Super SSH (General Skills)
Using a Secure Shell (SSH) is going to be pretty important. Can you ssh as ctf-player to titan.picoctf.net at port 63238 to get the flag? You'll also need the password 6dd28e9b. If asked, accept the fingerprint with yes. If your device doesn't have a shell, you can use: https://webshell.picoctf.org If you're not sure what a shell is, check out our Primer: https://primer.picoctf.com/#_the_shell
