Notes

• The script only keeps track while it is running. As soon as you kill it, it loses all memory. You can re-run it, but it will only keep tracking since the start of the script.

• You can run it in the background by appending & to the end of the command like this:

  python3 node_height_checker_w_estimate.py &

  If you do this, it will run forever and print logs into the terminal seemingly from nowhere. You are not hacked. To kill the process, run:

  ps -ef | grep python

  You will see an output that looks like this:

  root         519       1  0 17:02 ?        00:00:00 /usr/bin/python3 /usr/bin/networkd-dispatcher --run-s
  root         610       1  0 17:02 ?        00:00:00 /usr/bin/python3 /usr/share/unattended-upgrades/unatt
  user        3222    2612  0 17:48 pts/1    00:00:00 python3 node_height_checker_w_estimate.py
  user        3631    2612  0 18:21 pts/1    00:00:00 grep --color=auto python
  

  You will see a process with the script name in it. Find the leftmost number in the same line (in this example, it is 3222). You need to kill this process:

  kill 3222
