 |
|
I am trying to get tethereal to show me the Sequence and Acknowledgement numbers. But unfortunately tethereal rewrites the Seq and Ack number for some vague reason. If I run tethereal with the -V option it will tell me these numbers are relative. Is there any way I can solve this? And what use are the TSV (Timestamp Value, 32 bits) and TSER (Timestamp Echo Reply, 32 bits) values? Will they cause problems if you try to inject packets (that is the assignment & reason why I am trying to do this)?
