Cygwin 1.7 Windows 7/2008 Public key intermittent problem
Hi, I have about 8 machines experiencing problems while trying to use passwordless public key authentication, via passwd -R. Happening on W7, w2k8, x86 x64 sshd running on all as a domain user, with the correct local security policy changes made, and /var/empty owner by sshd user etc. pub key auth always works for the user sshd is been run as, but not any other user - connection closed by... error - windows event log does show sshd pid xxx fatal initgroups permission denied error If I reboot any of the above, generally passwordless pub key auth doesn't work - if I then rdp to windows machine, login as another user, log out - I can then ssh using keys to that machine as the user I RDP'd as - until it gets rebooted again. And then - after several more reboots - without any changes been made on the machines - I can use keys to login to the machine as any user successfully - until it gets rebooted and reverts to the usual problem I have tried installing cyglsa - but after installing and rebooting - I don't notice any difference - although I'm unsure if there is something else needed for cyglsa to function or is adding the users to the passwd/groups sufficient? Thanks for any suggestions - the fact that it intermittently works is baffling me Cheers Shane -- 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
Re: 1.7 Public Key Authentication problem
Thanks for the info - I wasn't aware of passwd -R - just tried it and it works which is a good relief. It's a dev lab - anyone with access to the keys is allowed full rights to the machines - so security not a major concern. BTW - I had installed cyglsa-config and rebooted and gave the users the Act as part of OS right - but it doesn't work for me. I must be missing something .

The Cygwin User Guide goes into great detail about the methods of changing user context, in this chapter: http://cygwin.com/cygwin-ug-net/ntsec.html The gist of that chapter is this: If you want to be able to login via ssh as a user that is not running the sshd daemon, you have basically two options: (1) Provide a valid Windows password to the sshd daemon, either interactively (which you obviously don't want to do, since you're attempting public key auth), or stored statically in the registry via 'passwd -R'. (2) Use the LSA authentication package. Bear in mind that if you use this option to avoid giving sshd your password entirely, I believe that certain privileges are withheld from the logged in user.

Checking XCOPY Exit Value in Cygwin Bash
Hi all,
I am writing a automated build script for my project that will be run
under cygwin. I will copy my updated source files to the build directory and if
there are updated files, the executables will be built. To copy the source
files, I had to use XCOPY since the directory structure should be preserved in
the destination directory also. To copy only the updated files, I used the /D
switch for XCOPY. Now since I want to execute the source compile only if files
in the build directory have been updated, I have to use the exit codes of XCOPY
inside the script. I tried checking the value of $! after executing XCOPY but
it didnt work. I couldn't find a solution in the internet too. Currently I am
piping the standard output to a file and checking if the number of files copied
is 0 or not. But I think this is not an elegant solution. This is what I am
doing now.
[script]
copied=false
# Helper Function
copy_files()
{
echo copying *.$1 files in $2 to $3\\$2
xcopy /DSYI $2\\*.$1 $3\\$2 | tee copy.log
while read amount ; do
if [ ${amount::1} != 0 ]; then
copied=true;
fi
done copy.log
}
cd ../source
copy_files h. ..\\build
copy_files c. ..\\build
copy_files cpp . ..\\build
rm -f copy.log
! $copied echo Files up-to-date. Skipping build exit 0
cd ../build
# Start the Build Process
[/script]
Can you please provide me a way of checking the XCOPY exit code: reference
[http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/xcopy.mspx?mfr=true]
within Bash?
Thank you for your time.

Igor Peshansky wrote: Nope, you didn't have to. Something like (cd $2/.. find $2 -name *.$1 | tar cfT - -) | tar xfC - $3 would do the job of XCOPY /S using POSIX means. If you go POSIX, you can use the --keep-newer-files tar option. Of course it didn't. Please read a good bash tutorial, or the Special Parameters section of the bash manpage. Hi Igor and Mark, Thank you very much for the quick reply. I was initially using tar -cf - `find $source_dir -name *.$file_ext -print` | ( cd $dest_dir tar xBf - ) but it had a problem with path names with spaces. Obviously being not that good in bash scripting, I couldn't get over that issue. So that was why I decided to use the XCOPY command. I will use your method and see. Thanks again. I made a silly mistake in my former email. I was actually checking $? (not $!) for the exit code, but it didn't work. But I saw in a later reply from Mark that it worked for him. I will check it again.

Re: Checking XCOPY Exit Value in Cygwin Bash
David Christensen wrote: There are standard software development tools that solve the problems you are facing -- CVS and Make: http://ximbiot.com/cvs/wiki/index.php?title=Main_Page http://ximbiot.com/cvs/wiki/index.php?title=Main_Page Both are included in Cygwin. In the long run, you'd be better off investing in a basic to intermediate understanding of both rather than hacking together custom scripts to implement a subset of their functionality. To David, Thank you for the tip. Actually I am using Visual Source Safe as the Source Management tool. I was considering the use of CVS, but decided against at the last moment because most of the fellow developers including me, had been using VSS for a considerable amount of time, and felt that the migration from a VSS to CVS would take a some time. Similarly for Make. We are primarily a group of developers who are conversent with MS Windows than the Unix environment. Cygwin basically gives us the power of bash scripting and the ease of Windows at the same time. :) What I am trying to do is, checkout the source to the build directory and if there are any local changes in my working directory copy them to the build directory, build and do a test run from there. This is so that I can test my code before I do the actual check in. To Igor, Your method worked perfectly for paths with spaces too. :) Now if only I had a way of detecting if files were updated or not. To Mark I tried it again. Unfortunately echo $? gives 0 for both the cases of, number of files copied = 0 and, greater than 0. The link I posted from MSDN http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/xcopy.mspx?mfr=true says that XCOPY returns 1 when there were no files to be copied. So I guess I am back to square one. :( Thanks and best regards Shane GET FREE 5GB ONLINE STORAGE - Safely store your documents, photos and music online!

Re: Checking XCOPY Exit Value in Cygwin Bash
Igor Peshansky wrote:
As David said, cvs has an easy way of doing this (using cvs diff and
patch), which will also deal with local and checked in changes to the
same file (while your method won't).
Point taken. I will certainly look into it.
Did you happen to notice the mention of the --keep-newer-files tar
option in my original reply to you? Just add that to the last tar, and
you will only copy the files that were changed in your copy (presumably by
you) after the checked in version.
Yeah I saw that reply and I had tried it. There were two problems.
1. New files will not be added to the build directory. It will say
something like
tar: ./Test/res/Test.manifest: Warning: Cannot stat: No such
file or directory
tar: Current `./Test/res/Test.manifest' is newer
and the required manifest file is not copied into the build
folder. So for the initial copy I have to
use it without the --keep-newer-files, and for the subsequent
copies I will have to use the --keep-newer-files.
2. This is the real problem. That is getting an indication whether
none of the files were updated or not. I want to proceed
with the rest of the building script only if more than one files have
been copied. I do not know how to get that using the tar
command. I tried echoing the $? value but it gives 0 all the time. The
source compiler can
detect if the sources were updated or not, on it's own, but
there are a lot of projects in one Visual Studio
Solution (about 60), that I can't wait until all those projects
have been parsed.
I am using
while read amount ; do
if [ ${amount::1} != 0 ]; then
copied=true;
fi
done copy.log
for that purpose.
MSDN apparently lies. XCOPY for me returns non-zero on error, and 0 on
normal execution (no matter how many files were copied).
If that is the case, then there is no point in trying to check for the
xcopy return value.
As a short term solution I will stick with my original XCOPY solution.
But I will try to find out
what CVS, Make and the other tools have to offer. If there is a way of
getting if files have been replaced using the
tar command, I will try to implement that into my solution.
Although I am fairly competent at programming in C/C++, this is my first
attempt in writing a serious bash script,
and I must admit that I am both impressed and overwhelmed by it's power. :)
Thank you all for the help offered so far.

Re: Checking XCOPY Exit Value in Cygwin Bash
What's wrong with cp -a or cp -r? It only copied files that were directly under the source directory. It didn't traverse the directories inside source recursively. I did some searching and, I came up with a similar thread. Finally the tar method was recommended in it too.

Keyboard and Mouse Input delay/pausing using 6.8.99.901
G'day All, I just updated to 6.8.99.901 from 6.8.2.0 for Xorg under Cygwin. Logging in via XDMCP to a remote hosts is causing me some issues now. I connect okay, but as soon as I enter some text into a Konsole or the like, a variable keyboard delay of 0.5-1.0 seconds seems to start. It also seems to be affecting mouse inputs as well. You click on a button and it ma react 0.5-1.0 seconds later. If I start the session and interact only with the mouse all is fine. As soon as I enter any text anywhere, this random delay/pausing starts to happen. It is strange that at the initial XDMCP login window, entering text does not seem to have any problems. The problem only starts after getting to the desktop stage. I get the effect with either KDE or Gnome desktops. It also effects Fedora5 and Ubuntu 6.06 systems. If I run version 6.8.2.0 the problem is resolved. If I use another X server like X-Win32 the problem is also resolved. I'd rather use the Cygwin X server because it seems much more compliant than other X servers for X11 and OpenGL work. Is anyone else getting this problem? Have Fun !!

Python shell ignores keys
Greetings, I'm trying to use the Python shell from within Cygwin. The complication is that I need to use the Windows version of Python not the Cygwin version, ultimately through ssh, but atleast from a cygwin bash prompt for now. The problem is that the Windows Python shell ignores or doesn't recv important keys like ctrl- z or ctrl-c and the up/down cursor keys move the cursor not the command line history. Otherwise everything seems to work fine (the scripts themselves run without an issue), atleast for what I need. I do quite a lot of python programming, its not really feasible (or a good idea) to maintain a second cygwin python installation. I realize these guys are chalk and cheese, but is it possible to fix this ?

Installation Freezing 90%

Here are the basics of what is shown on the screen. Installing. xorg-x11-f100-6.8.1.0-3 /etc/postinstall.xorg-x11-f100.sh And again this is when it reaches 90%. I even once tried closing as much down as I could on the computer i.e. little running processes and then trying installation. The same happened. I let installation take its path to see what would happen but then stopped it when it reached using about 369,340K Memory Usage. If needs be I could host a screen dump I took of the installation at this 90% stage host it and send you a link for you to view (It shows the installation, giving details of the above e.g. the file its installing and where to and also shows the percentage bars etc. It also shows Windows Task Manager giving details about the process.

correctly runs the script. In general I'm finding that all network
related calls (creating new sockets and similar) are failing.
I also note (and think that it's related) that uname -n returns the
correct mixed case hostname when run from the shell prompt but returns
an incorrect (all upper case) string when run from the
cgi-bin/test-cgi shell script. This eliminates Perl from the equation.
I think this is the same problem as posted to this mailing list by:
Richard Morse [EMAIL PROTECTED]
Problems with Amanda and Cygwin 1.5.10

and
David A. Rogers [EMAIL PROTECTED]
Socket problem w/ apache perl cgi
30/07/2004
I did not notice any follow up posts to these queries (my spam filter
was rejecting some Cygwin mailing list posts).
I think this may be the same problem that I reported here:
http://www.cygwin.com/ml/cygwin/2004-08/msg00452.html
Rolling back to the previous cygwin version is the only way I have
been able to get connections via apache to remote databases.
Creating sockets via apache failed wheres from perl command line it
worked.

prob with 1.5.10-3 prevents MySQL connect. 1.5.9-1 is OK.
Hello,
With self- built Apache, MySQL, OpenSLL and Mod_SSL I have found an
obscure bug in cygwin 1.5.10-3 that is not present in 1.5.9-1.
I am installing clean onto XP Pro (without the default inclusion of
Apache). I am then building OpenSSL, mod_SSL, and Apache from their
sources. I am installing the latest perl DBI and DBD::mysql module.
Everything is building and installing with successful make test
runs using the script below.
With Cygwin Core 1.5.9-1 I can successfully connect to a remote mysql
server from a perl script in both the shell and also from a perl
script called from a web page. Great!
With Cygwin Core 1.5.10-3 I can *NOT* connect to the remote mysql
server from a web page called script. Apache generates the error
DBI-connect(database=test;host=my hostname) failed: Can't create
TCP/IP socket (1)
The same script called from a command line perl CAN conenct to the db
without problem (after all the make test for DBD::mysql passed
100%)
I found one other reference to a similar error from an older version
without any resolution
http://www.cygwin.com/ml/cygwin/2001-03/msg01748.html
To be clear...
everything compiles, tests, and installs without error using both
Cygwin Core 1.5.9-1 and Cygwin Core 1.5.10-3 however with 1.5.10-3 I
can not access any remote mysql databases from a web-called perl
script where a command line called script is fine...go figure.
There are no errors in building this kit with either version of the
Cygwin dll - just that the old version workls for me when the current
version does not.
If anyone wants me to test something to resolve why this happens I'm
happy to help...but otherwise I hope this helps the developers. Let
me know If I can help further then with this report!
Details on the scripts follow. If for nothing else this report will
be archived to help someone else with the install g
Cheers,
Shane
The perl test case script is:
###
#!/usr/local/bin/perl
use DBI;
$database = test;
$host = host.somewhere.com;
$username = user;
$password = pass;
$dbh = DBI-connect(DBI:mysql:$database:$host, $username,
$password);
if (not $dbh) {
print Content-type: text/html \n\n you cannot connect to the
database;
}
else { print Content-type: text/html \n\n successful connect; }
exit;

The script I use to clean build apache with mod_ssl, mod_auth_dbm and
mod_rewrite is...

So to be clear the two systems (one working and one not) differ in both cygwin and perl versions (nothing else). Oddly both systems can connect to a remote DB from perl - just not when a browser calls the script from apache. Lastly - it makes no difference which version of cygwin apache was compiled with. If we take a working system and then just upgrade perl and cygwin without rebuilding the error occurs. Likewise a non- working system that downgrades cygwin and perl suddenly works ok.

RE: Problem with keymap under cygwin-xfree
Device Manager identifies it as a Standard 101/102-Key. The problem with the workaround is that pressing the '1' key reports as keycode 43 and generates an h. Pressing an 'h' also reports as keycode 43 and generates an h. Hence, if I remap keycode 43, I now have a 1, but no h. This is so freakin mystifying. Why would two keys report the same keycode when pressed?? -Original Message- From: Thomas Chadwick [mailto:j_tetazoo;hotmail.com] Sent: Thursday, November 07, 2002 12:22 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RE: Problem with keymap under cygwin-xfree Looking at XWin.log, I can tell you're using an XF86Config file. However, your settings seem to match mine, which is good, I think, since I don't use an XF86Config file at all (resulting in defaults). Since xev is telling us that the X server is at least getting the keystrokes, a work-around would be to systematically figure out the keycodes using xev, and then add them to your .Xmodmap file. For instance, if xev reports that pressing the 1 key gives you keycode 200, then put keycode 200 = 1 exclam in .Xmodmap. As for the root cause? I'm at a loss to explain it. However, I'm not exactly an expert on the subject, so hopefully someone else on the list may be able to figure it out. One other thought: Maybe your keyboard isn't a standard 101/102-key keyboard?

I have attached a small piece of code (and sample file) which demonstrates the problem. Basically if the offset parameter is passed as a variable to mmap then the call fails with an ENOMEM error. But if you pass 0 as the parameter and then access the return address from mmap + offset - it is fine. My question: is mmap handling the offset parameter correctly? Usage for the program: ./a.exe offset file eg: ./a.exe 11200 index.idx To see the address + offset work, comment out the first mmap call and return statement and uncomment the lines below each one. Any help appreciated. Your application tries to mmap over EOF.
