# Deploy authorized_keys file with the define
# sshd::ssh_authorized_key
#
# sshd-config:
#
# The configuration of the sshd is rather strict and might not fit all
# needs. However there are a bunch of variables, which you might
# consider configuring.
#
# To set any of the following, simply set them as variables in your manifests
# before the class is included, for example:
#
# $sshd_listen_address = ['10.0.0.1 192.168.0.1']
# $sshd_use_pam = yes
# include sshd
#
# If you need to install a version of the ssh daemon or client package other than
# the default one that would be installed by 'ensure => installed', then you can
# set the following variables:
#
# $sshd_ensure_version = "1:5.2p2-6"
# $ssh_ensure_version = "1:5.2p2-6"
#
# To have nagios checks setup automatically for sshd services, simply
# set $use_nagios = true before the class is included. If you want to
# disable ssh nagios checking for a particular node (such as when ssh
# is firewalled), then you can set $nagios_check_ssh to false and that
# node will not be monitored.
# NOTE: this requires that you are using the nagios puppet module
# which supports the nagios native types via nagios::service
#
# The following is a list of the currently available variables:
#
# sshd_listen_address: specify the addresses sshd should listen on
# set this to ['10.0.0.1 192.168.0.1'] to have it listen on both
# addresses, or leave it unset to listen on all
# Default: empty -> results in listening on 0.0.0.0
#
# sshd_allowed_users: list of usernames separated by spaces.
# set this for example to "foobar root"
# to ensure that only user foobar and root
# might login.
# Default: empty -> no restriction is set
#
# sshd_allowed_groups list of groups separated by spaces.
# set this for example to "wheel sftponly"
# to ensure that only users in the groups
# wheel and sftponly might login.
# Default: empty -> no restriction is set
# Note: This is set after sshd_allowed_users,
# take care of the behaviour if you use
# these 2 options together.
#
# sshd_use_pam: if you want to use pam or not for authenticaton
# Values: no or yes.
# Default: no
#
# sshd_permit_root_login: If you want to allow root logins or not.
# Valid values: yes, no, without-password, forced-commands-only
# Default: without-password
#
# sshd_password_authentication: If you want to enable password authentication or not
# Valid values: yes or no
# Default: no
#
# sshd_kerberos_authentication: If you want the password that is provided by the user to be
# validated through the Kerberos KDC. To use this option the
# server needs a Kerberos servtab which allows the verification of
# the KDC's identity.
# Valid values: yes or no
# Default: no
#
# sshd_kerberos_orlocalpasswd: If password authentication through Kerberos fails, then the password
# will be validated via any additional local mechanism.
# Valid values: yes or no
# Default: yes
#
# sshd_kerberos_ticketcleanup: Destroy the user's ticket cache file on logout?
# Valid values: yes or no
# Default: yes
#
# sshd_gssapi_authentication: Authenticate users based on GSSAPI?
# Valid values: yes or no
# Default: no
#
# sshd_gssapi_cleanupcredentials: Destroy user's credential cache on logout?
# Valid values: yes or no
# Default: yes
#
# sshd_challenge_response_authentication: If you want to enable ChallengeResponseAuthentication or not
# When disabled, s/key passowords are disabled
# Valid values: yes or no
# Default: no
#
# sshd_tcp_forwarding: If you want to enable TcpForwarding
# Valid Values: yes or no
# Default: no
#
# sshd_x11_forwarding: If you want to enable x11 forwarding
# Valid Values: yes or no
# Default: no
#
# sshd_agent_forwarding: If you want to allow ssh-agent forwarding
# Valid Values: yes or no
# Default: no
#
# sshd_pubkey_authentication: If you want to enable public key authentication
# Valid Values: yes or no
# Default: yes
#
# sshd_rsa_authentication: If you want to enable RSA Authentication
# Valid Values: yes or no
# Default: no
#
# sshd_rhosts_rsa_authentication: If you want to enable rhosts RSA Authentication
# Valid Values: yes or no
# Default: no
#
# sshd_hostbased_authentication: If you want to enable HostbasedAuthentication
# Valid Values: yes or no
# Default: no
#
# sshd_strict_modes: If you want to set StrictModes (check file modes/ownership before accepting login)
# Valid Values: yes or no
# Default: yes
#
# sshd_permit_empty_passwords: If you want enable PermitEmptyPasswords to allow empty passwords
# Valid Values: yes or no
# Default: no
#
# sshd_port: If you want to specify a different port than the default 22
# Default: 22
#
# sshd_authorized_keys_file: Set this to the location of the AuthorizedKeysFile (e.g. /etc/ssh/authorized_keys/%u)
# Default: AuthorizedKeysFile %h/.ssh/authorized_keys
#
# sshd_sftp_subsystem: Set a different sftp-subystem than the default one.
# Might be interesting for sftponly usage
# Default: empty -> no change of the default
#
# sshd_head_additional_options: Set this to any additional sshd_options which aren't listed above.
# Anything set here will be added to the beginning of the sshd_config file.
# This option might be useful to define complicated Match Blocks
# This string is going to be included, like it is defined. So take care!
# Default: empty -> not added.
#
# sshd_tail_additional_options: Set this to any additional sshd_options which aren't listed above.
# Anything set here will be added to the end of the sshd_config file.
# This option might be useful to define complicated Match Blocks
# This string is going to be included, like it is defined. So take care!
