# Multicast ## Steps * Step 1: Manually Clone a machine in the lab this will act as the server in the multicast * Step 1.1: dd the mbr to /tmp/mbr.bin ``` dd if=/dev/sda of=/tmp/mbr.bin bs=512 count=1 ``` * Step 2: Netboot the entire lab * Step 3: Connect to **steamboat.engr.unr.edu** using you netid * Step 4: On **steamboat** use ansible to connect to all of them ``` cd /srv/ansible/ source python_env/bin/activate ansible -i /etc/hosts -m shell -a "hostname" ``` * Step 4.1: Check that all the hosts you want clone responded and no others. **VERY IMPORTANT!!** * Step 5: using ansible run subscriber script ``` nohup sh udp-receiver-sda.sh & ``` * Step 6: Run the sender script on the machine acting as the server and hit key to start sending ``` sh udp-sender-sda.sh ``` * Step 7: Hit key on server to start sending data
