Sorry, reviving this old thread because some debugging we were doing today raised a question I hadn't thought of.  For environments in which we can't synchronize clocks among nodes, for one reason or another, are there additional security issues?  I'm thinking of defense against replay attacks, coordination of the use of life-limited keys, that sort of thing.  Maybe that's only a concern for Kerberos and elsewhere has been superseded by other techniques?  Do those techniques fit well into a delay-tolerant architecture?

Reply-To: [email-masked]

On 2009-08-13 SourceForge rolled out multiple repository support 
per-project for Mercurial repositories (https://sourceforge.net/apps/wordpress/sourceforge/2009/08/05/mercurial-multiple-repository-support/ ).
Consequently some work will have to be done in order to restructure the DTNRG 
repositories so that they are in a supported configuration by SourceForge 
and so that the SourceForge documentation relating to use and administration 
of the repositories applies. 

The restructuring work will interrupt repository function for a short
period of time (a suitable evening). After which, you will want to start
pushing and pulling your changes from the new location. I shall update
the relevant wiki pages on http://www.dtnrg.org accordingly to refer to
the new source repository locations. Once completed the access
mechanisms as described in
https://sourceforge.net/apps/trac/sourceforge/wiki/Mercurial#Access
shall apply. For example to clone DTN2 from the new location and where
"USERNAME" represents your SourceForge.net user account.

hg clone ssh://[email-masked]/hgroot/dtn/DTN2 

If I do not receive posts to indicate otherwise I shall assume it is OK
to proceed with restructuring work outlined next Monday (05/10/09) at
23:00:00 UTC. The work should take no longer than two hours and I shall
post an update on completion. At time of transition I shall take the old
repositories offline and about month later decommission so as to avoid
confusion.

If this is not a good time I can reschedule. My apologies for the
inconvenience in this transition.

Subject: [dtn-interest] bundle expire malfunction??

--001485ea3cbc0774090474cfeb0b
Content-Type: text/plain; charset=ISO-8859-1

I am using DTN2-2.6.0 and flooding routing.  I believe I am experiencing
some odd behavior with the bundle expire command.

Here is my test scenario:

Nodes N1, N2, N3, and N4 all have entries in each others link lists.  Say N1
has a dtnsend command run on it while all links are closed which creates
bundle B1.  If a bundle info command is run on B1, then it is "queued" of
the following lists:all_bundles, pending_bundles,
FloodBundleRouter::all_bundles, link-0:deferred, link-1:deferred, and
link-2:deferred (link-0=N2, link-1=N3, link-2=N4).  Now if the link opens
with N3, the bundle is flooded to N3 and a bundle expire command is run on
the bundle on N1.  Here is the what I see on N1.  Bundle list status = NOT
PENDING.  Now if bundle info is run on it, it is "queued" on the following
lists:all_bundles, link-0:deferred, link-2:deferred.  If N1 now opens a link
with N2 and/or N4, the bundle is still flooded to the node and it is removed
from the corresponding link:deferred list.  When all known nodes have been
encountered, then the bundle finally disappears from the bundle list and is
deleted.  Note: if N1 were to open a link to a "new" node ex. N6, then the
bundle would be flooded to N6 as well.

I am curious, is this the intended behavior of the bundle expire command? I
was under the impression that expiring a bundle would simply remove it from
the bundle list immediately and delete the bundle.  Also, if this is the
intended behavior for bundle expire, is there a way to manually alter which
lists a bundle is a part of?

Thanks in advance for your comments/suggestions.

Or does every new porter just work it out from first principles?

Hi,

This refers to my TCP CL and bundle parsing/generation implementation in
Objective-C. It was tested in the Disconnectathon and is intended to be
publicly released but is not yet public. If there is interest in it please
let me know so I can gauge the level of interest and prioritize my time
accordingly;)

Cheers,

What iPhone implementation?  Didn't know there was one. Can you  
provide any pointers?

Subject: [dtn-interest] Hiroshima

I've just put in the meeting slot request for IETF-76 so
as of now DTNRG will meet in Hiroshima.

I've asked the secretariat to schedule us on Thursday or
Friday for one 2.5 hour slot. Folks who've been before will
know that actual scheduling is a very hard job for the
secretariat that won't get finalised until a couple of
weeks prior to the meeting. So plan accordingly.

As usual, one should register for the IETF meeting to
attend the DTNRG session. However, there will be an
experiment this time allowing for cheaper single-day
registrations (where you can transfer the day anytime
before you arrive). More useful for local folks I guess,
but there should be details on the IETF meeting registration
page. [1] (I can pass on RG feedback on this if you have
any.)

We'll start figuring out agenda items in a week or two,
but I've asked some local DTN researchers to give us
talks about their work, so I think we're set for an
interesting session that might foster some new
collaborations over time. More on that as things firm
up.

As usual, if you want a slot at the meeting, mail Kevin
and I with details (what you want to talk about and how
long you'd like).

Regards,
Stephen.

I've tried to compile dtn 2.6.0 source.
I'm following the manual and tutorials (/manual/index.html) and compiling the source on Ubuntu 8.0.4.

The compilation process work fine using the following code :

cd DTN2

But i can't move to the next step of tutorial (Starting dtnd and sending a ping) using the code :

daemon/dtnd -c /home/fred/dtn/dtn.conf --init-db

Because in my /daemon directory there's such no file name dtnd. How could I fix this. Is there anything missing?

Subject: [dtn-interest] New DTN Symbian implementation release available

Folks,

we just completed a release of DTNS60 a DTN implementation
(RFC 5050 + TCP convergence layer) interoperable with DTN2
(as just checked at the Stockholm DTN interop).  It has
also proven robust to challenged environments at ExtremeCom 2009.

It comes with a dtnping, dtnsend, and dtnrecv as simple apps
and DT-Talkie interoperable with our Linux/MacOS/Android tool.
Most importantly, this now comes with an API as well.

This is a follow-up on our earlier DASM work, but the author,
Anssi Turkulainen, has done a pretty much complete redesign
(with just some pieces left in until now).

Please check out its home page at:

     http://www.netlab.tkk.fi/tutkimus/dtn/dtns60/

where you can also find the binaries for the above tools.

The source code will soon be available at:

-------------------------------------------------------------------------------

                      ANNOUNCEMENT and CALL FOR PAPERS

                  The Second ACM International Workshop on
                       Mobile Opportunistic Networking
                               MobiOpp  2010

                     February  22-23, 2010,  Pisa, Italy

                      http://cnd.iit.cnr.it/mobiopp2010

                         sponsored by ACM/SIGMOBILE

-------------------------------------------------------------------------------

Opportunistic Networking is one of the emerging communication paradigms in
wireless mobile communications. Opportunistic networks are commonly 
defined as
a type of challenged networks where communication opportunities are based on
sporadic and intermittent contacts, disconnections and re-connections may
frequently occur, and the assumption on the existence of an end-to-end path
between the source and the destination is released. As compared to the 
legacy
MANETs, where an always-connected infrastructure-less network is assumed,
opportunistic networks are much closer to real pervasive networking 
scenarios,
where devices (with sensing capabilities) are carried while users move, 
and can
connect and disconnect continuously relying their communication chances on a
store-carry-and-forward approach. The aim of MobiOpp 2010 is to bring 
together
researchers working in this emerging area, thus also providing a 
reference event
for those working on self-organizing wireless mobile networks which usually
exploit the opportunistic communication paradigm. In this workshop we aim to
explore novel research issues related to all aspects of opportunistic 
networks.

Original contributions are solicited, being related to systems and protocols
design, development and analysis, in all areas of Opportunistic Networking.
Topics of interest include, but are not limited to:

  * Novel architectures
  * Routing protocols
  * Transport and reliability issues in opportunistic networks
  * Resource management techniques
  * Dissemination and replication techniques
  * Opportunistic networking in P2P systems
  * Social-aware opportunisitc networking
  * Middleware services in opportunistic networks
  * Opportunistic networking applications
  * Opportunistic networking in wireless sensor networks
  * Multimodal urban sensing
  * Security issues in opportunistic networks
  * Trust and cooperation in opportunistic networks
  * Mobility models for opportunistic networks
  * Tools and techniques for designing, analyzing and building 
opportunistic networks
  * Opportunistic networks testbeds and measurements
  * Opportunistic networks performance modeling

The workshop proceedings will be published by ACM. Extended versions of 
workshop
selected papers will be considered for possible fast track publication 
in the
Computer Communications Journal (Elsevier)
