Use OpenStack CDCI template to start a new VM. To access the VM, login to fep.grid.pub.ro using your UPB credentials, and from there ssh into the private IP from OpenStack using “ubuntu” as a username and your ssh key.

Due to the fact that we have to work remote, please make sure that you record your screen while working. Here is how.

# start the recording after you ssh into the machine
ubuntu@cdci-v2:~/$ asciinema rec lab03_mihai.cast
[...]
# !!!IMPORTANT before you start working echo your name in the terminal!!!
ubuntu@cdci-v2:~/$ echo "Mihai Chiroiu's terminal!"
# ============ IMPORTANT ============
# do the tasks: enter docker
ubuntu@cdci-v2:~/$ ./attacker_bash.sh 
root@attacker:/# pwd
/
root@attacker:/# 
root@attacker:/# exit
# exited docker
# stop recording 
ubuntu@cdci-v2:~/cdci/labs/lab03$ exit
asciinema: recording finished
asciinema: press <enter> to upload to asciicinema.cdci.ro, <ctrl-c> to save locally

View the recording at:

    http://asciinema.cs.pub.ro/a/QJdizlwTeMTSivCJd1M1VLx6l

# the IP of server has changed, sorry
ubuntu@cdci-v2:~/cdci/labs/lab03$ sudo echo "35.246.203.175 asciinema.cs.pub.ro" > /etc/hosts
# upload the recording
ubuntu@cdci-v2:~/cdci/labs/lab03$ asciinema upload lab03_mihai.cast

When you finish your work, submit the details on the form . Double check to see if all is good (https://docs.google.com/spreadsheets/d/1_2uiVTnEv5RRbnp7lrw3EPqfBiN7JH1s8EQ6ru3Hhb4/edit?usp=sharing)
