Segmentatio Fault while retrieving source and destination IP from Ip header

[Shameem Ahamed <shameem.ahamed () hotmail com>]

Hi All,


I am getting segmentation fault error, while retrieving the source and destn ip from ip headers.


Code snippet is given below.

packet is the last argument to the Callback function used in pcap_loop


===========================================
struct ip *ipHeader;    //IP Header

ethHeader=(struct ether_header*)packet;
ipHeader=(struct ip*)(packet+ETHER_SIZE);

printf("IP Version is: %d \n",ipHeader->ip_v);

printf("Source IP: %s \n",inet_ntoa(ipHeader->ip_src));
============================================

Regards,
Shameem
