How to Set Up an FTP Server on an Ubuntu VPS

Setting up your own FTP server might sound complicated, but it’s actually easier than you think! Think of an FTP server as your personal digital file cabinet that you can access from anywhere. Whether you need to share files with your team or back up important documents, having your own FTP server gives you complete control over your data.

What Is FTP and Why Do You Need It?

File Transfer Protocol (FTP) is like having a super-powered file sharing system. It’s been around for decades and remains one of the most reliable ways to move files between computers over the internet. FTP works with something called TCP/IP protocol – don’t worry, that’s just tech speak for “the way computers talk to each other”.

You’ve probably used cloud storage services before, right? Well, FTP is similar, but you own and control everything. No monthly fees, no storage limits imposed by others, and complete privacy for your files.

Why Choose vsftpd?

For this guide, we’ll use vsftpd (Very Secure FTP Daemon) – and yes, it really is very secure! This software is specifically designed for Ubuntu and other Linux systems. It’s fast, reliable, and has built-in security features that protect your files from unwanted access.

What You’ll Need Before Starting

Here’s what you need to get started:

• An Ubuntu VPS (Virtual Private Server) – CreativeON offers some of the best VPS in Pakistan with excellent support
• Basic command line knowledge (don’t worry, we’ll walk you through each step!)
• About 30 minutes of your time
• A cup of coffee (optional, but recommended!)

Quick tip: If you’re looking for a cheap VPS in Pakistan, CreativeON provides affordable options without compromising on quality. We’ve been serving prominent Pakistani brands like City42, Channel 24, and Chughtai Lab for over two decades.

Step 1: Install vsftpd on Your Ubuntu VPS

Let’s start by getting your system ready and installing the FTP server software.

First, update your system to make sure you have the latest packages:

bash

sudo apt-get update

This command refreshes your system’s package list. Think of it like checking for the newest versions of apps on your phone.

Now, install vsftpd:

bash

sudo apt-get install vsftpd

When prompted, type Y and press Enter to confirm the installation. The system will download and install everything you need.

Once installation is complete, make a backup of the original configuration file (trust me, you’ll thank yourself later):

bash

sudo cp /etc/vsftpd.conf /etc/vsftpd.conf.original

Step 2: Configure Your Firewall

Your Ubuntu server has a built-in firewall called UFW (Uncomplicated Firewall). We need to tell it to allow FTP connections.

First, check if UFW is installed:

bash

sudo ufw status

If you see an error message, install UFW:

bash

sudo apt-get install ufw

sudo ufw enable

Now, let’s open the necessary ports for FTP:

bash

sudo ufw allow OpenSSH

sudo ufw allow 20/tcp

sudo ufw allow 21/tcp

sudo ufw allow 990/tcp

sudo ufw allow 40000:50000/tcp

Here’s what each port does:

• OpenSSH: Keeps your SSH connection working (you need this to manage your server!)
• Ports 20 & 21: These are the main FTP communication channels
• Port 990: Allows secure TLS encrypted connections
• Ports 40000:50000: Reserved for passive FTP connections

Step 3: Create a User Directory

For security reasons, we’ll create a specific user for FTP access and limit where they can go on your server.

Create a new FTP user:

bash

sudo adduser ftpuser

Replace “ftpuser” with whatever username you prefer. The system will ask for a password and some basic information – fill these out as needed.

Now, let’s create a secure directory structure. This is like building a safe room inside your house where FTP users can only access certain files:

bash

sudo mkdir /home/ftpuser/ftp

sudo chown nobody:nogroup /home/ftpuser/ftp

sudo chmod a-w /home/ftpuser/ftp

Create a folder where files can actually be uploaded:

bash

sudo mkdir /home/ftpuser/ftp/files

sudo chown ftpuser:ftpuser /home/ftpuser/ftp/files

Let’s add a test file to make sure everything works later:

bash

echo “Welcome to your FTP server!” | sudo tee /home/ftpuser/ftp/files/welcome.txt

Step 4: Configure vsftpd Settings

Now comes the fun part – configuring your FTP server! Open the configuration file:

bash

sudo nano /etc/vsftpd.conf

Look for these settings and make sure they’re set correctly:

text

anonymous_enable=NO

local_enable=YES

write_enable=YES

chroot_local_user=YES

At the bottom of the file, add these important settings:

text

user_sub_token=$USER

local_root=/home/$USER/ftp

pasv_min_port=40000

pasv_max_port=50000

userlist_enable=YES

userlist_file=/etc/vsftpd.userlist

userlist_deny=NO

Save the file by pressing Ctrl + X, then Y, then Enter.

Create a user list and add your FTP user:

bash

echo “ftpuser” | sudo tee -a /etc/vsftpd.userlist

Restart the FTP service to apply your changes:

bash

sudo systemctl restart vsftpd

Step 5: Add SSL/TLS Security

Here’s where things get really important – we need to encrypt your FTP connections. Without encryption, anyone could potentially see your files as they transfer.

Generate an SSL certificate (think of this as creating a secure lock for your data):

bash

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

The system will ask for some information about your organization. You can fill this out with your details or just press Enter to use defaults.

Now, let’s tell vsftpd to use this certificate. Open the configuration file again:

bash

sudo nano /etc/vsftpd.conf

Add these security settings at the bottom:

text

rsa_cert_file=/etc/ssl/private/vsftpd.pem

rsa_private_key_file=/etc/ssl/private/vsftpd.pem

ssl_enable=YES

allow_anon_ssl=NO

force_local_data_ssl=YES

force_local_logins_ssl=YES

ssl_tlsv1=YES

ssl_sslv2=NO

ssl_sslv3=NO

require_ssl_reuse=NO

ssl_ciphers=HIGH

Save the file and restart vsftpd:

bash

sudo systemctl restart vsftpd

Step 6: Test Your FTP Server

Time to see if everything works! You’ll need an FTP client like FileZilla (it’s free and works on Windows, Mac, and Linux).

In FileZilla:

1. Click Site Manager
2. Click New Site
3. Enter your server’s IP address in the Host field
4. Choose Require explicit FTP over TLS for encryption
5. Select Ask for password as the logon type
6. Enter your FTP username
7. Click Connect

You’ll be asked for your password, and then you should see a certificate warning (this is normal for self-signed certificates). Accept it, and you should be connected to your secure FTP server!
