| [mr700@linux mr700]$ nslookup

... i chisto i prosto si addwash drug/nqkolko DNS server-a.
    Po-dobroto reshenie spored mene e da si pusnesh lokalen keshirasht DNS server,
no za towa shte trqbwa da poglednesh DNS-HOWTO-to ;) i da si dobawish w conf-a:
--- cut ---
options {
        directory "/var/named";
        listen-on {
		127.0.0.1;	// shte se polzwa samo ot localhost
	};
	forwarders {		// ei tuka izrejdash nqkolko blizki DNS-a
		212.116.158.130;	// na dostawchika
		212.50.0.10;		// ns.spnet.bg primerno
        };
}
...
--- cut ---
i w /etc/resolv.conf da kajesh che nameserver-a e 127.0.0.1.
    Moje da ti se naloji da dobawish optziq 'query-source address * port 53;'.

    Ako nikoi ot eksperimentite ne uspee, wij kakyw firewall imash, spri go za
moment i probwai /za novi redhat like distibutzii - 'service iptables stop'/.

    Kysmet.
