End-node Host A / Host B / Host C

  • Stop the dhclient and/or NetworkManager
  • Host A: IP 10.0.0.1 / MAC xx:xx:xx:xx
  • Host B: 10.0.0.2 / MAC
  • Host C: 10.0.0.3 / MAC

Gateway

  • Stop the NetworkManager
  • Run dhclient on the external interface
  • Assign 10.0.0.254 to the internal interface

Task 0: collect the MAC addresses on all the machines

Task 1: To find out which network interface on the gateway is connected to the LAN

  • boot up and configure end-nodes
  • nics=$(/sbin/ifconfig -a | grep eth | awk '{print $1}')
  • assign 10.0.0.254 to the first device
  • ping host A or host B, or host C
  • check for result
  • assgin 10.0.0.254 to the second device if the first one failed

Here's a skeleton of a script to start us off. I'm missing most of the syntax and it has lots of pseudo-code, but the idea is there - scarter4:

  #!/bin/bash
  
  ## Stop the dhcpclient
  service stop dhcpclient
  ## Grab a list of eth devices
  nics=$(/sbin/ifconfig -a | grep eth | awk '{print $1}'
  ## Assign IP to each device w. loop
       ## start loop
       ifconfig $nic 10.0.0.254 netmask 255.0.0.0
       ## Ping, did it work?
       ping -c 1 10.0.0.1
       if (echo $?)
       then
               break
       else
               null
       ## close loop here
  ## grab a list of MAC addesses
  ifconfig -a | grep HWaddr | awk '{print $5}'


Task 2: Configure route(s)
