[users@httpd] CGI Not working
I installed apache 2.0.43 and whenever I try to run a script I get the
following errors:
[Sat Nov 16 17:45:57 2002] [error] [client 192.168.0.100] Premature end
of script headers: classevals3.pl
I have run this script on other systems, so it must be something
specific to my system

help

There you go. The shell can't find the interpreter listed on the first
line of the script. Is perl really at /usr/bin/perl on that system? If
it is, you should try deleting the first line and retyping it to fix any
problem with non-printable characters. (Again, these are exactly the
two things I suggested could be wrong in my first email; I guess you
didn't follow my exact advice on how to test, but instead invoked perl
directly.)

There can be many many explanations: different environment, different
perl setup, etc. Very few of them are directly related to Apache.
What EXACTLY is the result when you run
./classevals3.pl from the command line?

I still don't understand why my classevals3 script runs on the machine
it was created on, but does not run on mine. The file can be downloaded

The script is now running, but it is not emitting proper HTTP headers.
According to the CGI spec, the first that that the CGI writes to stdout
must be a set of HTTP headers, followed by a blank line. Your script is
not sending proper headers. Instead, it is sending a line that looks
like
"6: test.pl".

Scripts run find from command line. I changed the owner to nobody, now
I get the following error:
[Sat Nov 16 18:04:43 2002] [error] [client 192.168.0.100] malformed
header from script. Bad header=6: test.pl
I really don't see what the problem is

Go to the directory containing classevals3.pl and type ./classevals3.pl
Most likely, this will fail, which means something is wrong with the
script. Some likely culprits:
- Not pointing to the correct location for perl on the first line.
- Bad dos->unix transfer, resulting in messed-up line-endings.
If the script succeeds from the command line, the most likely
explanation is an suexec config problem. Find and read your suexec log
file.
