Password required to ssh access from master node to node01

I was trying to do a practice lab, and it requires me to input password for node01…I am not sure if it is expected or not?
Please help.

Pratice lab:

terminal output:
root@controlplane:~# ssh node01
-bash: kubectl: command not found
root@node01:~# \

root@node01:~# ssh node01

Are you sure you want to continue connecting (yes/no)? yes

root@node01’s password:

@void , Could you please let us know the exact issue. From the last snippet, you are trying to ssh into node01 server to node01 server itself. I did not understand, why you are trying to do so. It would be better to elaborate with the lab name and a screenshot so that we can assist you in a better position.
