Greetings @grizzley, and thank you for your reply.
Sadly, following your advice DOES define
$domain, but doing so only
nullifies the
if loop. So the form fields never show up.
FWIW, the perl output in the web log reveals:
Use of uninitialized value $domain in string ne at dnsdig.cgi line 9.
Use of uninitialized value $domain in concatenation (.) or string at d
+nsdig.cgi line 18.
Can't call method "answer" on an undefined value at dnsdig.cgi line 19
+.
If I understood you correctly, the code I used was:
#!/usr/bin/perl -w
use strict;
use Net::DNS;
my $dns = new Net::DNS::Resolver;
my $domain;
if($domain ne "") {
print "<form action=\"dnsdig.cgi\" method=\"post\">
<input name=\"domain\" type=\"text\" value=\"\" />
<input type=\"submit\" value=\"Get MX\" />
</form>";
} else {
my $mx = $dns->query( $domain, 'MX' );
print "content-type:text/html; charset=utf-8\n\n";
print "$domain:\n\n";
foreach my $rr ($mx->answer) {
print "<br />", $rr->exchange, ' [<b>', $rr->preference, "</b>
+]\n";
}
}
Thanks again for taking the time to respond.
