Description
This cookbook maintains the openssh server.
Unlike other sshd cookbooks, this cookbook respects the default settings of the
current operating systems, unless these settings are explicitly overwritten.
This cookbook takes (or at least tries to) the default sshd configruation of the
distribution you are using as a default. Then you can overwrite specific
settings.
See below for the default settings.
Attributes
You can specify the package that installs sshd, using the following attribute.
There's defaults for most linux distributions.
node['sshd']['package'] # package to install openssh-server
The following settings will be filled in using the defaults of the distribution you're using, unless you overwrite it in your node configuration / definition
node['sshd']['config_file'] # path to sshd_config node['sshd']['service_name'] # sshd service name
You can specify every configuration option that openssh-server supports in the
sshd_config
attribute. The settings you specify will be merged with the
distributions default settings.
node['sshd']['sshd_config']['Port'] = 22
Conditional blocks are defined using hashes
node['sshd']['sshd_config']['Match']['User fred']['X11Forwarding'] = 'no' node['sshd']['sshd_config']['Match'] = { 'User john' => { 'ChrootDirectory' => '/srv', 'ForceCommand' => 'internal-sftp', 'AllowTcpForwarding' => 'no', 'X11Forwarding' => 'no' } }
Some configuration options can be specified multiple times. You can reflect this
using an array
node['sshd']['sshd_config']['HostKey'] = %w{key1 key2}
Recipes
default
Runs the install recipe, then configures openssh-server according to the node attributes.
install
Just installs openssh-server without configuring it, as well as enabling and starting the daemon.
Definitions
You can also maintain openssh-server using the definition. This is the
recommended way.
To use the definition, make sure your metadata.rb includes
depends 'sshd'
openssh_server
To install and configure openssh-server from other recipes, use the following definition:
openssh_server node['sshd']['config_file']
or, if you need a configuration which differs from the default
openssh_server '/etc/sshd_config' do Port 1234 X11Forward 'no' end
The definition accepts all configuration options sshd_config supports.
openssh_server node['sshd']['config_file'] do Port 1234 X11Forward 'yes' # To specify an option multiple times, use an array HostKey %w{/etc/ssh/ssh_host_dsa_key /etc/ssh/ssh_host_rsa_key} # For conditional blocks, use a hash Match 'User fred' => { 'X11Forwarding' => 'no' }, 'User john' => { 'ChrootDirectory' => '/srv', 'ForceCommand' => 'internal-sftp', 'AllowTcpForwarding' => 'no', 'X11Forwarding' => 'no' } end
In case you need it, you can also use a custom template to use for sshd_config
openssh_server node['sshd']['config_file'] do cookbook 'mycookbook' source 'mytemplate.erb' end
