##Overview

Module for configuring ssh on your Centos, Debian, Redhat, Ubuntu node.

##Module Description

The module makes it possible to install a ssh server and/or client and to add authorized ssh keys to existing users.

##Setup

###What attachmentgenie/ssh affects

• ssh server
• ssh client
• add authorized ssh keys to existing users.

###Beginning with attachmentgenie/ssh

The ssh::client class installs the ssh client:

class { 'ssh::client': }

The ssh::server class installs and configures the sshd:

class { 'ssh::server': }

##Usage

You can specify the port the sshd should listen to by including the class with this special syntax:

class { 'ssh::server':
  port => 20009,
}

You can also restrict access for only certain users:

class { 'ssh::server':
  allowed_users => ['uggedal', 'manager'],
}

And you can permit root logins (not recommended):

class { 'ssh::server':
  permit_root_login => 'yes',
}

To permit root logins could be a serious security issue. In most cases you should use something like sudo instead.

You can use ssh::user to add an authorized ssh key to an existing user for effortless authentication with ssh:

ssh::user { 'uggedal':
  key => 'a8a7dgf7ad8j13g',
  comment => 'uggedal.com',
}
