Playing with VirtualBox linked-clones

Have been experimenting with rapid deployment of cloned VMs and having some fun. Using VirtualBox's linked clone feature, I can create and start 30 instances to Kali Linux (30 being the number of classroom seats) in a matter of seconds. I've also worked out how to push new network configuration onto each instance. In-progress notes are on the TC4 internal Gitea server. Will also post 'em to Github when things are further along.

There's a bunch of other things to figure out and instantiate but they'll have to go on the "to do" list. Have signed up for my second season in the NCLs. Not sure if I'll be competing remotely (separate from the class), but I want to do better than last year. This means working through the harder parts of the gym, which opened a few days ago.

undefined reference to "show_hash"

Note to self: when compiling older software, the fix for the "undefined reference to 'show_hash'" error appears to be "apt-get install uthash-dev". That, or libhashkit-dev, but I believe that it's the uthash-dev library.
