Connecting coprocessor to bridge to communicate with internet

Eric_B_2 · ‎04-21-2015

Hello,

I am running Ubuntu 14.04 with a xeon phi 31s1p and I have been trying to set up a bridge so that I can have the phi access the internet, although I have been having a lot of trouble and can't seem to figure out what's wrong. I'm pretty sure the bridge itself is fine but the phi can't connect to it, anytime I try and use the simple command for it to connect to the bridge it gives this:

/var/mpss/mic0/etc/network# micctrl --network=static --bridge=br0 --ip=172.31.1.1
[Error] br0: Failed - required brctl command not installed

But it is installed...some mess with the mpss tooling.

The output of ifconfig is the following:
