*OpenIMSCore* Fail to restart bind9 in the installation step

Question

I have problem in installing the OpenIMSCore. I use ubuntu in VM Machine and followed the following posts to install OpenIMSCore Installing an IMS network heart. I went through all the first steps and now getting stuck at the step configuring DNS Configuration. I follow instructions:

**An example of a DNS zone file is present in the installation directory openIMS. Copy it into your DNS configuration directory: ser_ims cp / cfg / open-ims.dnszone / etc / bind /

Edit named.conf.local (still in / etc / bind /) to reflect this new zone (add the following lines): area "open-ims.test" {type master; file "/etc/bind/open-ims.dnszone";};

Check that the named.conf to do well call this file. For this, the following line must be present in the named.conf: include "/etc/bind/named.conf.local"; Add it if it does not.

Edit the file /etc/resolv.conf, delete (or comment on) the existing content and add the following lines: search ims.test open-domain open-ims.test nameserver 127.0.0.1

Note: At each reboot of the OS, this file will be overwritten by the Network Manager. So, make a backup of the file (we will use in our script automatically launch servers, we will see at the end of this tutorial): cp /etc/resolv.conf /etc/resolv.conf.ims

Edit the file / etc / hosts file and add the following lines: 127.0.0.1 localhost 127.0.0.1 open ims.test mobicents.open-ims.test ue.open ims.test presence.ope-n-ims.test icscf.open-ims.test scscf.open-ims.test pcscf. open-ims.test hss.open-ims.test

Warning: As before, make a backup of this file: cp / etc / hosts /etc/hosts.ims

Restart the DNS server: /etc/init.d/bind9 restart. Check that the configuration change has been taken into account (via dig): open-dig ims.test**

But when I restart the bind9, it show the failed error that I can not restart. Are there anyone have an idea how to get through this step?

Edit: Outputs of commands from comments, and named.conf:

$ pidof named
< no output >
$ sudo named-checkconf
/etc/bind/named.conf.local:9: unknown option 'area'
/etc/bind/named.conf:13: 'options' redefined near 'options'

named.conf.local:

area "open-ims.test" {
    type master;
    file "/etc/bind/open-ims.dnszone";
};

named.conf:

include "/etc/bind/named.conf.options"
include "/etc/bind/named.conf.local";
include "/etc/bind/named.conf.default-zones";
options {
    forward first;
    forwarders { {127.0.1.1;} ; };
};
zone "open-ims.test" IN {
    type master;
    file "etc/bind/open-ims.dnszone";
    notify no;
};

You've got multiple bind9 config errors here. One-by-one we'll fix them.

unknown option 'area':

area is not a supported bind9 configuration option. This is the biggest issue, so remove that entire section in your named.conf.local

'options' redefined near 'options':

In an Ubuntu setup, the 'options' section is in /etc/bind/named.conf.options. Revise that file accordingly, and put your new 'options' section configuration items into there, while commenting out what's there already. Then remove the 'options' section in /etc/bind/named.conf.

Uncaught issue: zone 'open-ims.test' is redefined

What the 'area' error above indicates is you tried to create a zone. You then create the zone in /etc/bind/named.conf directly, instead of in /etc/bind/named.conf.local where you tried to do this earlier. Take the configuration of the zone section you added to /etc/bind/named.conf directly, and add it instead to /etc/bind/named.conf.local instead. This should then make it a valid zone.

Once you've addressed the above errors...

Now do the following:

sudo named-checkconf

If this does not error, then proceed to restart the bind9 service...

sudo service bind9 stop
sudo service bind9 start
