http://tilde.club uses ssh
public-key authentication.
If you want access to tilde.club, create a new key pair with an encrypted key and send the public key to the admins.
##Mac
- Open Terminal (in /Applications/Utilities).
- In the Terminal window, paste the following:
mkdir -p ~/.ssh # Create your .ssh directory ssh-keygen -f ~/.ssh/tilde.club # Create your keys
- The
ssh-keygen
program will generate two new keys (private and public), and prompt you for a password. Please set a good password (at least 9 characters, and not just letters or numbers). Make a note of it somewhere safe. open ~/.ssh # Open your .ssh directory
- Email ford@ (our friendly host) and attach
tilde.club.pub
to the email (it should be visible in the Finder. Do not attachtilde.club
-- that is your private key, which you should never share.
##Linux
If you're on Linux you can use the same commands to generate a tilde.club
keypair, but attaching tilde.club.pub
is left as an exercise for the reader.
##Windows
We need instructions for using PuTTYgen
to create a key in OpenSSH compatible format.
##Why?
ssh
keys are more secure than classic UNIX passwords. Someone who takes over the server (sshd
program) can capture the UNIX passwords of everyone who uses them to login -- this has happened.
Additionally, if you use an ssh
agent, you can login without entering a password every time. On OS X the Apple Keychain provides this functionality. On Linux it's ssh-agent
and possibly keychain. On Windows pageant
provides this capability for PuTTY.
