# limits_conf
|
|
|
|
Use the `limits_conf` Chef InSpec audit resource to test configuration settings in the `/etc/security/limits.conf` file. The `limits.conf` defines limits for processes (by user and/or group names) and helps ensure that the system running those processes remains stable. Each process may be assigned a hard or soft limit.
|
|
|
|
* Soft limits are maintained by the shell and defines the number of file handles (or open files) available to the user or group after login
|
|
* Hard limits are maintained by the kernel and defines the maximum number of allowed file handles
|
|
|
|
Entries in the `limits.conf` file are similar to:
|
|
|
|
grantmc soft nofile 4096
|
|
grantmc hard nofile 63536

## Availability
|
|
|
|
### Installation
|
|
|
|
This resource is distributed along with Chef InSpec itself. You can use it automatically.
|
|
|
|
### Version
|
|
|
|
This resource first became available in v1.0.0 of InSpec.
|
|
|
|
## Syntax
|
|
|
|
A `limits_conf` resource block declares a domain to be tested, along with associated type, item, and value:
|
|
|
|
describe limits_conf('path') do
|
|
its('domain') { should include ['type', 'item', 'value'] }
|
|
its('domain') { should eq ['type', 'item', 'value'] }
|
|
end
|
|
|
|
where
|
|
|
|
* `('path')` is the non-default path to the `inetd.conf` file
|
|
* `'domain'` is a user or group name, such as `grantmc`
|
|
* `'type'` is either `hard` or `soft`
|
|
* `'item'` is the item for which limits are defined, such as `core`, `nofile`, `stack`, `nproc`, `priority`, or `maxlogins`
|
|
* `'value'` is the value associated with the `item`
|
|
|

## Examples
|
|
|
|
The following examples show how to use this Chef InSpec audit resource.
|
|
|
|
### domain
|
|
|
|
The `domain` property tests the domain in the `limits.conf` file, along with associated type, item, and value:
|
|
|
|
its('domain') { should include ['type', 'item', 'value'] }
|
|
`
|
|
For example:
|
|
|
|
its('grantmc') { should include ['hard', 'nofile', '63536'] }
|
|
|
|
### Test limits
|
|
|
|
describe limits_conf('path') do
|
|
its('*') { should include ['soft', 'core', '0'], ['hard', 'rss', '10000'] }
|
|
its('ftp') { should eq ['hard', 'nproc', '0'] }
|
|
end
|
