1. a simple secure efficient FTP server This is twoftpd, a new 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 were two parts to the server -- an authenticating front end, which contains no file or data transfer code, and a back end, which contains all the data transfer code.
