- Subject: Cron Running As UID 400
Hi,
I've been through a couple of problems already with cron and have
resolved all of them (thanks to this list!) except this last one. The
cron service is indeed running, but no jobs are ever run as described in
the crontab. A strange thing I've noted is that the user that the cron
service is running under is not the expected SYSTEM but the unknown 400
as:
$ ps -ef
UID PID PPID TTY STIME COMMAND
winwa02 904 1 ? Feb 23 /usr/X11R6/bin/XWin
SYSTEM 3912 1 ? Feb 23 /usr/bin/cygrunsrv
SYSTEM 1512 3912 ? Feb 23 /usr/sbin/inetd
SYSTEM 2616 1 ? Feb 23 /usr/bin/cygrunsrv

400 2228 1 ? 12:30:59 /usr/bin/cygrunsrv
400 536 2228 ? 12:30:59 /usr/sbin/cron
winwa02 2188 2504 7 12:37:47 /usr/bin/ps
Note that other cygrunsrv processes do indeed correctly run under
SYSTEM. I suspect that if my cron and its associated parent cygrunsrv
process were running as SYSTEM, then the cron jobs would execute per the
crontab. In fact, I manually ran /usr/sbin/cron as my user (winwa02)
and cron was indeed able to kick off the crontab jobs properly.
A relevant entry in the Windows XP Application Event log appears in full
when /usr/sbin/cron starts as:
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. You may be able to use the /AUXSOURCE= flag to retrieve this
description; see Help and Support for details. The following information
is part of the event: /usr/sbin/cron : PID 536 : (winwa02) ORPHAN (no
passwd entry).
The typical command line used to install the cron service was:
cygrunsrv -I cron -p /usr/sbin/cron -a -D -e "CYGWIN=tty ntsec" -d
"CYGWIN cron"
My domain /etc/passwd and /etc/group files are up-to-date.
As usual the output of the relevant sections of cygcheck -svr appears
below:
