Uh... maybe it's just a terminology problem, or language problem, but... One doesn't _send_ DNS messages to a nameserver, one sends DNS _queries_. This is handled in the resolver library, or kernel networking handler, enabled by an entry of hosts: dns # or "dns files" or "files dns" ... in /etc/nsswitch.conf, and directed to an appropriate nameserver with an entry such as nameserver 13.169.12.144 # replace with the closest nameserver in your network in /etc/resolv.conf There can be, typically, three effective entries of nameserver ...; if the first is unreachable, then the second is tried, and so on. It is a shortcut to be able to leave off the domain if entries of domain somecollege.edu.vn search anotheruniversity.edu.vn,somebusiness.com.vn are also in /etc/resolv.conf For command-line access to DNS, use 'nslookup'. See also DNS-HOWTO, for example at www.linuxdoc.org/HOWTO/DNS-HOWTO.html, or the DNS-HOWTO.txt at your favorite documentation repository. > Thanks. Anytime.... Almost...
