Unfortunately the implicit conversion doesn't take into account the octal string so you end up with an integer version 644, which is 1204 octal The resutls are base-10 numbers that only LOOK like they are octal numbers. The function also ignores setuid, setgid and sticky bits, and will produce incorrect numbers if such a file is encountered. Instead, this brute-force code works. Maybe there is something more slick, but this isn't too CPU-intensive (note that it assumes you've error-checked that you indeed have a 10-character string!):Conversely, the UNIX-running servers allow that.The executable flag cannot be set as Windows determines it based on file extension. The write flag cannot be set as Windows determines write access based on ACLs, which are not integrated here. Note that this function has one argument for directory permissions and one for file permissions.This function also skips links.This is essential for me, since my script is also copying a bunch of files. Here's how Windows calculates the bitmask. Windows isn't integrating its ACLs at all. Here's the source of all this: (but it doesn't provide many details) If the file name is omitted, the permissions that the function will return are based on 000-permissions. Otherwise it will return a string converted to base-10 for chmod. So, IMHO, rabin's version is correct (it definitely worked for me). Always do checking on your values before handing it off to eval(). There are security concerns doing this as this modification allows any user to change ownership of their files to anyone else. To get around this problem you can use sudo, but be careful with what permissions you give. The only valid input of userid is a four digit numeric id, between 1100 and 1999. Hope this helps. The code that I think is relevant here I have included: Does the file need to be world writable, or will it suffice if only e.g., Apache can write to it. Do you have a set of applications that need to be able to write these files.
What if you made them run as the same group and set 0764 mode instead? Canceling the exetuging bit solves my night-sweat wwwwiiiuieuuewuwuuuwww:) Good point about that group thing. I will check that out and make a final descition. Am I wrong? According to your answer, I will use your solution. In addition, I don't think the method factors in at all here. In theory a GET request to a script could trigger something like this, if that was the design. This is a process setting that applies a default modification to standard modes. Files created with that mode will be totally unprotected from changes. Please be sure to answer the question. Provide details and share your research.

Number 1 means that youYou can also read moreHowever PHP converts: 0755 to it's octal value (493) and if you force to stay int, the value becomes: 755.I was once adwised to set the 'sticky bit', i.e. use 1777 as chmod-value. Rule of thumb: always prefix octal mode values with a zero. Do NOT do this if you don't have root privileges. When 'sticky bit' is set ONLY the fileuser can delete it afterwards, typically 'httpd' or something like that in case of an upload-script for example. Use simply '0777' or similiar.
You do not really have any other levels but read-only.The only thing is that the usergroups doesn't work.You can use a command to chmod the file for you, which is especially useful when you're making a script where you're setting it up so that your users don't have to peform a bunch of actions to setup the script. When i wrote my news program script, I only had two files. install.php and config.php. All you had to do was chmod install.php to 666 and open it up in a web browser and answer a few questions. The script itself setup the rest of the files and chmodded them for you. Parameters filename Path to the file.One component can be computed by adding up the needed permissions for that target user base. Number 1 means that you grant execute rights, number 2 means that you make the file writeable, number 4 means that you make the file readable. Add up these numbers to specify needed rights. Notes Note: The current user is the user under which PHP runs. It is probably not the same user you use for normal shell or FTP access. The mode can be changed only by user who owns the file on most systems. Note: This function will not work on remote files as the file toNote: When safe mode is enabled, PHP checks whether the files or directories you are about to operate on have the same UID (owner) as the script that is being executed. In addition, you cannot set the SUID, SGID and sticky bits. I was once adwised to set the 'sticky bit', i.e. use 1777 as chmod-value. The resutls are base-10 numbers that only LOOK like they are octal numbers. I am using it for an instalation script that has to CHMOD a bunch of files. This is essential for me, since my script is also copying a bunch of files. Note that this function has one argument for directory permissions and one for file permissions. In this way you can apply the 'x' permission on directories, and skip it on directories. This function also skips links.
I guess for very deeply nested directories the recursion with php can become problematic, but I can be wrong because I never investigated this. Conversely, the UNIX-running servers allow that. Solutions: 1. If your web hosting provider has a web-based control panel that lets you set file permissions, then you need to login there and make changes. 2. It is possible to contact the hosting provider and ask them about this issue; maybe they can make the changes. 3. It is possible to change the hosting provider that has servers run on UNIX, and keep the site there.An easy way around that is to use the octdec() function. Not as efficient, but works. You can use a command to chmod the file for you, which is especially useful when you're making a script where you're setting it up so that your users don't have to peform a bunch of actions to setup the script. So being in your local server, if you have a only read file and you try to erase, it will show that you dont have permissions even when you have already executed your chmod instrucction correctly. Just up the script it must work well in your internet server if it is a linux machine sobre chmod, Probablemente usas un servidor local para probar tus scripts antes de subirlos al servidor en internet.

You need a value that can easily computed and remembered if printed in octal. 511 (decimal) is the same as 777 (octal). You do not really have any other levels but read-only. Otherwise it will attempt to write to a new file. Do NOT do this if you don't have root privileges. Use simply '0777' or similiar. You may want to issue a touch() after writing and closing the file which update its modification time. This may become critical in a caching situation, if you intend to keep your hair.
It looks like the second one is needed so the server won't interpret the path as relative to blossom's home on townsville. Works with SSL-secured hosts.On UNIX, you may happily read the directory format for the native filesystem. Got to know that it uses windows-1250. Used iconv to convert it to UTF-8 and it resolved the issue. If you are unable or unwilling to install the serial device library for PHP, its still possible to communicate through a serial port or USB device.Lots of records show up a just one big using only the following:I noticed when using too many scripts at the same time to download the data from the site I was harvesting from, fopen and fread would go into deadlock. When using cURL i can open 50 windows, running 10 URL's from each window, and getting the best performance possible. Just a Tip:) If PHP is configured as an apache module it will act as whatever user the apache is. If apache SuEXEC's to otheruser:othergroup (e.g. root:root), that's what PHP will write files as, because it acts as a part of apache code. I suggest you double-check your SuEXEC configuration and settings. Note: you can't su to another user within the PHP code -- it has to be an apache directive, either through, or through.htaccess. Also note: I'm not sure how it all works (if it works at all) on Win32 platforms.This just bit me. I was not checking the filename part of a concatenated string.I tried append mode and it errors out so does not seem to be dangerous.The problem was that fopen() was failing when trying to access a file as a URL through apache -- even though it worked fine when run from the shell and even though the file was readily readable from any browser.For example if there?s a chat history containing only the last 25 chat lines. Now adding a line also means deleting the very first one. So while that whole writing is happening, another user might also add a line, reading the file, which, at this point, is incomplete, because it?s just being rewritten.
The second user would then rewrite an incomplete file and add its line to it, meaning: you just got yourself some data loss. If flock() was working at all, that might be the key to not let those interferences happen - but flock() mostly won?t work as expected (at least that?s my experience on any linux webserver I?ve tried), and writing own file-locking-functions comes with a lot of possible issues that would finally result in corrupted files. Even though it?s very unlikely, it?s not impossible and has happened to me already. So I came up with another solution for the file-interference-problem: 1. A file that?s to be accessed will first be copied to a temp-file directory and its last filemtime() is being stored in a PHP-variable.Anyway there won?t be any writing-interference between two PHP processes, assuming there can be no absolute simultaneousness between two (or more) processes. On win32 it appears that you can't re-open the input stream for reading, but rather you have to open it once, and read from there on. Also, i don't know if this is a bug or what but it appears that fgets() reads until the new line anyway. The number of characters returned is ok, but it will not halt reading and return to the script. I don't know of a work around for this right now, but i'll keep working on it.If you want to identify to the sites that you are using PHP. Regards, Richard Quadling.

It is required for X - Cart 5 operation ( current version is 5.1. 73 - cll ) Please make sure that the following file permissions are assigned ( UNIX only ): Please make sure that the following file permissions are assigned ( UNIX only ). This is important because WordPress may need access to write to files in your wp-content directory to enable certain functions. The diagram shows how. It cannot cover all cases. This guide applies to servers running a standard setup (note, for shared hosting using “suexec” methods, see below). On shared hosts, files should never be owned by the webserver process itself (sometimes this is www, or apache, or nobody user). For example, you may have a user account that lets you FTP files back and forth to your server, but your server itself may run using a separate user, in a separate usergroup, such as dhapache or nobody. If WordPress is running as the FTP account, that account needs to have write access, i.e., be the owner of the files, or belong to a group that has write access.
In the latter case, that would mean permissions are set more permissively than default (for example, 775 rather than 755 for folders, and 664 instead of 644). Unless you are experiencing problems with permission errors, or you want to, you probably should not mess with this. Some files and directories should be “hardened” with stricter permissions, specifically, the wp-config.php file. This file is initially created with 644 permissions, and it’s a hazard to leave it like that. See Security and Hardening. Try using it before modifying file permissions, it should work. (This may be true if different users uploaded the WordPress package and the Plugin or Theme. This wouldn’t be a problem for Plugin and Themes installed via the admin. When uploading files with different ftp users group writable is needed. In some cases, this may require assigning 755 permissions. Permissions will vary. This is a popular approach used by many web hosts. For these systems, the php process runs as the owner of the php files themselves, allowing for a simpler configuration and a more secure environment for the specific case of shared hosting. Group ownership is irrelevant, unless there’s specific group requirements for the web-server process permissions checking. This is not usually the case. All directories should be 755 or 750. All files should be 644 or 640. Exception: wp-config.php should be 440 or 400 to prevent other users on the server from reading it. No directories should ever be given 777, even upload directories. Since the php process is running as the owner of the files, it gets the owners permissions and can write to even a 755 directory. PHP-FPM, an alternative FastCGI server with shared OPCode, for use with Apache and Nginx. This function is often called chmod or set permissions in the program menu. It looks a bit confusing, but for now just note the sequence of letters. Then click OK.
But, at some point, you may need to see your hidden files so that you can change the permissions on that file. For example, you may need to make your.htaccess file, the file that controls permalinks, writeable. The screen display of files will refresh and any previously hidden file should come into view. Before you start using chmod it would be recommended to read some tutorials to make sure you understand what you can achieve with it. Setting incorrect permissions can take your site offline, so please take your time. Try each of these commands first and if they don’t work then go recursive, which will make even your themes image files writable. Replace DIR with the folder you want to write in If after that you still cant write, you may now try 777. The -R flag means to apply the change to every file and directory inside of wp-content. 766 is the mode we are changing the directory to, it means that the directory is readable and writable by WordPress and any and all other users on your system. Finally, we have the name of the directory we are going to modify, wp-content. If 766 doesn’t work, you can try 777, which makes all files and folders readable, writable, and executable by all users, groups, and processes. Start with low permissive settings like 744, working your way up until it works. Only use 777 if necessary, and hopefully only for a temporary amount of time. The username you use to FTP or SSH into your server is most likely not the username used by the server application itself to serve pages. By setting your personal files and folders owned by your user account to be World-Writable, you are literally making them World Writable. Now the www-data, dhapache and nobody users that run your server, serving pages, executing php interpreters, etc.So you should think carefully about modifying permissions on your machine. I’ve never come across anything that needed more than 767, so when you see 777 ask why it’s necessary.
Contact the Plugin author or your server support and request a workaround. So if you set the permissions too low, then your server won’t be able to access the file and will cause an error. Therein lies the method to find the most secure settings. Start too restrictive and increase the permissions until it works. To prevent the interpreter and php.ini file from being accessed directly in a web browser they are protected with a.htaccess file. The default permissions for this file are 755. This is interesting because it really works. You can try reading the file, writing to the file, etc.And as the owner of the file you can always change the permission modes back again. This is of particular use to limit the actions that web pages can perform on other parts of the operating system. Actions that are denied by the security policy are often hard to distinguish from regular file permission errors. Enforcing. Wizard.

This will include setting file permissions (see below), entering your license key, and setting up your primary administrator account. If you use DSO as your PHP handler, you must use 644 permissions. Make sure that no other system or user accounts can read your configuration file or modify any WHMCS-related files. To do this:For more information, see Configuring WHMCS in cPanel Site Software. After it finishes, you will see a success message, a link to the login page, and automatically-generated default login credentials.

We read all the feedback we receive and use it to improve our documentation. For Apache: There are three main scenarios: The blog post we wrote regarding MacOS Yosemite, Apache, and PHP outlines how to configure Apache to run as your personal user account. This approach is not considered secure enough to use on a dedicated web host, so the second or third option should be used. What this script basically does, is: This file is commonly used for multisite setup, but being called in every Grav call, you can also use it for other uses.

Permissions can allow our server computer to write and edit your files. Along with that, some files need to be protected from writing and editing, as a security measure. You can change your file permissions in many ways.
To change the permissions for a file or folder in cPanel, please do the following: Click File Manager. Select the Permissions link at the top of the page.Select Change Permissions. Make changes on the permission and hit Save. Click Change Permissions. First is the Owner; the owner is you, the person who has access to the cPanel or shell. Second is the Group; the group is other people on your server. Third is the World; the world is any visitor from the public (think world wide web). Read means the user is allowed to view the file. Write means the user is allowed to edit the file. Execute means the user is allowed to run the file. However, there are some files that you may not want anyone to see. If you remove the check for Read under Group and World, then the file will not show in anyone's browser (instead, visitors will see a 403 Forbidden error). We are only concerned with 3 digits, so if you see 4 digits, then ignore the first one. Thus 0755 is the same as 755. Also, the first of the three digits represents the permissions for the Owner. The second digit represents the Group. The third digit represents the World. You won't see any difference.) You will not need to use 777 on PHP files or folders. This allows hackers from the world wide web to edit your files. Thus, the last two digits of file permissions should never be 2, 3, 6, or 7. Traditionally, PHP is treated as 'nobody' on the server. Therefore, PHP is treated the same as any unknown visitor and must obey the permissions granted to World. HostGator have done so by implementing a special PHP security environment known as suPHP (or phpSuExec). You have already seen the two-dimensional matrix and the 3 or 4 digit numbers. Next, you see three letters which represent the Owner's permissions. Finally, the last three characters represent the World's permissions. In place of the 'w' will be a hyphen, meaning that write is definitely not allowed: r-x.
We can transfer website files, databases, scripts, and one free domain registration transfer. What qualifies me for a free transfer. HostGator provides free transfers for new accounts within 30 days of sign-up, and to newly upgraded accounts. For upgraded accounts it must be an inter-server upgrade to qualify. Please note that downgraded accounts do not qualify for free transfers. Depending on which type of account you sign up for, we offer differing numbers of free transfers. Please refer to the chart below to see what we include for new packages. Full cPanel Transfers is the number of cPanel to cPanel transfers that are included. Max. Manual Transfers is the maximum number of Manual Transfers that are included with your account. Total Free Transfers is the total number websites that we will move for you. Account Type Total Free Transfers Full cPanel Transfers Max. Manual Transfers online form to initiate your website content transfers. VPS accounts that have a control panel (either cPanel or Plesk) qualify for unlimited cPanel to cPanel transfers, or up to 10 Manual Transfers per VPS level. I.E. a Level 5 VPS qualifies for 50 manual transfers, while a Level 7 qualifies for 70 manual transfers. (Snappy 500 or VPS without a control panel) VPS accounts with no control panel are for advanced Linux customers who are comfortable with installing and configuring their own services. If you are not comfortable with installing and configuring their own services, we suggest upgrading to a Level 3 plan with cPanel. We will not be able to install and configure each service for you. We provide 75 free website transfers. The content transfers are free within the first 30 days; for any requests outside the first 30 days, we will reply back with a quoted price. We provide 100 website transfers. This will also include your emails and email accounts. Please note that this does require that your old host's cPanel backup generator to be active.
A few examples: An Aluminium Reseller account includes up to 30 free transfers. Out of this 30, you can have 20 cPanel to cPanel transfers and 10 Manual Transfers, or any combination of the two that totals 30 or less websites. Another example: A Pro Dedicated server includes unlimited cPanel to cPanel transfers, this means you can have 150 sites (or even more) moved. Also since there is an unlimited total number of transfers, you can utilize up to 100 Manual Transfers. However, that being said, we do require all customers to be fully compliant with our Terms of Service and to only utilize disk space and bandwidth in the normal operation of a personal or small business website.
