As long as the name can be resolved via DNS or WINS, nmap will be able to give you the hostname. http://insecure.org/nmap/ http://search.cpan.org/search?query=nmap&mode=all Here's an example: C:\>nmap -sP 192.168.0.0/24 Starting Nmap 3.95 ( http://www.insecure.org/nmap ) at 2007-09-09 12:58 Pacific Daylight Time Host 192.168.0.1 appears to be up. MAC Address: 00:09:5B:18:81:B0 (Netgear) Host graphic (192.168.0.2) appears to be up. Host rt.dev.com (192.168.0.10) appears to be up. MAC Address: 00:11:5B:55:1E:20 (Elitegroup Computer System Co. (ECS)) Host 192.168.0.128 appears to be up. MAC Address: 00:20:00:18:16:40 (Lexmark International) If you want to use a Perl script as a front-end to the nmap command, you'd want to use the Nmap::Scanner module. http://search.cpan.org/author/MAXSCHUBE/Nmap-Scanner-1.0/lib/Nmap/Scanner.pm -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
