1. Problem Description:
Hello,
Here is my Apache user and group :
# grep -iE "user|group" httpd.conf
User #1025
Group #1025
# ps axo uid,gid,comm | grep http
1025 1025 httpd
1025 1025 httpd
1025 1025 httpd
Let's run the following example script in mod_perl :
# more test.pl
open(my $fh, ">", "/tmp/test.log");
print $fh "Your UID is " . $< . "\n";
my @groups = split '\s', $(;
print $fh "You belong to these groups: ";
print $fh $_ . " " foreach(@groups);
Let's see the result :
# cat /tmp/test.log
Your UID is 1025
You belong to these groups: 1025 1025
# ls -ln /tmp/test.log
-rw------- 1 1025 0 82 11 Apr 22:25 /tmp/test.log
Question :
Why does the file is owned by group ID 0 ?
It should be 1025.
In addition, the Perl script (and its processes launched using system()) can't
use files owned by group #1025.
Thank you,
Best regards,
Ben
