First off, I apologize for asking a question that I know you get a
lot, but I have just spent the last hour and a half beating my head
against the wall and searching the internet trying to find a solution
with no luck.
Short version: I have an existing OpenBSD 4.0 box on which Apache
(version 1.3.29) is working properly, including execution of CGI
scripts. I am trying to move to a new machine with OpenBSD 4.1, so I
started with a fresh OpenBSD 4.1 install, which comes with the same
version of Apache as 4.0, and copied the httpd.conf file over from my
old machine. After starting the web server, however, I found that it
could not run any CGI scripts- always just giving me the following
error:
[Thu Aug 23 08:45:40 2007] [error] [client 127.0.0.1] Premature end
of script headers: /cgi-bin/test-cgi
[...snip...]
But anyway, this problem is fairly standard and is addressed here:
http://httpd.apache.org/docs/1.3/howto/cgi.html#butitsstillnotworking
As I mentioned in the first line, I was aware of that fact, and had
been searching the internet for a solution and trying different
things for the last hour and a half before asking for help :-)
The error means that apache is perfectly happy to launch your CGI
script, but the CGI is failing in some way.
The first thing to try is running the CGI from the command line:
cd /path/to/cgi-bin
./test-cgi

The test-cgi, as well as
the printenv both run fine from a terminal window.
Yep, as I also mentioned, tried that. Worked fine. I did manage to
fix the problem though-turns out that the problem was with Apache
being chrooted. The first line of the test script was looking for /
bin/sh, which, when chrooted, Apache could not find. I thought I had
checked this against my functioning box, but apparently I was looking
at the wrong box or something. At any rate, un-chrooting Apache fixed
the issue. Thanks for the help attempt!

I tried reverting
to the factory default httpd.conf, with no luck. The permissions on
the contents of the cgi-bin folder are as follows:
ls -l /var/www/cgi-bin/
total 212
---------- 1 root bin 99072 Mar 10 16:41 bgplg
drwxr-xr-x 2 root daemon 512 Aug 23 07:59 nagios
-rwxrwxrwx 1 root bin 268 Mar 10 16:32 printenv
-rwxrwxrwx 1 root bin 757 Mar 10 16:32 test-cgi
the cgi-bin folder itself has 755 permissions. The relevant section
from the httpd.conf file is as follows:
ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
#
# "@@ServerRoot@@/cgi-bin" should be changed to whatever your
ScriptAliased
# CGI directory exists, if you have that configured.
#
<Directory "/var/www/cgi-bin">
AllowOverride None
Options none
Order allow,deny
Allow from all
</Directory>
I have tried adding an "AddHandler cgi-script .cgi" directive to that
block, as one webpage I found suggested, as well as changing the
"Option none" to "Options ExecCGI". I did, of course, restart the
server between each configuration change. I have also tried with
various different CGI scripts, most of which come from a fresh
install. Nothing seems to make any difference- I still get the
"premature end of script headers" error. If this was linux, i'd say
check the SELinux settings, but it isn't. What am I missing here?
