Steps

Step 1: Manually clone a machine in the lab. This will act as the master.
Step 2: Netboot the entire lab
Step 3: Connect to steamboat.engr.unr.edu using your netid

# ssh netID@steamboat.engr.unr.edu
$ ssh igrant@steamboat.engr.unr.edu

Step 4: On steamboat, source into your environment to use ansible.

$ source /srv/ansible/python_env/bin/activate

Step 5: To check all hosts, run ansible -i /etc/ansible/hosts -m "shell" -a "hostname" LAB_LETTER .

# ansible -i /etc/ansible/hosts -m "shell" -a "hostname" lab_letter 
$ ansible -i /etc/ansible/hosts -m "shell" -a "hostname" lab_d

Step 6: On your steamboat connecting while using ansible, run the subscriber script nohup sh /netboot/images/multi/udp-receiver-sda.sh &

# ansible -i /etc/ansible/hosts -m "shell" -a "nohup sh /netboot/images/multi/udp-receiver-sda.sh &" lab_x
$ ansible -i /etc/ansible/hosts -m "shell" -a "nohup sh /netboot/images/multi/udp-receiver-sda.sh &" lab_c

Step 7: Run the sender script on the master and hit key to start sending the script is located in /netboot/images/multi

$ cd /netboot/images/multi
$ sh udp-sender-sda.sh

Step 8: Hit the ANY key on server to start sending data.
Step 9: Be sure to go around and join the computers to the domain and activate labview.

[WIP]

Step 9: When done, be sure to rename the machine, join to the domain, and activate labview by connecting to tinkerbell using the identity file.

# make sure that you are still on steamboat
$ sudo ssh root@tinkerbell.engr.unr.edu -i /srv/ansible/.ssh/coen-ansible

Step 10: Source into the IMM Environment

$  source /opt/imm-env/bin/activate

Step 11: Head over to /opt/imm

$ cd /opt/imm

Step 12: Here, you should see the winrm_tasks.py file. This will help you do all that you need.
To execute, run ./winrm_tasks.py --filter ECC-LAB- TASKS.
