Hi all,
I am trying to calculate checksum of some data using python.

I am putting a sample ICMP header here and the correct checksum of that packet(Got this by sniffing network with wireshark)

DATA is "08 00 69 eb 8e 13 00 01"

And the correct checksum is "0xa9eb". as shown in the wireshark as correct.
