telnet is a tcp service, that's why Net::Telnet can test for tcp connections only. If you want to test for udp ports as well, you should upgrade from Net::Telnet to IO::Socket. Anyway, it sounds like you're actually looking for a portscanner. If you run linux, I'd recommend you using nmap, see http://www.nmap.org/ .
