ERROR IPNDAgent: join failed on eth0; 99: setsockopt()
Hello,
I have just installed ibr-dtn on openWRT. I execute dtnd in this way dtnd -c /tmp/ibrdtn.config
but I get this ERROR ERROR IPNDAgent: join failed on eth0; 99: setsockopt()
Does anybody know why? Any comment/help is very much appreciated.
Thank you very much, Adriano
In my config file net_lan0_interface = eth0
and my network configuration

Nice to see that you solved your previous question yourself.
but I get this ERROR ERROR IPNDAgent: join failed on eth0; 99: setsockopt()
Depending on your ifconfig output, I assume that this issue has its roots in the fact that your interface eth0 does not have any IP address assigned. No IP address -> no bind possible.
One solution would be to use your bridge interface (br-lan) as DTN interface instead of eth0.
Kind regards, Johannes Morgenroth
Great! Thanks Johannes! After tuning some parameters it is working!
Resuming, to make it to work I initially used dtnd-safety-wrapper.sh (which is referring to the config file in /etc/config/ibrdtn) where I added config 'network' option type tcp option interface br-lan option port 4556 to generate ibrdtn.config in /tmp
However, the field net_interfaces = lan0 in ibrdtn.config is wrong and I fixed it manually to be "lan" I cannot spot which field as been set wrongly in /etc/config/ibrdtn Why is "net_interfaces" set to "lan0"?
thank you very much, Adriano

Hi again.
The "lan0" string is not wrong here. The real configuration of IBR-DTN works that it defines a set of convergence-layers by naming them. lan0 is the name in this case. Then it defines the parameters using net_<name>_... parameters. If you are using OpenWrt there exists an special way to configure the daemon using the UCI configuration file /etc/config/ibrdtn. Here you have to define a network and set the "option interface" to the interface you want to bind to.
Kind regards, Johannes Morgenroth
