How to Install and configure ftp server on Ubuntu 16.04

 

FTP stands for File Transfer Protocol, It requires a TCP/IP network framework to function properly. So as the name suggests, FTP is a protocol for transferring file or data from the server to the client. In here we will configure ftp server on a ubuntu distribution. The reason behind that, we will provide a secure channel for transferring data from server to client.

So few things we need to keep in mind before getting started. please find the details below.

  1. We have used Ubuntu 16.04 server to configure ftp server.
  2. IP – 10.100.98.48/16
  3. We have changed the default FTP port (21) to 2189 for security purpose.
  4. User has been created as “ftp-user”
  5. The directory used “/ftp-test”

 

 

 

Now let’s configure ftp server

[email protected]:# apt-get update && upgrade -y
[email protected]:# apt-get install proftpd -y

in between you will get a prompt like this...

configure ftp server on ubuntu

[email protected]:# ufw disable
Firewall stopped and disabled on system startup

Create a directory so that FTP client can access to that particular directory only.

[email protected]:# mkdir /ftp-test
[email protected]:# cd /ftp-test
[email protected]:/ftp-test# touch abc.txt
[email protected]:/ftp-test# ls
abc.txt

 

Add a user and give permission for a specific directory while you configure the FTP server. So that whenever anyone connects using these credentials, they can have access to that particular directory.

[email protected]:# useradd -d /ftp-test -s /bin/nologin ftp-user
[email protected]:# passwd ftp-user
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully

 

Make sure proftpd service starts as a systemd service.

[email protected]:# systemctl enable proftpd
proftpd.service is not a native service, redirecting to systemd-sysv-install
Executing /lib/systemd/systemd-sysv-install enable proftpd

[email protected]:# systemctl start proftpd

 

Now edit the config file and make necessary changes.

[email protected]:# vi /etc/proftpd/proftpd.conf

# /etc/proftpd/proftpd.conf -- This is a basic ProFTPD configuration file.
# To really apply changes, reload proftpd after modifications, if
# it runs in daemon mode. It is not required in inetd/xinetd mode.
#

# Includes DSO modules
Include /etc/proftpd/modules.conf

# Set off to disable IPv6 support which is annoying on IPv4 only boxes.
