Question about the sequence number and next sequence number
Why the sequence number and next sequence number became to 1? Is it meaning something?
Why the sequence number and next sequence number became to 1? Is it meaning something?
If packet's Sequence Number
and Next Sequence Number
are equal that means the packet contains no data (TCP segment length = 0) in other words this is "pure ACK".
If you see such packet somewhere in the middle of a trace - this is unidirectional data transfer.
Keep in mind also 1
is not absolute Seq.n, but relative. If you want to spot real Seq.n you have to disable Relative Sequence numbers option
in TCP dissector.
Appreciated for your prompt reply!!! :)
