The default # is /etc/ssh/ssh_host_key for protocol version 1, and # /etc/ssh/ssh_host_rsa_key and /etc/ssh/ssh_host_dsa_key for protocol # version 2. Note that sshd(8) will refuse to use a file if it is # group/world-accessible.

SyslogFacility AUTHPRIV # Gives the verbosity level that is used when logging messages from sshd(8). # The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, # DEBUG1, DEBUG2, and DEBUG3. The default is INFO. DEBUG and DEBUG1 are # equivalent. DEBUG2 and DEBUG3 each specify higher levels of debugging # output. Logging with a DEBUG level violates the privacy of users and is # not recommended. # LogLevel VERBOSE logs user's key fingerprint on login. Needed to have a # clear audit track of which key was using to log in. LogLevel VERBOSE # Authentication: # The server disconnects after this time if the user has not successfully # logged in. If the value is 0, there is no time limit. LoginGraceTime 0 # Specifies whether root can log in using ssh(1). The argument must be # ''yes'', ''without-password'', ''forced-commands-only'', or ''no''. # The default is ''yes''. If this option is set to ''without-password'', # password authentication is disabled for root. If this option is set to # ''forced-commands-only'', root login with public key authentication will # be allowed, but only if the command option has been specified (which # may be useful for taking remote backups even if root login is normally # not allowed). All other authentication methods are disabled for root. # If this option is set to ''no'', root is not allowed to log in. PermitRootLogin no # This keyword can be followed by a list of user name patterns, separated # by spaces. If specified, login is allowed only for user names that match # one of the patterns. Only user names are valid; a numerical user ID is # not recognized. By default, login is allowed for all users. If the pattern # takes the form USER@HOST then USER and HOST are separately checked, # restricting logins to particular users from particular hosts. The # allow/deny directives are processed in the following order: # DenyUsers, AllowUsers, DenyGroups, and finally AllowGroups. AllowUsers django ansible # Specifies whether sshd(8) should check file modes and ownership of the # user's files and home directory before accepting login. This is normally # desirable because novices sometimes accidentally leave their directory # or files world-writable. StrictModes yes # Specifies the maximum number of authentication attempts permitted per # connection. Once the number of failures reaches half this value, # additional failures are logged. MaxAuthTries 10 # Specifies the maximum number of open sessions permitted per network # connection. MaxSessions 10 # Specifies the file that contains the public keys that can be used for # user authentication. AuthorizedKeysFile may contain tokens of the form # %T which are substituted during connection setup. The following tokens # are defined: %% is replaced by a literal '%', %h is replaced by the # home directory of the user being authenticated, and %u is replaced by # the username of that user. After expansion, AuthorizedKeysFile is # taken to be an absolute path or one relative to the user's home directory. AuthorizedKeysFile .ssh/authorized_keys # Specifies whether public key authentication is allowed. The default is # ''yes''. Note that this option applies to protocol version 2 only. PubkeyAuthentication yes #AuthorizedPrincipalsFile none #AuthorizedKeysCommand none #AuthorizedKeysCommandUser nobody # For this to work you will also need host keys in /etc/ssh/ssh_known_hosts #HostbasedAuthentication no # Change to yes if you don't trust ~/.ssh/known_hosts for # HostbasedAuthentication #IgnoreUserKnownHosts no # Don't read the user's ~/.rhosts and ~/.shosts files #IgnoreRhosts yes # To disable tunneled clear text passwords, change to no here! #PasswordAuthentication yes #PermitEmptyPasswords no # Specifies whether password authentication is allowed. To disable tunneled # clear text passwords, change to no here! PasswordAuthentication no # Specifies whether challenge-response authentication is allowed # (e.g. via PAM or though authentication styles supported in login.conf(5)) # Change to no to disable s/key passwords ChallengeResponseAuthentication no # Kerberos options #KerberosAuthentication no #KerberosOrLocalPasswd yes #KerberosTicketCleanup yes #KerberosGetAFSToken no #KerberosUseKuserok yes # Specifies whether user authentication based on GSSAPI is allowed. GSSAPIAuthentication yes # Specifies whether key exchange based on GSSAPI is allowed. GSSAPI key # exchange doesn't rely on ssh keys to verify host identity. #GSSAPIKeyExchange no # Specifies whether to automatically destroy the user's credentials cache # on logout. GSSAPICleanupCredentials no # Determines whether to be strict about the identity of the GSSAPI acceptor # a client authenticates against. If ''yes'' then the client must authenticate # against the host service on the current hostname. If ''no'' then the client # may authenticate against any service key stored in the machine's default # store. This facility is provided to assist with operation on multi homed # machines. The default is ''yes''. Note that this option applies only to # protocol version 2 GSSAPI connections, and setting it to ''no'' may only # work with recent Kerberos GSSAPI libraries. #GSSAPIStrictAcceptorCheck yes #GSSAPIEnablek5users no # Set this to 'yes' to enable PAM authentication, account processing, # and session processing. If this is enabled, PAM authentication will # be allowed through the ChallengeResponseAuthentication and # PasswordAuthentication. Depending on your PAM configuration, # PAM authentication via ChallengeResponseAuthentication may bypass # the setting of "PermitRootLogin without-password". # If you just want the PAM account and session checks to run without # PAM authentication, then enable this but set PasswordAuthentication # and ChallengeResponseAuthentication to 'no'. # WARNING: 'UsePAM no' is not supported in Fedora and may cause several # problems. UsePAM yes # Specifies whether X11 forwarding is permitted. The argument must be # ''yes'' or ''no''. The default is ''no''. # When X11 forwarding is enabled, there may be additional exposure to the # server and to client displays if the sshd(8) proxy display is configured # to listen on the wildcard address (see X11UseLocalhost below), though this # is not the default. Additionally, the authentication spoofing and # authentication data verification and substitution occur on the client side. # The security risk of using X11 forwarding is that the client's X11 display # server may be exposed to attack when the SSH client requests forwarding # (see the warnings for ForwardX11 in ssh_config(5)). A system administrator # may have a stance in which they want to protect clients that may expose # themselves to attack by unwittingly requesting X11 forwarding, which can # warrant a ''no'' setting. Note that disabling X11 forwarding does not # prevent users from forwarding X11 traffic, as users can always install # their own forwarders. X11 forwarding is automatically disabled if UseLogin # is enabled. X11Forwarding yes # Specifies the first display number available for sshd(8)'s X11 forwarding. # This prevents sshd from interfering with real X11 servers. # The default is 10. #X11DisplayOffset 10 # Specifies whether sshd(8) should bind the X11 forwarding server to the # loopback address or to the wildcard address. By default, sshd binds the # forwarding server to the loopback address and sets the hostname part of # the DISPLAY environment variable to ''localhost''. This prevents remote # hosts from connecting to the proxy display. However, some older X11 clients # may not function with this configuration. X11UseLocalhost may be set to # ''no'' to specify that the forwarding server should be bound to the # wildcard address. The argument must be ''yes'' or ''no''. The default is # ''yes''. #X11UseLocalhost yes # Specifies whether ssh-agent(1) forwarding is permitted. The default is # ''yes''. Note that disabling agent forwarding does not improve security # unless users are also denied shell access, as they can always install # their own forwarders. #AllowAgentForwarding yes # Specifies whether TCP forwarding is permitted. The default is ''yes''. # Note that disabling TCP forwarding does not improve security unless users # are also denied shell access, as they can always install their own # forwarders. #AllowTcpForwarding yes # Specifies whether remote hosts are allowed to connect to ports forwarded # for the client. By default, sshd(8) binds remote port forwardings to the # loopback address. This prevents other remote hosts from connecting to # forwarded ports. GatewayPorts can be used to specify that sshd should # allow remote port forwardings to bind to non-loopback addresses, thus # allowing other hosts to connect. The argument may be ''no'' to force # remote port forwardings to be available to the local host only, ''yes'' # to force remote port forwardings to bind to the wildcard address, or # ''clientspecified'' to allow the client to select the address to which # the forwarding is bound. The default is ''no''. #GatewayPorts no #PermitTTY yes # It is recommended to use pam_motd in /etc/pam.d/sshd instead of PrintMotd, # as it is more configurable and versatile than the built-in version. PrintMotd no #PrintLastLog yes #TCPKeepAlive yes #PermitUserEnvironment no #Compression delayed #ClientAliveInterval 0 #ClientAliveCountMax 3 #ShowPatchLevel no #UseDNS no #PidFile /var/run/sshd.pid #MaxStartups 10:30:100 #PermitTunnel no #ChrootDirectory none #VersionAddendum none # The contents of the specified file are sent to the remote user before # authentication is allowed.
