sydep is a tool for simple deployment over rsync. In combination GIT it is very powerful instrument. It provides three actions: init, push, and pull. init creates config files for sydep in the current directory. These are sydep.cfg, which contains connection details, and .sydepignore, which specifies files to ignore. push uploads files from the working directory to the server. pull downloads existing files from the server. It downloads only those files which are already in the working directory.
Aftpd is an FTP server for anonymous access designed for Unix-like operating systems. It uses an asynchronous model of connection processing and provides service for all users within a single process; can use multiple threads to run more efficiently on multi-core systems, with each thread serving multiple clients simultaneously; uses effective mechanisms of transferring files, minimizing copying of data in RAM (sendfile or a combination of the system calls mmap/writev); uses effective event notification schemes (kqueue on FreeBSD and epoll on Linux); uses poll or select in older systems; and supports IPv6. For safety, it works as an unprivileged user and uses chroot.
