Unabe to use Wrapsix with 6lbr on raspberrypi #86

Closed deepikay closed 8 years ago

Hi laurentderu,

I am trying to upload z1 data to ubidots.com by following this link :

https://github.com/marcozennaro/IPv6-WSN-book/blob/master/5.asc

I installed 6lbr on raspberrypi, connected it with a slip-radio loaded z1 mote and, To use NAT64 with Wrapsix then I installed wrapsix on raspberry, modifed wrapper.c with necessary configuration:

when I start wrapsix as daemon I get :

[1] 3039 [Info] WrapSix 0.2.0 is starting pi@raspberrypi ~/wrapsix-0.2.0/src $ [Error] Unable to create listening socket

sudo service 6lbr restart

Logs:

In my browser I able to see border router page : [bbbb::100]

After this when I run ubidots_demo.c on another z1 mote I get following logs:

Any suggestions would be helpful

Thanks!!

I never used wrapsix, but I guess the problem is coming from : 

 [1] 3039
[Info] WrapSix 0.2.0 is starting
pi@raspberrypi ~/wrapsix-0.2.0/src $ [Error] Unable to create listening socket

Without a listening socket, you can not have NAT64 and connectivity.

Also, what could be missing is the configuration of the default router on 6LBR, without that, it can not route the 64:ff9b:: traffic towards WrapSix

deepikay commented 9 years ago

Raspberry pi is connected to a router by ethernet cable and my laptop also connected to router through ethernet

My 6lbr.conf is like this :

MODE=ROUTER RAW_ETH=1 BRIDGE=0 DEV_BRIDGE=br0 DEV_TAP=tap0 DEV_ETH=eth0 RAW_ETH_FCS=0 DEV_RADIO=/dev/ttyUSB0 BAUDRATE=115200 LOG_LEVEL=3 #INFO and above only

My wrapper.c looks like :

define INTERFACE "eth0"

define PREFIX "64:ff9b::"

define IPV4_ADDR " x.x.x.x" //unused ip in my network

define HOST_IPV6_ADDR "bbbb::101"

define HOST_IPV4_ADDR "x.x.x.x"// ip address of raspberry pi as mentioned in ifcocnfig

Where do I need to add default router?

laurentderu commented 9 years ago

You can add the default route in the configuration page of 6LBR (http://[bbbb::100]/config.html), but first check if WrapSix is correctly started

weijian19391 commented 9 years ago

@deepikay in case your issue isn't solve, u can do the following to start wrapsix: sudo wrapsix

@laurentderu what is the default route that we should set? and what do u mean by routing traffic towards wrapsix?

laurentderu commented 9 years ago

@weijian19391 I never used wraps, so it's only a guess, I think you have to tell 6lbr where to send the data for wrapsix and so define a route towards its endpoint. But maybe wrapsix simply sniff the traffic and you don't need that route :)
