Disable Delete Permission Vsftpd For Specific User

Disable Delete Permission Vsftpd

In this article, we are going to understand how to disable or remove delete permission for any specific vsftpd user. This is a very important configuration which helps or saves you from sudden deletion of files.

We have faced this issue and we want to disable the remove/delete permission for the specific user. After long hours of searching on google did not find any solution. When we dig into the vsftpd man pages that time we came to know about this solution. After successful testing, I have shared this on techthings.

If you do not install vsftpd on the system then follow my previous guide on VSFTPD installation and configuration.

Let’s check the step-by-step configuration to disable delete permission for vsftpd user.
user_conf_dir” is the powerful option allows you to disable delete permission.

Step 1: Create a vsftpd_user_conf directory

Create “vsftpd_user_conf” directory under the “/etc/vsftpd“. This directory contains the configuration file for vsftpd user.

$ mkdir -p /etc/vsftpd/vsftpd_user_conf

Step 2: Configuration file

Now create a configuration file for vsftpd user with the username. Here I have created testuser on the system. I have created “testuser” file under the “/etc/vsftpd/vsftpd_user_conf”. This “testuser” file used to add the entries which disable the delete/remove permission for vsftpd user.

$ vim /etc/vsftpd/vsftpd_user_conf/testuser
##Disable delete commands

save and close the file.

Step 3: Add Configuration in Vsftpd.conf

Now open “vsftpd.conf” and add the below entry to the end of the file. Reload the vsftpd service.

vim /etc/vsftpd/vsftpd.conf

# if you don't want to give access to user use /home/$USER then you can
# use following param to use different home dir
# local_root=/home/vsftpd/$USER
# user_sub_token=$USER

Reload Vsftpd Service:
$ /etc/init.d/vsftpd reload

Step 4: Test

Login from the terminal with ftp user and then try to delete a file with that user. You will get “550 Permission denied.” error.

root@staging:/etc/vsftpd/vsftpd_user_conf# ftp

Connected to
220 (vsFTPd 3.0.2)

331 Please specify the password.
230 Login successful.

226 Directory send OK.

550 Permission denied.

That’s it now your files are protected.
