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::debian # # 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" # # 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_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.
