Dear All,
I want to check performance of IBR-DTN trough reconnect time but I still confuse how monitor that performance.

Dear Sebastian,
Thank you very much,
The problem already solve, I change the Api interface to Any, before I use Api interface = wlan0 because I use ad-hoc for my mesh network. So I think this item make the problem occur.
Thank's very much

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:

daemon. I
guess this failed in your case

I guess this worked on your host A, which explains why it can answer to pings

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.

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,
do you want to measure the time it takes until the connection is reestablished after the node is physically available again? Then you could have a log at the time stamped log files. (Start `dtnd -v --timestamp` to get the information.)
I don't know how you get the information when the network is back up again, but most likely, you can read this from dmesg or some other log files (syslog, ...). A bit of script/sed/grep/cut/...-magic and you should be done ;)
HTH, Stephan
