# Multicast ## Steps * Step 1: **Manually** [[ https://ph.engr.unr.edu/w/ecc/cloning/ | clone ]] a machine in the lab. This will act as the server for the multicast. * Step 2: Netboot the entire lab * Step 3: Connect to **steamboat.engr.unr.edu** using your netid ```lang=bash # 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 ``` IMPORTANT: Check that all the hosts you want to clone have responded and no others. * Step 5: To check all hosts, run `ansible -i /etc/ansible/hosts -m "shell" -a "hostname" LAB_LETTER `. ```lang=bash # ansible -i /etc/ansible/hosts -m "shell" -a "hostname" lab_letter $ ansible -i /etc/ansible/hosts -m "shell" -a "hostname" lab_d ``` * Step 6: Using ansible, run the subscriber script ``` nohup sh /images/multi/udp-receiver-sda.sh & ``` * Step 7: Run the sender script on the machine acting as the server and hit key to start sending the script is located in /images/multi ``` sh udp-sender-sda.sh ``` * Step 8: Hit key on server to start sending data

# Multicast ## Steps * Step 1: **Manually** [[ https://ph.engr.unr.edu/w/ecc/cloning/ | clone ]] a machine in the lab.
