Premature end of script headers: CGI

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"

any help?

thank you very much!

The first output of a CGI program must be valid HTML headers.
Something like this:

Content-Type: text/html

Note the one empty line after Content-Type.

HTH,

thanks for your reply, 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?

It looks like Apache tries to run side.html as a CGI which is obviously wrong.
Can you post your entire httpd.conf? I suspect an error in there, not just in the part you added.

Hi

I am trying to configure nagios on my server i have configured the .cfg files and have got access to the web interface but after clicking any of the links i get an error:

Server Info:
-------------
Distro: Suse 10.2
S/w: nagios 2.9
Webserver: Apache 2.0

Server error!
The server encountered an internal error and was unable to complete your request.
Error message:
Premature end of script headers: tac.cgi
Error 500

My httpd.conf file section for this looks like:

ScriptAlias /nagios/cgi-bin/ /usr/local/nagios/sbin/

<Directory "/usr/local/nagios/sbin">
AllowOverride AuthConfig
Options ExecCGI
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</Directory>

Alias /nagios /usr/local/nagios/share

<Directory "/usr/local/nagios/share">
Options None
AllowOverride Authconfig
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</Directory>

Each link gives the same error with different cgi file referenced:

Premature end of script headers: tac.cgi

The actual file is in binary so can't read it. Any ideas on what i'm missing or what i can try.

Thanks for your help.
