OpenSSH Server

Ansible role to configure the OpenSSH ssh server. Use Eliptic cureve cryptografie for your ssh keys e.g.:

ssh-keygen -t ed25519

combinations

It is highly recomended to use this role together with a role to manage users and to manage the sshd configuration.
The following roles are tested in combination and work well - at least for the user DO1JLR:

• github.com/chaos-bodensee/role-manage_users
• github.com/chaos-bodensee/role-ssh_authorized_keys
• github.com/chaos-bodensee/role_sshd (this one)

Some Variables explained

Remember: Have a look into defaults/main.yml for all possible variables.

Important part:

Define the users (and optional their ssh keys) for the ssh config template:

users:
  l3d:
    - l3d
  ottojo:
   - ottojo@uni
   - ottojo@home

-> This means l3d and ottojo are able to login.

Don't forget:

• This role will not deploy or touch any ssh public keys. There are other roles to do that.
• Be carefull if you don't have a eliptic curve ed25519 key. only_allow_ed25519: true is the default option.
  • If you really have to deal with RSA Keys or simmilar, you should think about a backup ed25519 ssh key. Better a backup than beeing locked out!
