Q: My VM doesn't power off when I run "shutdown now". Why?!
...
I'm not sure. What it does do is drop into single-user mode in console, giving you little control of anything if you're working via SSH. Use the following instead:

# shutdown -h now

Q: I'm being prompted for a password when logging into Team VM. Why isn't my pubkey working?
...
SSH tries to guess which pubkey to use, and occasionally gets it wrong. You can give it some hints by including the following in your ~/.ssh/config:
| Code Block |
|---|
Host teamX.ctf.csail.mit.edu
PubkeyAuthentication yes
IdentityFile ~/.ssh/<name_of_priv_key_file>
