Hello, my name is David

Im having problems when trying to run the dtnd program on my computer. It used to work 3 months ago, but now it doesnt works. It gaves the following output on my computer(wlp4s0 is my wireless interface):

I guess the problems are related with multiples ipv6 addresses on the interface wlp4s0 (3 months ago I did not had multiple ipv6 addresses). My ifconfig output for the wlp4s0 interface:

script@script:~$ ifconfig wlp4s0 wlp4s0 Link encap:Ethernet Endereço de HW 68:14:01:a7:fd:5d inet end.: 192.168.0.16 Bcast:192.168.0.255 Masc:255.255.255.0 endereço inet6: 2804:14d:1494:8532:b569:2e86:3664:8ca5/64 Escopo:Global endereço inet6: fd11:2233:4455:1:f48d:2c3:b5d5:9607/64 Escopo:Global endereço inet6: fd11:2233:4455:1:e0bc:ac71:648e:651e/64 Escopo:Global endereço inet6: fe80::90a3:98d8:6edd:93dd/64 Escopo:Link endereço inet6: 2804:14d:1494:8532:f48d:2c3:b5d5:9607/64 Escopo:Global UP BROADCAST RUNNING MULTICAST MTU:1500 Métrica:1 pacotes RX:20694 erros:0 descartados:0 excesso:0 quadro:0 Pacotes TX:17267 erros:0 descartados:0 excesso:0 portadora:0 colisões:0 txqueuelen:1000 RX bytes:13073019 (13.0 MB) TX bytes:2696130 (2.6 MB)

------------------------------------------------------------------------------------- I have a raspberry pi zero W also running dtnd, but I dont have problems here. From the raspberry pi, I get the following output:

pi@raspberrypi:~ sudo dtnd -i wlan0 -c /home/pi/Documents/ibrdtn-conf/novoconfpizero.conf Sun Apr 15 21:58:09 2018 INFO NativeDaemon: IBR-DTN daemon 1.0.1 (build e7cfb5fc) Sun Apr 15 21:58:09 2018 INFO Configuration: Configuration: /home/pi/Documents/ibrdtn-conf/novoconfpizero.conf Sun Apr 15 21:58:09 2018 INFO NativeDaemon: use logfile for output: /var/log/ibrdtn/ibrdtn.log Sun Apr 15 21:58:09 2018 INFO BundleCore: Local node name: dtn://pizero.dtn Sun Apr 15 21:58:09 2018 INFO BundleCore: Forwarding of bundles enabled.

On the raspberry pi, I connected to the API and used the neighbor list command, got the following output (dtn://script.dtn is my computer):

neighbor list 200 NEIGHBOR LIST dtn://script.dtn

I tried the same approach on my computer, got the following output:

neighbor list 200 NEIGHBOR LIST

As you can see, it was expected to my raspberry (dtn://pizero.dtn) appears on the list, but it did not.

May you help me?
