Sorry for what I said isn't very clear. I did know when the /etc/hosts is
accessed in the OS.
What I want to know is whether the named access the hosts file. The /etc/hosts
file isn't in the client's system, but in the system of Local DNS server where
the 'named' task runs. For example:
In the /etc/hosts file of Local DNS server(LDNS), one line exists as
follows:
10.10.10.1 www.google.com
A client querys this LDNS to get the IP of 'www.google.com' (the client
may use dig,nslookup command. No host line is configured in /etc/hosts of this
client ), what IP will be returned to the client? Can the LDNS return
10.10.10.1 defined in the /etc/hosts to the client? maybe some special
configuration in named can support this feature.
Thanks,
Guanghua
