3 dccp2tcp - convert DCCP packet captures to TCP captures for analysis with B<tcptrace>
7 B<dccp2tcp> [-d] [-V] [-h] [-y] [-g] [-s] I<input_file> I<output_file>
11 B<dccp2tcp> takes a tcpdump packet capture of DCCP connections and converts it to a symantically
12 equivalent TCP capture for analysis using standard TCP tools like B<tcptrace>.
14 In order to utilize this program effectively you will also need B<tcptrace>, which you can download
15 from http://www.tcptrace.org and the version of B<xplot> available from http://www.tcptrace.org under
16 "Useful Companion Programs".
18 B<dccp2tcp> only supports DCCP CCID 2 with 48 bit sequence numbers at this time.
26 Debug, repeat for additional verbosity
38 Shift the window line (yellow) in B<tcptrace> to the highest received acknowledgment.
39 Normally this line is just a constant amount more than the ack number(i.e. useless).
43 Shift the ack line (green) in B<tcptrace> to the highest received acknowledgment.
44 Normally this line is the standard TCP ack number, which, for DCCP, translates to
45 the highest contiguous acknowledgement in the ack vector.
49 Converts the DCCP ack vector to TCP SACK blocks. Specify B<-s> twice to only see
50 those Ack vectors with loss intervals in them.
