[users@httpd] Apache won't display index.cgi
I'm running Apache 2.0.58 and Apache2-AuthenRadius-0.6 for authentication
on a Sun Sparc V210. I was running another radius module but this one
seems better, so I switched. However, I can no longer get Apache to
display my index.cgi page when I browse to the directory it's in. It
prompts for authentication, which works, but all I get is a blank page. If
I manually add index.cgi to the url, my script runs correctly. I think
this is the relevant configuration. What have I missed?
BTW, if I remove authentication, the index page comes right up.

You might have better luck on the mod_perl list :
modperl@perl.apache.org
And, if Apache2-AuthenRadius-0.6 has any part written in C, my earlier
remark about mismatched versions may really be applicable.
Ok, never mind : from the on-line documentation of
Apache2-AuthenRadius-0.6 at
http://cpan.uwinnipeg.ca/htdocs/Apache2-AuthenRadius/Apache2/AuthenRadius.html
PREREQUISITES
For AuthenRadius you need to enable the appropriate call-back hook when
making mod_perl:
perl Makefile.PL PERL_AUTHEN=1
I would guess that's where your segmentation fault comes from.
Seems like one has to build mod_perl from source to use that one.
But go to the mod_perl list, there they might tell you if I'm wrong.

Note that whatever I wrote before might still help you determine
/precisely/ when this happens. There's lots of buffering going on all
over that might induce you in error.
Also, remember that anything your cgi prints to STDERR should end up in
the Apache error log. Might be worth inserting some debug prints there,
to see of it at least starts up.
Are you sure your mod_auth is really going to completion ? a
segmentation fault is hard to achieve in a cgi script.
But it could be the result of using a mismatched version of an add-on
module.

That might indeed cause a real blank page..

Thanks, I guess I have a bigger problem than I thought. I'm getting these
errors in the apache server log after authenticating and during the time
my index.cgi script should run. I don't know what's causing that!

It may not, since you get a "blank" page.
In fact, this is certainly not "just a blank page". There are HTTP
response code and HTTP headers sent by the server which tell you what
kind of error occurred (in this case probably a "401 Unauthorized").
The first thing to do for this kind of problem is making sure of what
really happens.
There are 2 sources for that :
- the error log of the server : what's in it ?
- the browser itself.
For the browser,
- if you are using Firefox, get the HttpFox extension (or
LiveHttpHeaders if you have FF v 2)
- if you are using IE, get the Fiddler extension
(search Google for both)
These extensions allow you to see, in an extra browser window,
/everything/ that is sent or received by the browser, in a readable
format. That includes all request and response headers.
It will also show you other things that you may not even be aware of,
such as several invisible exchanges between browser and server before
you even see this blank page.
For the server, usually Apache modules write errors to the logfile, or
can be set to do so. Look for a "debug" parameter for the auth module
that you are using.
When you have done all of that, come back if you have a question.
Most probably you will not, because you will already have figured it out
by yourself.

Is it possible that the authentication module (whatever it is) you are using
overrides the default index page settings of apache? If thats so, it wud be
better to look into the paramters used with that particular module!
Since without the module, its working, this might be the reason. (sorry i
dont know much about the module you are using :()
