Thanks, but..

With 20060202, that testcase now works, but if you read all the way to
the end, then rewind, you only get . and .. thereafter.

$ cat rewdir.c
#include 
#include 
#include 
#include 

void readentries(DIR *dh, int limit) {
  struct dirent *de;
  int count;

  for (count = 0; count < limit; ++count) {
errno = 0;
if ((de = readdir(dh)) == NULL) {
  if (errno != 0) printf ("read error: %s\n", strerror (errno));
  break;
}
printf ("got: %s\n", de->d_name);
  }
}

int main(int argc, char **argv)
{
  DIR *dh;
  int i;

  if (argc != 2) return 1;

  if ( (dh = opendir (argv[1])) == NULL ) {
fprintf (stderr, "couldn't open '%s': %s\n", argv[1], strerror (errno));
return 1;
  }

  for (i = 0; i < 3; ++i) {
readentries (dh, );

printf ("rewinding.\n");
errno = 0;
rewinddir (dh);
if (errno != 0) printf ("unexpected errno: %d\n", errno);
  }

  return 0;
}

$ rm -rf foo; mkdir foo; touch foo/{bar,baz,quux,quuux,qx}

$ gcc -Wall rewdir.c -o rewdir && ./rewdir foo
got: .

Do the hints in the Cygwin FAQ about Unicode help?

Perhaps this will help, from the version announcement:

"I've just updated the version of shutdown to 1.7-1.

This version adds the -x/--exitex option, which allows to use the
ExitWindowsEx function on Windows NT.  This is important if shutdown is
supposed to poweroff on Windows 2000, since the InitiateSystemShutdown
implementation on Windows 2000 unfortunately misses to do this."

Regards.

shutdown

Hello world!,
I need to shutdown my win 2000 O.S. at a specified time or "now".
I'd like to use the command shutdown --force now but the system answer is
that I don't have the necessary priviledge. How can I do? Have I to activate
some service with cygrunsrv.exe for exemple? I'm working in an Antarctic
base without internet connection, so I cannot access the web information.
thak you for your help!!

Re: Problems with sshd under Windows XP

[Fabian Pauly]

My problems are solved now. So here a short report what my problem was:

I encountered two kind of problems:

1) First somewhere in the cygwin-Archive it was mentioned, that one can
change the user name simply by editing /etc/passwd. As my windows name was
"first name"\ "lastname" I changed it to my usual login name, let's say
"pauly". However Windows than does not know about a password for pauly when
a login to the Windows computer is taking place because user pauly does not
exist. A real change of a user name in WindowsXP Home does not seem easy as
a change of the user name does not change the user's directory name (in
Windows XP Home). So I accepted "first name"\ "lastname" as my login name.
After a new installation of cygwin I could than install sshd even with
"privilege separation yes". (/etc/passwd should have the same entries as
mkpasswd -l).

2) The second problem was purely ssh-related. I have linux and Windows on my
machine. For linux I have a sshd running for a long time. And the host keys
newly generated during the installation of sshd under Windows was of course
different to the linux host keys. So the client recognized that the host
keys were different and stopped the login progess. This problem can simply
be solved by copying the linux hostkeys to windows.

Cygwin is really fantastic! The xserver and the running sshd I find really
impressive! Great job! Fabian.

P.S.: Of course I also read the cygwin-doc. However I find the links
actually contain better understandable instructions than the
'/usr/share/doc/Cygwin/openssh.README' file, which adresses newly included
features and seems somewhat inconsistent -- at least without clear, simple
instructions. Anyway it works now.

sed

[Rokas Masiulis]

Hi,

i can't force to work sed in true binary mode:

this is test case:

$ echo -en '\r\n' | sed -e '' | od -t x1
000 0a
001

but expected result is:
$ echo -en '\r\n' | od -t x1
000 0d 0a
002


on linux this thing works: 
[EMAIL PROTECTED] $ echo -en '\r\n' | sed -e '' | od -t x1
000 0d 0a
002


some info:

$ mount
C:\cygwin\bin on /usr/bin type system (binmode)
C:\cygwin\lib on /usr/lib type system (binmode)
C:\cygwin on / type system (binmode)
c: on /cygdrive/c type system (binmode,noumount)
e: on /cygdrive/e type system (binmode,noumount)
f: on /cygdrive/f type system (binmode,noumount)
g: on /cygdrive/g type system (binmode,noumount)

$ echo "$CYGWIN"x
x

I meant in the case of a trailing dot.  On Linux, if directory FOO doesn't
exist, "rmdir FOO/." returns ENOENT.

The fix is pretty much the same as what you did for mkdir, except that
EEXIST is replaced by EINVAL...
