Error while bindin IBRDTN to my ethernet interface
Hello IBRDTN community,
I have found a very weird behaviour when using ibrdtn-0,10.2 with OpenWRT ATTITUDE ADJUSTMENT (12.09, r36088), the behaviour is the following, each time that I wan to start the dtnd daemon I get an error when binding it to my ethernet interface. I have looked into /tmp/ibrdtn.err and I get always the error *ERROR IPNDAgent: join failed on eth0; 22: setsockopt() *independently of the interface that I use
root@OpenWrt:~# tail -f /tmp/ibrdtn.err Thu Sep 8 15:49:37 2011 ERROR IPNDAgent: join failed on br-lan; 22: setsockopt() .1]:4550 Thu Sep 8 15:50:07 2011 ERROR TCPConvergenceLayer: bind failed (cannot bind socket with address [192.168.20.2]:4556) Thu Sep 8 15:50:07 2011 ERROR IPNDAgent: join failed on br-lan; 22: setsockopt() Thu Sep 8 15:52:09 2011 ERROR IPNDAgent: join failed on eth0; 22: setsockopt() .0.1]:4550 Thu Sep 8 15:53:54 2011 ERROR IPNDAgent: join failed on eth0; 22: setsockopt()
Has anyone experience the same?
Thanks in advance,
regards

The last two error messages are the result of binding to eth0 which does not have any configured address. Replace eth0 with br-lan in the configuration to get it working.
The "bind failed" error may the result of multiple instances of the daemon. Be sure that all instances are stopped before starting again.
Kind regards, Johannes Morgenroth

Hi Johannes,
I am afraid that the suggestion didn't work out, I have changed the interface to the br-lan and it stills refuses to work. As you can see below I have also changed to the wireless interface, and it happens the same issue. Any other suggestion? Perhaps some of the libs that I have installed are outdated?
Thanks in advance,
Bes regards

The remaining error you see is related to the discovery mechanism. By default it tries to bind to an IPv6 address, but your system does not support this. You can safely ignore this error or configure the daemon to join IPv4 only via the address option.

Hi Johannes,
I have set the discovery feature, but I still get the same error while binding
Mon Feb 17 13:44:43 2014 ERROR IPNDAgent: join failed on br-lan; 99: setsockopt() Mon Feb 17 13:44:43 2014 ERROR IPNDAgent: join failed on wlan0; 99: setsockopt()
What more can I do?I hadn't seen this error before when working with ibrdtn, so I don't know exactly how to face it.
Thanks in advance,
regards

Hello again Johannes,
Reading the mailing-list I found this post of yours https://mail.ibr.cs.tu-bs.de/pipermail/ibr-dtn/2014-February/000594.html , there you were telling the fact that OpenWRT has some flaw with the IPv6 get() function, how did you check this out? And what's more, is there any available solution or patch to be applicable? I ask it since I am suffering the same kind of error I was trying to figure it out; just mention that I don't have IPv6 package installed on my device and I do have the libnl-2.0 one.
Thanks again,
regards!

If the IPv6 module is not loaded, you can just ignore this error. Please test if the daemon is working even with the error.
