Fake NIC create

The fake-nic.sh script for creating the (additional) HostID if your laptop don’t have any wired Ethernet Adapter or many other cases :)

Russian description available here: https://idoka.ru/my-fpga-and-asic-scripts/#__ethX_c_MAC

Usage

1. Customize variable $DEV and $MAC in fake-nic.sh

2. Run it as root-user:

   ./fake-nic.sh

   that install required dependencies on your system and add NIC with proper $DEV (name) and $MAC (hostid)

Run on every bootup

The quick and dirty way to bring up fake NIC on every bootup is adding to your /etc/rc.local strings like this:

  MAC="E4:7D:DE:AD:BE:EF"
  DEV="eth1"
  ip tuntap add ${DEV} mode tap
  ifconfig ${DEV} hw ether ${MAC}
  ifconfig ${DEV} up

Limitation

This script works only on OS RHEL/CentOS 6.x/7.x as well. OS checker is built-in.

Explanation of working

see the source code fake-nic.sh

ToDo

• DEV and MAC pass as argv

• Create a systemd script executing for network activation
