Hi, This code is working in 32 bit ubuntu versions 14.04 and 16.04.
Also, this code is working in ubuntu 14.04 64 bit versions.
but it is giving socket creation failure error in ubuntu 64 bit. (linux-
image-3.19.0-25-generic 32/64 bit both working (ubuntu 14.04), linux-
image-4.15.0-45-generic (32 bit working for ubuntu 16.04) and linux-
image-4.15.0-47-generic ubunutu 64 bit gives error. Please suggest to
this issue to run on 64 bit ubuntu 16.04 and other machines.

htons(ETH_P_ALL));
