openssh
Install and configure an openssh server.
Note
See the full Salt Formulas installation and usage instructions.
Available states
openssh
Installs the openssh server package and service.
openssh.auth
Manages SSH certificates for users.
openssh.banner
Installs a banner that users see when SSH-ing in.
openssh.client
Installs the openssh client package.
openssh.config
Installs the ssh daemon configuration file included in this formula
(under "openssh/files"). This configuration file is populated
by values from pillar. pillar.example results in the generation
of the default sshd_config file on Debian Wheezy.
openssh.known_hosts
Manages the site-wide ssh_known_hosts file and fills it with the
public SSH host keys of all minions. You can restrict the set of minions
whose keys are listed by using the pillar data openssh:known_hosts:target
and openssh:known_hosts:expr_form (those fields map directly to the
corresponding attributes of the mine.get function).
The Salt mine is used to share the public SSH host keys, you must thus
configure it accordingly on all hosts that must export their keys. Two
mine functions are required, one that exports the keys (one key per line,
as they are stored in /etc/ssh/ssh_host_*_key.pub) and one that defines
the public hostname that the keys are associated to. Here's the way to
setup those functions through pillar:
# Required for openssh.known_hosts
mine_functions:
public_ssh_host_keys:
mine_function: cmd.run
cmd: cat /etc/ssh/ssh_host_*_key.pub
public_ssh_hostname:
mine_function: grains.get
key: id
The above example assumes that the minion identifier is a valid DNS name
that can be used to connect to the host. If that's not the case, you might
want to use the fqdn grain instead of the id one. The above example
also uses the default mine function names used by this formula. If you have to
use other names, then you should indicate the names to use in pillar keys
openssh:known_hosts:mine_keys_function and
openssh:known_hosts:mine_hostname_function.
You can also integrate alternate DNS names of the various hosts in the
ssh_known_hosts files. You just have to list all the alternate DNS names as a
list in the openssh:known_hosts:aliases pillar key. Whenever the IPv4 or
IPv6 behind one of those DNS entries matches an IPv4 or IPv6 behind the
official hostname of a minion, the alternate DNS name will be associated to the
minion's public SSH host key.
openssh.moduli
Manages the system wide /etc/ssh/moduli file.
