how to open the web page in Smart-Bridge mode? #347

Closed steven3w closed 6 years ago

steven3w commented 7 years ago

Hi,

With CC1310 and beaglebone black, I have tried Raw, and bridge, they work well. Now I try smart-bridge, I can ping the sensor in the host, but I can not open the web page.

The 6lbr.conf: /etc/6lbr/6lbr.conf

MODE=ROUTER

MODE=SMART-BRIDGE

RAW_ETH=0 BRIDGE=0 CREATE_BRIDGE=0 DEV_BRIDGE=br0 DEV_TAP=tap0 DEV_ETH=eth0 RAW_ETH_FCS=0 DEV_RADIO=/dev/ttyUSB0 BAUDRATE=115200

Enable this line if radio device is not detected

SCAN_DEVICE=/usr/lib/6lbr/bb-scan-usb.sh

LOG_LEVEL=3 #INFO and above only

The 60dev file is as follow:

#!/bin/bash
#ifup eth0
ip -6 address add fd00::2/64 dev tap0
sysctl -w net.ipv4.conf.all.forwarding=1
sysctl -w net.ipv6.conf.all.forwarding=1

the /var/log/6lbr.ip
fd00::100

with the above settings, and a sensor with ipv6=fd00::212:4b00:a27:c794, I can ping it successfully in the host.

My question is how to open the web page in Smart-bridge mode?

The reason I have to use the smart-bridge is that in the https://github.com/cetic/6lbr/wiki/6LBR-Interface-Configuration, it said that

Important note: Your Ethernet driver must support Promiscuous mode! If not the bridge won't work properly and you will have intermittent connectivity with 6LBR. The Ethernet driver of the Beaglebone does not support promiscuous mode!

Best regards

You are confusing the configuration of the 6LBR interface and the operational mode. SmartBridge mode is not related at all with the bridge configuration of the 6LBR tap interface.

The bridge configuration of the interface means the tap interface of 6LBR is bridged with the Ethernet interface of your host.

SmartBridge oeprational mode means that the WSN network is in the same subnet as your Ethernet segment.
