Add new domain manually

Hello,
I can't access ISPConfig from remote (firewall) but I have ssh access to system and urgently need to add new domain (first) to DNS.
Currently I have on the system only one domain on witch the system is working.
So the question is how to add new domain from SSH?
That's the files in /etc/bind:

Code:

root@raspberrypi:/etc/bind# ll
total 64
-rw-r--r-- 1 root root 2389 Feb 18  2015 bind.keys
-rw-r--r-- 1 root root  237 Feb 18  2015 db.0
-rw-r--r-- 1 root root  271 Feb 18  2015 db.127
-rw-r--r-- 1 root root  237 Feb 18  2015 db.255
-rw-r--r-- 1 root root  353 Feb 18  2015 db.empty
-rw-r--r-- 1 root root  270 Feb 18  2015 db.local
-rw-r--r-- 1 root root 3048 Feb 18  2015 db.root
-rw-r--r-- 1 root bind  463 Dec 14 18:20 named.conf
-rw-r--r-- 1 root bind  490 Feb 18  2015 named.conf.default-zones
-rw-r--r-- 1 root bind  242 May  6 10:33 named.conf.local
-rw-r--r-- 1 root bind  914 Oct  5  2016 named.conf.options
-rw-r--r-- 1 root bind  502 May  5 22:27 pri.newdomain.com
-rw-r--r-- 1 root bind 1020 May  6 10:41 pri.domain.com
-rw-r----- 1 bind bind   77 Apr 29  2015 rndc.key
d-ws-w--wT 2 root bind 4096 Apr 29  2015 slave
-rw-r--r-- 1 root root 1317 Feb 18  2015 zones.rfc1918
root@raspberrypi:/etc/bind# 

I added pri.newdomain.com with content:

Code:

$TTL        3600
@       IN      SOA     ns1.domain.com. xxxx.gmail.com. (
                        2015070308       ; serial, todays date + todays serial #
                        7200              ; refresh, seconds
                        540              ; retry, seconds
                        604800              ; expire, seconds
                        86400 )            ; minimum, seconds
;

newdomain.com.     3600   A        externaIP
www                   3600   A        externaIP

And edit named.conf.local

Code:

zone "domain.com" {
        type master;
        allow-transfer {none;};
        file "/etc/bind/pri.domain.com";
};
zone "newdomain.com" {
        type master;
        allow-transfer {none;};
        file "/etc/bind/newdomain.com";
};

But it is not enough or is something wrong. Thank you for help.
