. " has been uploaded successfully.";
exec("convert {['fileName']} -resize 300x200 wankertestphp.jpg");
}
If you look above I do successfully hit the "The File has been uploaded successfully" line so it is entering that If statement. I've also checked the Threads table with a Select * from Threads and I can see the $fileName variable is entering there. I've tried numerous different ways around the $fileName variable (removing the brackets...removing the brackets and the apostrophes")
Any help is appreciated. hi guys. i'm new to php and Apache and i have a problem. i'm trying to execute an exe file that i have in my folder, and the code i use is Code: [Select] echo exec('test.exe');i have tried using this with and without the ".exe." and still no luck. i have also tried using a different path Code: [Select] echo exec('C:\Windows\System32\mspaint');now these codes work when i run them from my php editor(PhpED), bun when i try running it on Apache it gets stuck. (just shows the web page as loading with no end. please help me out. i'm guessing it something with security. also if there is any other code i can use please let me know (i have also tried using system) I have a username alam for the server I have sudo access to execute linux commands. I could configure almost all files the root can do. I wrote this script on the server for test as I need to provide the server some functionality ----------------- Code: [Select] <?php $cmd="ls -l"; echo exec($cmd,$ret_value) .

Hi, I'm trying to build a 'simple' page to improve a process where I work.
I'm wanting to do this.
Read either the last line, the last 10 lines, or something I decide on from a log and display the output in table rows and columns.
I've done this before with loops and db query's, but don't know how to approach it using php only as this is the first time I'm using it.
So right now I have this in a table but it will only display one row.
<tr><td colspan="5"> how do i enable exec() in php.ini? where is php.ini? cant find it in the directories in my site. I have a PHP script containing the function exec which works fine in PHP 4 in IIS 7 on Windows 7. However this function does not work in PHP 4 in IIS 5 on windows server 2003. But I have to make it work there because that is what we have on our web server. Can someone provide a solution? Hey guys I usually code in C and I started looking into PHP which I think is pretty good. I'm wondering if there's a function that can be used to execute a command from a remote server on my local machine??? As example if I'd like to have a PHP page/script running on my server which when logged onto would display me a page with buttons like "PING, NETSTAT, IPCONFIG, TRACERT" and when clicked on it would exec those commands but not on the server but from my machine??? So that I would get the PING from my local machine to google.com instead of from the server to google.com ??? making any sense ??? thanks Please help me to solve this error Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'SYSTEM'@'localhost' (using password: NO) in C:\wamp\www\shop-script-free\includes\database\mysql.php on line 13 Warning: mysql_get_server_info() expects parameter 1 to be resource, boolean given in C:\wamp\www\shop-script-free\includes\database\mysql.php on line 14 Access denied for user 'SYSTEM'@'localhost' (using password: NO) Thanks you very much i have a bash script that i was running with cron jobs: #! /bin/bash start=1000 homedir="/home/alin/NetBeansProjects/Fragger2" numberofprocess=`expr $start + $2` i=$start currentnumber=`ps ax | grep index | grep -c php` case "$1" in start) while [ $i -lt $numberofprocess ] do if [ `ps axo cmd | grep index | grep php | grep -c $i` -lt 1 ] ; then /server/php/bin/php $homedir/index.php $i & fi; i=`expr $i + 1` done ;; stop) while [ $currentnumber -ne 0 ] do kill -9 `ps ax | grep php | grep index | awk {'print $1'} | head -n 1`; currentnumber=`ps ax | grep index | grep -c php` done ;; *) echo "Usage : " $0 "start|stop" ;; esac exit 0 and it was working fine, now i'm tring to make it run from a page . if(isset ($_POST['stop'])){ $conn->update("update `links` set `proccess`=0 "); exec("/home/alin/NetBeansProjects/Fragger2/Trans stop 0"); } if(isset ($_POST['start'])){ if(!preg_match("/^[0-9]+$/", $_POST['proccess'])) echo "proccess should be only a number!"; exec("/home/alin/NetBeansProjects/Fragger2/Trans start ".$_POST['proccess']); } and i don't know why it is not working, i have set for this folder all the permision for this folder "chmod -R 777 /home/alin" it doesn't stop running and i can't figure out why i have to kill the procces from the comand line to stop I'm trying to open a batch file in php with these contents: Code: [Select] @echo off java -classpath rscd.jar;lib/mina.jar;lib/xpp3.jar;lib/slf4j.jar;lib/xstream.jar;lib/hex-string.jar; org.rscdaemon.server.Server pause My PHP code is simply Code: [Select] $run = "C:\\Users\\Zorian\\Desktop\\EasyRSC\\Server\\run-win.bat"; echo exec("cmd.exe /c " . $run); It should open up a java applet, instead it just echos: Code: [Select] Press any key to continue . . . Hello, I was just seeing if someone could push me in the right direction. I have a form that uploads items to a database and it also includes uploading images to a directory as a part of that. That all works, but I was thinking for security it'd be best not to leave that directory as 0777 for permissions. In researching this I found the exec() function. I'm still figuring out the relation of who the permissions are associated with and why. All I know is if the directory has 0777 for permissions my script works just fine. I was just seeing if using exec to change the permissions during the process of uploading the images and then change back would be cumbersome and leave open other problems (there won't be any user-based input being passed to that) or if that actually would be the way to go for this. Thanks! -Frank |
