@subsection What firewall should I use with Cygwin?
@subsection What does "mount failed: Device or resource busy" mean?
We have had good reports about Kerio Personal Firewall, ZoneLabs
Integrity Desktop, and the built-in firewall in Windows XP. Other
well-known products including ZoneAlarm and Norton Internet Security have
caused problems for some users but work fine for others. If you are
having strange connection-related problems, disabling the firewall is a
good troubleshooting step.
@strong{(Please note: This section has not yet been updated for the latest
net release.)}
This usually means that you are trying to mount to a location
already in use by mount. For example, if c: is mounted as '/'
and you try to mount d: there as well, you will get this error
message. First "umount" the old location, then "mount" the new one and
you should have better luck.
If you are trying to umount '/' and are getting this message, you may
need to run @code{regedit.exe} and change the "native" key for the '/'
mount in one of the mount points kept under
HKEY_CURRENT_USER/Software/Red Hat, Inc./CYGWIN.DLL setup/<version>
where <version> is the latest registry version associated with the
Cygwin library.
Cygwin uses sockets to implement many of its functions, such as IPC.
Some overzealous firewalls install themselves deeply into the winsock
stack (with the 'layered service provider' API) and install hooks
throughout. Sadly the mailing list archives are littered with examples
of poorly written firewall-type software that causes things to break.
Note that with many of these products, simply disabling the firewall
does not remove these changes; it must be completely uninstalled.
@subsection How can I share files between Unix and Windows?
During development, we have both Unix boxes running Samba and
NT/Windows 95/98 machines. We often build with cross-compilers
under Unix and copy binaries and source to the Windows system
or just toy with them directly off the Samba-mounted partition.
On dual-boot NT/Windows 9x machines, we usually use the FAT
filesystem so we can also access the files under Windows 9x.
During development, we have both Linix boxes running Samba and Windows
machines. We often build with cross-compilers under Linix and copy
binaries and source to the Windows system or just toy with them
directly off the Samba-mounted partition. On dual-boot NT/Windows 9x
machines, we usually use the FAT filesystem so we can also access the
files under Windows 9x.
@subsection Are mixed-case filenames possible with Cygwin?

Several Unix programs expect to be able to use to filenames

@code{makefile}. WIN32 can't tell the difference between files with
just different case, so the configuration fails.
In releases prior to beta 16, mount had a special mixed case option
which renamed files in such a way as to allow mixed case filenames. We
chose to remove the support when we rewrote the path handling code for
beta 16. The standard Windows apps -- explorer.exe,
cmd.exe/command.com, etc. -- do not distinguish filenames that differed
only in case, resulting in some (very) undesirable behavior.
To help with this problem, starting in @samp{cygwin-1.5.0} it is
possible to have a case sensitive Cygwin managed mount. This is an
experimental feature and should be used with caution. You should only
use it for directories that are initially unpopulated and are due to
be completely managed by cygwin (hence the name). So, the best use
would be to create an empty directory, mount it, and then add files to
it:
Sergey Okhapkin had maintained a mixed-case patch ('coolview') until
about B20.1, but this has not been updated to recent versions of Cygwin.
@example
mkdir /managed-dir
mount -o managed c:/cygwin/managed-dir /managed-dir
cd /managed-dir/
touch makefile
touch Makefile
