Re: [dtn-users] regarding DTNSIM2

Hi Somreeta and Aggelis,
In  <dtn2>/servlib/bundling/BundleProtocol.cc, you can comment out line 100:
    //BundleProtocl::register_processor(new PreviousHopBlockProcessor());

This will disable processing the Previous Hop Insertion Block so that you will be back in business. Neither of those implementations conform to the specification and they are not 100% compatible with each other – one includes a trailing null character after an EID string and the other does not. The specification says that the EID should be broken into a null-terminated Scheme name and a null-terminated SSP similar to the Primary Header dictionary. I believe ION 3.3 has been updated to the specification format which will be more incompatible with the current DTN2.9 implementation.
Regards,
DZ

hello somreeta
This reply is not related to your question but to a previous post that you asked n this list related to dtn-ion interoperability:

in a post that you send to dtn-users about interoperability isues between ion and dtn2
you said that you had a problem where

somreeta dtn% [1411747528.640888 /dtn/bundle/protocol error] error parsing previous hop eid 'dtn://somreetadtn.dtn

[1411747528.640911 /dtn/bundle/protocol error] consume: protocol error handling block 0x5
[1411747528.640922 /dtn/cl/tcp/conn/0x7f7268000940 error] protocol error parsing bundle data segment
and at the reply from  Yang, Yueli
it had attached two configuration files where they tested dtn 2.9.0 and ion 3.21
with success.
----------------
Hi Somreeta:

We recently successfully validated ION-DTN interoperability with the attached configuration files.

We have two hosts, both running ubuntu 14.04:
“tango” running ION-3.2.1 with the attached tangoion.rc file.
“ballet” running DTN-2.9.0 with the attached balletdtn2.conf file.

Hope this helps your debug of sending from ION node to DTN2 node.

Yueli Yang
-----------------
in our tests we had success with ion dtn interoperability with only with ion version
3.0.1
Did you have success with the conf files that Yeli sent you?
Also since in the mailing list archives i cannot find yelis configuration files
could you please send me those files ?
Thanks and regards

Hello all,
Can anyone please provide me the DTNSIM2 simulator. I can't download it from the site http://watwire.uwaterloo.ca/DTN/sim/
