OpenSSH Server
|
|
==============
|
|
|
|
This role configures the OpenSSH daemon. It:
|
|
|
|
* By default configures the SSH daemon with the normal OS defaults.
|
|
* Works across a variety of UN*X like distributions
|
|
* Can be configured by dict or simple variables
|
|
* Supports Match sets
|
|
* Supports all sshd_config options. Templates are programmatically generated.
|
|
(see [meta/make_option_list](meta/make_option_list))
|
|
* Tests the sshd_config before reloading sshd.
|
|
|
|
**WARNING** Misconfiguration of this role can lock you out of your server!
|
|
Please test your configuration and its interaction with your users configuration
|
|
before using in production!
|
|
|
|
**WARNING** Digital Ocean allows root with passwords via SSH on Debian and
|
|
Ubuntu. This is not the default assigned by this module - it will set
|
|
`PermitRootLogin without-password` which will allow access via SSH key but not
|
|
via simple password. If you need this functionality, be sure to set
|
|
`ssh_PermitRootLogin yes` for those hosts.
|
|
|
|
Requirements
|
|
------------
|
|
|
|
Tested on:
|
|
|
|
* Ubuntu precise, trusty
|
|
* Debian wheezy, jessie
|
|
* FreeBSD 10.1
|
|
* EL 6,7 derived distributions
|
|
* Fedora 20, 22
|
|
|
|
It will likely work on other flavours and more direct support via suitable
|
|
[vars/](vars/) files is welcome.
|
|
|
|
Role variables
|
|
---------------
|
|
|
|
Unconfigured, this role will provide a sshd_config that matches the OS default,
|
|
minus the comments and in a different order.
|
|
|
|
* sshd_skip_defaults
|
|
|
|
If set to True, don't apply default values. This means that you must have a
|
|
complete set of configuration defaults via either the sshd dict, or sshd_Key
|
|
variables. Defaults to *False*.
|
|
|
|
* sshd_manage_service
|
|
|
|
If set to False, the service/daemon won't be touched at all, i.e. will not try
|
|
to enable on boot or start or reload the service. Defaults to *True* unless
|
|
running inside a docker container (it is assumed ansible is used during build
|
|
phase).
|
|
|
|
* sshd_allow_reload
|
|
|
|
If set to False, a reload of sshd wont happen on change. This can help with
|
|
troubleshooting. You'll need to manually reload sshd if you want to apply the
|
|
changed configuration. Defaults to the same value as ``sshd_manage_service``.
|
|
|
|
* sshd
|
|
|
|
A dict containing configuration. e.g.
|
|
|
|
```yaml
|
|
sshd:
|
|
Compression: delayed
|
|
ListenAddress:
|
|
- 0.0.0.0
|
|
```
|
|
|
|
* ssh_...
|
|
|
|
Simple variables can be used rather than a dict. Simple values override dict
|
|
values. e.g.:
|
|
|
|
```yaml
|
|
sshd_Compression: off
|
|
```
|
|
|
|
In all cases, booleans correctly rendered as yes and no in sshd configuration.
|
|
Lists can be used for multiline configuration items. e.g.
|
|
|
|
```yaml
|
|
sshd_ListenAddress:
|
|
- 0.0.0.0
|
|
- '::'
|
|
```
|
|
|
|
Renders as:
|
|
|
|
```
|
|
ListenAddress 0.0.0.0
|
|
ListenAddress ::
|
|
```
|
|
|
|
* sshd_match
|
|
|
|
A list of dicts for a match section. See the example playbook.
|
|
|
|
* sshd_match_1 through sshd_match_9
|
|
|
|
A list of dicts or just a dict for a Match section.
|
|

Example Playbook
|
|
----------------
|
|
|
|
```yaml
|
|
---
|
|
- hosts: all
|
|
vars:
|
|
sshd_skip_defaults: true
|
|
sshd:
|
|
Compression: true
|
|
ListenAddress:
|
|
- "0.0.0.0"
|
|
- "::"
|
|
GSSAPIAuthentication: no
|
|
Match:
|
|
- Condition: "Group user"
|
|
GSSAPIAuthentication: yes
|
|
sshd_UsePrivilegeSeparation: sandbox
|
|
sshd_match:
|
|
- Condition: "Group xusers"
|
|
X11Forwarding: yes
|
|
roles:
|
|
- role: willshersystems.sshd
|
|
```
|
|
|
|
Results in:
|
|
|
|
```
|
|
# Ansible managed: ...
|
|
Compression yes
|
|
GSSAPIAuthentication no
|
|
UsePrivilegeSeparation sandbox
|
|
Match Group user
|
|
GSSAPIAuthentication yes
|
|
Match Group xusers
|
|
X11Forwarding yes
|
|
```
|
|
|
|
Template Generation
|
|
-------------------
|
|
|
|
The [sshd_config.j2](templates/sshd_config.j2) template is programatically
|
|
generated by the scripts in meta. New options should be added to the
|
|
options_body or options_match.
|
|
|
|
To regenerate the template, from within the meta/ directory run:
|
|
`./make_option_list >../templates/sshd_config.j2`
