twoftpd

Simple, secure, efficient FTP server

Twoftpd is an FTP server that strives to be secure, simple, and efficient. None of the commands can cause execution of other programs, and the normal model of execution does a chroot to the logged in user's directory immediately after authentication. The name "twoftpd" comes from the fact that there are two parts to the server: an authenticating front end, which contains no file or data transfer code, and one of two back ends, which contain all the data transfer code.
