can not connect to the deamon
Hi,
I get problem with my IBR-DTN connection. I make connection for 2 laptop (A and B) I have been setting A for time reference= yes, time_discovery=yes and B time_reference=no, time_syncronize=yes. When I test ping frm B to A is OK but ping A to B get a problem "can not connect to the daemon. Does it run" .
Could you help me for this problem, please.
regards.

Hi Johannes,
I make 4 nodes for my mesh network. 2 PC can connect each other but 2 PC cannot connect by using #dtnping dtn://name/echo. and there is a warning :bundle rejected: bundle has expired. I try to reinstall and change my OS become single OS Ubuntu 14.04 but the problem still occur.
Could you help me to solve the problem. regards.

Hi,
This implies, that the daemon on A is running, but was unable to bind the API port. (Because the dtn tools are also using a TCP port to communicate with a locally installed daemon). You can check whether IBR-DTN is bound to the API port (usually 4550) by using
netstat -lnp
(assuming you are using linux). It should be bound to a loopback interface.
Also, when the daemon is starting, you should get a message that the API has been bound to the correct interface.
For reference, on a correctly configured system it might look like this for netstat -lnp
tcp 0 0 127.0.0.1:4550 0.0.0.0:* LISTEN 7085/dtnd
You will find other lines with port 4556 for every interface where a TCP convergence layer is used and udp port 4551 if discovery is enabled.
The startup of the daemeon should look similar to this:
Sat Dec 20 21:15:37 2014 INFO NativeDaemon: IBR-DTN daemon 0.13.0-414 (build 63c8a50) Sat Dec 20 21:15:37 2014 INFO Configuration: Configuration: /tmp/ibrdtn.config Sat Dec 20 21:15:37 2014 INFO BundleCore: Local node name: dtn://sbase.dtn Sat Dec 20 21:15:37 2014 INFO BundleCore: Lifetime limited to 1209600 seconds Sat Dec 20 21:15:37 2014 INFO BundleCore: Pre-dated timestamp limited to 604800 seconds in the future Sat Dec 20 21:15:37 2014 INFO BundleCore: Forwarding of bundles enabled.

Sat Dec 20 21:15:37 2014 INFO NativeDaemon: using BLOB path: /mnt/sda1/ibrdtn/blobs Sat Dec 20 21:15:37 2014 INFO NativeDaemon: API initialized using tcp socket: loopback:4550 ^^This line is important, it tells, that the API port is successfully bound, so that tools such as dtnping/dtnsend etc. can talk to the daemon. I guess this failed in your case
Sat Dec 20 21:15:37 2014 INFO NativeDaemon: TCP ConvergenceLayer added on eth0:4556 Sat Dec 20 21:15:37 2014 INFO NativeDaemon: TCP ConvergenceLayer added on br-lan:4556 ^^This tells that TCP convergence layers are bound to the two listed interfaces. I guess this worked on your host A, which explains why it can answer to pings
