Tilde Black's registration is a bit different from what you may

## Sending a request
Send an email to this system's admin user with an SSH public key that you will
use for authentication. The newer ed-25519 keys are recommended, but any valid
ssh key is acceptable. Some users enjoy using GPG keys for authentication using
the `--export-ssh-key` option.

## Receiving your invitation
Once your public key has been received, the admin will assign 10 random user
accounts to your control. You will receive an email response with the list of
user accounts you can now log into using your key.

Tilde Black has 10490 user accounts available, generated from 4 and 5 letter
word lists. By assigning you 10 random selections from already-created users we
hide your user creation date from others on the system and provide you a means
of anonymity to other users. You may use any or all of these user accounts.
They are all fully-featured.

## Logging in
It is recommended that users connect to ssh over tor to hide their IP address
from other users on the system. [instructions to follow] Once logged in, each
of your 10 user accounts will have an email waiting that includes that
account's password. Please change the password when you first log in by using
the passwd command. This password is not used for login authentication, but
will be necessesary for some operations like changing your shell (chsh).

## The basics
Your users have a `~/public_gopher` and `~/public_html` folder available. By
creating a root gophermap or index.html file in their respective folder you
will enable your gopher or website for that user. Your user will also appear on
the userlists for gopher or web within the next 12 hours.

## Detail Mode
### Overview
In order to ssh over tor, we'll need some way to make our terminal session or
a terminal command run over the tor network. My favorite way to do this is with
a program called `torsocks`. This utility pushes a single command or an entire
shell through a socks proxy to your tor connection. Since `torsocks` is just
a socks proxy that means we'll need to do a couple things to get it to work.

### Step 2: Configure tor
We need to configure our local tor differently than we did the server. We don't
need any hidden services this time, but we do need to allow local connections
to use it as a SOCKS proxy. Here's the key lines you'll need to uncomment,
change, or add:

That means you're up and running. Now in your other terminal window you can

This will respond back with: _"Tor mode activated. Every command will be
torified for this shell."_ And that's exactly it. You should be fully running
now and able to try your ssh connection.
