I have already finished setting up eve-ng on ubuntu 16.04. I am running CISCO IOS with no errors. But when I tried with Juniper, Windows, Linux, ... it throw this error:

After that, I realized that this file (/sys/class/net/vnet0_1/bridge/group_fwd_mask) can not be edit. I tried bellow command:

Code: Select all

root@lab:~# echo 65535 > /sys/class/net/vnet0_1/bridge/group_fwd_mask
-bash: echo: write error: Invalid argument

How can I fix this?
Please help me!
Thanks in advance!
