hi
I've installed the linux BIND 9.2.1 DNS server for the WIN2000 area network.
All WIN2000 server register themselves or via DHCP (reverse entries included) on the linux BIND DNS server automatically.
But I can find DDNS Entries from some WIN2000 client machines don't existing since 1 or 2 months.
How to solve this problem ?
I mean, if the machine doesn't exist anymore, the DDNS entry should be deleted automatically.
my BIND config file looks:
................................................
options {
directory "/var/lib/named";
auth-nxdomain yes;
multiple-cnames no;
cleaning-interval 60;
datasize default;
stacksize default;
coresize default;
files unlimited;
#recursion yes;
forwarders { X.X.X.X; X.X.X.X; X.X.X.X; };
forward first;
listen-on port 53 { 127.0.0.1; 10.20.1.10; };
listen-on-v6 { any; };
notify no;
};
zone "." in {
type hint;
file "root.hint";
};
zone "localhost" in {
type master;
file "localhost.zone";
};
zone "0.0.127.in-addr.arpa" in {
type master;
file "127.0.0.zone";
};
/Zone entry for domain xxxx.net.
zone "xxxx.net" {
type master;
file "/var/named/xxxx.net.hosts";
allow-update { 10.20.0.0/22; };
};
zone "0.20.10.in-addr.arpa" {
type master;
file "/var/named/10.20.0.rev";
allow-update { 10.20.0.0/22; };
};
zone "1.20.10.in-addr.arpa" {
type master;
file "/var/named/10.20.1.rev";
allow-update { 10.20.0.0/22; };
};
zone "2.20.10.in-addr.arpa" {
type master;
file "/var/named/10.20.2.rev";
allow-update { 10.20.0.0/22; };
};
zone "3.20.10.in-addr.arpa" {
type master;
file "/var/named/10.20.3.rev";
allow-update { 10.20.0.0/22; };
};
................................................
I've setuped my BIND via webmin.
kind regards
chris

Hi Chris,
The manpage of dhcpd.conf (5) states :
When the client's lease expires, the DHCP server (if it is operating at the time, or when next it operates) will remove the client's A and PTR records from the DNS database.
I would suggest you leave the named.conf, and investigate your DHCP server configuration.
Good luck.

Learn and explain...
