chmod and ntsec

chmod and ntsec

[Noel L Yap]

I'm running CygWin on Win2k with CYGWIN="binmode ntea ntsec tty".  I'm not sure
what version of CygWin I'm running.

When I try to chmod something, I get a permission denied error.  But I'm able to
change the permissions through Window's GUI.  What am I doing wrong?  Does chmod
not support NT security, yet (is it even possible for it to)?  Do I need to
upgrade?

Thanks much,
Noel

You'll find allot of good information in the user documentation.  It describes
what you need to do to make ntsec work for you on NTFS partitions.  Check it
out and see if that helps you solve your problems.

Subject: chmod and ntsec

If you can't be bothered to read the 9 page FAQ on ntsec, try this:

bash> cp -p /etc/passwd /etc/passwd0 && mkpasswd -l -d >/etc/passwd
bash> cp -p /etc/group  /etc/group0  && mkgroup  -l -d >/etc/group

The "-l" switch examines your NT musrmgr.exe database.
The "-d" switch must examine the user database on your domain.

I wasted a load of time trying to get ntsec working, too, so now I just use "ntea" in the CYGWIN variable. Apparently this is not a
good idea for FAT disks, but all mine are NTFS so I don't care.

Just remember that all diskettes are FAT and that you can't create a
NTFS diskette.  So, if you use your Cygwin utilities to access the
diskette then you will get an attributes file on the diskette.

So is the definitive, expert answer to use "ntsec" or "ntsec ntea"?

The ntsec flag overrides the ntea flag IIRC.  There is no reason to use
the ntea flag if you use the ntsec flag.  The ntea flag, IMO, should be
removed in the next release as it can cause more consequence than good.

I guess the big question here is whether anyone finds the use of ntea useful
for FAT partitions.  This is the one advantage that ntea has over ntsec.  If
the answer here is that ntea is considered useful for FAT despite the ugly,
quickly growing file it produces, then I'd say keep it.  Just my $.02.

Where: Either in the global environment settings

	"Start" -> "Settings" -> "Control Panel" -> "System" -> ...

or in the startup batch file

	set CYGWIN=binmode notty ntsec

You will use ntea on FAT and ntsec on NTFS then. It's a personal
choice. ntea is fake, ntsec needs some understanding of NT security.

In the online user's guide:

I did not miss this: But I dont know WHERE and HOW to set these environment 
variables. I work with NTFS-Partitions and with FAT-Partintions. Is it 
better to select >>ntea<< (how big will the mentioned additional files be 
and will they be built once or will they become bigger every time I use 
some features?) or is it better to to select >>ntsec<< (which will not work 
with the FAT-partitions). What happens, when I use both?
Also, there is a file >>ntsec.sgml<< mentioned. Where can I find this file?

chmod and ntsec

[Heimo Ponnath]

Hello,

i am new in this list and in CygWin. I work with Windows NT 4.0 and the 
newsest version of CygWin (1.1.18) and - yes, I searched the list-archives 
and read the FAQs. But there are still some facts left which I dont understand.

One of the problems is, that chmod does not work. In the list and in the 
FAQ there is an Environment variable mentioned, which should be set: ntsec.
Could you please tell me, where and how and to which value I can/should set 
this ntsec?

I have some more questions - but I hope, you can help me with this first one.

Heimo Ponnath
