Hello All:
 
This is probably more an apache issue than a perl issue. Still, I have been asking for help from apache folks and gotten none. So in the words of Mathezar of Galaxy Quest, "You are our last hope!"
 
There is a similar thread under "System and CGI - File Created but not the Content". I thought this was different enough to post separately becasue SELinux is off in my case and perl is the file writter.
 
#!/usr/bin/perl
use strict;
print "Content-Type: text/html\r\n\r\n";
print "<HTML>\n";
print "<HEAD>\n";
print "</HEAD>\n";
print "<BODY>\n";
my $filename  ="/var/www/html/DATA/kk.txt";
open(KK,">$filename");
close(KK);                                     # this line and the nex
+t 2 were not part of
system("chmod 666 $filename");                 # of the original code.
+ They were added to
open(KK,">>$filename");                        # see if changing the p
+ermissions would help
print "we are trying to write\n";
print KK "we are trying to write\n";
close(KK);
print "</BODY>\n";
print "</HTML>\n";

When executed the browser shows "we are trying to write", the /var/www/html/DATA/kk.txt file exists, it is 666, owned by apache and has zero content.
 
I am running FC4, Apache 2.0.54, perl 5.8.6, the server is not attached to the internet.
 
I have done what should never be done: 777 permissions on /var, /var/www, /var/www/html.
Below html I have a directory called DATA, also 777
user apache owns everything below var
setenforce 0 to remove SElinux
(basically, a desperate and ridiculous attempt to allow files to be written)
 
The odd thing is that the original program (from which this was extracted) up to 10am 9/17/2006. After that, the machine, untouched, exhibited the new behaviour.
 
All written files prior to 10 am 9/17 are apache 644 and have content. All written files after to 10am 9/17 are apache 644 and are empty.
 
1) I am probably not doing this the right way ... where should I be writting the files and how should I set upms and httpd.conf. I have been trolling google with "apache permissions" apachec cgi write files" and the like. If you have links to howtos, please send them!
 
2) In the above case, can I determine the reason and fix it? It would be nice to be able to dial back the permissions to something reasonable
 
Thanks in advance.
