file-permissions

Hiya all thanks in advance for any help you can provide. I am using C9.io, node, express, multer, gridfs-stream. And Im getting: /home/ubuntu/workspace/node_modules/multer/index.js:25 mkdirp(dest, function(err) { if (err) throw err; }); Error: EACCES, mkdir '/uploads' I run the server.js script and that is the error that I get. I believe is something to do with permissions but i have tried chown the public folder and chmod ax, you guys have any other suggestions as to what to do?. Still get same error. The code I have is server.js app.use('/uploads', express.static(__dirname + '/public/uploads

I can use stat() to figure out what permissions the owner, group, or others have and I can use geteuid() and getpwuid() to get the user name of the process. I'm not quite sure how to get the groups a user belongs to without a system call though. Even knowing how to get the groups, it seems like a lot of work to integrate all of this information. Is there an easier way? The access() POSIX function can check the permissions without opening it. However, it needs to a syscall. The access() function shall check the file named by the pathname pointed to by the path argument for accessibility

I would like to do the following: Non-admin users can run my program without UAC prompt. The program have full access to a particular file. Outside of the program, the user have read-only or no access to the file. They cannot modify the file. They can only modify it through the program. Is it possible? Harry Johnston You'll need to split your code into two parts; the user interface, which runs in the user's context, and a service, which runs with admin privilege. If you're programming in C, start with the MSDN library section on services for a general overview as well as the authoritative

Given a struct file, is it possible to get the associated file descriptor in linux kernel space? I am trying to change permissions using either sys_chmod or sys_fchmod. One takes a file descriptor the other expects a filename from user space. I can figure out how to get the filename but how would I cast it to a user space pointer? Thanks The function you're after is chmod_common : static int chmod_common(struct path *path, umode_t mode) Which takes a path and the mode you want to set. Unfortunately, as you noticed, it's static and obviously not exported. So you could go multiple ways:

There is a config setting in git that is named core.sharedrepository and which to my understanding impacts the way that git deals with file permissions. My question is what files are meant? Assuming my git repo is at /home/user/project the files in the /home/user/project/.git subfolder? the code files /home/user/project/ but not .git? all files /home/user/project ? the background to my question is that the files in /home/user/project/.git are created world readable -rwxrwxr-- . I would like to have all files only accessible to either the specific user or at least a groupid member The setting

I use git to pull changes os a site's code base. The changes inside files and deletion of files works, however, when I add new files or directories (not empty ones) to the repo, it wont get pulled locally to the webserver, when pulling no error message is displayed but when checking for that file, it is not there. Online at the bitbucket repo it is shown. Tried to delete the local git repo and clone it again, this way I get all the files from origin, but the problem persist when doing a pull for newly added file. It shows as if its pulled: ... 18bb8ac..c9c1e40 master -> origin/master Updating

I'm trying to create a php file which I can edit straight away without manually set the permissions. I'm trying this... <?php $var = '<?php $mycontent = new Content(); echo $mycontent->block($p_name);?>'; $myFile = "testFile.php"; $fh = fopen($myFile, 'w+') or die("can't open file"); $stringData = $var; fwrite($fh, $stringData); fclose($fh); ?> ...it creates the file, but when I try to edit the file in my IDE it won't let me of course. I have to manually set the permission of the file created. Is there any way I can create the file and have the permission already set? Thanks in advance Mauro
