Setting up Virtual user with VSFTPD with Different Permissions

If you want to  setup a virtual user with  VSFTPD and also want to  share the same directory across multiple users then you can refer the below simple steps to achieve this :

  • Install VSFTPD  server
yum install vsftpd
  • Open the /etc/vsftpd/vsftpd.conf file and add the below contents :

save and quit

Here pasv_address= is explicitly used to map the nat IP  to  public IP for passive port

  • Now go  to  directory /etc/vsftpd/vsftpd-virtual-user/ and create the file :: vsftpd_user
    cd /etc/vsftpd/vsftpd-virtual-user/

    Note :: You need to  create the directory : /etc/vsftpd/vsftpd-virtual-user/ if it doesn’t exist

  • In vsftpd_user file add the usernames for which you want to set per user  configuration
[email protected]~[#] cat vsftpd_user
  • Now create the usernames file as ::
[email protected]~[#] cat test

Here, deny_file will limit the access to specific files and folders for user test and same will be used for hiding the files

To use the benefit of share/common directory add the users as ::

First create a group called :  ftp_users

then add the users as ::

useradd -d /home/share-drive -s /sbin/nologin username

Once done that, use the command usermod -G ftp_users test this will facilitates all the files and folders creation with test:ftp_users .

To  add new user use :
 useradd -d /home/share-drive -s /sbin/nologin -g  ftp-users test1

Finally,  restart the VSFTPD service and you are done.
