Uncommented options change a # default value. # Note that some of FreeBSD's defaults differ from OpenBSD's, and # FreeBSD has a few additional options. #VersionAddendum FreeBSD-20100308 <%- unless sshd_head_additional_options.to_s.empty? then %> <%= sshd_head_additional_options %> <%- end %> <%- unless sshd_port.to_s.empty? then -%> <%- if sshd_port.to_s == 'off' then -%> #Port -- disabled by puppet <% else -%> Port <%= sshd_port -%> <% end -%> <%- else -%> Port 22 <%- end -%> #AddressFamily any <% for address in sshd_listen_address -%> ListenAddress <%= address %> <% end -%> # The default requires explicit activation of protocol 1 Protocol 2 # HostKey for protocol version 1 #HostKey /etc/ssh/ssh_host_key # HostKeys for protocol version 2 HostKey /etc/ssh/ssh_host_rsa_key HostKey /etc/ssh/ssh_host_dsa_key # Lifetime and size of ephemeral version 1 server key #KeyRegenerationInterval 1h #ServerKeyBits 1024 # Logging # obsoletes QuietMode and FascistLogging SyslogFacility AUTH LogLevel INFO # Authentication: LoginGraceTime 600 <%- unless sshd_permit_root_login.to_s.empty? then -%> PermitRootLogin <%= sshd_permit_root_login -%> <%- else -%> PermitRootLogin without-password <%- end -%> <%- if sshd_strict_modes.to_s == 'yes' then -%> StrictModes yes <%- else -%> StrictModes no <%- end -%> #MaxAuthTries 6 #MaxSessions 10 <%- if sshd_rsa_authentication.to_s == 'yes' then -%> RSAAuthentication yes <%- else -%> RSAAuthentication no <%- end -%> <%- if sshd_pubkey_authentication.to_s == 'yes' then -%> PubkeyAuthentication yes <%- else -%> PubkeyAuthentication no <%- end -%> <%- unless sshd_authorized_keys_file.to_s.empty? then -%> AuthorizedKeysFile <%= sshd_authorized_keys_file %> <%- else -%> AuthorizedKeysFile %h/.ssh/authorized_keys <%- end -%> # For this to work you will also need host keys in /etc/ssh/ssh_known_hosts <%- if sshd_rhosts_rsa_authentication.to_s == 'yes' then -%> RhostsRSAAuthentication yes <%- else -%> RhostsRSAAuthentication no <% end -%> # similar for protocol version 2 <%- if sshd_hostbased_authentication.to_s == 'yes' then -%> HostbasedAuthentication yes <%- else -%> HostbasedAuthentication no <% end -%> # Change to yes if you don't trust ~/.ssh/known_hosts for # RhostsRSAAuthentication and HostbasedAuthentication #IgnoreUserKnownHosts no # Don't read the user's ~/.rhosts and ~/.shosts files #IgnoreRhosts yes # Change to yes to enable built-in password authentication. <%- if sshd_password_authentication.to_s == 'yes' then -%> PasswordAuthentication yes <%- else -%> PasswordAuthentication no <%- end -%> <%- if sshd_permit_empty_passwords.to_s == 'yes' then -%> PermitEmptyPasswords yes <% else -%> PermitEmptyPasswords no <% end -%> # Change to no to disable PAM authentication <%- if sshd_challenge_response_authentication.to_s == 'yes' then -%> ChallengeResponseAuthentication yes <%- else -%> ChallengeResponseAuthentication no <%- end -%> # Kerberos options <%- if sshd_kerberos_authentication.to_s == 'yes' then -%> KerberosAuthentication yes <%- else -%> KerberosAuthentication no <%- end -%> <%- if sshd_kerberos_orlocalpasswd.to_s == 'yes' then -%> KerberosOrLocalPasswd yes <%- else -%> KerberosOrLocalPasswd no <%- end -%> <%- if sshd_kerberos_ticketcleanup.to_s == 'yes' then -%> KerberosTicketCleanup yes <%- else -%> KerberosTicketCleanup no <%- end -%> # GSSAPI options <%- if sshd_gssapi_authentication.to_s == 'yes' then -%> GSSAPIAuthentication yes <%- else -%> GSSAPIAuthentication no <%- end -%> <%- if sshd_gssapi_authentication.to_s == 'yes' then -%> GSSAPICleanupCredentials yes <%- else -%> GSSAPICleanupCredentials yes <%- end -%> # Set this to 'no' to disable PAM authentication, account processing, # and session processing.
