Would it be possible to compile newer version of vsftp with option delay_failed_login
vsftpd-2.0.5/Changelog:
- Added delay_failed_login and delay_successful_login to help limit resources
taken by brute force attacks.
- Kick session after a few login fails. Allows IP blocking solutions to be more
immediately effective.
I think it will be very very useful and it could solve problems with brute force attacking ftp servers better than fail2ban scripts.
