Few weeks ago we showed you how to install VSFTPD in Ubuntu. We also said because FTP implemented in its standard form is inherently insecure, it’s recommended to enable FTP over SSL/TLS encryption or secure FTP (SFTP).

This brief tutorial is going to show you how to secure your FTP communication by using encryption. FTP communications that are not protected with encryption make it possible for someone with the right tools who sits on your network to intercept and retrieve vital information.

Secure FTP helps prevent this type of attack and protects your data while in transit. If you haven’t already implemented secure FTP, then it should be one of your most important tasks to do if you want to secure your online servers.

To get started with securing VSFTPD server in Ubuntu, continue below. We’ll will show you how it’s done and how to using FileZilla FTP client to connect to the server.


  • Installing VSFTPD in Ubuntu 14.04

First, go ahead and install VSFTPD server in Ubuntu. To do that, run the commands below.

sudo apt-get update && sudo apt-get install vsftpd


Next, open VSFTPD default configuration file and make these changes below. Go line by line and make these changes starting with disabling anonymous login.

Open VSFTPD configuration file by running the commands below

sudo vi /etc/vsftpd.conf


Anonymous login allows anyone to connect to your FTP server without authentication. To disable that, change the parameter below to NO



Next, enable local user with accounts on the server to logon to the FTP server. To do that, change the parameter below to Yes.



Next, make sure that users with accounts have write access on the server. This means that users will be able to create/delete folders, and add content when they logon.

To make that change, set the parameter of the line below to Yes.



If you also want local account users to only work or jailed in their own home directory and don’t want them navigating to other parts of the server, you should change the line below to Yes.



After that, save the file and continue to the next step.


  • Creating And Applying the SSL Certificate


After making the changes above, lets go and create our encryption key or certificate to use to connect to the server. First, create a folder that will be used to store the keys.

To do that, run the commands below.

sudo mkdir /etc/ssl/certificates


Then run the commands below to create the encryption key that will last for 365 days.

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/certificates/vsftpd.pem -out /etc/ssl/certificates/vsftpd.pem


After creating the key, go and change add and change these parameters in the default VSFTPD configuration file.

sudo vi /etc/vsftpd.conf


Add / modify the changes below at the end of the file and save.



Save the file and restart VSFTPD server.

sudo service vsftpd restart


  • Connecting Using FileZilla

Next, open FileZilla and create a new profile. Create the profile as shown below. For encryption, select Require explicit FTP over TLS

Accept the unknown certificate to continue
