ssh

ssh is what sets ttylde apart from other social networks. you connect directly to another computer's console instead of connecting via a web page or a mobile app.

Before the days of the world-wide-web, this is how all computer work got done.

People used to use a tool called telnet for this purpose. Nowadays, we use ssh.

How to make an ssh key

This method will create two keys: a public and a private key. This is a method of encryption called public key encryption.

Make sure to always keep your private key private! Otherwise, bad people can do bad things while pretending to be you.

If you have any questions, be sure to ask on IRC! The channel is #ttylde.

Generating the keypair

1. Open your terminal
2. Create your .ssh directory if it doesn't exist:

mkdir -m 700 ~/.ssh

3. Create your keys:

ssh-keygen -t ed25519 -a 100

• If you accept the defaults, your public key and private key will be located at ~/.ssh/id_ed25519.pub and ~/.ssh/id_ed25519, respectively.
• Paste the contents of your public key file into the SSH Key field on the signup form

Using the keypair

Once an admin approves your application, simply run the following command to connect:

ssh -i ~/.ssh/your_key_file username@ttylde.karx.xyz

where username is your username (~karx would use karx@ttylde.karx.xyz)

Older versions of windows do not come with ssh preinstalled, and you will need to install a third party tool. Below are some recommendations:

• Windows subsystem for Linux
• msys2
• git bash

After this, follow the instructions above.
