NAME

       sudo_logsrvd.conf — configuration for sudo_logsrvd

DESCRIPTION

       The sudo_logsrvd.conf file is used to configure the sudo_logsrvd log server.  It uses an INI-style format
       made up of sections in square brackets and “key = value” pairs specific to each section below the section
       name.  Depending on the key, values may be integers, booleans, or strings.  Section and key names are not
       case sensitive, but values are.

       The pound sign (‘#’) is used to indicate a comment.  Both the comment character and any text after it, up
       to the end of the line, are ignored.  Lines beginning with a semi-colon (‘;’) are also ignored.

       Long  lines  can  be  continued  with a backslash (‘\’) as the last character on the line.  Leading white
       space is removed from the beginning of lines even when the continuation character is used.

       The “EXAMPLES” section contains a copy of the default sudo_logsrvd.conf file.

       The following configuration sections are recognized:

          server
          relay
          iolog
          eventlog
          syslog
          logfile

       Each section is described in detail below.

   server
       The server section configures the address and port the server will listen on.   The  following  keys  are
       recognized:

       listen_address = host[:port][(tls)]
             The  host  name  or IP address, optional port to listen on and an optional Transport Layer Security
             (TLS) flag in parentheses.

             The host may be a host name, an IPv4 address, an IPv6 address in square brackets or the  wild  card
             entry  ‘*’.   A  host  setting  of  ‘*’ will cause sudo_logsrvd to listen on all configured network
             interfaces.

             If the optional tls flag is present, sudo_logsrvd will secure the connection with TLS  version  1.2
             or  1.3.   Versions  of  TLS  prior  to  1.2 are not supported.  See sudo_logsrvd(8) for details on
             generating TLS keys and certificates.

             If a port is specified, it may either be a port number or a known service name as  defined  by  the
             system  service  name  database.   If  no  port is specified, port 30343 will be used for plaintext
             connections and port 30344 will be used for TLS connections.

             The default value is:
                   listen_address = *:30343
                   listen_address = *:30344(tls)
             which will listen on all configured network interfaces for  both  plaintext  and  TLS  connections.
             Multiple listen_address lines may be specified to listen on more than one port or interface.

       server_log = string
             Where  to  log  server warning and error messages.  Supported values are none, stderr, syslog, or a
             path name beginning with the ‘/’ character.  A value of stderr  is  only  effective  when  used  in
             conjunction with the -n option.  The default value is syslog.

       pid_file = path
             The  path  to  the  file containing the process ID of the running sudo_logsrvd.  If set to an empty
             value, or if sudo_logsrvd is run with the -n option, no pid_file  will  be  created.   If  pid_file
             refers to a symbolic link, it will be ignored.  The default value is /run/sudo/sudo_logsrvd.pid.

       tcp_keepalive = boolean
             If  true,  sudo_logsrvd will enable the TCP keepalive socket option on the client connection.  This
             enables the periodic transmission of keepalive messages to the client.   If  the  client  does  not
             respond to a message in time, the connection will be closed.  Defaults to true.

       timeout = number
             The  amount  of  time,  in seconds, sudo_logsrvd will wait for the client to respond.  A value of 0
             will disable the timeout.  The default value is 30.

       tls_cacert = path
             The path to a certificate authority bundle file, in PEM format, to  use  instead  of  the  system's
             default  certificate  authority  database  when  authenticating  clients.   The  default  is to use
             /etc/ssl/sudo/cacert.pem if  it  exists,  otherwise  the  system's  default  certificate  authority
             database is used.

       tls_cert = path
             The   path   to   the   server's   certificate   file,   in  PEM  format.   The  default  value  is
             /etc/ssl/sudo/certs/logsrvd_cert.pem.

       tls_checkpeer = bool
             If true, client certificates will be validated by sudo_logsrvd; clients without a valid certificate
             will be unable to connect.  If false, no validation of client certificates will be  performed.   It
             true  and  client  certificates  are  created using a private certificate authority, the tls_cacert
             setting must be set to a CA bundle that contains the CA certificate used  to  generate  the  client
             certificate.  The default value is false.

       tls_ciphers_v12 = string
             A list of ciphers to use for connections secured by TLS version 1.2 only, separated by a colon ‘:’.
             See  the “CIPHER LIST FORMAT” section in openssl-ciphers(1) for full details.  The default value is
             “HIGH:!aNULL” which consists of encryption cipher suites with key lengths larger than 128 bits, and
             some cipher suites with 128-bit keys.  Cipher suites that offer no authentication are excluded.

       tls_ciphers_v13 = string
             A list of ciphers to use for connections secured by TLS version 1.3 only, separated by a colon ‘:’.
             Supported cipher suites depend on the version of OpenSSL used, but should include the following:

                   TLS_AES_128_GCM_SHA256
                   TLS_AES_256_GCM_SHA384
                   TLS_CHACHA20_POLY1305_SHA256
                   TLS_AES_128_CCM_SHA256
                   TLS_AES_128_CCM_8_SHA256

             The default cipher suite is “TLS_AES_256_GCM_SHA384”.

       tls_dhparams = path
             The path to a file containing custom Diffie-Hellman parameters in PEM format.   This  file  can  be
             created with the following command:

             openssl dhparam -out /etc/sudo_logsrvd_dhparams.pem 2048

             By default, sudo_logsrvd will use the OpenSSL defaults for Diffie-Hellman key generation.

       tls_key = path
             The   path   to   the   server's   private   key  file,  in  PEM  format.   The  default  value  is
             /etc/ssl/sudo/private/logsrvd_key.pem.

       tls_verify = bool
             If true, sudo_logsrvd will validate its own certificate at startup time or when  the  configuration
             is  changed.   If  false, no verification is performed of the server certificate.  When using self-
             signed certificates without a certificate authority, this setting should  be  set  to  false.   The
             default value is true.

   relay
       The relay section configures the optional logsrv relay host and port the server will connect to.  The TLS
       configuration  keys are optional, by default the corresponding keys in the “server” section will be used.
       They are only present in this section to make it possible for the relay connection to use a different set
       of TLS parameters from the client-facing server.  The following keys are recognized:

       connect_timeout = number
             The amount of time, in seconds, sudo_logsrvd will wait for the  connection  to  a  relay_host  (see
             below)  to  complete.   Once the connection is complete, the timeout setting controls the amount of
             time sudo_logsrvd will wait for the relay to respond.  A value of 0 will disable the timeout.   The
             default value is 30.

       relay_dir = path
             The  directory in which log messages are temporarily stored before they are sent to the relay host.
             Messages are stored in the wire format specified  by  sudo_logsrv.proto(5)  The  default  value  is
             /var/log/sudo_logsrvd.

       relay_host = host[:port][(tls)]
             The  relay  host  name  or  IP address, optional port to connect to and an optional Transport Layer
             Security (TLS) flag in parentheses.  The syntax is identical  to  listen_address  in  the  “server”
             section with one exception: the wild card ‘*’ syntax is not supported.

             When  this  setting  is enabled, messages from the client will be forwarded to one of the specified
             relay hosts instead of being stored locally.  The host could be running an instance of sudo_logsrvd
             or another server that supports the sudo_logsrv.proto(5) protocol.

             If multiple relay_host lines are specified, the first available relay host will be used.

       retry_interval = number
             The number of seconds to wait after a connection error before making a new  attempt  to  forward  a
             message to a relay host.  The default value is 30.

       store_first = boolean
             If  true,  sudo_logsrvd  will store logs locally before relaying them.  Once the log is complete, a
             connection to the relay host is opened and the log  is  relayed.   If  the  network  connection  is
             interrupted  before  the log can be fully transferred, it will be retransmitted later.  The default
             is to relay logs in real-time.

       tcp_keepalive = boolean
             If true, sudo_logsrvd will enable the TCP keepalive socket option on the  relay  connection.   This
             enables the periodic transmission of keepalive messages to the relay server.  If the relay does not
             respond to a message in time, the connection will be closed.

       timeout = number
             The  amount  of  time,  in  seconds, sudo_logsrvd will wait for the relay server to respond after a
             connection has succeeded.  A value of 0 will disable the timeout.  The default value is 30.

       tls_cacert = path
             The path to a certificate authority bundle file, in PEM format, to  use  instead  of  the  system's
             default  certificate  authority  database  when  authenticating clients.  The default is to use the
             value specified in the “server” section, or the system's default certificate authority database  if
             no value is set.

       tls_cert = path
             The  path  to  the  server's  certificate  file,  in  PEM  format.  The default is to use the value
             specified in the “server” section.

       tls_checkpeer = bool
             If true, the relay host's certificate will be validated by sudo_logsrvd;  connections  to  a  relay
             without  a  valid  certificate  will  fail.   If false, no validation of relay certificates will be
             performed.  It true and relay certificates are created using a private certificate  authority,  the
             tls_cacert setting must be set to a CA bundle that contains the CA certificate used to generate the
             relay certificate.  The default is to use the value specified in the “server” section.

       tls_ciphers_v12 = string
             A list of ciphers to use for connections secured by TLS version 1.2 only, separated by a colon ‘:’.
             See the “CIPHER LIST FORMAT” section in openssl-ciphers(1) for full details.  The default is to use
             the value specified in the “server” section.

       tls_ciphers_v13 = string
             A list of ciphers to use for connections secured by TLS version 1.3 only, separated by a colon ‘:’.
             Supported  cipher  suites  depend on the version of OpenSSL used, see the “server” section for more
             information.  The default is to use the value specified in the “server” section.

       tls_dhparams = path
             The path to a file containing custom Diffie-Hellman parameters in PEM format.  The  default  is  to
             use the value specified in the “server” section.

       tls_key = path
             The  path  to  the  server's  private  key  file,  in  PEM format.  The default is to use the value
             specified in the “server” section.

       tls_verify = bool
             If true, the server's certificate used for relaying will be verified  at  startup.   If  false,  no
             verification is performed of the server certificate.  When using self-signed certificates without a
             certificate  authority,  this  setting  should  be  set  to false.  The default is to use the value
             specified in the “server” section.

   iolog
       The iolog section configures I/O log parameters.  These settings are identical to the  I/O  configuration
       in sudoers(5).  The following keys are recognized:

       iolog_compress = boolean
             If  set,  I/O  logs will be compressed using zlib.  Enabling compression can make it harder to view
             the logs in real-time as the program is executing due to buffering.  The default value is false.

       iolog_dir = path
             The top-level directory to use when constructing the path name for  the  I/O  log  directory.   The
             session   sequence   number,   if   any,  is  stored  in  the  directory.   The  default  value  is
             /var/log/sudo-io.

             The following percent (‘%’) escape sequences are supported:

             %{seq}
                   expanded to a monotonically increasing base-36 sequence number, such as 0100A5,  where  every
                   two digits are used to form a new directory, e.g., 01/00/A5

             %{user}
                   expanded to the invoking user's login name

             %{group}
                   expanded to the name of the invoking user's real group-ID

             %{runas_user}
                   expanded to the login name of the user the command will be run as (e.g., root)

             %{runas_group}
                   expanded to the group name of the user the command will be run as (e.g., wheel)

             %{hostname}
                   expanded to the local host name without the domain name

             %{command}
                   expanded to the base name of the command being run

             In addition, any escape sequences supported by the system's strftime(3) function will be expanded.

             To include a literal ‘%’ character, the string ‘%%’ should be used.

       iolog_file = path
             The path name, relative to iolog_dir, in which to store I/O logs.  It is possible for iolog_file to
             contain directory components.  The default value is “%{seq}”.

             See the iolog_dir setting above for a list of supported percent (‘%’) escape sequences.

             In  addition  to  the  escape  sequences,  path  names  that end in six or more Xs will have the Xs
             replaced with a unique combination of digits and letters, similar to the mktemp(3) function.

             If the path created by concatenating iolog_dir and iolog_file already exists, the existing I/O  log
             file will be truncated and overwritten unless iolog_file ends in six or more Xs.

       iolog_flush = boolean
             If  set,  I/O  log data is flushed to disk after each write instead of buffering it.  This makes it
             possible to view the logs in real-time as the program is executing but may significantly reduce the
             effectiveness of I/O log compression.  I/O logs are always flushed before sending a commit point to
             the client regardless of this setting.  The default value is true.

       iolog_group = name
             The group name to look up when setting the group-ID on new  I/O  log  files  and  directories.   If
             iolog_group  is  not  set,  the  primary  group-ID  of the user specified by iolog_user is used. If
             neither iolog_group nor iolog_user are set, I/O log files and directories are created with group-ID
             0.

       iolog_mode = mode
             The file mode to use when creating I/O log files.  Mode bits for read  and  write  permissions  for
             owner,  group,  or other are honored, everything else is ignored.  The file permissions will always
             include the owner read and write bits, even if they are not present in the  specified  mode.   When
             creating  I/O  log  directories,  search  (execute) bits are added to match the read and write bits
             specified by iolog_mode.  The default value is 0600.

       iolog_user = name
             The user name to look up when setting  the  owner  of  new  I/O  log  files  and  directories.   If
             iolog_group  is  set,  it will be used instead of the user's primary group-ID.  By default, I/O log
             files and directories are created with user and group-ID 0.

       log_passwords = bool
             Most programs that require a user's password will disable echo before reading the password to avoid
             displaying the plaintext password on the screen.  However, if terminal input is being  logged,  the
             password will still be present in the I/O log.  If log_passwords is set to false, sudo_logsrvd will
             attempt  to  prevent passwords from being logged.  It does this by using the regular expressions in
             passprompt_regex to match a password prompt in the terminal output buffer.  When a match is  found,
             input  characters  in  the  I/O  log will be replaced with ‘*’ until either a line feed or carriage
             return is found in the terminal input or a new terminal output buffer is received.  If, however,  a
             program  displays  characters  as  the  user types them (such as sudo when the pwfeedback option is
             set), only the first character of the password will be replaced in the I/O log.  The default  value
             is true.

       maxseq = number
             The  maximum  sequence  number that will be substituted for the “%{seq}” escape in the I/O log file
             (see the iolog_dir description above for  more  information).   While  the  value  substituted  for
             “%{seq}”  is  in  base  36,  maxseq  itself  should  be  expressed  in decimal.  Values larger than
             2176782336 (which corresponds to the base 36 sequence number “ZZZZZZ”) will be  silently  truncated
             to 2176782336.  The default value is 2176782336.

       passprompt_regex = string
             One  or  more  POSIX  extended  regular  expressions used to match password prompts in the terminal
             output when log_passwords is disabled.  As an extension, if  the  regular  expression  begins  with
             “(?i)”, it will be matched in a case-insensitive manner.  Multiple passprompt_regex settings may be
             specified.   Each  regular  expression  is  limited  to  1024  characters.   The  default  value is
             “[Pp]assword[: ]*”.

   eventlog
       The eventlog section configures how (and if) security policy events are logged.

       log_type = string
             Where to log accept, reject, and alert events reported by the policy.  Supported values are syslog,
             logfile, and none.  The default value is syslog.

       log_exit = boolean
             If true, sudo_logsrvd will log an event when  a  command  exits  or  is  terminated  by  a  signal.
             Defaults to false.

       log_format = string
             The  event log format.  Supported log formats are “sudo” for traditional sudo-style logs and “json”
             for JSON-format logs.  The JSON log entries contain the full contents of the accept,  reject,  exit
             and alert messages.  The default value is sudo.

   syslog
       The syslog section configures how events are logged via syslog(3).

       facility = string
             Syslog facility if syslog is being used for logging.  Defaults to authpriv.

             The  following  syslog  facilities  are supported: authpriv (if your OS supports it), auth, daemon,
             user, local0, local1, local2, local3, local4, local5, local6, and local7.

       accept_priority = string
             Syslog priority to use when the user is allowed to run a command and authentication is  successful.
             Defaults to notice.

             The  following  syslog  priorities  are  supported:  alert,  crit, debug, emerg, err, info, notice,
             warning, and none.  Setting it to a value of none will disable logging of successful commands.

       reject_priority = string
             Syslog priority to use when the user is not allowed to run a  command  or  when  authentication  is
             unsuccessful.  Defaults to alert.

             See accept_priority for the list of supported syslog priorities.

       alert_priority = string
             Syslog priority to use for event log alert messages received from the client.  Defaults to alert.

             See accept_priority for the list of supported syslog priorities.

       maxlen = number
             On  many  systems,  syslog(3)  has a relatively small log buffer.  IETF RFC 5424 states that syslog
             servers must support messages of at least 480 bytes and should support messages up to  2048  bytes.
             By default, sudo_logsrvd creates log messages up to 960 bytes which corresponds to the historic BSD
             syslog  implementation  which  used  a  1024  byte buffer to store the message, date, hostname, and
             program name.

             To prevent syslog messages from being truncated, sudo_logsrvd will split up sudo-style log messages
             that are larger than maxlen bytes.  When a message is split,  additional  parts  will  include  the
             string  “(command  continued)” after the user name and before the continued command line arguments.
             JSON-format log entries are never split and are not affected by maxlen.

       server_facility = string
             Syslog facility if syslog is being used for server warning messages.   See  above  for  a  list  of
             supported facilities.  Defaults to daemon

   logfile
       The logfile section consists of settings related to logging to a plain file (not syslog).

       path = string
             The  path  to  the  file-based  event  log.  This path must be fully-qualified and start with a ‘/’
             character.  The default value is /var/log/sudo.log.

       time_format = string
             The string used when formatting the date  and  time  for  file-based  event  logs.   Formatting  is
             performed  via the system's strftime(3) function so any escape sequences supported by that function
             will be expanded.  The default value is “%h %e %T” which produces dates like “Oct  3  07:15:24”  in
             the ‘C’ locale.
