RE: cron doesn't run (was: Re: login and ssh: can't authenticate)

I and several others have posted this same questions many times. AFAIK, no
one has a solution yet. We are all eager to find one.
Thanks.

Dunno.  Try the various hints on this mailing list.  Is CYGWIN=ntsec?
Is your /etc/group ok?

Yay!  You might want to add this to the cron.README documentation:

my mkpasswd ... > /etc/passwd created some password entries thus:


blah:unused:blah:blah:LastName, FirstName,U-blah,S-blah


LastName, FirstName is *no good*.

I changed all LastName, FirstName to FirstName LastName and cron
is happy.

Tried all that, didn't help me.

Check.  All of that is true for me as well, except I don't have
"binmode" in my CYGWIN.

Check.  Like I said, sshd works perfectly for me now, so I'm pretty
sure all the 'ntsec' and SYSTEM stuff is OK.  I'm pretty sure
SYSTEM can read everything under /var/cron, because I see "RELOAD
tabs/ryans" in the event logs.

I know the feeling :)  Unfortunately, some crucial step is missing, or
something has changed recently that is causing it to break.

Yup, I read the discussion on this list back in July 
(this thread:
http://sources.redhat.com/ml/cygwin/2001-07/msg00609.html)
that looked promising for me, but none of the advice there helped 
unfortunately.

A Lou Rayman at
http://sources.redhat.com/ml/cygwin/2001-10/msg01650.html was having a
similar problem on 31 Oct, as well as a Sergey Melnykov at 
http://sources.redhat.com/ml/cygwin/2001-07/msg00630.html,
but I didn't see any replies to their messages.

CYGWIN is "ntsec tty"

My /etc/group looks OK... I made it with mkgroup -l > /etc/group
SYSTEM is user and group 18, users are in a group called "Users".

I'm using the absolutely bleeding edge of every Cygwin package as of
yesterday.

Any other hints greatly appreciated.

My box is always connected to a lan so that shouldn't be a problem.

I don't have a problem to get cron working and I don't have a problem
to get a working user switch (with cron,ssh,telnet,ftp,rsh,...).  That
probably means, I'm doing something pretty automatically which I don't
think about anymore which other persons miss to do.  The thing is, I
really don't know what that might be.  I dare to say that I'm not
doing something mysterious.

I'm maintaining my /etc/passwd and /etc/group files with some care.
They contain always the SIDs of the users and groups.  I even added
some NT internal groups to my /etc/group file

local:S-1-2-0:2:
dialup:S-1-5-1:101:
network:S-1-5-2:102:
batch:S-1-5-3:103:
interactive:S-1-5-4:104:
service:S-1-5-6:106:
anonymous:S-1-5-7:107:
proxy:S-1-5-8:108:
enterprise domain controllers:S-1-5-9:109:
self:S-1-5-10:110:
authenticatedusers:S-1-5-11:111:
restricted:S-1-5-12:112:
terminal server user:S-1-5-13:113:
remote interactive logon:S-1-5-14:114:
local_svc:S-1-5-19:119:
netwrk_svc:S-1-5-20:120:
creator owner:S-1-3-0:130:
creator group:S-1-3-1:131:
creator owner server:S-1-3-2:132:
creator group server:S-1-3-3:133:

but I didn't do that on all my NT boxes!  It's more for testing
purposes and to have some supplementary groups in `id' output.

One thing I'm doing always is to change these lines in /etc/passwd

	Everyone:*:0:0:,S-1-1-0::
	Administrators:*:544:544:,S-1-5-32-544::

to

	Everyone:*:1:1:,S-1-1-0::
	root:*:0:0:,S-1-5-32-544::

and these lines in /etc/group

	Everyone:S-1-1-0:0:
	Administrators:S-1-5-32-544:544:

to

	Everyone:S-1-1-0:1:
	root:S-1-5-32-544:0:

But I _never_ change these lines

	SYSTEM:*:18:18:,S-1-5-18::	/etc/passwd
	SYSTEM:S-1-5-18:18:		/etc/group

The shell and the home directory are set up correctly for my
users in /etc/passwd.  Paths are given in POSIX notation.  I
never use /cygdrive paths in /etc/passwd.  I'm always setting
CYGWIN to `binmode tty ntsec' in the system environment.  All
important mount points are binary system mounts.  I don't expect
shares to work for processes changing the user context w/o
password and I don't expect to have user mount points then.

I'm always looking for the permissions of the concerned files and
directories.  SYSTEM must have permission to read all files in
/var/cron for example.  SYSTEM must have read permisssion on /etc
and the important files in it.  SYSTEM must be owner of the /etc/ssh*
files.

Hope that helps.  I'm really getting tired of answering that sort
of mail.  Everything should be in the mailing list archive now.

Here's a little more info from the Event Viewer.

cron says:

The description for Event ID ( 0 ) in Source ( /USR/SBIN/CRON ) cannot
be found. The local computer may not have the necessary registry
information or message DLL files to display messages from a remote
computer. The following information is part of the event: /USR/SBIN/CRON
: Win32 Process Id = 0x288 : Cygwin Process Id = 0x288 : (ryans) CMD
(/usr/bin/echo Cron works!).


and then it says:

The description for Event ID ( 0 ) in Source ( /USR/SBIN/CRON ) cannot
be found. The local computer may not have the necessary registry
information or message DLL files to display messages from a remote
computer. The following information is part of the event: /USR/SBIN/CRON
: Win32 Process Id = 0x288 : Cygwin Process Id = 0x288 : (CRON) error
(can't switch user context).


How do I fix this "can't switch user context" error?

Great!  Now I can ssh into my system... thanks Corinna.


Unfortunately, now cron seems to be broken:


From /etc/passwd:


ryans:unused_by_nt/2000/xp:12136:10513:Ryan T.
Sammartino,U-*****\ryans,S-1-5-******:/home/ryans:/bin/bash

My crontab has:

MAILTO=rsammartino@ea.com

30 13 * * * notepad


but, 1:30 PM came and went, and no notepad popped up.  Nothing else I
stick in there seems to work either, including simple "echo Cron works!"
type stuff (and yes, I do have ssmtp configured correctly).


I started cron with

cygrunsrv -I cron -p /usr/sbin/cron -a -D
cygrunsrv --start cron



Any help would be greatly appreciated.
