Install vsftpd on Ubuntu 16.04

Installing vsftpd allows you to upload files to a server, the concept is comparable to that of Google Drive.  When you invite specified users to your Google Drive they can create, delete, upload and download files all behind a secure login. Vsftpd is excellent for company’s looking for an alternative to Google Drive or for anyone who wants to create a robust server. This “Very Secure File Transfer Protocol Daemon” is favored for its security and speed and we’ll be showing you how to install vsftpd on an Ubuntu 16.04 LTS server.

 

Pre-Flight Check

  • These instructions are intended specifically for installing vsftpd on Ubuntu 16.04.
  • You must be logged in via SSH as the root user to follow these directions.
Warning:
FTP data is insecure; traffic is not encrypted, and all transmissions are clear text, including usernames, passwords, commands, and data. Consider securing your FTP connection (FTPS).

Step 1: Updating Apt-Get

As a matter of best practices we update apt-get with the following command:

apt-get update

Step 2: Installing Vsftpd

One command allows us to install vsftpd very easily.

apt-get -y install vsftpd

Step 3: Configuring Vsftpd

We’ve installed vsftpd, and now we will edit some options that will help us to protect the FTP environment and enable the environment for utilization. Enter the configuration file using the text editor of your choice.

vim /etc/vsftpd.conf

Change the values in the config file to match the values below and lastly, save exit by typing

:wq

 

anonymous_enable=NO
local_enable=YES
write_enable=YES
chroot_local_user=YES
ascii_upload_enable=YES
ascii_download_enable=YES

 

Click Here for a Further Explaination on Each Directive
Anonymous_enable: Prohibit anonymous internet users access files from your FTP. Change anonymous_enable section to NO.

Local_enable: If you have created users you can allow these users to log in by changing the local_enable setting to YES.

Write_enabled: Enable users the ability to write the directory, allowing them to upload files. Uncomment by removing the # in from of write_enabled:

Chroot jail: You can “chroot jail” local users, restricting them to their home directories (/home/username) and prohibiting access to any other part of the server. Choosing this is optional but if you state YES follow the steps in Step 4 for removing write privileges and making their own directory for uploads. If you select NO, the user will have access to other directories.

Step 4: Editing Permissions for a User

If you have an existing or new user that is not able to connect, try removing write privileges to their directory:

chmod a-w /home/username

Step 5: Creating the User a Directory

Create a directory just for FTP, in this case, and we are name it files. Afterward, this user will be able to upload and create files within the files folder:

mkdir /home/username/files

Step 6: Accepting FTP Traffic to Ports

There are a few ways to open ports within a server, below is one way of opening port 20 and 21 for FTP users to connect.

Note
Directly passing iptable commands, like below, can break some firewalls. In whichever method you choose to edit your iptables ensure that port 20 and 21 are open.

iptables -I INPUT 1 -p tcp --dport=20 -j ACCEPT

iptables -I INPUT 1 -p tcp --dport=21 -j ACCEPT

Step 7: Restarting the Vsftpd Service

Restarting vsftpd enables changes to the file (step 3) to be recognized.

service vsftpd restart

Step 8: Verifying Vsftpd

Now for a little fun, let’s connect to our FTP to verify it is working.

ftp 79.212.205.191

Example Output:

ftp 79.212.205.191
Connected to 79.212.205.191.
220 Welcome to FTP!
Name (79.212.205.191:terminalusername):<enter your FTP user>

You’ll also be able to connect via an FTP client, like Filezilla, using the IP address of your hostname and leaving the port number blank.  Take it for a spin and try to upload a file or write a file. If you enabled the chroot jail option, the user should not be able to go to any other parent directory.

How to Install and Configure vsftpd on CentOS 7

FTP (File Transfer Protocol) is one of the most popular methods to upload files to a server. There exist a wide array of FTP servers, such as vsftpd, you can use and FTP clients exist for every platform.

Essentially no matter what OS you use you can find an easy to use FTP client, so it makes for a great solution to transfer files. On CentOS based servers before you can connect via FTP you’ll have to setup an FTP server. Here we’re gonna setup vsftpd which is a great option since it has a focus on security and speed.

How To Install and Configure vsftpd on Fedora 23

FTP (File Transfer Protocol) is the most common method of uploading files to a server. A wide array of FTP servers, such as vsftpd, and clients exist for every platform.

Pre-Flight Check

  • These instructions are intended specifically for installing the VSFTP server on Fedora 23. If you’re on a different operating system, check out our guides for installing vsftpd on Fedora 22, CentOS 7, and Ubuntu 15.04.
  • We’ll be logging into a Liquid Web Self Managed Fedora 23 server as root.

Step #1: Install vsftpd

Warning: FTP is an insecure protocol. Data is not encrypted, and all transmissions (including usernames, passwords, commands, and the data itself) are in clear text. Consider securing your FTP connection with SSL/TLS.

As a matter of best practice we’ll first update our packages:

dnf -y update

Now we’ll install vsftpd and any required packages:

dnf -y install vsftpd

Step #2: Configure vsftpd

First, we’ll edit the configuration file for vsftpd:

vim /etc/vsftpd/vsftpd.conf

In vim, you can press “a” to enter text insertion mode, and hit the escape key (Esc) on your keyboard to return to command mode. For a refresher on editing files with vim, see New User Tutorial: Overview of the Vim Text Editor. If vim is not installed on your OS, you can follow our tutorial on installing vim at How to Install VIM (Visual editor IMproved) on Fedora 23.

Now, to prevent anonymous FTP access, we’ll change the anonymous_enable setting to “NO”:

anonymous_enable=NO

We do want to allow local users to log in, so we’ll change the local_enable setting to “YES”:

local_enable=YES

If you want local users to be able to write to a directory, you’ll also need to change the write_enable setting to “YES”:

write_enable=YES

For our purposes, we want local users to be ‘jailed’ with no access to any other part of the server. To accomplish that, we simply uncomment the chroot_local_user setting by removing the preceding “#”, so that:

#chroot_local_user=YES

becomes

chroot_local_user=YES

Now save and exit the file with the command:

:wq

At this point, we’ll restart the vsftpd service with the new configuration:

systemctl restart vsftpd

Finally, we’ll set the vsftpd service to start at boot:

systemctl enable vsftpd

That should produce output similar to the following:

[root@host ~]# systemctl enable vsftpd
Created symlink from /etc/systemd/system/multi-user.target.wants/vsftpd.service to /usr/lib/systemd/system/vsftpd.service

Step #3: Allow vsftpd Through the Firewall

Allow the default FTP port, port 21, through firewalld:

firewall-cmd --permanent --add-port=21/tcp

And reload the firewall:

firewall-cmd --reload

Possible Errors

There are a few common vsftpd errors that we’ve already solved for you! Check out the following if you run into issues:
