proftpd-basic - 1.3.6-4+deb10u6 main

ProFTPD is a powerful modular FTP/SFTP/FTPS server. This File Transfer
Protocol daemon supports also hidden directories, virtual hosts, and
per-directory ".ftpaccess" files. It uses a single main configuration
file, with a syntax similar to Apache.
.
Because of the advanced design, anonymous-FTP directories can have
an arbitrary internal structure (bin, lib, etc, and special files are
not needed). Advanced features such as multiple password files and
upload/download ratios are also supported.
.
This package contains the daemon and all main modules used for
common configurations. If you need database-centric authentication
install the suitable proftpd-mod suggested package.
