I have a few FTP users on my linux server(running vsftpd). They all have their own directory and can upload and delete files in that folder.Now, I was wondering whether it would be possible to create special permissions/rights for users. For example, I would like to make it so that certain users could not upload .exe files, or I want a certain user to only be able to upload image files (gif, jpg).

The security issue is public users are able to upload files on to my server via the website. They could even access the root and execute whatever they want on the server.
I have consulted with 2-3 Linux experts. According to them, the PHP user has rights to execute anything on the server or upload & store files in whichever folder they want.
Can I protect my folders to avoid file uploads via the website. The application has security vulnerabilites. However, I want to prevent hackers to enter my site until the vulnerabilities are fixed.

I have Unbuntu 2.32.1 Build date 14/4/11 I have Samba Installed I also have 8 Sata drives all with NTFS most of them have a lot of data on them. All my drives were used on an old windows 7 system, and now I wish to have them in a server setup.
My clients are all windows users apart from 1 witch is an Unbuntu desktop user. The problem I have is access rights or permissions none of the clients can gain access to my NTFS shares. I am using a GUI on my server (Gnome) as I am not very clued up with command lines in Unbuntu just yet.
I have just started using linux. I have setup an ubuntu apache2 server. It has been running brilliantly and I am highly impressed with the Linux system. My box is an HTTP server and I am hosting a website on it. I have VSFTPD installed and functioning as my FTP software. It has worked fine so far but I have been a bit annoyed that I have had to set permissions for each file I have put on there.
Now I have run into a serious issue with the permissions being set to 600 and I really need them to 755 because I am running an automatic upload for a webcam and the Image can't be accessed due to the automatic permissions of 600 being set to the image. My extensive windows background tells me that I need to apply the correct permissions to the WWW folder and get the files to inherit these permissions automatically.
I'm struck with the following problem.

I'm running Ubuntu 10.04 LTS Using sftp, is there any way to force particular file permissions upon upload? I want the permissions on all files uploaded via sftp to be 664.
I've searched around and cannot find an answer. Many people ask similar questions and many responses recommend using umask, but as far as I understand it, umask is just a bit mask--it cannot be used to set permissions.

I'm new to Ubuntu and wish to use the system in combination with Apache/mySQL/phpMyAdmin. I managed to get phpMyAdmin working for now. Also mySQL database seems to work. Only problem is Apache2. I can start the server and it is working. However in the folder /var/www/ where all site files are stored, I can not edit anything. I have been reading about sudo nautilus which did allow me to change administrator rights for the folder, but still I do not get it working to display other than the default index.html page. Is there a manual or quick solution for me so I can use apache with Ubuntu?

I am trying to set up a simple home file-server for media and backups, using an old Atom board I had lying around and 1GB memory, so I don't want a full desktop. All goes well with installing server 10.10, using LVM for my data disk. However, I wanted some GUI tools since I am not familiar with the CLI, so I installed gdm, xorg, and gnome-core as suggested in some threads and forums.So far so good, it boots into the Gnome desktop, but I can't get sudo access with anything (synaptic, gkedit, etc.) - always "incorrect password". I am fine from the console; I reset my user password, no luck; I set up another admin user, and that also works in console but not the desktop.I have no idea where to go next and can't find anything that works in the forum

View 8 Replies View RelatedQ: How do I mount a CIFS share so that my user stevej has all rights to it?
Summary: I can mount the share as root.
mount.cifs //10.x.x.x/Data /home/stevej/Synology/Data/ --verbose -o user=stevej
Using Dolphin in Super-User mode, I can copy files and directories from the share to itself with no errors. Using Dolphin in Normal-user mode. I get the failure "Could not change permissions for...". The file is copied, but its owner,timestamp and permissions are wrong. If a subdirectory is involved, the copy aborts.
Using Windows XP I can copy files and directories from the share to itself with no errors.
Testing: If I mount with uid and gid, then my normal user can not access the share.
mount.cifs //10.x.x.x/Data /home/stevej/Synology/Data/ --verbose -o user=stevej uid=stevej gid=users
[code]...
Synology DS211 - There are 2 users on it. One of which is stevej and the other is julie. Rights RWX are applied to the users and the group called users. All files have stevej as the owner and users as the group with RWX Opensuse 11.4 - There are 2 pc's. One is run as stevej. The other pc runs as julie Windows 2000 - Runs as stevej and maps to the share as stevej.
Works as expected Windows XP - Runs as julie and maps the the share as julie. Works as expected Ultimately, I want the shares to automount at boot, or login and give the user full access. I have been to Swerdna's page and done as much as I can, but still no luck.
