Description

Installs openssh.

Requirements

Platform:

  • Debian/Ubuntu
  • RHEL/CentOS/Scientific
  • Fedora
  • ArchLinux

Recipes

default

Selects the packages to install by package name and manages the sshd service.

Usage

Ensure that the openssh packages are installed and the service is managed with recipe[openssh].

Attributes List

The attributes list is dynamically generated, and lines up with the default openssh configs.

This means anything located in sshd_config or ssh_config can be used in your node attributes.

  • If the option can be entered more then once, use an Array, otherwise, use a String.
  • Each attribute is stored as ruby case, and converted to camel case for the config file on the fly.
  • The current default attributes match the stock ssh_config and sshd_config provided by openssh.
  • The namespace for sshd_config is node['openssh']['server'].
  • Likewise, the namespace for ssh_config is node['openssh']['client'].
  • An attribute can be an Array or a String.
  • If it is an Array, each item in the array will get it's own line in the config file.
  • All the values in openssh are commented out in the attributes/default.rb file for a base starting point.

Dynamic ListenAddress

Pass in a Hash of interface names, and IP address type(s) to bind sshd to. This will expand to a list of IP addresses which override the default node['openssh']['server']['listen_address'] value.

Examples and Common usage

These can be mixed and matched in roles and attributes. Please note, it is possible to get sshd into a state that it will not run. If this is the case, you will need to login via an alternate method and debug sshd like normal.

No Password logins.

This requires use of identity files to connect

"openssh": {
    "server": {
        "password_authentication": "no"
    }
}

Enable X Forwarding

"openssh": {
    "server": {
        "x11_forwarding": "yes"
    }
}

Bind to a specific set of address (this example actually binds to all).

Not to be used with node['openssh']['listen_interfaces'].

"openssh": {
    "server": {
        "address_family": "any",
        "listen_address": [ "192.168.0.1", "::" ]
    }
}

Bind to the addresses tied to a set of interfaces.

"openssh": {
    "listen_interfaces": {
        "eth0": "inet",
        "eth1": "inet6"
    }
}
