Installing vsftpd on Ubuntu or Debian

sudo apt-get install vsftpd

Installing vsftpd on CentOS / Fedora

yum install vsftpd

How to configure vsftpd

Now that you’ve installed vsftpd, follow this procedure to configure it. These steps applies for both the linux variants.

Before you get started, stop the vsftpd by typing

service vsftpd stop

Edit the vsftp.conf

1. In Ubuntu / Debian:

vi /etc/vsftpd.conf

2. In Red Hat / CentOS

vi /etc/vsftpd/vsftpd.conf

Make the following changes:

We don’t want anonymous login:

anonymous_enable=NO

local_enable=YES

write_enable=YES

connect_from_port_20=NO

chroot_local_user=YES

local_umask=022

Now that basic configuration is complete, now let us begin with locking / securing a directory to user.

sudo useradd -d /var/www/path/to/your/dir -s /usr/sbin/nologin ftpuser

Setup a password for the user:

sudo passwd ftpuser

In order to enable the ftpuser read and write the data in your home dir, change the permission and take ownership:

sudo chown -R ftpuser /var/www/path/to/your/dir
sudo chmod 775 /var/www/path/to/your/dir

Create userlist file and add the user:

1. Ubuntu / Debian:
vi /etc/vsftpd.userlist

2. CentOS / Fedora

vi /etc/vsftpd/vsftpd.userlist

Add the user:

ftpuser

Save the file and open the vsftp.conf file again:

vi /etc/vsftpd.conf

Add the following lines at the end of the file and save it:

# the list of users to give access
userlist_file=/etc/vsftpd.userlist

# this list is on
userlist_enable=YES

# It is not a list of users to deny ftp access
userlist_deny=NO

After completing all these procedures it is almost ready to use it, give it a try but you will get a 500 OOPS permission denied error. To fix it you need to add a nologin to the shell set.

vi /etc/shells

The file should look like this:

/bin/ksh
/usr/bin/rc
/usr/bin/tcsh
/bin/tcsh
/usr/bin/esh
/bin/dash
/bin/bash
/bin/rbash

Add this line at the end:

/usr/sbin/nologin

Now create a usergroup and add the ftpuser to it:

sudo addgroup ftpusers
sudo usermod -Gftpusers ftpuser

Now start the vsftpd:

service vsftpd start
