Using Windows security in Cygwin. This section discusses how the Windows security model is utilized in Cygwin to implement POSIX-like permissions, as well as how the Windows authentication model is used to allow cygwin applications to switch users in a POSIX-like fashion.

Using Windows security in Cygwin

The setting of POSIX-like file and directory permissions is controlled by the mount option (no)acl which is set to acl by default. POSIX concepts and in particular the POSIX security model are not discussed here, but assumed to be understood by the reader. If you don't know the POSIX security model, search the web for beginner documentation. In the Windows security model, almost any "object" is securable. "Objects" are files, processes, threads, semaphores, etc. Every object has a data structure attached, called a "security descriptor" (SD). Flags which control several aspects of this SD. Every ACE contains a so-called "Security IDentifier" (SID) and other stuff which is explained a bit later.

SID of a machine "foo": It's a bit different in domains. Note. Cygwin Part 1. Useful Configuration of Cygwin, Part 1: Install, rxvt, and BASH Installation To install cygwin first download and run the setup.

Cygwin installation experience and notes

The programmers I work with would find it highly amusing if I offered advice on anything having to do with setting up a computer. This page is more for me to keep track of what I've done rather than to offer a brilliant template for others, but you're welcome to see what I've done. Installation preliminaries Get the "setup.exe" tool from What I installed I wanted TeX and program development environments, and like to work in X-windows. Path work Do a search to identify Windows programs that use cygwin1.dll and have their own versions of this dll (e.g. ds9, fv, etc.). Starting the X-Windows manager To get a single -- one and only one -- X-Window terminal, type startx. (the display must still be set properly and the script must be executable, of course).
