title: About the ssh_config Resource

# ssh_config

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

<br>

## 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

<br>

## Examples

The following examples show how to use this 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('GORDON_CLIENT') }
    end

### Test owner and group permissions

    describe ssh_config do
      its('owner') { should eq 'root' }
      its('mode') { should cmp '0644' }
    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

## Matchers

This InSpec audit resource has the following matchers. For a full list of available matchers please visit our [matchers page](https://www.inspec.io/docs/reference/matchers/).

### name

The `name` matcher tests the value of `name` as read from `ssh_config` versus the value declared in the test:

or:

    its('name') { should include('bar') }
