I have a computer with Linux installed that is being used by several users. Included is a secondary data partition that is being shared between the users. But permissions are not easily handled. Anything created by a specific user, get's that user as owner. I was wondering if it would be possible to use fuse to some how mimic the way Android handled it's /data/media location?
I don't know how Android handles /data/media permissions and my solution does not involve FUSE, but if you create a group and add all users in it and set setgid bit on the root of the secondary file system and change it's group to group with all users then owner of each file will still be user that created the file but group of the file will contain all user and therefore they can access it if you set permissions on that file right (something like 660).

I'm running Raspbian Lite on a Raspberry Pi 2. I'm trying to have vsftpd set up with one user called admin to have root access for FTP, while all other users (such as filetransfer) get redirected to their home directory. Any help would be greatly appreciated :)
I gather you're using vsftpd's chroot_local_user setting to keep users within their home directories. If that's enabled, you can use the chroot_list_file setting to pass a file containing the users you don't want to be locked in their home directories.
You can find out more on the vsftpd manual page.

I have a Ubuntu 12.04 machine that I can only access using SSH. On this machine I have two users and I want to limit the access to certain files to one of these users.
Basically I want that user to be able to access only its home directory and nothing more. I know that by removing the rx permissions to other home directories for others is one option but I wanted to know if there is another way, a configuration file where I can tell that my user can only have access to that folder.
Thanks.
chrooted jail is the answer.

Since I am not that experienced with Linux this might be an easy, if not too simple question for you. Recently I met an old friend of mine and I want to exchange some files with him. In fact I could send the files by E-Mail or share them by Dropbox or something like that but I want to make use of Linux and my RaspberryPi.
Here, the RaspberryPi can be accessed via SSH and I want my friend to be able to access one specific directory. The one where I place the files.
I don't want him to mess around in the system. Ideally he should be able to only see this one directory.
Is it enough if I create a user and put the files in his home directory?
Thanks in advance
See this introduction to permission management on Linux.
To answer your Question:
Is it enough if I create a user and put the files in his home directory?
Yes, but it's not a perfect solution because the home folder of an user contains some subfolders.

We have smb mount point in one of our RHEL server. By logging as normal user, any file or directory created by the user is shown as root:root. What configuration has been made to force user and group shown as root:root always ? I have checked /etc/samba/smb.conf, no configuration has been found. And also all file and directory getting created by normal user has full 777 permission. Appreciate any quickest help.
The userid/gid "owning" a particular mounted SMB partition are determined by its mounting configuration.

Is this possible?
I have an issue granting a user access to website via FTP. The user can access them but cant delete or edit the files. I would like to change the permissions for the group so any user belonging to the group can edit those files but preserve (keep) the permissions for user / world.
Thanks in advance,
Joseph Mituzas
The command
chmod g+r filename
will merely add group read permissions to the file and not affect user or world permissions. The command
chmod g=rw filename
will replace the current group permissions with read/write.
Neither of these commands will affect user and world permissions
