I apologize if this is a FAQ, I'm searching through the mail archives now, too, but so far I haven't found a solution to my problem.

I'm trying to bring up 6lbr on my BeagleBone Black with a TI CC2531EMK. I've flashed the slip radio firmware on it as described here then started working through the howto described here with no success.

So now I've taken a step back and all I want to see first is the interface come up in some expected configuration such that I might be able to ping a remote 6lowPAN device.

My BBB is currently running the 2016-01-24 image of Debian Jessie from BeagleBoard.org (I changed the default /bin/sh->bash from dash because dash would throw errors on <6lbr-functions> when it was sourced) and I've cloned 6lbr and built it directly on the board with the following steps:

cd 6lbr/examples/6lbr
make TARGET=native all plugins tools
suod make install

Then I copied the <6lbr.conf.beaglebone> to </etc/6lbr/6lbr> and changed <DEV_RADIO=/dev/ttyUSB0> to <DEV_RADIO=/dev/ttyACM0> since that's how my 2531 appears on the system. And I bumped up the verbosity of the debug messages hoping it'd help me figure out what was going wrong. So my config file looks like this:

root@beaglebone:~# cat /etc/6lbr/6lbr.conf
#This file contains a default configuration for BeagleBone platform using
#a Telos SLIP Radio
#The full list of parameters and their meaning can be found in 6lbr.conf.example

MODE=ROUTER
#MODE=SMART-BRIDGE
#MODE=RPL-RELAY
#MODE=FULL-TRANSPARENT-BRIDGE
#MODE=NDP-ROUTER
#MODE=6LR
#MODE=RPL-ROOT

RAW_ETH=0
BRIDGE=1
DEV_BRIDGE=br0
DEV_TAP=tap0
DEV_ETH=eth0
RAW_ETH_FCS=1

DEV_RADIO=/dev/ttyACM0
BAUDRATE=115200

#Enable this line if radio device is not detected
#SCAN_DEVICE=/usr/lib/6lbr/bb-scan-usb.sh

LOG_LEVEL=4 #INFO and above only

Then I ensured I had my system configured to accept RA messages as described here and enabled forwarding for both IPv4 and IPv6:

root@beaglebone:~# sysctl net.ipv6.conf.eth0 | grep accept_ra
net.ipv6.conf.eth0.accept_ra = 1
net.ipv6.conf.eth0.accept_ra_defrtr = 1
net.ipv6.conf.eth0.accept_ra_from_local = 0
net.ipv6.conf.eth0.accept_ra_mtu = 1
net.ipv6.conf.eth0.accept_ra_pinfo = 1
net.ipv6.conf.eth0.accept_ra_rt_info_max_plen = 64
net.ipv6.conf.eth0.accept_ra_rtr_pref = 1
sysctl: reading key "net.ipv6.conf.eth0.stable_secret"
root@beaglebone:~# sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1
root@beaglebone:~# sysctl net.ipv6.conf.all.forwarding
net.ipv6.conf.all.forwarding = 1
root@beaglebone:~#

Then I started 6lbr:

And at no point do my interfaces ever get a aaaa:: or bbbb:: configuration, I never see an ipv6 route and nothing seems to happen.

So the tentative addresses look sane, but it never goes any further than that.

Since I've done a fair bit of digging around to try to debug this myself, I thought I should also include some more detail in case I've broken something else while I was looking around for a solution.

Any idea what I'm missing or doing wrong here?

laurentderu commented 8 years ago

At first sight everything looks good, except that you have enabled accept_ra and accept_ra_rt_info_max_plen on eth0 and not br0 As eth0 is part of a bridge, it's IP stack is disabled. You have to use br0 instead.

sysctl -w net.ipv6.conf.br0.accept_ra=1
sysctl -w net.ipv6.conf.br0.accept_ra_rt_info_max_plen=64

If that does not solve your problem, maybe you have a network manager, like wicd or NetworkManager that override your configuration.

That's a very good point, I realized after I read your comment that the Debian image runs connman by default and thought it might be getting in the way. First I went back and disabled it with service connman disable and that didn't seem to help, so I swapped out my whole image in favour of the Debian console image from http://elinux.org/Beagleboard:BeagleBoneBlack_Debian. I corrected the /bin/sh link again then grabbed the 1.3.3 6lbr release from https://github.com/cetic/6lbr/wiki/Releases and installed the .deb rather than going through the build process again. The console image is very limited. I had to install bridge-utils but after that 6lbr seemed happy enough to start.

I'm still not seeing any routes set up and the configuration applied.

Just to re-cap what I've done since re-imaging my SD card:

root@beaglebone:~# cat /etc/6lbr/6lbr.conf
#This file contains a default configuration for BeagleBone platform using
#a Telos SLIP Radio
#The full list of parameters and their meaning can be found in 6lbr.conf.example

BAUDRATE=115200

#Enable this line if radio device is not detected
#SCAN_DEVICE=/usr/lib/6lbr/bb-scan-usb.sh

LOG_LEVEL=4 #INFO and above only

Which is the 6lbr.conf.beaglebone file tweaked with a higher log-level and DEV_RADIO pointing at ttyACM0 rather than ttyUSB0 since that's where my device appears.

root@beaglebone:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface

# Note on some boards, usb0 is automaticly setup with an init script
iface usb0 inet static
    address 192.168.7.2
    netmask 255.255.255.0
    network 192.168.7.0
    gateway 192.168.7.1

Which I took wholesale from /etc/6lbr/interfaces.beaglebone.example because it looked like a reasonable drop-in replacement for the /etc/network/interfaces on my image.

Then I set this:

root@beaglebone:~# tail -15 /etc/sysctl.conf 
#net.ipv4.conf.all.accept_source_route = 0
#net.ipv6.conf.all.accept_source_route = 0
#
# Log Martian Packets
#net.ipv4.conf.all.log_martians = 1
#
net.ipv6.conf.all.accept_ra = 1
net.ipv6.conf.all.accept_ra_defrtr = 1
net.ipv6.conf.all.accept_ra_from_local = 0
net.ipv6.conf.all.accept_ra_mtu = 1
net.ipv6.conf.all.accept_ra_pinfo = 1
net.ipv6.conf.all.accept_ra_rt_info_max_plen = 64
net.ipv6.conf.all.accept_ra_rtr_pref = 1
net.ipv4.ip_forward = 1
net.ipv6.conf.all.forwarding = 1

Because I'm a big fan of using syslog.conf. Unfortunately that still doesn't work for net.ipv6.conf.br0.accept_ra and ...accept_ra_rt_info_max_plen as I'd hoped, so I added this to 50bridge:

root@beaglebone:~# grep jjm -n -C3 /etc/6lbr/ifup.d/50bridge

Which now seems to ensure that when the bridge comes up the sysctl settings are as expected. But even so I'm still not getting any routes created and my interfaces are not getting assigned addresses as I thought I should see:

Obviously I've cycled my logs on my system while debugging so we're only looking at the latest run of logs above. Is there something else I could provide or look at that might help me understand what's going on here?

Right now I'm having my BBB build master from git to see if that helps, but that's kind of a lengthy process, as you probably know. :-)

Somewhat related, in the future if I'm providing longer blocks of information like this, would it be better for me to put it all in a gist and link to it from the comments or dump the info right in the comments? Different projects / maintainers / devs have different preferences and I want to stick to whatever is easiest.

laurentderu commented 8 years ago

Thanks to you extensive blocks of information ;) I think I know the root cause of your problem :

net.ipv6.conf.all.forwarding = 1

This setup configure your system as an IP Router, and, by definition a router never listen to RA messages. So, the RA sent by 6LBR is ignored by the beaglebone. You can either reverse it to 0 or use a magic mode provided by the linux kernel :

net.ipv6.conf.br0.accept_ra=2

With this value, the system will behave as a router, but your interface will still listen to RA and use them for the address autoconfiguration

jjmcdn commented 8 years ago

Awesome, that was it. I set net.ipv6.conf.br0.accept_ra=2 and now:

Hi All,

We are working on BBB using 04.00.00.04 TI SDK (arago on linux) , After using this command "make TARGET=native all plugins tools" we are getting these errors :+1: make TARGET=native all plugins tools
rm -rf bin mkdir -p bin make TARGET=native clean make[1]: Entering directory '/etc/6lbr/examples/6lbr' rm -f ~ core core .srec \ .lst .map \ .cprg .bin .data contiki.a .firmware core-labels.S .ihex .ini \ .ce .co rm -rf .so obj_native/.so rm -rf obj_native make[1]: Leaving directory '/etc/6lbr/examples/6lbr' make TARGET=native bin/cetic_6lbr_smart_bridge make[1]: Entering directory '/etc/6lbr/examples/6lbr' make TARGET=native CETIC_6LBR_SMARTBRIDGE=1 WITH_UDPCLIENT=0 make[2]: Entering directory '/etc/6lbr/examples/6lbr' make[2]: Nothing to be done for 'cetic-6lbr'. make[2]: Leaving directory '/etc/6lbr/examples/6lbr' mkdir -p bin mv cetic-6lbr.native bin/cetic_6lbr_smart_bridge mv: can't rename 'cetic-6lbr.native': No such file or directory make[1]: [platform/native/Makefile.native:40: bin/cetic_6lbr_smart_bridge] E1 make[1]: Leaving directory '/etc/6lbr/examples/6lbr' make: [platform/native/Makefile.native:76: all] Error 2

So please give any solutions for this,
