# sshd_config
|
|
|
|
Use the `sshd_config` InSpec audit resource to test configuration data for the OpenSSH daemon located at `/etc/ssh/sshd_config` on Linux and Unix platforms. sshd---the OpenSSH daemon---listens on dedicated ports, starts a daemon for each incoming connection, and then handles encryption, authentication, key exchanges, command execution, and data exchanges.

## Syntax
|
|
|
|
An `sshd_config` resource block declares the client OpenSSH configuration data to be tested:
|
|
|
|
describe sshd_config('path') do
|
|
its('name') { should include('foo') }
|
|
end
|
|
|
|
where
|
|
|
|
* `name` is a configuration setting in `sshd_config`
|
|
* `('path')` is the non-default `/path/to/sshd_config`
|
|
* `{ should include('foo') }` tests the value of `name` as read from `sshd_config` versus the value declared in the test

## Examples
|
|
|
|
The following examples show how to use this InSpec audit resource.
|
|
|
|
### Test which variables may be sent to the server
|
|
|
|
describe sshd_config do
|
|
its('AcceptEnv') { should include('GORDON_SERVER') }
|
|
end
|
|
|
|
### Test for IPv6-only addresses
|
|
|
|
describe sshd_config do
|
|
its('AddressFamily') { should cmp 'inet6' }
|
|
end
|
|
|
|
### Test the Protocol setting
|
|
|
|
describe sshd_config do
|
|
its('Protocol') { should cmp 2 }
|
|
end
|
|
|
|
### Test for approved, strong ciphers
|
|
|
|
describe sshd_config do
|
|
its('Ciphers') { should cmp('chacha20-poly1305@openssh.com,aes256-ctr,aes192-ctr,aes128-ctr') }
|
|
end
|
|
|
|
### Test SSH protocols
|
|
|
|
describe sshd_config do
|
|
its('Port') { should cmp 22 }
|
|
its('UsePAM') { should eq 'yes' }
|
|
its('ListenAddress') { should eq nil }
|
|
its('HostKey') { should eq [
|
|
'/etc/ssh/ssh_host_rsa_key',
|
|
'/etc/ssh/ssh_host_dsa_key',
|
|
'/etc/ssh/ssh_host_ecdsa_key',
|
|
] }
|
|
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 `sshd_config` versus the value declared in the test:
|
|
|
|
its('name') { should cmp 'foo' }
|
|
|
|
or:
|
|
|
|
its('name') {should include('bar') }
|
