Not pinging with host-name and can't ssh using hostname [duplicate]

Question

I have setuped a DNS server in Centos6.5 and its working with every client machines other than ubuntu, now i have issue with ubuntu While im trying to ping from desktop machine to DNS server as ping masterdns.arrivu.local i can't ping its return the as

sysadmin@localhost:~$ ping masterdns.arrivu.local
ping: unknown host masterdns.arrivu.local

But while i'm pinging with the ip address its working

sysadmin@localhost:~$ ping 192.168.1.15 -c 3
PING 192.168.1.15 (192.168.1.15) 56(84) bytes of data.

64 bytes from 192.168.1.15: icmp_seq=3 ttl=64 time=0.265 ms

3 packets transmitted, 3 received, 0% packet loss, time 1999ms
rtt min/avg/max/mdev = 0.265/0.386/0.450/0.089 ms

Even i have checked using host its returning the IP

sysadmin@localhost:~$ host masterdns.arrivu.local
masterdns.arrivu.local has address 192.168.1.15

My issue is i want to ping and ssh using hostname instead of ip as below

ping masterdns.arrivu.local ssh [email protected]

IM using Desktop machine with ubuntu

sysadmin@localhost:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu

My Desktop ip is 192.168.1.99

While i did a dig from my desktop i got the reply from DNS

sysadmin@localhost:~$ dig masterdns.arrivu.local

There is no iptables deployed in desktop machine's or what I'm using as DNS server too

[root@masterdns ~]# iptables -L
