I just start to learn CGI, I try to know some information about my server, my script looks like:

#! /usr/local/bin/perl

print "Content-type: text/html", "\n\n";

print "<HTML>", "\n";
print "<HEAD><TITLE>About this Server</TITLE></HEAD>", "\n";
print "<BODY><H1>About this Server</H1>", "\n";
print "<HR><PRE>", "\n";
print "Server Name:    ", $ENV{'SERVER_NAME'}, "<BR>","\n";
print "Running on Port: ", $ENV{'SERVER_PORT'}, "<BR>", "\n";
print "Server Software: ", $ENV{'SERVER_SOFTWARE'},"<BR>", "\n";
print "Server Protocol: ", $ENV{'SERVER_PROTOCOL'},"<BR>", "\n";
print "CGI Revision:    ", $ENV{'GATEWAY_INTERFACE'},"<BR>", "\n";
print "<HR></PRE>", "\n";
print "</BODY></HTML>", "\n";

exit (0);

But the output has no any information about server: 
Content-type: text/html

<HTML>
<HEAD><TITLE>About this Server</TITLE></HEAD>
<BODY><H1>About this Server</H1>
<HR><PRE>
Server Name:    <BR>
Running on Port: <BR>
Server Software: <BR>
Server Protocol: <BR>
CGI Revision:    <BR>
<HR></PRE>
</BODY></HTML>

I use Red Hat 7.2 version OS, and SSH both give me the same result, What is wrong? Thanks in advance!
