Ma'am I have got a question like The following is an invalid TCP header dump. Justify the existing error/s and write the corrected TCP header. AF08 001 7 0000 OOA5 0000 OAO 1 8000 0800 0000 OOA2 How to find answers for this ? Looking forward for your reply!
Let us call four numbers as one section in the given tcp dump. There are 10 sections given. Replace the letter O with all zeros in 4th , 6th and 10th section. 7th section will become 8020 bcoz we need to make the URG bit set ..this has to be set bcoz there is some value shown in urgent pointer field.

Mam, I have a doubt there is a PYQ in which they have given a TCP dump and are asking for what application layer protocol is being used ?
Can you post that question??

big fan mam
Thank you🙂.Share my channel information with other students.
ma'm what if there are two flag/segment
You can use plus(+)..for example, if both ACK and SYN flag value is 1, then the type of the segment is SYN+ACK.
What are the options
The options are MSS, Window Scaling, Selective Acknowledgements, Timestamps and No-operation.
Mam if all flags are 0 then segmentation type?
Segment will be one or the other type..it cannot have all flags as zeros.
thanks mam
