如何把internic的dns数据缓存到本地
我建立了dns服务器，配置文件如下
bupticet-222:/etc/bind# cat /etc/bind/named.conf
// This is the primary configuration file for the BIND DNS server named.
//
// Please read /usr/share/doc/bind9/README.Debian for information on the
// structure of BIND configuration files in Debian, BEFORE you customize
// this configuration file.
//
options {
directory "/var/cache/bind";
// If there is a firewall between you and nameservers you want
// to talk to, you might need to uncomment the query-source
// directive below. Previous versions of BIND always asked
// questions using port 53, but BIND 8.1 and later use an unprivileged
// port by default.
// query-source address * port 53;
// If your ISP provided one or more IP addresses for stable
// nameservers, you probably want to use them as forwarders.
// Uncomment the following block, and insert the addresses replacing
// the all-0's placeholder.
forwarders {
202.106.46.151;
202.112.10.36;
};
auth-nxdomain no; # conform to RFC1035
};
// prime the server with knowledge of the root servers
zone "." {
type hint;
file "/etc/bind/db.root";
};
// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912
zone "localhost" {
type master;
file "/etc/bind/db.local";
};
zone "127.in-addr.arpa" {
type master;
file "/etc/bind/db.127";
};
zone "0.in-addr.arpa" {
type master;
file "/etc/bind/db.0";
};
zone "255.in-addr.arpa" {
type master;
file "/etc/bind/db.255";
};
// add entries for other zones below here
bupticet-222:/etc/bind# ls
db.0 db.127 db.255 db.local db.root named.conf rndc.key
bupticet-222:/etc/bind#
发现有下面的资料：

系统是debian woody+bind9.
问题是:
1、 我该如何设置dns的缓存文件，从ftp.rs.internic.net下载named.root保存到/var/cache/bind后该如何命名？
2、如果某些域名变更了，本地缓存的文件会自动更新吗？

你帮助我，我也帮助你。
