Ristrict FTP user not to delete own data

How to Configure FTP Server

Create a ftp user in linux

#useradd shahzad
#passwd shahzad

now use chattr command to prevent user not to delete threir own data

#/usr/bin/chattr -R +a /home/shahzad/*


Note: It will prevent user for deleting their own data, but when you will notice that user is able to delete data from under subfolder. Hence you will need to run this command using cron job so that in every second, recursively it prevent user not to delete data from any location.


set cronjob

#crontab -e
*/1 * * * * /usr/bin/chattr -R +a /home/shahzad/*


unset the permission if require for single file or directory

#/usr/bin/chattr -R +a /home/shahzad/file_name


unset all data

##/usr/bin/chattr -R +a /home/shahzad/*
