bsdproxy is an event-driven TCP proxy for FreeBSD which uses the kqueue(2)/kevent(2) API in the event loop. It can be used to proxy any communication between a server and its clients which takes place over a TCP connection. It was mainly written to serve as an example of the uses of FreeBSD kernel event queues for event-driven I/O.
BSDftpd-ssl is a secure and easy-to-use FTP server that supports industry standard TLS/SSL encryption and authentication for whole FTP sessions and data transfers. This implementation supports both the original FTP protocol and the RFC2228-compliant TLS/SSL enhancement. The package contains the secure FTP server (named "ftpd") and a command line TLS/SSL-aware FTP client (named "ftps"). The server's features include logging of transfers, changing of a session root (known as "chroot"), and virtual host support.
