OK I start from the begin:


$ whoami
  micekiller
$ cd /etc/
$ mkpasswd.exe -l -g > passwd
$ cat passwd

now I change my uid to 18

$ cat passwd
..
micekiller:unused_by_nt/2000/xp:18:18:micekiller,U-SN2307128\micekiller,S-1-5-21-1123561945-682003330-839522115-1000:/home/micekiller:/bin/bash
...

restart cygwin, then

$ whoami
  SYSTEM

$ cygrunsrv.exe -I cron -p /usr/sbin/cron.exe -a -D -d "damn cron" -e "CYGWIN=ntsec"

$ cygrunsrv.exe -S cron
$ cygrunsrv.exe -Q cron
  Service             : cron
  Display name        : cygwin cron
  Current State       : Running
  Controls Accepted   : Stop
  Command             : /usr/sbin/cron.exe -D

$ crontab -l
  # DO NOT EDIT THIS FILE - edit the master and reinstall.
  # (/tmp/crontab.1200 installed on Fri Oct  7 18:26:04 2005)
  # (Cron version -- $Id: crontab.c,v 1.8 2004/12/21 16:14:41 corinna Exp $)
  * 18 * * * /bin/date >> /usr/tmp/date.out 2>&1

the /usr/tmp permission is

$ ls -l /usr/
  total 648
  drwxrwxrwx+  2 Administrators SYSTEM      0 Oct  7 14:22 tmp
  ...

finally the cron.pid permission is

$ ls -l /var/run/
  total 6
  -rwxrwxrwx  1 SYSTEM         root     5 Oct  7 18:23 cron.pid
  -rwxrwxrwx  1 Administrators SYSTEM 616 Oct  7 18:20 utmp
  -rw-r--r--  1 SYSTEM         SYSTEM  24 Oct  7 18:09 ~x

I wait wait wait, but the /usr/tmp directory is always empty ...

$ ls -l /usr/tmp/
  total 0


In my Application Log there are only message about LST, RELOAD, EDIT
etc...

I'm desperate :-)

Thanks
	O.
