Description |
---|
In UNIX and related computer operating systems, a file descriptor is an indicator used to access a file or other input/output resource, such as a pipe or network connection. File descriptors index into a per-process file descriptor table maintained by the kernel, which in turn indexes into a system-wide table of files opened by all processes, called the file table. As a single-threaded server, Lighttpd must be limited in the number of file descriptors that can be allocated. This will prevent Lighttpd from being used in a form of DoS attack against the operating system. |
