## tilde.club details
|
||||
|
||||
for example, to connect to tilde.club, you can do:
|
||||
|
||||
```
|
||||
ssh user@tilde.club
|
||||
mosh user@tilde.club
|
||||
```
|
||||

||||

|
||||
|
||||
## intro
|
||||
|
||||
** if you just want to get right to a tutorial you can
|
||||
[skip over this background info](#how-to-make-an-ssh-key)**
|
||||
|
||||
while [tilde.club](https://tilde.club) is accessible on the web and features
|
||||
lovely web pages written by its users, most interaction with tilde.club takes
|
||||
place **inside the machine** that runs tilde.club as opposed to via web forms
|
||||
that have an effect from **outside** tilde.club's computer.
|
||||
|
||||
this is what sets tilde.club apart from most other online communities. you
|
||||
connect directly to another computer from yours alongside other people and then
|
||||
write your web pages, chat, and play games all via text-based interfaces right
|
||||
on tilde.club's computer.
|
||||
|
||||
prior to the web (which debuted in 1995) this is how pretty much all computer
|
||||
stuff got done. you connected directly to a machine (usually over a direct,
|
||||
physical phone line) and did your work there.
|
||||
|
||||
for a long time, people used a tool called
|
||||
[`telnet`](https://en.wikipedia.org/wiki/telnet) to connect to other computers.
|
||||
these days we use a tool called **ssh**.
|
||||
|
||||
`ssh` is a text-based tool that provides a direct connection from your computer
|
||||
to another. ssh is an acronym that stands for secure shell. the _shell_ part
|
||||
refers to the fact that it's a text-based tool; we use the word shell to refer
|
||||
to a text-based interface that you give commands to. the _secure_ part refers
|
||||
to the fact that, when you're using ssh, no one can spy on your connection to
|
||||
another computer (unlike the old `telnet` command).
|
||||
|
||||
**why bother with all of this?** passwords are really insecure and hard to manage.
|
||||
using keys makes life easier for you, fair user (your account is less likely to
|
||||
be hacked) and for me, your humble sysadmin (less administration than passwords).
|
||||
|
||||

|
||||
|
||||
## how to make an ssh key
|
||||
|
||||
SSH supports a handful of types of cryptographic keys. The most used are [RSA](
|
||||
<https://en.wikipedia.org/wiki/RSA_(cryptosystem)>) and the more modern [Ed25519](
|
||||
https://en.wikipedia.org/wiki/EdDSA#Ed25519).
|
||||
|
||||
RSA is the de-facto standard and is supported everywhere (just choose a big
|
||||
enough key like 4096 bits to be secure). Ed25519 is designed to be faster and
|
||||
smaller withouth sacrificing security, so is best suited for embedded devices
|
||||
or machines with low resources. It's supported on tilde (and really on any
|
||||
modern system) but you may find older systems which do not support it.
|
||||
|
||||
Below you'll find instructions to generate either type (or both if you want).
|
||||
|
||||
Keep in mind that these instructions leave your private keys unencrypted in
|
||||
your local hard disk. So keep them private; never share them. A good solution
|
||||
is to provide a password for them at creation time, but this implies entering
|
||||
a password any time you used them (impractical) or use something like [ssh-agent](
|
||||
https://man.openbsd.org/ssh-agent.1) (a bit more complex)
|
||||
|
||||
pick your fighter: [[mac](#mac)] | [[windows](#windows)] | [[linux](#linux)]
|
||||

||||

#### generating your keypair
|
||||
|
||||
1. open terminal (it's in `/Applications/Utilities`)
|
||||
|
||||
1. create your .ssh directory:
|
||||
|
||||
```bash
|
||||
mkdir -m 700 ~/.ssh
|
||||
```
|
||||
|
||||
1. create your keys:
|
||||
|
||||
for rsa keys:
|
||||
|
||||
```bash
|
||||
ssh-keygen -t rsa -b 4096
|
||||
```
|
||||
|
||||
for dd25519 keys:
|
||||
|
||||
```bash
|
||||
ssh-keygen -t ed25519 -a 100
|
||||
```
|
||||
|
||||
1. if you press enter to accept the defaults, your public and private key will
|
||||
be located at `~/.ssh/id_rsa.pub` and `~/.ssh/id_rsa` respectively (or
|
||||
`~/.ssh/id_ed25519.pub` and `~/.ssh/id_ed25519` if you chose ed25519 type)
|
||||
|
||||
1. `cat ~/.ssh/id_rsa.pub` (or `cat ~/.ssh/id_ed25519.pub` for ed25519)
|
||||
|
||||
1. copy the output of the last command and paste it in the sshkey field on the
|
||||
signup form (or email it to [~root](mailto:root@tilde.club) if you already have an account)
|
||||
|
||||
#### using your keypair
|
||||
|
||||
once an admin approves your signup, you can join the tilde.club
|
||||
|
||||
1. open terminal (it's in `/Applications/Utilities`)
|
||||
|
||||
1. `ssh` to tilde.club:
|
||||
|
||||
```bash
|
||||
ssh username@tilde.club
|

### windows
|
||||
|
||||
there are a couple options for using ssh on windows these days.
|
||||
i like to use [git bash](https://git-scm.com).
|
||||
|
||||
#### generating your keypair
|
||||
|
||||
choose from any of the following options:
|
||||
|
||||
- [windows subsystem for linux](https://docs.microsoft.com/en-us/windows/wsl/install-win10)
|
||||
- [msys2](http://www.msys2.org/)
|
||||
- [git bash](https://git-scm.com)
|
||||
|
||||
1. open your new shell
|
||||
|
||||
1. create your .ssh directory
|
||||
|
||||
```bash
|
||||
mkdir .ssh
|
||||
```
|
||||
|
||||
1. create your keypair
|
||||
|
||||
for rsa keys:
|
||||
|
||||
```bash
|
||||
ssh-keygen -t rsa -b 4096
|
||||
```
|
||||
|
||||
for ed25519 keys:
|
||||
|
||||
```bash
|
||||
ssh-keygen -t ed25519 -a 100
|
||||
```
|
||||
|
||||
1. if you press enter to accept the defaults, your public and private key will
|
||||
be located at `~/.ssh/id_rsa.pub` and `~/.ssh/id_rsa` respectively (or
|
||||
`~/.ssh/id_ed25519.pub` and `~/.ssh/id_ed25519` if you chose ed25519 type)
|
||||
|
||||
1. `cat ~/.ssh/id_rsa.pub` (or `cat ~/.ssh/id_ed25519.pub` for ed25519)
|
||||
|
||||
1. copy the output of the last command and paste it in the sshkey field on the
|
||||
signup form (or email it to [~root](mailto:root@tilde.club) if you already have an account)
|
||||
|
||||

1. `ssh` to tilde.club:
|
||||
|
||||
```bash
|
||||
ssh username@tilde.club
|
||||
```
|
||||
|

### linux
|
||||
|
||||
there are a lot of linux distros, but `ssh` and `ssh-keygen` should be available
|
||||
in almost all cases. if they're not, look up how to install ssh for your distro.
|
||||
|
||||
#### generating your keypair
|
||||
|
||||
1. make sure you have a `~/.ssh` directory
|
||||
|
||||
```bash
|
||||
mkdir -m 700 ~/.ssh
|
||||
```
|
||||
|
||||
1. create your keys
|
||||
|
||||
for rsa keys:
|
||||
|
||||
```bash
|
||||
ssh-keygen -t rsa -b 4096
|
||||
```
|
||||
|
||||
for ed25519 keys:
|
||||
|
||||
```bash
|
||||
ssh-keygen -t ed25519 -a 100
|
||||
```
|
||||
|
||||
1. if you press enter to accept the defaults, your public and private key will
|
||||
be located at `~/.ssh/id_rsa.pub` and `~/.ssh/id_rsa` respectively (or
|
||||
`~/.ssh/id_ed25519.pub` and `~/.ssh/id_ed25519` if you chose ed25519 type)
|
||||
|
||||
1. `cat ~/.ssh/id_rsa.pub` (or `cat ~/.ssh/id_ed25519.pub` for ed25519)
|
||||
|
||||
1. copy the output of the last command and paste it in the sshkey field on the
|
||||
signup form (or email it to [root@tilde.club](mailto:root@tilde.club) if you already have an account)
|
||||
|
||||
#### using your keypair
|
||||
|
||||
once an admin approves your signup, you can join the tilde.club
|
||||
|
||||
1. open a terminal (this depends on your distro)
|
||||
|
||||
1. `ssh` to tilde.club:
|
||||
|
||||
```bash
|
||||
ssh username@tilde.club
|
||||
```
|
||||
|

|

|
||||
<p>while <a href="https://tilde.club">tilde.club</a> is accessible on the web and features lovely web pages written by its users, most interaction with tilde.club takes place <strong>inside the machine</strong> that runs tilde.club as opposed to via web forms that have an effect from <strong>outside</strong> tilde.club’s computer.</p>
|
||||
<p>this is what sets tilde.club apart from most other online communities. you connect directly to another computer from yours alongside other people and then write your web pages, chat, and play games all via text-based interfaces right on tilde.club’s computer.</p>
|
||||
<p>prior to the web (which debuted in 1995) this is how pretty much all computer stuff got done. you connected directly to a machine (usually over a direct, physical phone line) and did your work there.</p>
|
||||
<p>for a long time, people used a tool called <a href="https://en.wikipedia.org/wiki/telnet"><code>telnet</code></a> to connect to other computers. these days we use a tool called <strong>ssh</strong>.</p>
|
||||
<p><code>ssh</code> is a text-based tool that provides a direct connection from your computer to another. ssh is an acronym that stands for secure shell. the <em>shell</em> part refers to the fact that it’s a text-based tool; we use the word shell to refer to a text-based interface that you give commands to. the <em>secure</em> part refers to the fact that, when you’re using ssh, no one can spy on your connection to another computer (unlike the old <code>telnet</code> command).</p>
|
||||
<p><strong>why bother with all of this?</strong> passwords are really insecure and hard to manage. using keys makes life easier for you, fair user (your account is less likely to be hacked) and for me, your humble sysadmin (less administration than passwords).</p>
|
||||
<hr />
|
||||
<h2 id="how-to-make-an-ssh-key">how to make an ssh key</h2>
|
||||
<p>SSH supports a handful of types of cryptographic keys. The most used are <a href="%3Chttps://en.wikipedia.org/wiki/RSA_(cryptosystem)%3E">RSA</a> and the more modern <a href="https://en.wikipedia.org/wiki/EdDSA#Ed25519">Ed25519</a>.</p>
|
||||
<p>RSA is the de-facto standard and is supported everywhere (just choose a big enough key like 4096 bits to be secure). Ed25519 is designed to be faster and smaller withouth sacrificing security, so is best suited for embedded devices or machines with low resources. It’s supported on tilde (and really on any modern system) but you may find older systems which do not support it.</p>
|
||||
<p>Below you’ll find instructions to generate either type (or both if you want).</p>
|
||||
<p>Keep in mind that these instructions leave your private keys unencrypted in your local hard disk. So keep them private; never share them. A good solution is to provide a password for them at creation time, but this implies entering a password any time you used them (impractical) or use something like <a href="https://man.openbsd.org/ssh-agent.1">ssh-agent</a> (a bit more complex)</p>
