Hint for Waldo

I am stuck. I am user n*****, and I found the SS* credentials of the user m****** but the problem is that I cannot login using those credentials (I tried using the famous metasploit module that helped me login to the user n***** as well). Probably the problem is that I don’t know something that I should. If someone could PM me and give me a hint (not a solution - spoiler) towards the correct direction, it would be great! Thank you!

EDIT: I just found my mistake, God, i am so stupid. You don’t need to login externally with ssh, but rather “internally” using a standard ssh command.
