ssh login to PC stopped working

[luke . kendall]

This afternoon, while trying to diagnose why I couldn't slogin to a new
machine with Cygwin installed, I slogin-ed to my own PC (logged in
successfully) and looked at some file permissions.  Then logged out.

A few minutes later I tried to slogin again, and this time it failed.
(I am confident no one else touched the machine in the meantime, since
I was nearby and could see it the whole time.)

Since then, I sorted out the problems on the new machine (/var/empty
wasn't owned by system, and group not writeable, and similarly for
/etc/ssh*: none of which is detected by ssh-host-config), and so was
able to start sshd and slogin to the new machine.

But I can't work out what's wrong on my own PC (doyle) now!  It appears
to accept the password, then simply close the connection.

And this problem developed minutes after it had all been working.  Is
it failing because I don't have write permission on /var/log/sshd.log?
I have Administrator rights.

Any suggestions about how I could diagnose what's going wrong?

Some possibly useful info is:

Running cmd programs in cygwin / rxvt

[overbored]

There are some cmd shell programs that don't run well in rxvt. Most 
noticeably, they don't always immediately write out their output. They 
seem to work fine in the default cmd window though (doesn't matter if 
it's in cmd or in bash). Does anybody know what the problem is here, and 
how to fix it? Thanks in advance.

Login behaviour oddities: won't run .profile

[luke . kendall]

I looked into a problem reported today, that ~/.profile is not executed
if you use Cygwin to create your home directory, instead of using
Windows Explorer to create the directory.

The user who reported it and I played around for a while, with getfacl
and setfacl to try to find the difference and fix them.  While setfacl
doesn't seem to allow you to do everything you need (specifically, you
can't use it to delete the default group ACL for ~ since you have to
specify a group, but there is no group for the default group), ACLs may
not be the full explanation anyway.

We managed to set the two directories to appear to have identical ACLs
according to the Advanced security tab in the Windows Explorer
properties - but that still didn't help!

Cygwin will only run ~/.profile if "~" was created via Win Explorer.
(This seems to be reasonably new behaviour - we've got a lot of users
who would have been affected every day, if this had been true for a
long time.)

My colleague said that he had to run an strace (presumably on bash), to
find out why .profile was being run.  It appears to stat ~/.profile,
look at the ACL, and then close .profile without reading and executing
commands from it (in the case where ~ was created by a Cygwin mkdir).

We explicitly mount, e.g., D:/home on /home in textmode, if that's any
help.

I've confirmed this problem on a fresh install.  I'm continuing to look
into it.  It doesn't appear to be a problem for older Cygwins.

CYGWIN_NT-5.1 DOYLE 1.5.10(0.116/4/2) 2004-05-25 22:07 i686 unknown unknown Cygwin

(That version above seems insensitive to who creates ~.  Whereas the one
below is sensitive.)

CYGWIN_NT-5.1 STOUT 1.5.10(0.116/4/2) 2004-05-25 22:07 i686 unknown unknown Cygwin

Hmm.  They look the same to me (perhaps because I update my Cygwin
quite regularly).

Anyway, as I said, I'm just starting to look into this.  Feel free to
suggest other tests I should try or things I should look into.

Regards,

luke

Cygwin doesn't support ipv6 and therefore Cygwin's OpenSSH doesn't suport
it, too.

get/setfacl are not designed to manipulate the ACLs in a WIndows way,
but in a Unixy way.  Keep in mind that you always have a primary
group and always primary group permission bits in the POSIX permissions.
You can't delete them, just set them to --- if you like.  To get rid of
the primary group ACE entirely, either use NT tools (cacls) or change
the primary group for the file first.

Sorry but this is bogus.  There's no difference whether a directory is
created using Cygwin or Windows.

bash gets its idea of where the home directory is from the setting of
$HOME.  When starting up `bash --login' locally, then the Cygwin DLL
constructs $HOME using the following rule:

- If $HOME is present in the environment, convert it to a POSIX path
  and use it.
- Otherwise, if the user has an /etc/passwd entry and this entry contains
  a non-empty pw_dir field, use this as $HOME.
- Otherwise, if $HOMEDRIVE and $HOMEPATH are set in the Windows environment
  (they usually are), use them to create a POSIXy $HOME from them.
- Otherwise use "/" as $HOME.

Does that help?

No.  I don't see any change in Cygwin between 1.5.10 and 1.5.11 which
could result in a new behaviour on sockets.  The strace is useless.

What you're seeing is caused by the output of the program going through
a tty (or pty as the case may be.)  When you run it from a straight
cmd.exe it's not using tty code (unless you have CYGWIN=tty set.)  From
my meagre knowledge of the subject it has to do with the program not
explicitly flushing stdout (or not knowing that it needs to as this is
usually not required under windows.)

Cygwin-specific Libtool patches (Was Re: Is cygffi.dll needed for SableVM JVM?)

[Dalibor Topic]

Gerrit P. Haase wrote:
It is as is for backward compatibility, new created DLLs don't need
all the stuff with __declspec(import/export), however, some libs still
use it and if you link against one which uses import/export

still some problems with exporting data, so it may also be needed to
use import/export definitions with DLLs containing data, and then it
would break too.  As long as you have libraries which don't use
import/export definitions and since all code is PIC on Windows anyway,
you may safely use pass_all.
I was wondering whether you know if there are pending patches from 
Cygwin developers for GNU Libtool, as they are preparing Libtool 2.0, so 
it would be nice to have those included, if possible :) The Libtool 
upstream is very cooperative and responsive to patches in my experience.

PostgreSQL on Win98: initdb failed

[Christian Rank]

Hello,

I'm trying to run the Cygwin version of PostgreSQL on Windows 98 SE.
During initdb, creation of the initial database cluster is aborted with
the message
creating template1 database in /var/pgsql/data/base/1...
shmat(id=1179648) failed: invalid argument

The sequence of commands leading to this is as follows:

  mkdir /var/pgsql
  export CYGWIN=server
  /usr/bin/cygserver-config -n
  /usr/sbin/cygserver -E &
  mkdir /var/pgsql/data
  initdb -D /var/pgsql/data -E LATIN1

Software versions used:
  cygwin 1.5.11-1
  PostgreSQL 7.4.5-1
  Windows 98 Second Edition 4.10. A

The same setup runs on Windows 2000 without problems. According to the
cygserver docs, it should run on Win98, too.

Does anybody know what's going wrong here?

Thanks in advance,
Christian

Rebuilding GDB

[Adrian Cox]

I'm trying to build a Cygwin hosted GDB for debugging ARM and PowerPC
boards.  After running into a lot of problems, I tried to rebuild the
native GDB that Cygwin installed for me, and that didn't work either.

I'm up to date with Cygwin setup, and running on Win2k SP4. Below is the
end of the build where everything goes wrong:

Umm, sure there is.  Windows Explorer will inherit the permissions of the
parent directory by default, whereas Cygwin will always create a new set
of ACLs (or, at least, I haven't found a way to make Cygwin directories
inherit the parent's ACLs).  I don't know how that can make a difference,
but there it is.

@Luke: when you say "use Cygwin to create the home directory", do you mean
"let /etc/profile create it for you", or "use Cygwin's mkdir"?  If the
latter, then Corinna's right, and it shouldn't make any difference (even
if the inheritance properties differ).  If the former, then beware that
one of the /etc/skel files copied to $HOME by /etc/profile is
".bash_profile", which bash will use in preference to ".profile".  If the
home directory already exists by the time /etc/profile is first run for a
user, the /etc/skel files won't be copied, which I think is what's
happening in your case.

One solution is to remove /etc/skel/.bash_profile after the installs
(maybe even in your own site-specific postinstall script).  I don't know
if the base-files postinstall script will re-create that file, though --
if it does, it needs to be fixed.

What you're seeing is caused by the output of the program going 
through a tty (or pty as the case may be.) When you run it from a 
straight cmd.exe it's not using tty code (unless you have CYGWIN=tty 
set.) From my meagre knowledge of the subject it has to do with the 
program not explicitly flushing stdout (or not knowing that it needs 
to as this is usually not required under windows.)
Is there a CYGWIN setting to tell rxvt not to use ptys?

The base-files postinstall script will attempt to recreate its files
if they don't exist, it can't differentiate between deleted and clean install
(do any?).

If you want to use a ~/.profile instead change /etc/skel/.bash_profile to
be something along the lines of

source ~/.profile

Base-files *will not* (now) overwrite a user modified file.

Would this be sufficient?  I don't know how to improve this... make a note
during preremove of any of the manifest files missing and don't create
them upon installation?  Possible I suppose...

This is a packaging bug in the "sed" package.  It's been apparently
recompiled using libintl3, but the "requires:" line in setup.hint still
says libintl2.

Re: Updated: cvs-1.11.17-1

Dear Charles Wilson,
I'm a cygwin user and I have problems using CVS. I'm trying to use the

FWIW, I tried it ten times without error.  I have it running in a loop

That's more or less correct.  The larger problem is that ptys are
actually pipes under the hood and some native programs don't deal well
with having pipes for their stdin and stdout.  They either don't flush
their output correctly or they refuse to output anything at all.

I don't think that would do any good.  rxvt is a posix program and
expects an environment where it has ptys that it can use.  Without pty
support it would likely complain loudly and refuse to run.

Again, I'm pontificating on something I know little about here, but I'm
guessing one solution might be some kind of kludge in the cygwin layer
that would attempt to detect when a native app is doing buffered writes
to a pty and autoflush after each call.  But, just a WAG.  It might even
be out of cygwin's control, if the buffering is done in the CRT of the
app.

Try piping the result to "cat -A", i.e.,

> cvs -d :ext:[EMAIL PROTECTED]:/cvsroot/gcc co -D 8/25/2004 gcc 2>&1 | cat -A

You have a ^M (carriage return) character embedded in the output of cvs,
and the cat command will show the full output.

I wasn't in pedantic mode when writing that.  Let's assume that when Luke
played with the permissions, he's already changed this to some sufficient
value, like, say, the owner may read files in the own directory...

[APPS] ping python maintainer (and others) - Launching cygwin apps from cmd.exe vs. softlinks in /bin

[Dave Korn]

  I thought this topic ought to be on the -apps list, but the description
does say...

"It is not (with one exception) for bug reports, "it would be nice", or "how
do I" type of musings."

... so I'm mentioning this here instead.

  It's quite a common idiom in cygwin packages (based on longstanding unix
tradition) to have an executable that has the version number appended to it,
and then use a soft-link to provide an unadorned executable, e.g.:

[EMAIL PROTECTED] /bin> ls -la python*
lrwxrwxrwx1 dk   Users  13 Jan  5  2004 python.exe ->
python2.3.exe
-rwxr-x---+   1 dk   Users4608 Dec 30  2003 python2.3.exe


  Now, in this particular case "python.exe" is a cygwin old-style softlink
rather than a windoze .lnk-style shortcut.  This means that it can't be
invoked from cmd.exe; because a cygwin old-style softlink is basically a
text file, cmd.exe notices that it has no PE/MZ header, but since it's got a
.exe extension, cmd.exe thinks it has to be _some_ kind of executable, so it
guesses the only thing left - that it's an old 16-bit MSDOS .com-type
executable - and invokes NTVDM, which loads the file into memory and starts
happily executing ASCII bytes as opcodes (or at any rate, happily until it
gpfaults within the first few bytes).

  It's a shame, because most normal cygwin apps can be invoked either from
bash or from cmd.  And it's a shame in particular for Python, because the
cygwin and win32-native versions are very close to functionally
interchangeable, and if it wasn't for this slight hiccup they could be used
that way (with only a little attention to not using OS-specific features in
your python scripts).

  Using a non-symbolic link works for me; "ln /bin/python2.3.exe
/bin/cmd-invokable-python.exe" gets me something I can invoke from either
DOS/cmd or bash/sh.  

  Using a new-style symlink fails in several interesting ways:

1) Well, there's the .lnk extension to take into account, which is a minor
nuisance because you can't invoke it with just 'python.exe'.

2) Also, "ln -s" sets utterly wrong ACLs on the link it creates, such that I
have no "read and execute" permission.  (I think this is a genuine bug, but
I'll start a separate thread for it once I've confirmed that.)

3) So after I modify the ACLs, and invoke it by typing
"shortcutname.exe.lnk" at a cmd.exe shell, something very bizarre happens:
it forks off from the shell, and both cmd.exe and the python exe are running
simultaneously, connected to the same stdin and fighting each other for
chars from my command lines.  [ Can I refer to this as "a terrible forking
bug" without getting banned from the list? :-O ] 

  Now, I know that using a hardlink has the effect on FAT filesystems of
simply duplicating the file, and so this might not be a desirable or
possible solution to adopt in the majority of cases.  I'm not sure how
compatible it would or wouldn't be with the cygwin packaging scheme, for
starters.

  But the python executable is a special case, because it's tiny: 4608
bytes, because all the actual functionality is in a .dll, and the .exe
simply has to load the .dll and call out to it.  So in this particular case,
(and any similar ones, such as zsh, perl, and conceivably even tclsh,
although at 16kb the waste/redundancy starts to become more worth
considering) it might be entirely reasonable to simply provide two identical
duplicate .exes in the package, mightn't it?

Re: Running cmd programs in cygwin / rxvt

Brian Dessent wrote:
Andrew DeFaria wrote:
What you're seeing is caused by the output of the program going 
through a tty (or pty as the case may be.) When you run it from a 
straight cmd.exe it's not using tty code (unless you have CYGWIN=tty 
set.) From my meagre knowledge of the subject it has to do with the 
program not explicitly flushing stdout (or not knowing that it needs 
to as this is usually not required under windows.)
Is there a CYGWIN setting to tell rxvt not to use ptys?
I don't think that would do any good. rxvt is a posix program and 
expects an environment where it has ptys that it can use. Without pty 
support it would likely complain loudly and refuse to run.

Again, I'm pontificating on something I know little about here, but 
I'm guessing one solution might be some kind of kludge in the cygwin 
layer that would attempt to detect when a native app is doing buffered 
writes to a pty and autoflush after each call. But, just a WAG. It 
might even be out of cygwin's control, if the buffering is done in the 
CRT of the app.
Cygwin does do some of it's own coding that is conditionally compiled 
right? Why not conditionally compile stuff to get ptys (or some other 
equivalent) to function with native Windows apps that are currently 
having problems with the concept of ptys?

I know I often point people to use rxvt because it's a lot better than 
that silly Windows window. However I often work with Clearcase and 
Clearcase's main command, cleartool, messes up WRT rxvt and ptys (as 
well as other tools), so I'm constantly explaining the problem. I'd just 
like a real solution to offer and to use.

I don't understand the internals of ptys vs. ttys and native console I/O 
nor why it's having the problem. I just deal with the result and would 
like it fixed if possible. Sounds like it may be a complex fix though. 
As I said I'm not sure why ptys are necessarily needed in the first 
place but admittedly I have not researched it.

rxvt is a port of a UNIX program.  UNIX uses ptys.  Windows doesn't
support the notion of ptys.

http://www.google.com/search?q=define:pty

If you want to run a standard windows window (i.e., a console window)
then that's what you get when you click on the cygwin icon.  The terminal
input and output is largely controlled by windows and cygwin has little
say over how characters are handled.  If it was as easy as just using
this, don't you think we'd have been doing this by now?

I understand that. But I like using rxvt much better WRT terminal

I never said it would be easy - just desired. Would it be possible to 
implement a command then that says exec this with tty's instead of ptys?

Cygwin ttys and ptys are the same thing.  You should be able to start a

mutt tries to put the person's name in the attribution but switches to
email address if there is no name.  I've never been able to find a method

Some more randomly-ordered points:

a) the cluster size can be as large as 32k, which means that even a
symlink takes up that much space.

b) FWIW, if the symlink is set up in a postinstall script instead of the
tarball, it'll be a new style symlink.

c) the code in spawn.cc currently treats any file with a .exe extension
specially, and passes it on to CreateProcess without looking into it any
more than that.  It could, technically, check whether the file is an
old-style symlink, and do the right thing in that case -- as always,
.

Thanks, but that does not answer my question.  I do not know what
daemons are running.  I did not start any.  I assume some are started in
the installation process but I don't know how to find out which they
are.  I just searched the FAQs for any other mention of "daemon" and
found none.  I have also checked the User's guide but it does not seem
to contain any relevant info that I can see.  There should never be any
users logged in remotely to my cygwin and if there is something I have
to do to enforce that, that's part of what I want to know.  I should
also be the only one using sftp, ssh, etc. With the previous version of
cygwin, I was able to sftp and ssh from cygwin to other machines but not
from other machines to  my desktop computer.  I hope that is still the
case.  I'll check it eventually, but as mentioned, I have a
more-than-full time job as other than an UNIX programmer or system
administrator and I cannot just stop and spend a month setting up
cygwin.  In the past I didn't have to.  The lack of relevant
documentation and the complexity of the current setup and install
process are extremely frustrating.

setup.exe does not, currently, start (or even install) any daemons.  Any
daemon setup is usually done by the corresponding *-config script.  Unless
someone writes a postinstall script that will install a daemon (unlikely,
and should be considered a packaging bug), you should explicitly add any
daemons before they are started.

The Windows equivalent of "daemons" is "services".  Does that help?

Unless you've added some services, there will be no remote users logged in
via Cygwin programs.

It would help more if you described the exact stumbling blocks and things
you didn't find in the docs and had to search for, or even provided
patches to the appropriate parts of the documentation.

re emacs problems

[Koskie, Sarah]

You're right John.  Thanks.  In fact, I later (after sending that email)
found that that was the problem and changed the home directory there.
Now the lines in the .login (copied from /etc/csh.login work correctly
for my tcsh shell.  

I'm still hoping someone can comment on what emacs I should install to
get the normal robust behavior I've come to expect from emacses.

Unrelated issue:  Is there a way to get related messages posted properly
as followons in  the mailing list archives without subscribing to the
mailing list?  I assume it's by replying to actual email from the
mailing list that messages are posted as replies rather than new
threads.  I can't see filling my email box with questions I don't for
the most part even understand, let alone have answers for, yet feel bad
about every message starting a new thread rather than being properly
appended to the previous thread.  I'm unwillingly sending mail using MS
Office Outlook 2003 until I find time to switch to something better.

  Fair enough, but what I really want is something that doesn't require my
makefiles to have to discriminate between what kind of python exe is first
in the path; I want them to be equipotent, and I don't want to have to
install things that aren't standard; I want a makefile that can be invoked
from either cmd.exe or bash, that can run on a system that has either cygwin
python or win32 python or both installed, that isn't sensitive to which one
comes in which order in $PATH, and that doesn't require anything extra to be
installed.  But I guess I could always use a makefile rule to create
python.bat in the objdir I'm building in hmm.  That might have been a
bit simpler than my current solution, which uses a fairly gross makefile
hack to search $PATH and some default install locations for any instances of
python.exe, then discards any which live in a ".../bin/.." subdir to try and
eliminate the cygwin version!

Don't give up so easily! While you're at it, you could also get rid of

If you use just "python", and the .bat is first in the path, it'll be
picked up.

You could also just create a python.bat in /bin, and cmd.exe will find
that, while Cygwin will use a symlink.

While CGF was obviously joking about the pty/tty "fix", my suggestion was
only half-humorous.  Look in spawn.cc around line 442...  FWIW, you won't
be fixing the behavior of cmd.exe, you'll be fixing the behavior of
Cygwin1.dll when a .exe program is invoked (before it's passed to Windows
via CreateProcess, i.e., the current action for .exe's and some others is
to *not* look inside the file to check whether it's a script or a
symlink).

Trust the FAQ: It's unsafe.
Esp. when you don't know what a daemon is. Just believe it.
A daemon is a long-running "satanic" background process.
See your Task Manager on the Process Tab.
One of the daemons you don't see is for example called "Explorer" (the 
windows desktop). This is one of the worst security holes on windows, 
regardless of cygwin.

sftp, sshd, cygserver, cron and all other cygwin services are also 
daemons, which share global data via cygwin1.dll. If you are running 
them as user, a possible intruder can gain permissions of this user.
If you run cygwin programs as service the intruder might gain 
permissions of the SYSTEM user.

  Hmm.  It should be in the source distribution itself, at
/usr/src/gdb-20030919-1/tk/win.

  Let me see compare with the command line I got when I built insight from
source last time  I didn't use the cygwin sources, but they're currently
in fairly close sync with the repository I get the same warnings from
the compile as you did, but didn't get the fatal error from the missing
header.  So it should be instructive to compare the "-I" options in our
respective versions:

gcc -DHAVE_CONFIG_H -I. -I../../../../tools/gdb-6.1.1/libgui/src -I..
-DWIN32 -mwin32 -fwritable-strings -I/repository/tools/gdb-6.1.1/tcl/generic
-I/repository/tools/gdb-6.1.1/tk/generic
-I"/repository/tools/gdb-6.1.1/tk/xlib" -DHAVE_NO_SEH=1
-DEXCEPTION_DISPOSITION=int
-I/repository/tools/gdb-6.1.1/tk/generic/../unix
-I/repository/tools/gdb-6.1.1/tk/generic/../win -DTBL_VERSION=\"2.7\"
-DTBL_COMMAND=\"table\" -DTBL_RUNTIME=\"tkTable.tcl\"
-DTBL_RUNTIME_DIR=\"/usr/local/share/redhat/gui\" -DSTATIC_BUILD-g -O2
-c ../../../../tools/gdb-6.1.1/libgui/src/tclwinprint.c

  Ok, so your one has this strange include path to
/netrel/src/libtcltk/tk/xlib which my one doesn't.  Looks like maybe you
have an older version of the tcl/tk headers in your installation and somehow
it got chosen at configure time over the ones included with the gdb source
distro?  Also, there really shouldn't be all those "-I /usr/include"s in
there.  And what on earth are "/usr/include/../win" and
"/usr/include/../unix"?  Maybe configure has somehow failed to find
something and is using /usr/include as a default, no-hope-last-chance
fallback; and then bogusly concatenating relative paths onto it that would
have been relevant if it had found the real headers but make no sense when
just hoping they're in the standard system includes dir.  Yech.

Isn't the official plural "emacsen"? ;-)  I'm a vi person, so I don't know

Yes.  Two ways, in fact.  One works with programs that understand the
"mbox" format for e-mail (e.g., pine); the other is more generic, but
requires some effort.

> I assume it's by replying to actual email from the mailing list that

Right, that's the idea -- to get the actual message without subscribing to
the list.  For the "mbox" method, Google for "web archives raw text
site:cygwin.com" -- I posted a couple of recipes before (I've since
improved on the automation of the method, if anyone's interested).  The
second method is described in a help message you get from ezmlm (mail to
cygwincom>) -- namely, you can get a copy of any list
message by e-mailing to cygwincom>.  The trick
is finding out the message number -- the "Raw text" link is helpful here
as well; just look at the "From " line (first line of the raw text), and
the MSGNUM will be the digits between "cygwin-return-" and "-listarch-".

In any case, the second method above should work even with Outlook.

Try installing from your local directory.  That might work/avoid the problem.

Crontab issue

[Mogyorósi István]

Hello,
I spent quite a lot of time reading the subject and
I still dont have clear sight on the problem.
It is probably a permission/access sync issue
between Cygwin and NT.
But my case is NOT a network drive.
Case 1,
crontab -e [ logged in as Administrator ]
20 12 * * * /home/Administrator/mydate.sh [ my own script to exec ]
-
it works with the result written in my home directory.
mydate.sh is `date >mydate.txt`
Case 2,
crontab -e [ logged in as Administrator ]
25 12 * * * /cygdrive/e/otherpath/mydate.sh [ my second script to exec ]
-
this does not work.
My Error message in Eventlog is:
bla .. bla .. /usr/sbin/cron : PID 2356 : (Administrator) CMD
(/cygdrive/e/otherpath/mydate.sh 2>&1)
The access permissions for both shell scripts are identical.
The only difference is the path to execute.
If I install the service as Administrator, and try to start it
with the Service Control Manager it fails to start and
I get the error message in the Event Log:
... bla bla .. Cygwin_cron : PID 2260 : starting service
'Cygwin_cron' failed : execv: 1 , Operation not permitted.
Any comments welcome,

mydate.sh is `date >mydate.txt`
It's a good idea to specify the absolute paths for any commands or output
files.
Case 2,
crontab -e [ logged in as Administrator ]
25 12 * * * /cygdrive/e/otherpath/mydate.sh [ my second script to exec ]
-
this does not work.
My Error message in Eventlog is:
bla .. bla .. /usr/sbin/cron : PID 2356 : (Administrator) CMD
(/cygdrive/e/otherpath/mydate.sh 2>&1)
Hmm, looks like it *is* getting executed, but the output is lost?  See
the previous comment.
The access permissions for both shell scripts are identical.
The only difference is the path to execute.
Can you execute the latter script from the command line as Administrator?
If not, are the access permissions on both *paths* sufficient?  For a
script to be executable, all the components in the path to it have to be
reachable (i.e., the directories have to have at least the execute
permission).
If I install the service as Administrator, and try to start it
with the Service Control Manager it fails to start and
I get the error message in the Event Log:
... bla bla .. Cygwin_cron : PID 2260 : starting service
'Cygwin_cron' failed : execv: 1 , Operation not permitted.
This is a different symptom -- most likely the necessary DLLs in your /bin
are not executable by non-owners (i.e., SYSTEM, which is the user cron
will run under when installed as service).  A "chmod -R a+X /bin" should
help (you might also need to fix permissions for other files/directories
under /var, and maybe /lib, /share, and /etc).

OK how about a command that says start this Windows console mode

to stdin/stdout/stderr (short of starting a new window that is).

You should be able to start a command in a new console window with 
"cygstart" (q.v.).
Yes I can, however this starts it in another "Windows window" that does 
not easily resize, has crappy copy/paste semantics, colors and fonts. 
IOW all the reasons why I'm running rxvt! What I want is for it to run 
in the rxvt window so that I can have the nicer copy/paste, etc, not 
start a new window.

I think the point is that while it may be possible to make changes that do
what you want, they are not straight-forward and compromise POSIX
portability.  I also suspect that this is an area that requires real thought
and real effort by someone interested in taking up the effort.  If that's 
you, perhaps you want to get into the code a little bit and come back with 
questions about specific changes you'd propose.  To me, that seems the most
productive approach to a solution.

You keep offering simple-minded suggestions that boil down to "Well just
make rxvt work with these applications that don't like cygwin ptys, then."

Let me say it in big letters so that you will understand:

IT IS NOT POSSIBLE TO DO WHAT YOU WANT.

If it was possible, we would have done something long ago.

I'd be thrilled to be proved wrong or to have someone point me at
documentation which illustrates a way to do this.  Until such time, just
pounding on points from an admitted complete lack of understanding of
the issues is really pretty pointless.

And that's the one of the main features of rxvt.  But there are
trade-offs.  The fact that you don't like the trade-offs and desperately
want someone to fix them for you does not mean that the trade-offs will
go away if you keep offering uninformed suggestions.

rxvt is only a dessert topping.  It is not a floor wax.  No amount of
buffing is going to give you the shine on your floor that you are hoping
for.

Sorry Larry, but the point is that it is not possible to make the
changes.

So, you start a windows console app and you communicate with it, how,
exactly?  Open up a pipe?  Nope can't do that.  How then?

I'm not even sure it's possible to do.  If it is possible to do, it's
probably only possible on NT.

[ANNOUNCEMENT] New package: unison 2.10.2-1

[Schulman . Andrew]

The package 'unison' is now available in the Cygwin distribution.

Unison is a file synchronizer for Unix and Windows. It allows two
replicas of a collection of files and directories to be stored on
different hosts (or different disks on the same host), modified
separately, and then brought up to date by propagating the changes in
each replica to the other.

Please note that 'unison' contains the CLI (command-line interface)
version of Unison.  The GUI version will be released soon for Cygwin as
the unison-gtk2 package.

Re: Latest snapshot with XP SP2 and unison and cvs

[Karl M]

Hi All...
What can I do that would be usefull? I'm not sure how to tell where things 
are hanging, because unison-2.9.1 is a win32 program that invokes a cygwin 
ssh client.

I did confirm that it is a ssh client side issue. That is, an XP SP2 machine 
is fine as the server, but not as the client.

If I turn on the -v -v -v in ssh, the last thing I get is from a 
channel_input_window_adjust call.

No.  I don't see any change in Cygwin between 1.5.10 and 1.5.11 which
could result in a new behaviour on sockets.  The strace is useless.

SYSTEM user passwd

[Prakash Khemani]

On installing CYGWIN on my WinXP machine - it created a user called
SYSTEM in my /etc/passwd directory.

If I go to Control Panel -> User Accounts then there is only one local
user listed - and that is Administrator.

I can say login Administrator. It logs me in and immediately logs me out
- because the home dir and shell for Administrator are not set in
/etc/passwd.

I can't do the same with the user SYSTEM. What is the password for the
SYSTEM user - I tried the Administrator password but that didn't work.

My username, even though it is in the Administrators group, is not able
to read files owned by SYSTEM and having permissions same as -rwx--.

Please help me.

Thanks,
Prakash

The very same command works smoothly in a SGI workstation.
In both machines I have

it in a working directory which is mounted in binary (unix) mode, and in 
one which is mounted in text (DOS) mode.  In both cases, it works 
without error.

Now, that's started from a standstill (no previous checkout).
I note that when I do this 'beginning' checkout from a text mode working 
directory, the following files have '^M' endings:

*/CVS/Entries
*/CVS/Entries.log
*/CVS/Repository
*/CVS/Root
*/CVS/Tag
That might be a bad thing -- since it would tend to mess up future 
'update' checkouts (and cvs diffs, and ...) ***IF*** cvs is opening 
those files for READ in binary mode (that is, not translating the '^M's 
away).

But it doesn't.
I mean, cvs opens those files in the appropriate mode, stripping away 
the '^M's as far as I can tell.  I'm going to need more information.

Alternatively, the postinstall[1] script could be used to setup the
symlink using 'ln', instead of including it in the tarball and expecting
setup.exe to make it.  Wouldn't that make everyone happy?  (Except
perhaps the python maintainer, who now has an extra step...)

[1] And technically you'd need to remove it with a preremove script,
otherwise you'd get a broken link hanging around in your path after you
removed the package with setup.exe.

It's better to just fix setup.exe.

Re: SYSTEM user passwd

SYSTEM is a built-in user account on every[1] Windows machine.  Cygwin
did not create it, merely put a line in /etc/passwd that acknowledges
it.  The account would exist even if Cygwin had never been installed. 
Tip: Run Task Manager, select the "Processes" tab, and make sure the
"User name" column is enabled (View -> Select Columns if not.)  You will
see that all your services are run as this account.  If you are using XP
or later you will also see the additional accounts NETWORK SERVICE and
LOCAL SERVICE in addition to SYSTEM.

It is a built-in system account, it will not be listed there.  It cannot
be used as a normal account anyway.

There is none, you cannot log on to Windows as SYSTEM.  You can however
start processes as that user (as the above example with Task Manager
should show.)  Search/google the archives of this list for "sysbash" for
an example of how to get a bash prompt as the SYSTEM user.  However,
that's hardly ever required unless you're trying to debug a service that
will not start.

That's normal too.  That is how POSIX permissions work.  If you are not
the owner you have no r, w, or x access for a file with permissions
700.  If you want to read the file you'll either need to first either
change the ownership ("man chown") or change the permissions ("man
chmod"), or both.  Since this file was likely created by a service you
do NOT want to blindly change its ownership to "Administrator" as then
it will no longer be able to read/write the file, unless you modify the
permissions as well.

Cygwin ttys and ptys are the same thing.
OK how about a command that says start this Windows console mode
application using whatever it is that will make it happy enough to talk
to stdin/stdout/stderr (short of starting a new window that is).

You keep offering simple-minded suggestions that boil down to "Well just
make rxvt work with these applications that don't like cygwin ptys, then."
Let me say it in big letters so that you will understand:
IT IS NOT POSSIBLE TO DO WHAT YOU WANT.
If it was possible, we would have done something long ago.
I'd be thrilled to be proved wrong or to have someone point me at
documentation which illustrates a way to do this. Until such time, just
pounding on points from an admitted complete lack of understanding of
the issues is really pretty pointless.
You should be able to start a command in a new console window with
"cygstart" (q.v.).
Yes I can, however this starts it in another "Windows window" that does
not easily resize, has crappy copy/paste semantics, colors and fonts.

And that's the one of the main features of rxvt. But there are
trade-offs. The fact that you don't like the trade-offs and desperately
want someone to fix them for you does not mean that the trade-offs will
go away if you keep offering uninformed suggestions.
rxvt is only a dessert topping. It is not a floor wax. No amount of
buffing is going to give you the shine on your floor that you are hoping
for.

Well my mom always used to say: "It doesn't hurt to ask". Apparently she 
never met you!

Seriously though I was just asking whether it would be possible and 
trying to gain an understanding as to the issues involved - you need not 
be rude about it. A simple, "that's not possible to do the way things 
are set up" would have sufficed.

Seems to me that you said similar things when I asked why does a bash 
process hang around when you close it via the X box on top and yet now 
rxvt does kill the bash process...

Cygwin: You'll come for the posix emulation layer, you'll stay for the
meaness.

What? Did I miss something?
Chris, this guy has no clue as to what he's talking about. He's worse 
than me when I first started.
He does not know how GPL works, he has no clue as to what Cygwin is or 
how it got started.
He's a musician pretending to be a programmer. But he's not a 
programmer. He does not know what POSIX is, or why its important for 
Cygwin, Unix, and Linux. He wants to fix programs that are already 
stable, such as cmd. If he wants to program a Windows program, he needs 
to buy Visual Studio. I am learning more and more about Cygwin as I work 
with it. I learn from my mistakes. Does he? He needs an attitude adjustment.
