8 5)Version and usage information in binary
10 1)Improved connection support to prevent odd behavior with multiple Resets
12 1)Debug flag (-d) is now Verbose flag (-v)
17 1)Multiple connection support and removal of source port != destination port restriction
18 2)Add warning about malformed ACK vectors
19 3)Speed up processing of connections with huge losses when running with debug enabled
21 1)Length checks to ensure entire DCCP header is captured
22 2)Correct command line option processing to allow stdin as packet source. This enables processing of compressed
23 captures using, for example, zcat.
29 1)Add double -s option to only show Ack Vectors/SACKS with loss events
31 1)Increase maximum number of TCP SACK segments to 4 (instead of two)
37 1)Complete Redesign of Encapsulation system. It now examines each protocol layer and removes encapsulation correctly.
38 If a protocol is not supported, the packet is ignored. As of right now the supported protocols are:
40 +Linux Cooked Capture (SLL)
47 1)Sequence number adjustments so that Tcptrace RTT graphing/statistics now work
53 1)Ack Vector computations were using one byte beyond the ack vector.
54 2)Ack Vector to SACK was using one byte beyond the ack vector.
56 1)All error output now goes to stderr
57 2)Multiple Debug Levels
58 3)Moved includes, struct defs, and some functions defs to a header file
60 1)Sync and SyncAck packets now have zero data and zero window. This makes them show up more easily in Tcptrace
65 Initial Public Release
67 1)Converts DCCP to TCP
68 2)Optional ack vectors to SACKS
69 3)Optional Window to highest ack
71 1)Supports only a single DCCP connection per capture.
72 2)Source Port can't equal Destination Port. If the two are equal, this program will get very confused.
73 3)DCCP MUST use 48 bit sequence numbers.
74 4)Checksums are not computed (they are zeroed).
75 5)Only converts those packet types used by the Linux implementation at this date
76 6)DCCP Ack packets show up as TCP packets containing one byte
77 7)Very little error checking of packet headers, it's research software afterall
