- END OF TERMS AND CONDITIONS
-
- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- This program is free software: you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation, either version 3 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program. If not, see <http://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
- If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
- <program> Copyright (C) <year> <name of author>
- This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
- You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<http://www.gnu.org/licenses/>.
-
- The GNU General Public License does not permit incorporating your program
-into proprietary programs. If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library. If this is what you want to do, use the GNU Lesser General
-Public License instead of this License. But first, please read
-<http://www.gnu.org/philosophy/why-not-lgpl.html>.

Usage is as follows:
-ltptrace -t{encapsulation} ltp_file tcp_file [-d] [-b{block_size}] [-s{start session}-{end session}]
- -d is debug (repeat for additional verbosity)
- -t specifies what protocol LTP is encapsulated in. Right now, only udp and dccp are supported.
- -b specifies the LTP block size (NOT the bundle size) that is being used over this connection.
+ltp2tcp -t{encapsulation} [-v] [-V] [-h] [-b{block_size}] [-s{start session}-{end session}] ltp_file tcp_file
+ -v verbose (repeat for additional verbosity)
+ -V Version information
+ -h Help
+ -t The protocol LTP is encapsulated in. Right now, only udp, dccp, and sll are supported.
+ -b The LTP block size (NOT the bundle size) that is being used over this connection.
This information can't be determined from a packet capture, so if not specified
it defaults to is 500,000. If you set this value larger than your actual block size, the graph
- will contain empty spaces between each session, which is handy to separate sessions. However, in that case, tcptrace will report
- inaccurate, lost data statistics.
- -s requests a graph of only the specified range of sessions. Note that the session numbers are just the "session number"

+ -s Requests a graph of only the specified range of sessions. Note that the session numbers are just the "session number"
from wireshark, not the whole session id.
To generate the graphs run:
- ltptrace -tudp ltp_file.dmp tcp_file.dmp
+ ltp2tcp -tudp ltp_file.dmp tcp_file.dmp
tcptrace -lGt tcp_file.dmp
xplot a2b_tsg.xpl
1)Only handles one LTP "connection". There isn't a good way to separate
different LTP "connections" from new sessions of the same "connection".
Use Tcpdump filters to separate connections. Libpcap filtering could also
- be added in ltptrace.
+ be added in ltp2tcp.
2)Uses some special types from Linux (u_char, u_int32_t)
