Re: Files created with CYGWIN have "NULL SID:(DENY)" windows ACL, inter alia
Hello Andrey - many thanks again.
I have added noacl to the default fstab entry, so it reads:
none /cygdrive cygdrive noacl,binary,posix=0,user 0 0
and that sorts out the permissions problem, thank you.
But, bizarrely, it introduced a new one - the WHICH command no longer
reports non-executable files on the PATH.
Such files are found and executed OK (presumably because Windows logic
is adhered to, where execute permission is not required), but WHICH
doesn't "see" them.
So I had to build a work-around for WHICH (which I use in various
scriptware) since I can also find no way to set the execute bit on a
file ("chmod a+x" doesn't seem to do anything with or without noacl).
Thanks again,
Peter

Re: Files created with CYGWIN have "NULL SID:(DENY)" windows ACL, inter alia
Hello Andrey - many thanks for that. I have now removed /etc/passwd and /etc/group which didn't change anything. I read some of your earlier posts on this and had already tried the noacl route. Unfortunately it has made no difference. I added a second line to my fstab so it read: none /cygdrive cygdrive binary,posix=0,user 0 0 e: /cygdrive/e ntfs noacl,binary,posix=0,user,auto 0 0 with "mount" showing: C:/cygwin/bin on /usr/bin type ntfs (binary,auto) C:/cygwin/lib on /usr/lib type ntfs (binary,auto) C:/cygwin on / type ntfs (binary,auto) E: on /cygdrive/e type ntfs (binary,noacl,posix=0,user) C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto) D: on /cygdrive/d type ntfs (binary,posix=0,user,noumount,auto) N: on /cygdrive/n type smbfs (binary,posix=0,user,noumount,auto) P: on /cygdrive/p type smbfs (binary,posix=0,user,noumount,auto) But when creating files on an E: I still get DENY for "NULL SID" and other accounts.

After Windows 10 upgrade, SH fails "fork: can't reserve memory for parent stack"
After Windows 10 upgraded itself from 10.0 (Build 10240) to 1511
(Build 10586) shell scripts fail with fork errors.
This can be demonstrated from a Cygwin64 Terminal window by running a
trivial pair of commands. Create these two files in a folder:
1. win1511.pl containing the three lines:
my $subShell = "sh win1511.sh arg1 arg2";
print "Running: $subShell\n";
system("$subShell")
2. win1511.sh containing the four lines:
#!/bin/bash
echo win1511.sh starts
sh -c "echo FROM SUBSHELL"# This fails under Windows (10) 1511
echo win1511 all done
Then change to the folder and run: perl win1511.pl
On a Windows 10 (10240) this reports, as expected:
Running: sh win1511.sh arg1 arg2
win1511.sh starts
FROM SUBSHELL
win1511 all done
But on the "upgraded" Windows, it reports something like:
Running: sh win1511.sh arg1 arg2
win1511.sh starts

64-bit TAR fails with "Cannot connect to e: resolve failed"
Please ignore/delete this - I realise this has nothing to do with the change from 32 to 64 bit.

Re: LS and TAR don't see any file permissions (
Have found my solution ... robocopy. Using it's /secfix option copied files are owned by the copying user. eg: robocopy x:\tmp .\tmp /e /secfix Note: you need a not-too-old version of Robocopy for the /secfix support (I was using v 1.96).

Many thanks indeed Mark - GMANE was prefect - so much easier than mucking around with "raw" mail messages.

I know it's not a Cygwin issue, but can you suggest an easy way to get miserable Windows to copy files to a new machine in a way that does give the current user ownership (ideally using some normal-ish Windows commands)? I tried using Windows Explorer copies and Winzip-ed .zip archives - both end up with the problem below. I have done this before when transferring PC's, but then I would have been the same user on both, Here I am also moving to a different domain\username on the new PC. -- Peter -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

Many thanks - I'm using gmail. Any idea how I would do that with it? Also, is there no way then to join into a thread unless one has access to a mail from the mailing list?

How do I add a follow-on post to a thread in this mailing list?
Sorry to be really dim, but I can't see how to do this. I am trying to add a follow-on message to http://www.cygwin.com/ml/cygwin/2011-03/msg00167.html (which I initiated). But, I posted my original message before I had subscribed to the list under my posting email address (gmail.com). I had subscribed to the list under my work email address (which I cannot post from). So, I forwarded Eric's useful reply from there to my gmail.com account. I then did reply to that, but set the "TO" address as "cygwin at cygwin dot com". But that reply has not appeared (though I got no delivery error message). What incantation do I need to continue my original thread, please? -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
LS and TAR don't see any file permissions ("ls -l" shows "----------+ ...")
When running "ls -l" the permissions field shows as "--+". Oddly, "ls -l" shows the correct permissions if the pathname uses the windows drive letter syntax. eg: $ pwd /cygdrive/c $ ls -l tmp/plb.txt --+ 1 ga2binn Domain Users 5527 Mar 3 13:54 tmp/plb.txt $ ls -l c:/tmp/plb.txt -rw-r--r-- 1 ga2binn Domain Users 5527 Mar 3 13:54 c:/tmp/plb.txt Similarly, TAR images have no permissions on the files contained. eg: $ pwd /cygdrive/c/tmp $ tar cf - plb.txt | tar vtf - -- ga2binn/Domain Users 5527 2011-03-03 13:54 plb.txt Even more oddly, this behaviour (both LS and TAR) occurs on a new PC that I am moving to. I have the same version of Cygwin on an older PC which does not have the problem. I have diffed the "cygcheck -s -v -r" output from both PC's and can see nothing that would explain the broken behaviour on the new PC. Both PC's are running the same version of XP SP3. I have also reinstalled Cygwin with the latest version (its cygcheck attached).
