Hi, folks,

 

I am developing a dissector, my tasks are:
 1. to get the “ip.len”
(the total length in IP header), 
2. using the ip.len to know how long the
packet would be and extract the last byte to my local variable. 

 

Could you guys please tell me how to get the IP’s total
length from IP header? 

How to extract the last byte of my packet? 



Any suggestions or advices would be appreciated. 

Thanks for your help


John
