Hi,
I am experiencing an issue while performing this lab. It is asking for a password to access the app01 server and other servers, but the server passwords have not been provided in the lab instructions.
Could you please help me with this issue? If you know the passwords, kindly share them so I can proceed with the lab.
We have four app server from app01 to app04. You can access each app from jump host using command ssh app01 and similarly for other apps. Assign new IPs to each host as per details given below:
a. Assign 172.16.238.15/24 ip address to app01
b. Assign 172.16.238.16/24 ip address to app02
c. Assign 172.16.239.15/24 ip address to app03
d. Assign 172.16.239.16/24 ip address to app04
e. We also need to remove existing IPs from these apps after assigning them new IPs but do not remove them right now as it can break your connection, if you are sure you are done with required changes just click on Check button below, it will do the rest.
In this lab, we install the public ssh key for the jumphost on app01 and its friends, as so:
thor@jumphost ~$ ls -a ~/.ssh
. .. id_rsa id_rsa.pub
thor@jumphost ~$ cat ~/.ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDFpUwGN8rN9W4ps01Jxfw/yNjEMOOLw/TGa1uzfpM7ukk8SePN5Hnp5+2UY5XlFVBhz7HNqvhQ42B/wNZxQvUvqEtYZQ7vkyYvwTfiySB4vKXCGt0HnstzxHvIQ/35DTvkxBogKJrx873Si28XaLKPT2swJFk5Mf5CuGxXiggDIInS3FsWTK0x3HS/zq5isWv0U/trYU7aW35uGFTnLrBuOquRjpFpwkB/yPbxAUrrE9kqodd8KkaoWUW0pWy0TlxX26WtVeYOrDi0nKQxkwaoh7X9fv0y1tooTmmHjchKbrpotRGuIrfzWpbr+BAaEprfaQKFu0mlMTOur3XV+PKf
thor@jumphost ~$ ssh app01
The authenticity of host 'app01 (172.16.238.11)' can't be established.

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

So you can only log in w/o a password if go from thor@jumphost to the other hosts. Otherwise, you need a password. Since we don’t supply you those, you need to go back to jumphost to log into the other hosts.
