4 ProFTPD grew from a desire for a secure and configurable FTP server. It was
|
|
al@19741
|
5 inspired by a significant admiration of the Apache web server. Unlike most
|
|
al@19741
|
6 other Unix FTP servers, it has not been derived from the old BSD `ftpd` code
|
|
al@19741
|
7 base, but is a completely new design and implementation.

9 ProFTPD's extensive configurability provides systems administrators great
|
|
al@19741
|
10 flexibility in user authentication and access controls, including virtual users
|
|
al@19741
|
11 and easy `chroot()` FTP sessions for individual users.

13 ProFTPD is popular with many service providers for delivering update access to
|
|
al@19741
|
14 user web pages, without resorting to Unix shell accounts.
