I have tried 2 way to run named. The one is add:" ./etc/bin/named start " in boot.local, the other is by using "chkconfig -a named". whichever I used, the named service seems to be started correctly.
But I cannot find the process of named by "ps -A " or Ksysguard.
If I want to restart the named: rcnamed restart, it prompt like this:
Shutting donw name server bind9 - Warning: named not running! done
Startting name server bind9 done

when I shut down my system, there is a message also like that above:
Shutting donw name server bind9 - Warning: named not running! done

So ,how can I really run named?

thanks at advance!

You need to set up the proper zone information and data files in order to use bind. Have a look at /var/log/messages and you'll probably see a bunch of errors that will tell you why named won't run.

---------------------------------------------------------
but I really have a named.conf .
At your standpoint , my named.conf has a wrong configuration? This is the reason why named quit imediately after start?
this is my named.conf below:

options {
directory "/var/named";
forward only;
//forward first;
forwarders {202.96.128.68;202.96.134.133;};
allow-query {127.0.0.1; 192.168.1/24;};
};

controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
zone "." IN {
type hint;
file "named.ca";
};

zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};

zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
allow-update { none; };
};

zone "lizardstudio.org" IN {
type master;
file "db.beyond_2000.org";
allow-update {127.0.0.1;};
};

zone "1.168.192.in-addr.arpa" IN {
type master;
file "db.192.168.1";
allow-update {127.0.0.1;};
};

include "/etc/rndc.key";
------------------------------------
In my local net ,this is the stand-alone server ,there is no slave DNS server .

_Where_ is your named.conf?

/etc/named.conf
/usr/etc/named.conf
I have put the file into these two directory.
I can see bind9 start success, but I still cannot find the process.

the process is exiting.

Have at look at the permissions of the file.
Have a look at whether or not not SuSE is running it chroot-ed. All I can recommend is that you fire up Yast and see how it's rigged up to start.

I changed the named run level to 35. What is the permissions of named.conf? The owner and the group are all root, only root can start or stop a process. Are there any other permissions?
You must be a expert of linux, would you like to teach me more about SuSE ? SuSE is a very alternative OS than others such as Redhat , Turbolinux and Mandrake, etc. There are too much more difference between other Linux OS.
