Re: [Plug] Simple CGI question (featuring RH6.0 and Apache 1.3)

By default, you have to put cgi programs in the /cgi-bin/ directory for
apache. If you have it configured for extensions, then you need to make
sure the name ends in .cgi.
Can you run the CGI from the command line?
./hello.cgi
What are the permissions on the CGI?
ls -l hello.cgi
-rwxr-xr-x 1 nobody nobody 319 Jun 25 12:26 hello.cgi
it it executable by other?
these are the most common problems with CGI programs. If all these
conditions are met, and you can run it from the command line, then
make sure it's returning a valid http header.
try this as a hello world cgi (if you have perl installed):
################################################################################
#!/usr/bin/perl -w
use strict;
use CGI;
my $q = new CGI;
print $q->header,$q->start_html(),$q->h1('hello, world'),$q->end_html();
exit 0;
################################################################################
Run it like this:
./hello.cgi < /dev/null
it should produce this output (when run from the cmdline):
################################################################################
stty: : Invalid argument
Content-Type: text/html
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN">
<HTML><HEAD><TITLE>Untitled Document</TITLE>
</HEAD><BODY><H1>hello, world</H1></BODY></HTML>
################################################################################
make sure the first line in the script points to your copy of perl...
