Password required to ssh access from master node to node01

Hi,
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:
[email protected]:~# ssh node01
-bash: kubectl: command not found
[email protected]:~# \

^C
[email protected]:~# ssh node01
The authenticity of host ‘node01 (10.35.39.3)’ can’t be established.
ECDSA key fingerprint is SHA256:u9OdNaCmrfntgjseysL28yF4sjvpXR6aev+/cLrHsvU.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘node01,10.35.39.3’ (ECDSA) to the list of known hosts.

@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.
