Cygwin is a bit different from other Unix-like systems (see
<http://cygwin.com/acronyms/#CYNUX>.  A lot of the time, to find out how
some application works on Cygwin, you should look at the Cygwin-specific
README file for the package, which is usually present as
/usr/share/doc/Cygwin/<packagename>.README (or, for older packages,
/usr/doc/Cygwin/<packagename>.README).  This is especially true for
daemon packages, like inetd, openssh, sysvinit, etc.

Not by default.  See the sysvinit package (and the Cygwin-specific
README!).

Try the Linux documentation project (<http://tdlp.org/>).  However, as
said above, Cygwin is not Unix (or Linux), so this mostly won't help.
Again, I'd refer you to the sysvinit package.

If you did a full install, you most likely have installed openssh.  You
most likely *aren't* running sshd.  See the Cygwin-specific README for the
openssh package.

No, no, no.  You run "cygcheck -f /usr/sbin/<programname>" (e.g.,
"cygcheck -f /usr/sbin/in.ftpd.exe"), and then look at the Cygwin-specific
README for the package which that command returns.  If there is no
Cygwin-specific README, or it doesn't contain the necessary information,
only then do you go to the regular package docs.

On Unix, /usr is usually mounted off a shared network disk, so /sbin
contained all the daemons needed to boot the machine and bring it to
operation even if the network is down, and /usr/sbin contained all the
rest.  On Cygwin, there is no /sbin (historically).  Yet another
demonstration that <http://cygwin.com/acronyms/#CYNUX>.
