Looks up whois server for domain on rs.internic.net
then looks up that domain on that whois server. really
really simple :)
#!/usr/bin/perl -w
use strict;
use vars qw/$server $sock $port @data $whois/;
use IO::Socket;
$|++;
$server = "rs.internic.net";
$port = "43";
die "Usage: $0 <domain>" unless(defined($ARGV[0]));
$sock = IO::Socket::INET->new(PeerAddr=>$server,PeerPort=>$port,Proto=
+>'tcp');
print $sock $ARGV[0],"\r\n";
@data = <$sock>;
undef($sock);
map {
if ($_ =~ /Whois Server: (\S+)$/) {
$whois = $1;
}
if (defined($whois)) {
$sock = IO::Socket::INET->new(PeerAddr=>$whois,PeerPor
+t=>$port,Proto=>'tcp');
print $sock $ARGV[0],"\r\n";
print <$sock>;
undef($sock);
exit(0);
}
} @data;
print @data;
exit(0);
