Jailing Ftp user in VSFTP - locking user in their home directory

In this post we going to see about how we are going to jail a ftp user in VSFTP.  Jailing means that user is locked to their home directory, can't able view or access any other folder in that server.

Jailing is mainly done for security purpose. If the user is not jailed, so they can able to access all other folder and files, can download the main configuration files in that server which is not secured one.

First install VSFTP package in server.

[root@linuxstorages~ #] yum install vsftpd

[root@linuxstorages~ #] chkconfig vsftpd on

Create a user with directory which you need to jail.

[root@linuxstorages~ #] useradd -d /var/www/html username

[root@linuxstorages~ #] passwd username

Now change the configuration for VSFTP

  [root@linuxstorages~ #] vi /etc/vsftpd/vsftpd.conf

     Go to line 96 and enable the below line

     chroot_local_user=YES

     :wq (save)

[root@linuxstorages~ #] /etc/init.d/vsftpd restart

Now check by login via filezilla or terminal using 21 port.
