Hi all

I am using wireshark 1.0.2 for sniffing.

When i examine packets captured, for some packets it says

 (for TCP Header-----)
checksum: correct 
   good checksum : correct
   bad checksum : false

I could not understand what are these good checksum and bad checksum and how these are known.
Even though it shows checksum is correct, why it gives that comment?
any help?
 Thanks in advance.


Regards
Ramu.
