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.

When moving files between filesystems that have permissions and those that do not, the user home directory is populated with files of all sorts of permissions. UFPM (Uniform File Permission Modifier) has been designed to modify all files and directories to have a uniform permission set based upon their file type.
CloudLinux is a Linux operating system designed to improve control in the shared hosting and data center arena, while simultaneously increasing control and stability, as well as improving overall performance. It employs kernel level technology called LVE to allow Web hosting companies to control QoS of each individual Web site as well as each section of the Web site. The technology can be used for any multi-tenant environment, where it is beneficial to control resource usage of individual tenant. With CloudLinux, hosting companies can make sure that a single site cannot slow down or take down other Web sites. The OS is interchangeable with CentOS.
ptee is a Unix shell tool similar to tee, but it allows you to invoke multiple sub-shells in parallel. Standard input to ptee is copied to both normal standard output and to each sub-shell running under ptee. Each sub-command is run concurrently and fed the same input. The output of each sub-command is thrown away, but any shell expression can be used, such as redirecting to a file. Note that there are some limits on ptee. The shell pipeline will only execute at the pace of the slowest sub-command; otherwise large amounts of data would have to be buffered. Also, the shell that ptee invokes requires 'sh'-like semantics, such as supporting the -c option.
