ssh_config resource

Use the ssh_config Chef InSpec audit resource to test OpenSSH client configuration data located at /etc/ssh/ssh_config on Linux and Unix platforms.

Availability

Install

This resource is distributed with Chef InSpec and is automatically available for use.

Version

This resource first became available in v1.0.0 of InSpec.

Syntax

An ssh_config resource block declares the client OpenSSH configuration data to be tested:

describe ssh_config('path') do
  its('name') { should include('foo') }
end

where

  • name is a configuration setting in ssh_config
  • ('path') is the non-default /path/to/ssh_config
  • { should include('foo') } tests the value of name as read from ssh_config versus the value declared in the test

Examples

The following examples show how to use this Chef InSpec audit resource.

Test SSH configuration settings

describe ssh_config do
  its('cipher') { should contain '3des' }
  its('port') { should eq '22' }
  its('hostname') { should include('example.com') }
end

Test which variables from the local environment are sent to the server

only_if do
  command('sshd').exist? or command('ssh').exists?
end

describe ssh_config do
  its('SendEnv') { should include('CI_ENABLE_COVERAGE') }
end

Test SSH configuration

describe ssh_config do
  its('Host') { should eq '*' }
  its('Tunnel') { should eq nil }
  its('SendEnv') { should eq 'LANG LC_*' }
  its('HashKnownHosts') { should eq 'yes' }
end
