Default pure-ftpd settings store logs thru ‘syslog’. Thanks to this we can forward logs inside syslog/rsyslog.
# inside /etc/syslogd.conf file find: *.*;mail.none;news.none -/var/log/messages #add ftp.none: *.*;ftp.none;mail.none.news.none -/var/log/messages #add new line for ftp: ftp.* /var/log/ftp
