NAD810 LAN Setup

End-node Host A / Host B / Host C

• Stop the dhclient
• 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: 10.0.0.254 / MAC1, MAC2

Task 0: collect the MAC addresses on all the machine

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)
