Thanks people, you where right. It's resolving issue. I just commented "127.0.1.1 biske-Inspiron-1525" line and now this works fine. Yupiii... Now my /etc/hosts file looks like: 192.168.1.3 biske-Inspiron-1525 # Added by NetworkManager 127.0.0.1 localhost.localdomain localhost ::1 biske-Inspiron-1525 localhost6.localdomain6 localhost6 # 127.0.1.1 biske-Inspiron-1525
# The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts
