Hi Folks,
I'm going around in ever-tightening circles trying to get
DirectoryIndex /mybin/myindex.cgi
directive to work against a directory within UserDir (ie ~user/public_html).
The platform is SuSE 9.3 with the default installation of Apache 2.0.53. For
the record, the config files are put into /etc/apache2, the ServerRoot
is /srv/www, DocumentRoot is /srv/www/htdocs, and the ordinary CGI is
in /srv/www/cgi-bin.
Ordinary CGI is working from cgi-bin, and also from within DocumentRoot after
applying a few modest config settings. Details later.
To make the DirectoryIndex directive work, I first tried putting the script
into /srv/www/cgi-bin, and after finally getting some clues about suEXEC and
the requirement for scripts to be "under the docroot" I have tried shifting
it to a /srv/www/htdocs/mybin directory. Permissions and owners of all
directories are locked down to the necessary paranoia level described in the
Apache manual page for suEXEC - because I started to see error messages
implying suEXEC is involved.
Here are what I think is the significant configuration directives. Directives
marked with ## are ones I've tried using or commenting out.
ServerRoot /etc/apache2 # to make config files relative
DocumentRoot "/srv/www/htdocs"
ScriptAlias /cgi-bin/ "/srv/www/cgi-bin/"
## ScriptAlias /cgi/ "/srv/www/htdocs/cgi/"
## AddHandler cgi-script .cgi
<Directory />
Options None
AllowOverride None
Order deny,allow
Deny from all
</Directory>
-- all other Directory below are Order allow,deny; Allow from all;
<Directory "/srv/www/htdocs">
Options +Indexes +FollowSymLinks
</Directory>
<Directory "/srv/www/cgi-bin">
Options +ExecCGI
</Directory>
<Directory "/srv/www/htdocs/cgi">
Options +ExecCGI
</Directory>
<Directory /home/*/public_html>
AllowOverride FileInfo AuthConfig Limit Indexes
Options MultiViews Indexes SymLinksIfOwnerMatch Includes ExecCGI
DirectoryIndex /cgi/myindex.cgi
<Limit ...
<LimitExcept ...
</Directory>
Currently the myindex.cgi script is a trivial piece of Perl:
#!/usr/bin/perl
use CGI qw(:standard);
use CGI::Carp;
print header, start_html('Test CGI Index'),
"Test CGI index ", `pwd`, end_html();
When it was installed in /srv/www/cgi-bin, and invoked as
http://myhost/cgi-bin/myindex.cgi then I get the expected output.
When it was installed in /srv/www/htdocs/cgi, and invoked as
http://myhost/cgi/myindex.cgi then I get the expected output.
When I try to invoke the script via http://myhost/~username it fails.
error_log contains:
[Thu Sep 08 21:24:12 2005] [error] [client 127.0.0.1] Premature end of script
headers: myindex.cgi
and suexec.log contains:

[2005-09-08 21:24:12]: command not in docroot
(/srv/www/htdocs/cgi/myindex.cgi)
and the browser shows: (slightly compressed)
Server error! The server encountered an internal error and was unable to
complete your request.
Error message: Premature end of script headers: myindex.cgi
If you think this is a server error, please contact the webmaster.
Error 500
I must be missing some essential detail, but I cannot understand what. What
does it take to make DirectoryIndex work with a CGI?
Thanks in advance,
Andrew Clarke
