Premature end of script headers: CGI"

[fatturi]

I am having a lot of difficulty configuring httpd.conf to handle CGI.

I edited httpd.conf to add the Alias and ScriptAlias directives as
described in the nagios documentation.

I'm able to access the documentation, but i cannot manage the CGI commands, I keep getting the error: "Premature end of script headers: CGI"


i am trying to get nagios to work (Version: 2.0 Release: 0.b4.1)
with my FEDORA core 4, apache 2.0.43 webserver.

when i login to the specified url (http://localhost/nagios) i get to see the nagios index page,
but when i click the left hand menu the page will not load and will give me an internal server error.

when i browse httpd-error.log i find out it gives me this error:

[error] Pemature end of script headers: *.CGI referer: http://127.0.0.1/nagios/side.html

last but not least i'll put my httpd.conf additions for nagios:

ScriptAlias /nagios/cgi-bin/ /usr/local/bin/nagios/
<Directory "/usr/local/bin/nagios/">
AllowOverride AuthConfig
Options ExecCGI
Order allow,deny
Allow from all
</Directory>

Alias /nagios /usr/local/share/nagios/
<Directory "/usr/local/share/nagios/">
Options None
AllowOverride Authconfig
Order allow,deny
Allow from all
</Directory>

can be this problem due to a different users group? or a wrong setting of external cgi in http.conf?

any help?

thank you very much!

Maybe it's a problem with your CGI scripts? Are you sure they work correctly?

[fatturi]

yes i think, because they are the documentation's scripts...

the script cgi are in "/usr/lib/nagios/cgi-bin"
have you find a mistake

[Linuxnizer]

Just make sure your cgi-bin can execute Perl. change /cgi-bin with your cgi-bin path.

<Directory /cgi-bin>
SetHandler perl-script
PerlResponseHandler ModPerl::Registry
PerlOptions +ParseHeaders
Options +ExecCGI
</Directory>

might be SE-linux as well. Do you have it activated?

setenforce 0

and then try it again. Also - maybe you need some sort of perl module. Are you seeing any perl mod errors?
