This article will explain in detail how to configure ProFTPD in Ubuntu. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

What is ProFTPD

ProFTPD is a FTP server program popular in UNIX-like systems, which is similar to vsftpd, WU-FTP and other functions.

[official website] http://www.proftpd.org

Second, install ProFTPD

$sudo apt-get install proftpd

Add ftp groups and users

$groupadd ftpg

The / /-d parameter indicates the default directory

$useradd ftpu-d / Data/webapps/-g ftpg

/ / set password

$passwd ftpg

Use the Ftp client tool to test the connection:

The connection was successful.

4. Modify the user chroot

The connection is successful but the root directory of the user ftpu, that is, chroot, is not limited, and the user can also access the parent directory.

/ / modify proftpd configuration file

$vi / etc/proftpd/proftpd.conf

/ / remove the comments before the following lines #

# DefaultRoot ~

/ / restart proftpd

$/ etc/init.d/proftpd restart

Fifth, prohibit user terminals from logging in

/ / Edit / etc/passwd

$vi / etc/passwd

Ftpu:x:1006:1004::/Data/webapps/:/bin/sh

Modify to

Ftpu:x:1006:1004::/Data/webapps/:/sbin/nologin

After restarting proftpd, the ftp client prompts that it cannot connect:

-

530 Login incorrect.

-

After inspection, it is found that there is no / sbin/nologin in the shells list of the current system.

/ / add / sbin/nologin support

$vi / etc/shells

/ / add a line to the document

/ sbin/nologin

Restart proftpd, complete.
