In this tutorials i will discuss how to create an FTP server with ProFTP in Linux/Ubuntu Server/Destkop, What is ProFTPD.
ProFTPD is a proven, high-performance, scalable FTP server written from scratch, with a focus toward simplicity, security, and ease of configuration. Naturally, ProFTPD powers some of the largest sites on the Internet. It features a very Apache-like configuration syntax, modules, and a highly customizable server infrastructure, including support for multiple ‘virtual’ FTP servers, anonymous FTP, and permission-based directory visibility.
ProFTPD has been configured and designed to be more secure than WU-FTPD. ProFTPD was rewritten from scratch to provide greater security. The security features that it provides are:

• directory access using .ftpaccess files
• anonymous FTP root directory
• support for hidden files
• self-contained
• uses an unprivileged user in stand-alone mode

To Install FTP Server with Prottpd in Ubuntu Server or Desktop. 1. Install proftpd (Secure way,Open terminal (ctrl+alt+t)with this command :

sudo apt-get install proftpd

2. Add this line in /etc/shellsfile

sudo gedit /etc/shells

to open the file

/bin/false

Create a /home/FTP-shared directory

cd /home
sudo mkdir FTP-shared

Create a /home/FTP-shared directory :

cd /home
sudo mkdir FTP-shared

Create a user named userftp which will be used only for ftp access.

sudo useradd userftp -p your_password -d /home/FTP-shared -s /bin/false
sudo passwd userftp

Example: useradd pr3p -p handsome -d /home/FTP-shared -s /bin/false In FTP-shared directory create a download and an upload directory :

cd /home/FTP-shared/
sudo mkdir download
sudo mkdir upload

Set the good permissions for these directories :

cd /home
sudo chmod 755 FTP-shared
cd FTP-shared
sudo chmod 755 download
sudo chmod 777 upload

Edit proftpd configuration file :

sudo gedit /etc/proftpd.conf

After editing the proftpd configuration file, Save and exit. Server is on port 1980 (in this exemple) and the access parameters are user : pr3p password : the one you’ve set for userftp 3. To start/stop/restart your server :

sudo /etc/init.d/proftpd start
sudo /etc/init.d/proftpd stop
sudo /etc/init.d/proftpd restart

4. To perform a syntax check of your proftpd.conf file :

sudo proftpd -td5

5. After installation you may now try to access your ftp server with your FTP client: I’m using filezilla for ftp client. For more info visit the official site: Ubuntu forum and Proftpd.org
