# etc_hosts
|
|
|
|
Use the `etc_hosts` InSpec audit resource to test rules set to match IP addresses with hostnames.
|
|
## Syntax
|
|
|
|
An etc/hosts rule specifies an IP address and what its hostname is along with optional aliases it can have.
|
|
|
|
<br>
|
|
|
|
## Syntax
|
|
|
|
Use the where clause to match a property to one or more rules in the hosts file.
|
|
|
|
describe etc_hosts.where { ip_address == 'value' } do
|
|
its('primary_name') { should cmp 'hostname' }
|
|
its('all_host_names') { should cmp 'list' }
|
|
end
|
|
|
|
Use the optional constructor parameter to give an alternative path to hosts file
|
|
|
|
describe etc_hosts('path/to/hosts').where { ip_address == 'value' } do
|
|
its('primary_name') { should cmp 'hostname' }
|
|
its('all_host_names') { should cmp 'list' }
|
|
end
|
|
|
|
where
|
|
|
|
* `ip_address` is the ip address of the hostname in either ipv4 or ipv6 format.
|
|
* `primary_name` is the name associated with the ip address.
|
|
* `all_host_names` is a list including the primary_name as the first entry followed by any aliase names the host has.
