This HTML entry

<!--#exec cmd="perl /var/www/cgi-bin/count.cgi" -->

works fine!!!

This one:
<!--#exec cgi="/cgi-bin/count.cgi" -->

Does not work and give me those errors at log:

[Wed Dec 7 16:05:51-2005] [error] (2)No such file or directory: exec of /var/www/cgi-bin/count.cgi failed
[Wed Dec 7 16:05:51-2005] [error] [client 192.168.168.101] Premature end of script headers: /var/www/cgi-bin/count.cgi

This is the count.cgi:

#!/usr/local/bin/perl
# Gif images should be named as 0.gif, 1.gif, ..., 9.gif
#

$| = 1;
$image = "pics/counter";
$count = "/var/www/cgi-bin/count.txt";

# Get counter number and increment it
open(COUNT,"$count") || die "Can't open count data file for Reading: $!\n";
$c = <COUNT> ;
close(COUNT);
if ($count =~ /\n$/) {
chop($c);
}
$c++;
open(COUNT,">$count") || die "Can't open count data file for Writing: $!\n";
print COUNT "$c";
close(COUNT);

# Determine counter width
$num = $length = length($c);

# Set Individual Counter Numbers Into Associative Array
while ($num > 0) {
$CHAR{$num} = chop($c);
$num--;
}

# Output gif images to Web server
$j = 1;
print "<img src=$image/0.gif>";
print "<img src=$image/0.gif>";
while ($j <= $length) {
print "<img src=$image/$CHAR{$j}\.gif>";
$j++;
}

Could some one tell me why?????????

Sound to me that you have a permissions problem, check the httpd.conf to see if the cgi folder has been set correctly and then check if the cgi is executable for the httpd user.

Forget to mention. Permissions were ok. Problem remains.

If the permissions were not properly set, I would not be
able to run it with <!---#exec cmd="perl....

Is the SAME script.

Tks.

Before you write anything back you should include a content-type header:
print "content-type:text/html\n\n";

Dear friends,

When I type at the prompt:
perl -w count.cgi

it returns:
<img src=pics/counter/0.gif><img src=pics/counter/0.gif><img src=pics/counter/4.gif><img src=pics/counter/2.gif><img src=pics/counter/2.gif><img src=pics/counter/2.gif><img src=pics/counter/7.gif>

AND it is working without the:
print "content-type:text/html\n\n";
WHITIN THE index.html page.

I have included this line BUT THE ERROR REMAINS.

The script is at /var/www/cgi-bin/
All permissions are ok (otherwise it would not run with perl)
It IS WORKING BUT ONLY WITH:
#exec cmd="perl ....."

When I point to the same script with CGI's <--!#exec cgi="...

Hello folks,

Got it to work:
My first line was WRONG!!!

IT MUST BE #!/usr/bin/perl. (I'm in Slackware)

Sorry for all the trouble and thank you all for the tips!!!
Linux rules.
Merry Xmas and Happy new Year.
