CC2531: 6lbr web interface not accessable. Seems to start correctly from logs

Gerald Brennan64
Prodigy 130 points

Part Number: CC2531

Following processors.wiki.ti.com/.../Cc26xx_sw_examples

Judging by the output of the 6lbr.log file I assume I should be able to access the 6lbr page, but I can't. I've followed the original demo and have made a few edits based on what I've read on this forum and others but cannot find the error.

Set up is BBB with cc2531 connected as slip radio

nothing is connected directly to the computer and the access point is ipv6 enabled

wrapsix running for NAT64

6lbr.conf:

    There's something wrong with latest 6lbr. You can go to /6lbr folder and run "git checkout ff69ae4214407eeec4c71f87589ac4bc7d3a8a49". You will get 6lbr version on 2016 Dec. 22th and you can rebuild 6lbr to test again.

    I've changed my version to the one you linked. Ran make all plugins tools in the 6lbr directory, and then sudo make install. I started everything up again and seem to have the same problem. 6lbr.log looks the same and I'm not able to connect to [bbbb::100] from any computer connected to the same access point

    According to your 6lbr.log, it works. Do you enable wrapsix on your 6lbr? If so, try not to run it and test again.

    I am enabling wrapsix. Unless that's getting stuck somewhere, it just says its starting then doesn't print anything else to the console.

    Try to disable it to test again. By the way, I know some anti-virus program would block IPv6 traffic so I suggest you to check your anti-virus program on you PC.

    I feel like the routing isn't happening. Shouldn't I see some reference to "bbbb::101" on the beaglebone side in ifconfig or netstat? or does that all get taken care of. I can't ping6 bbbb::100 from the beaglebone itself either

    I see no problem on all of the logs you provide. Do you check if you have anti-virus program blocking your IPv6 traffic?

    Disabling anti-vuris didn't help. I can use ipv6 normally when it is on as well:

    Question
    should the beaglebone be able to ping bbbb::100 itself?
  • 0 in reply to Gerald Brennan64
    Guru 735695 points
    I never try to ping bbbb::100 itself. I can try it when I can access to my 6lbr setup. If you ping bbbb::100 from your desktop, does it reply?
  • 0 in reply to YiKai Chen
    Prodigy 130 points
    Nope, bbbb::100 doesn't respond to ping form the pc. I don't think it have any knowledge of the bbbb/64 network. I feel like 6lbr has started correctly and is running, but idk if there is something wrong with the config of the beaglebone, or possibly even my router. There is a lot of conflicting info on whether wrapsix is needed and how that's configured as well. I feel like I'm so close, yet 1 magic command is missing from something

    I am not sure if this is related to Linux distribution version but I use bone-debian-7.8-lxde-4gb-armhf-2015-03-01-4gb when I test 6lbr on BBB. Maybe you can have a try.
