proftpd-mod-wrap 1.3.7a+dfsg-12 (ppc64el binary) in ubuntu impish

 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 module is contained in the contrib/mod_wrap.c file for ProFTPD 1.2+. It
 enables the daemon to use the common tcpwrappers access control library while
 in standalone mode, and in a very configurable manner.
