Cygrunsrv crashes when setting STDERR to /dev/null
Sun Mar 2 13:55:00 GMT 2014
I have Apache running via cygrunsrv on a WinXP system. It works fine. Apache can
even do a setuid on startup, so a 'ps -ef' looks like this:
UID PID PPID TTY STIME COMMAND
httpd 1604 1308 ? 14:26:47 /usr/local/apache/bin/httpd
SYSTEM 1308 1400 ? 14:26:47 /usr/local/apache/bin/httpd
httpd 896 1308 ? 14:26:47 /usr/local/apache/bin/httpd
httpd 536 1308 ? 14:26:47 /usr/local/apache/bin/httpd
httpd 612 1308 ? 14:26:47 /usr/local/apache/bin/httpd
httpd 560 1308 ? 14:26:47 /usr/local/apache/bin/httpd
As you can see, I have it running as 'httpd', an unprivileged user, which I created
without password and removed from the 'Users' group, so it cannot login.
Unfortunately, this doesn't work on a Win7 system. If I try the same configuration
in a Win7 system, the following message is logged in logs/error_log and the Service
[alert] (1)Operation not permitted: setuid: unable to change to uid: 1006
So, I set a password for the 'httpd' user and configured the Service to log on as
that user. This works, but now I cannot use cygrunsrv's -1 or -2 switches for
redirecting STDOUT and STDERR anymore.
cygrunsrv crashes if I set either one of them to /dev/null. If I unset them, it
Can anybody help?
