I've just created a ubuntu 16.10 machine and tried to create a vcan network:

sudo ip link add dev vcan0 type vcan

As soon as I enter this though I lose my internet connection.

ping www.google.com

Never returns. I'm not even bringing the vcan0 interface up. Just loading the standard vcan module Any thoughts where to even start to debug?

  • More information. My network is as such CableModem(10.0.0.1)-->Router(192.168.1.1)-->Ubuntu Computer(192.168.1.167). After I add the vcan device I can still ping the router and other computers (laptop) on the 192.168.1.x network. Just can't get through to the internet, or perhaps the return route can't get back? – jbholtz Nov 04 '16 at 19:44
  • If I sudo add....sudo del....sudo add...sudo del....Then my network seems to be okay. Not sure what is going on – jbholtz Nov 08 '16 at 13:46
