|4.2.10. Sockets created by innd or clients|
The innd server and its clients (most notably ctlinnd) create Unix- domain sockets or named pipes. They are created inside a ``firewall'' directory that gives access permission to a limited set of users. For example, assume the directory is /usr/local/news/innd and that it is owned by user news in group news and has mode 0770. Using these permissions, then only members of the news group can use ctlinnd to create new groups because only they will be able to send a message to the innd socket. This directory (which is specified by the _PATH_INNDDIR parameter) is also used to determine the user and group id of all sub-processes spawned by innd, as well as the owner of all news articles and files. The owner of this directory is set at installation time and specified in the ``Ownerships and file modes'' section, above.
