At first glance your configuration files look fine. 

Try re-running both dtnd executables with '-l debug' to turn on verbose debug logging. You should be able to look through the logs to see the point at which the bundle is received from the application, then trace to make sure that it got matched by the routing code to the correct link, and that the link connection is opened successfully. If you're still stuck, post the output to the list and I can take a look.

The idea is that it's an internal protocol exported by the daemon, and given that I don't know the inner workings of XDR either, and have at times changed the particular functions used by XDR, I haven't taken the time to spec out the protocol. However, the application side of the implementation is structured in such a way to make it easy to pull into different implementations. One thing you could think about doing is to use swig or some such tool to build python wrappers around the dtn api functions, but still use the C based implementation to do the actual communication with dtnd. As to your specific question, the XDR type I used for the endpoint id is a fixed length opaque buffer of bytes to prevent each side from having to malloc/free each time an endpoint id is transmitted. As such there's no need for a length since XDR on both sides already knows the length of the byte range to follow (it's always 256). -m On Sep 4, 2006, at 12:36 PM, Darren Long wrote: > Hi, > > [Resent due to prior use of wrong outgoing account and in > anticipation of 'delay tolerant moderation'] > > Over the weekend I started knocking up a python proxy-server for > the DTN2 dtnd's client API.

Hi Zack.
 
perhaps you should try the following:
 
at node1
erase line "link add link_tcp2 node3:5000 ONDEMAND tcp"
change line "route add dtn://node3.dtn/* link_tcp2" to "route add dtn://node3.dtn/* link_tcp0"

I think it's ok.
 
at node3
erase line "link add link_tcp2 node1:5000 ONDEMAND tcp"
change line "route add dtn://node1.dtn/* link_tcp2" to "route add dtn://node1.dtn/* link_tcp1"
 
So you are telling node 1 it needs to send the bundles to node3 va link_tcp0 (node2) and node 3 should send the bundles to node1 via link_tcp1 (node2)
 
please tell me if it works.

Hi Zack.
 
perhaps you should try the following:
 
at node1
erase line "link add link_tcp2 node3:5000 ONDEMAND tcp"
change line "route add dtn://node3.dtn/* link_tcp2" to "= ;route add dtn://node3.dtn/* link_tcp0"
 
at node2
I think it's ok.
 
at node3
erase line "link add link_tcp2 node1:5000 ONDEMAND tcp"
c= hange line "route add dtn://node1.dtn/* link_tcp2" to "route= add dtn://node1.dtn/* link_tcp1"
 
So you are telling node 1 it needs to send the bundles to node3 v=EDa = link_tcp0 (node2) and node 3 should send the bundles to node1 via link_tcp1= (node2)
 
please tell me if it works.
 
yours Gerardo. (sorry by my poor English :-) )

After reading plenty of C/C++, much sniffing of packets using Ethereal and much hair-pulling, I'm happy to say I can now register an end-point (small step for mankind, massive step for me). Anyway, to the main question. Is there a document describing this interface that would make this task easier? Secondly, in order to get the registration message to be correctly parsed by the server (and to look like a real message seen in Ethereal), I had to chop off a 32-bit size field that preceded (and described the length of) the endpoint ID string in the XDR encoding. I used an opaque packing for the string, as per the dtn_types_xdr.c function xdr_dtn_endpoint_t|() ... any ideas why this might be? I'm pretty unfamiliar with XDR.

First of all, it depends on which version of dtnd are you using, since the logic for link reopening and closing changed significantly since the last release. Secondly, if you could run your experiment after running dtnd with info level logging turned on (at least), then that will be helpful to determine what's going on since you'll see all the events that are posted to the daemon. Running dtnd -l info is the easiest way to do this. Post the generated log output to the list if you're still having trouble (as well as verifying which version it is). -mike Received: from ug-out-1314.google.com (ug-out-1314.google.com [66.249.92.168]) by webbie.berkeley.intel-research.net (8.11.6/8.11.6) with ESMTP id k81JPXY21941 for ; Fri, 1 Sep 2006 12:25:33 -0700 Received: by ug-out-1314.google.com with SMTP id j40so1046335ugd for ; Fri, 01 Sep 2006 12:25:32 -0700 (PDT) DomainKey-Signature: a=rsa-sha1; q=dns; c=nofws; s=beta; d=gmail.com; h=received:message-id:date:from:to:subject:mime-version:content-type:content-transfer-encoding:content-disposition; b=teUCc+kZkPRF7fMe41btnZs2+XwGUTA74jbq0fzRpkz8avzRNzAGn7jKw5tnF3SBleZD+XswmCvzCtZlMAbSkaFdU+z9VkVYlvYg/CaDjq8QkzN5vnpDS8/0E0Pxs9ValbYWmgQQ1T9yWxbLNyoueZTCz75a6EvG0nvaFl/Ng4w= Received: by 10.67.117.18 with SMTP id u18mr1388592ugm; Fri, 01 Sep 2006 12:25:32 -0700 (PDT) Received: by 10.67.25.11 with HTTP; Fri, 1 Sep 2006 12:25:31 -0700 (PDT) Message-ID: Date: Sat, 2 Sep 2006 00:55:31 +0530 From: "Zahir Koradia" To: dtn-users@mailman.dtnrg.org MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Content-Disposition: inline Subject: [dtn-users] Link status changing and taking a long time Sender: dtn-users-admin@mailman.dtnrg.org Errors-To: dtn-users-admin@mailman.dtnrg.org X-BeenThere: dtn-users@mailman.dtnrg.org X-Mailman-Version: 2.0.13 Precedence: bulk Reply-To: dtn-users@mailman.dtnrg.org List-Unsubscribe: , List-Id: discussion/answers list for users of the dtn reference implementation List-Post: List-Help: List-Subscribe: , List-Archive: Hi, I have been experiencing huge delays in sending bundles from one node to another becuase links stay in states other than OPEN for a long time. I have set the links to ALWAYSON in the config with a hope that the links will not be "Unavailable" or "Opening" but that does not help. The links get into these states and take time of the order of minutes to change the sate to OPEN. I dont understand why that happens. The states take time to change even when nothing else is happening in the network. I am not sure what causes the states of the links to change but was not sure if this is related to the work I am doing or it has been observed before. Are there any known work arounds/hacks? Thanks, Zahir Koradia
