how to change hostname and domain name ?

[Eric_83]

I have a dns server .

I want to change dns server's hostname and

domain name .

I modified /etc/hosts , /etc/resolv.conf

I restarted the named daemon .

But when I use nslookup command check the domain
I discovered there is no change in hostname.

how can i do ?

hi~

you can change hostname,

follow instruction:

# vi /etc/hosts (hostname change)

# /sbin/init.d/hostname start

# nslookup your_hostname

after, confirm the /etc/nsswitch.conf

follow instruction:

# vi /etc/hosts (hostname change)

# /sbin/init.d/hostname start

# nslookup your_hostname

after, confirm the /etc/nsswitch.conf file

also you can change resolution suffix

#vi /etc/nsswitch.conf

hosts: files [NOTFOUND=continue] dns

hi,
Also change /etc/rc.config.d/netconf file

as you are running DNS , changinh hostnames and domainnames isn't that simple I'm afraid .. it depend where the server is going to get its data himself , is it set to use DNS for it's own domain and resolving or not ??? if it uses DNs then the chages need to be taken care not only in resolv.conf but also in the DB (database files) created by DNS at startup, you wil physically need to alster the hostname in the DB file or alter things in the named.conf or named.boot and hostfile and run host_to_named script to remake the DB before restarting named...

The easiest way to change a systems host name and most network setting is set_parm. If you want to see everything then use:
set_parms initial.
That will take care of the sytem you are on. You didn't mention if that system is your DNS server also? If so you will have to look at /etc/named.boot to get the path to the db files and change the forward and reverse entries for the system there. Don't forget to restart named to re-read the newly edited db files.

If the DNS server is on another system then you will have to contact the SA on that system to make the appropriate DNS DB settings on the DNS server.

As Animesh as said, don't forget netconf file.

if you change the /etc/rc.config.d/netconf
and
/etc/hosts, /etc/resolv.conf
you can then do a /sbin/init.d/net stop
/sbin/init.d/net start
to reload the config.
set_parms will more or less do the same thing, but ask you to reboot.

Later,
Bill
