tnftpd is the a server for the Internet File Transfer Protocol (ftp). The server uses the TCP protocol and listens on the port specified in the ``ftp'' service specification; see services(5). `tnftpd' is a portable version of the NetBSD ftpd, hence the name. It was formerly known as `lukemftpd'. Various features such as the ftpd.conf(5) functionality, RFC 2389, and draft-ietf-ftpext-mlst-11 support was implemented in NetBSD 1.3 and later releases by Luke Mewburn . tnftpd provides around 90% of the functionality of wuftpd, but in approximately 30% of the footprint.
