file-permissions

问题 I am writing a PHP code that creates another PHP file with fopen and writes to it. It runs on most shared environments without any problem but in some old servers and customized servers the code fails to create file and write to it even though the folder permission is 755 as the PHP runs under the account 'nobody' and the folder owner is another user. In shared servers the folder owner and the PHP both runs under same user and so there are no permission issues. Can anyone help me out here

问题 Rummaging around some directories using Terminal on my OS X machine, I've discovered that many files (mostly old .doc , .xls , .jpg and even some .url files) have permissions -rwx------+ rather than the more common (and expected) -rw-r--r--+ or -rw-r--r--@ I'm unclear why this should be the case. Most of the offending files are older (some quite old, perhaps from the dark days when they resided on a Windows machine) and there have been many migrations and updates since their creation. So, is

问题 When I plug a USB stick/thumbdrive that has been formatted as FAT32 into a Raspberry Pi (running Raspbian) the file permissions default to 644 and I cannot change them. I need to leave the stick as FAT32 so it can be used back and forward to a Windows system. I have written a rule using udev but I can't get it to work. My udev rule looks like this: # Set up any USB stick for full write access KERNEL=="sd?1", MODE="0777" I determined that the rule is getting triggered because I had it renaming

问题 I have a UWP app that requires the restricted capability "broadFileAccess" to access data from a file. I also have to use "runFullTrust" capability for registry access. My understanding was that an app in "runFullTrust" mode had both file and registry access permissions and that "runFullTrust" is a higher level capability. Problem: I tried giving "runFullTrust" capability,but for some reason the file access permissions are denied and also I dont even have an option to enable it under Settings

问题 I have a Xubuntu install running in a VM (VirtualBox) on a Windows 10 host. There is a directory on the Windows file system which I have mounted in the guest as a vboxsf. I think it's a Linux problem but that's the background in case it's relevant. I have write access to this directory and all files within it (everything is -rwxrwxrwx). I can create, modify and delete files and directories in it. But trying to create a soft link (ln -s) or chown a file or directory to a different owner

问题 I am using the following code to determine if I can write to a specific directory using QFileInfo: QFileInfo dinfo(dirname); if (dinfo.exists()) valid = dinfo.isWritable() Unfortunately, when I pass in the path of the current user's desktop on Vista 64: C:\Users\USERNAME\Desktop QFileInfo::isWritable() returns false. However, if I pass it another directory (say C:\Temp) it returns true. I requested the directory permissions from the QFileInfo object which were 5555 (not writable by anyone).

问题 Since yesterday I haven't been able to generate strong name keys using sn.exe or through Visual Studio which also uses sn.exe. When attempting to generate a key file the following cimmand is executed sn - k "key file.snk" sn.exe then responds with Failed to generate a strong name key pair -- Access is denied. After repeating this process while running Process Monitor I now know that the locations to which sn.exe is denied access all reside within the following directory \ProgramData\Microsoft

问题 We are writing a OneDrive client application using a the REST APIs provided for OneDrive (personal) and need a way to identify the operations supported/allowed on the resource. There's something called activities which lists all the operations that have already been performed on a resource. And the Permission resource provides information about a sharing permission granted for a DriveItem resource. The same is returning a blank array when called:(. So, is there any way to identify what all

问题 Is it possible to use a small .NET page to set folder permissions on some folders on the server where it resides? What is the code or objects that can be used for this? I am on Windows Server 2003. Basically I want to hit the page with a GET or POST and have it run and check and/or update the permissions on a folder. 回答1: There's a number of possible ways to approach this. One is to use the FileIOPermissions class, which allows you to specify permissions on files and folders. The other option
