SSH into the server above with the provided credentials, and use the ‘-p xxxxxx’ to specify the port shown above. Once you login, try to find a way to move to ‘user2’, to get the flag in ‘/home/user2/flag.txt’.

Ive completed this task and got both of the flags. I was going over it again and when i try to connect im getting an error message “LOAD KEY id_rsa: invalid format” and a password prompt. Can anyone shed any light
