can not access [bbbb::100] on ubuntu 12.04 or 18.04 #385

desword · 2018-10-25T12:04:14Z

I tried to install the 6lbr on a computer with ubuntu 12.04 (instant contiki 3.0) or 18.04.
I strictly follow the steps on the http://morschi.com/2017/03/28/setting-up-a-6lowpan-border-router-6lbr-using-a-vm-and-slip-radio/, however, I only get the following results:

The 6lbr service can not start on ubuntu 12.04 (instant contiki 3.0) when I typing sudo service 6lbr start, and using the command service --status-all to check. I only get

[-] 6lbr.

The 6lbr service may be started on ubuntu 18.04, the results of service --status-all change to [+] 6lbr. However, I can not access [bbbb::100]. Meanwhile, there are no logs at /var/log/6lbr.log, and there is also no file created at /etc/6lbr/nvm.dat.

On ubuntu 12.04, I have enabled the ipv6 access on firefox browser. and on ubuntu 18.04, I used the chrome which enables the ipv6 automatically.

I only want to setup the 6lbr service on a computer. The slip-radio and other node application have not compiled or tested yet. But I think the latter node application will have no influences on the installation of 6lbr.

Anyone can tell me how to fix this problem? Thanks very much.

The 6lbr is the latest.

I have also tried on Debian 8.x, However, it doesn't work.

This the 6lbr service status on ubuntu 18.04 computer:

However, when I use chrome to access [bbbb::100], it replys with

This site can’t be reached  
http://[bbbb::100]/ is unreachable.  
ERR_ADDRESS_UNREACHABLE

Without a slip-radio connected, 6LBR won't start up. Though you should have a 6lbr.log file with a repeating line saying that it waits for the slip-radio. As yo don't have a 6lbr.log file, this means that you also did not configure /etc/6lbr/6lbr.conf and so even the service startup code can't work.

6LBR is known to work on Ubuntu 14, 16, and 18, though on 18 netstat and ifconfig have been removed so you need a patch that is available in the develop branch.

Now, I have tried to setup the 6lbr on Raspberry 2 B model v1.1.
The final result is that I still can no access the [bbbb::100], but there are 6lbr.log in /var/log/.

I also compile the slip-radio from the contiki/examples/ipv6/slip-radio on CC2650 launchpad using the following command.

cd $CONTIKI_HOME/examples/ipv6/slip-radio
make TARGET=srf06-cc26xx BOARD=launchpad/cc2650 slip-radio.bin

Then I download the slip-radio.bin to the CC2650 launchpad using TI Flash programmer. And I connect it to the Raspberry 2 via /dev/ttyACM0, which I have set in the /etc/6lbr/6lbr.conf

The address bbbb::100 seems setup successfully, However, I still can not access the http://[bbbb::100] on raspberry 2.

for now, I can access [bbbb::100] on windows, which is another computer with the same network address duration.
By setting the following ipv6 address.

ipv6 address: bbbb::101
netmask: 64
ipv6 gateway: bbbb::100

I can not set the ipv6 address successfully, so I have switched to the windows and it works at least I can see the 6lbr configuration web site.

Hi, I also have the same kind of problem. 6lbr log shows it runs finely but I cannot access the webpage through the PC. Could you please share how did u resolve it?

desword · 2019-01-06T02:52:56Z

I access the website on windows. And set the Ipv6 address on windows.

udpasan · 2019-01-06T04:03:18Z

@desword thanks for the reply. I tried with my laptops in windows as you put in the above comment. But it did not work. Also tried with ubuntu and fedora by making bootable usb sticks but still it did not work. Since Im using raw ethernet mode, I did not make the br0 interface. Is it mandatory ?

desword · 2019-01-06T07:00:22Z

Maybe you should first check whether the global address is assigned. By the way, you run the 6lbr on Raspberry or on PC?
You may ref to https://desword.github.io/2018/11/03/cc2650-mqtt-client-example/
But I am sorry that it is the only chinese version.

udpasan · 2019-01-06T08:14:40Z

I run 6lbr in the raspberry pi. Did you do it in your PC?

chenek · 2019-01-06T12:26:58Z

@udpasan try “git checkout ff69ae4” on 6lbr to test again.

Followed your step after installing 6lbr....and i perfectly access the webpage from windows....thnx for your help
