NAME
       rsyncd.conf - configuration file for rsync in daemon mode

SYNOPSIS
       rsyncd.conf

DESCRIPTION
       The  rsyncd.conf  file is the runtime configuration file for rsync when
       run as an rsync daemon.

       The rsyncd.conf  file  controls  authentication,  access,  logging  and
       available modules.

FILE FORMAT
       The  file  consists of modules and parameters. A module begins with the
       name of the module in square brackets and continues until the next mod‐
       ule begins.  Modules contain parameters of the form name = value.

       The  file is line-based -- that is, each newline-terminated line repre‐
       sents either a comment, a module name or a parameter.

       Only the first equals sign in a parameter  is  significant.  Whitespace
       before  or  after the first equals sign is discarded. Leading, trailing
       and internal whitespace in module and parameter  names  is  irrelevant.
       Leading  and  trailing  whitespace  in  a parameter value is discarded.
       Internal whitespace within a parameter value is retained verbatim.

       Any line beginning with a hash (#) is ignored, as are lines  containing
       only  whitespace.  (If  a hash occurs after anything other than leading
       whitespace, it is considered a part of the line's content.)

       Any line ending in a \ is "continued" on the next line in the customary
       UNIX fashion.

       The  values  following  the  equals sign in parameters are all either a
       string (no quotes needed) or a boolean, which may be given  as  yes/no,
       0/1  or  true/false.  Case is not significant in boolean values, but is
       preserved in string values.

LAUNCHING THE RSYNC DAEMON
       The rsync daemon is launched  by  specifying  the  --daemon  option  to
       rsync.

       The  daemon must run with root privileges if you wish to use chroot, to
       bind to a port numbered under 1024 (as is the default 873), or  to  set
       file  ownership.   Otherwise,  it must just have permission to read and
       write the appropriate data, log, and lock files.

       You can launch it either via inetd, as a stand-alone daemon, or from an
       rsync  client  via a remote shell.  If run as a stand-alone daemon then
       just run the command "rsync --daemon" from a suitable startup script.

       When run via inetd you should add a line like this to /etc/services:

           rsync           873/tcp

       and a single line something like this to /etc/inetd.conf:

           rsync   stream  tcp     nowait  root   /usr/bin/rsync rsyncd --daemon

       Replace  "/usr/bin/rsync"  with  the  path  to  where  you  have  rsync
       installed  on your system.  You will then need to send inetd a HUP sig‐
       nal to tell it to reread its config file.

       Note that you should not send the rsync daemon a HUP signal to force it
       to reread the rsyncd.conf file. The file is re-read on each client con‐
       nection.

GLOBAL PARAMETERS
       The first parameters in the file (before a  [module]  header)  are  the
       global  parameters.  Rsync also allows for the use of a "[global]" mod‐
       ule name to indicate the start of one or more global-parameter sections
       (the name must be lower case).

       You  may  also  include any module parameters in the global part of the
       config file in which case the supplied value will override the  default
       for that parameter.

       You may use references to environment variables in the values of param‐
       eters.  String parameters will have %VAR% references expanded  as  late
       as  possible  (when  the string is first used in the program), allowing
       for the use of variables that rsync sets at connection  time,  such  as
       RSYNC_USER_NAME.   Non-string  parameters (such as true/false settings)
       are expanded when read from the config file.  If a  variable  does  not
       exist in the environment, or if a sequence of characters is not a valid
       reference (such as an un-paired percent sign), the raw  characters  are
       passed  through  unchanged.  This helps with backward compatibility and
       safety (e.g. expanding a non-existent %VAR% to an  empty  string  in  a
       path  could  result in a very unsafe path).  The safest way to insert a
       literal % into a value is to use %%.

       motd file
              This parameter allows you to specify a "message of the  day"  to
              display  to  clients on each connect. This usually contains site
              information and any legal notices. The default is no motd  file.
              This  can  be  overridden by the --dparam=motdfile=FILE command-
              line option when starting the daemon.

       pid file
              This parameter tells the rsync daemon to write its process ID to
              that  file.  The rsync keeps the file locked so that it can know
              when it is safe to overwrite an existing file.

              The filename can be overridden by the --dparam=pidfile=FILE com‐
              mand-line option when starting the daemon.

       port   You  can  override the default port the daemon will listen on by
              specifying this value (defaults to 873).  This is ignored if the
              daemon  is  being  run by inetd, and is superseded by the --port
              command-line option.

       address
              You can override the default IP address the daemon  will  listen
              on  by  specifying this value.  This is ignored if the daemon is
              being run by inetd, and is superseded by the --address  command-
              line option.

       socket options
              This  parameter  can  provide endless fun for people who like to
              tune their systems to the utmost degree. You can set  all  sorts
              of  socket options which may make transfers faster (or slower!).
              Read the man page for the setsockopt() system call  for  details
              on  some  of  the  options you may be able to set. By default no
              special socket options are set.   These  settings  can  also  be
              specified via the --sockopts command-line option.

       listen backlog
              You  can override the default backlog value when the daemon lis‐
              tens for connections.  It defaults to 5.

MODULE PARAMETERS
       After the global parameters you should define a number of modules, each
       module  exports  a  directory  tree  as  a  symbolic  name. Modules are
       exported by specifying a module name in square brackets  [module]  fol‐
       lowed  by  the parameters for that module.  The module name cannot con‐
       tain a slash or a closing square bracket.  If the name contains  white‐
       space, each internal sequence of whitespace will be changed into a sin‐
       gle space, while leading or  trailing  whitespace  will  be  discarded.
       Also,  the  name  cannot  be "global" as that exact name indicates that
       global parameters follow (see above).

       As with GLOBAL PARAMETERS, you may use references to environment  vari‐
       ables  in  the values of parameters.  See the GLOBAL PARAMETERS section
       for more details.

       comment
              This parameter specifies a description string that is  displayed
              next  to the module name when clients obtain a list of available
              modules. The default is no comment.

       path   This parameter specifies the directory in the daemon's  filesys‐
              tem  to  make  available  in this module.  You must specify this
              parameter for each module in rsyncd.conf.

              You may base the path's value off of an environment variable  by
              surrounding  the variable name with percent signs.  You can even
              reference a variable that is set by rsync  when  the  user  con‐
              nects.   For example, this would use the authorizing user's name
              in the path:

                  path = /home/%RSYNC_USER_NAME%

              It is fine if the path includes internal spaces -- they will  be
              retained  verbatim (which means that you shouldn't try to escape
              them).  If your final directory has a trailing space  (and  this
              is  somehow  not  something  you wish to fix), append a trailing
              slash to the path to avoid losing the trailing whitespace.

       use chroot
              If "use chroot" is true, the rsync daemon  will  chroot  to  the
              "path"  before starting the file transfer with the client.  This
              has the advantage of extra protection against possible implemen‐
              tation security holes, but it has the disadvantages of requiring
              super-user privileges, of not  being  able  to  follow  symbolic
              links  that are either absolute or outside of the new root path,
              and of complicating the preservation of users and groups by name
              (see below).

              As  an  additional  safety feature, you can specify a dot-dir in
              the module's "path" to  indicate  the  point  where  the  chroot
              should  occur.   This  allows  rsync  to  run in a chroot with a
              non-"/" path for the top of the transfer hierarchy.  Doing  this
              guards  against unintended library loading (since those absolute
              paths will not be inside the transfer hierarchy unless you  have
              used  an  unwise pathname), and lets you setup libraries for the
              chroot that are outside of the transfer.  For example,  specify‐
              ing  "/var/rsync/./module1"  will  chroot  to  the  "/var/rsync"
              directory and set the inside-chroot path to "/module1".  If  you
              had  omitted  the  dot-dir, the chroot would have used the whole
              path, and the inside-chroot path would have been "/".

              When both "use chroot" and "daemon chroot"  are  false,  OR  the
              inside-chroot  path  of "use chroot" is not "/", rsync will: (1)
              munge symlinks by default for security reasons (see "munge  sym‐
              links"  for  a  way to turn this off, but only if you trust your
              users), (2) substitute leading slashes in  absolute  paths  with
              the  module's path (so that options such as --backup-dir, --com‐
              pare-dest, etc. interpret an absolute path as rooted in the mod‐
              ule's  "path" dir), and (3) trim ".." path elements from args if
              rsync believes they would  escape  the  module  hierarchy.   The
              default for "use chroot" is true, and is the safer choice (espe‐
              cially if the module is not read-only).

              When this parameter is enabled and the "name converter"  parame‐
              ter  is  not  set,  the  "numeric ids" parameter will default to
              being enabled (disabling name lookups).  This means that if  you
              manually  setup name-lookup libraries in your chroot (instead of
              using  a  name  converter)  that  you  need  to  explicitly  set
              numeric ids = false for rsync to do name lookups.

              If you copy library resources into the module's chroot area, you
              should protect them through your OS's normal user/group  or  ACL
              settings  (to prevent the rsync module's user from being able to
              change them), and then  hide  them  from  the  user's  view  via
              "exclude"  (see  how in the discussion of that parameter).  How‐
              ever, it's easier and safer to setup a name converter.

       daemon chroot
              This parameter specifies a path to which the daemon will  chroot
              before  beginning  communication with clients. Module paths (and
              any "use chroot" settings) will then be  related  to  this  one.
              This lets you choose if you want the whole daemon to be chrooted
              (with this setting), just the transfers  to  be  chrooted  (with
              "use  chroot"),  or both.  Keep in mind that the "daemon chroot"
              area may need various OS/lib/etc files installed  to  allow  the
              daemon  to  function.   By  default  the daemon runs without any
              chrooting.

       proxy protocol
              When this parameter is enabled, all  incoming  connections  must
              start  with  a V1 or V2 proxy protocol header.  If the header is
              not found, the connection is closed.

              Setting this to true requires a proxy server to  forward  source
              IP information to rsync, allowing you to log proper IP/host info
              and make use of client-oriented IP restrictions.  The default of
              false  means  that  the  IP  information comes directly from the
              socket's metadata.  If rsync is not behind a proxy, this  should
              be disabled.

              CAUTION: using this option can be dangerous if you do not ensure
              that only the proxy is allowed to connect to the rsync port.  If
              any non-proxied connections are allowed through, the client will
              be able to use a modified rsync to spoof any remote  IP  address
              that  they  desire.  You can lock this down using something like
              iptables -uid-owner root rules (for  strict  localhost  access),
              various  firewall  rules, or you can require password authoriza‐
              tion so that any spoofing by users will not grant extra access.

              This setting is global.  If you need  some  modules  to  require
              this  and not others, then you will need to setup multiple rsync
              daemon processes on different ports.

       name converter
              This parameter lets you specify a program that will  be  run  by
              the  rsync daemon to do user & group conversions between names &
              ids.  This script is started prior to any  chroot  being  setup,
              and  runs  as  the daemon user (not the transfer user).  You can
              specify a fully qualified pathname or a program name that is  on
              the $PATH.

              The  program can be used to do normal user & group lookups with‐
              out having to put any extra files into the chroot  area  of  the
              module or you can do customized conversions.

              The  nameconvert  program  has  access to all of the environment
              variables that are described in the  section  on  pre-xfer exec.
              This  is  useful  if  you want to customize the conversion using
              information about the module and/or the copy request.

              There is a sample python script in the support dir named  "name‐
              convert"  that implements the normal user & group lookups.  Feel
              free to customize it or just use it as documentation  to  imple‐
              ment your own.

       numeric ids
              Enabling this parameter disables the mapping of users and groups
              by name for the current daemon module.  This prevents the daemon
              from  trying  to load any user/group-related files or libraries.
              This enabling makes the transfer behave as  if  the  client  had
              passed  the --numeric-ids command-line option.  By default, this
              parameter is enabled for chroot modules and  disabled  for  non-
              chroot  modules.   Also  keep  in mind that uid/gid preservation
              requires the module to be running as root  (see  "uid")  or  for
              "fake super" to be configured.

              A  chroot-enabled  module  should not have this parameter set to
              false unless you're using a "name converter" program  or  you've
              taken  steps  to  ensure  that  the  module  has  the  necessary
              resources it needs to translate names and that it is not  possi‐
              ble for a user to change those resources.

       munge symlinks
              This  parameter  tells  rsync to modify all symlinks in the same
              way as  the  (non-daemon-affecting)  --munge-links  command-line
              option  (using a method described below).  This should help pro‐
              tect your files from user trickery when your  daemon  module  is
              writable.   The default is disabled when "use chroot" is on with
              an inside-chroot path of "/", OR if "daemon chroot" is on,  oth‐
              erwise it is enabled.

              If you disable this parameter on a daemon that is not read-only,
              there are tricks that a user can play with uploaded symlinks  to
              access  daemon-excluded  items (if your module has any), and, if
              "use chroot" is off, rsync can even be tricked into  showing  or
              changing  data that is outside the module's path (as access-per‐
              missions allow).

              The way rsync disables the use of symlinks is to prefix each one
              with the string "/rsyncd-munged/".  This prevents the links from
              being used as long as that directory does not exist.  When  this
              parameter is enabled, rsync will refuse to run if that path is a
              directory or a symlink to a directory.  When  using  the  "munge
              symlinks"  parameter  in a chroot area that has an inside-chroot
              path of "/", you should add  "/rsyncd-munged/"  to  the  exclude
              setting for the module so that a user can't try to create it.

              Note:   rsync  makes  no attempt to verify that any pre-existing
              symlinks in the module's hierarchy are as safe as you want  them
              to  be  (unless,  of course, it just copied in the whole hierar‐
              chy).  If you setup an rsync daemon on a new area or locally add
              symlinks,  you  can  manually  protect  your symlinks from being
              abused by prefixing "/rsyncd-munged/" to the start of every sym‐
              link's  value.   There is a perl script in the support directory
              of the source code named "munge-symlinks" that can  be  used  to
              add or remove this prefix from your symlinks.

              When  this  parameter  is disabled on a writable module and "use
              chroot" is off (or the inside-chroot path is not "/"),  incoming
              symlinks  will be modified to drop a leading slash and to remove
              ".." path elements that rsync believes will allow a  symlink  to
              escape  the  module's  hierarchy.  There are tricky ways to work
              around this, though, so you had better trust your users  if  you
              choose this combination of parameters.

       charset
              This  specifies  the name of the character set in which the mod‐
              ule's filenames are stored.   If  the  client  uses  an  --iconv
              option, the daemon will use the value of the "charset" parameter
              regardless of the character  set  the  client  actually  passed.
              This allows the daemon to support charset conversion in a chroot
              module without extra files in the chroot area, and also  ensures
              that  name-translation  is  done in a consistent manner.  If the
              "charset" parameter is not set, the --iconv option  is  refused,
              just as if "iconv" had been specified via "refuse options".

              If  you wish to force users to always use --iconv for a particu‐
              lar module, add "no-iconv" to the  "refuse  options"  parameter.
              Keep  in  mind  that this will restrict access to your module to
              very new rsync clients.

       max connections
              This parameter allows you  to  specify  the  maximum  number  of
              simultaneous connections you will allow.  Any clients connecting
              when the maximum has been reached will receive a message telling
              them  to  try later.  The default is 0, which means no limit.  A
              negative value disables the module.  See also  the  "lock  file"
              parameter.

       log file
              When  the "log file" parameter is set to a non-empty string, the
              rsync daemon will log messages to the indicated file rather than
              using  syslog.   This is particularly useful on systems (such as
              AIX) where syslog() doesn't work  for  chrooted  programs.   The
              file  is  opened  before  chroot()  is called, allowing it to be
              placed outside the transfer.  If this value is set on a per-mod‐
              ule basis instead of globally, the global log will still contain
              any authorization failures or config-file error messages.

              If the daemon fails to open the specified  file,  it  will  fall
              back  to  using  syslog  and  output an error about the failure.
              (Note that the failure to open the specified log file used to be
              a fatal error.)

              This  setting  can be overridden by using the --log-file=FILE or
              --dparam=logfile=FILE command-line options.   The  former  over‐
              rides  all  the log-file parameters of the daemon and all module
              settings.  The latter sets the daemon's log file and the default
              for  all the modules, which still allows modules to override the
              default setting.

       syslog facility
              This parameter allows you to specify the syslog facility name to
              use when logging messages from the rsync daemon. You may use any
              standard syslog facility name which is defined on  your  system.
              Common  names  are auth, authpriv, cron, daemon, ftp, kern, lpr,
              mail,  news,  security,  syslog,  user,  uucp,  local0,  local1,
              local2,  local3, local4, local5, local6 and local7.  The default
              is daemon.  This setting has no effect if the "log file" setting
              is  a  non-empty string (either set in the per-modules settings,
              or inherited from the global settings).

       syslog tag
              This parameter allows you to specify the syslog tag to use  when
              logging messages from the rsync daemon. The default is "rsyncd".
              This setting has no effect if the "log file" setting is  a  non-
              empty  string (either set in the per-modules settings, or inher‐
              ited from the global settings).

              For example, if you wanted each authenticated user's name to  be
              included in the syslog tag, you could do something like this:

                  syslog tag = rsyncd.%RSYNC_USER_NAME%

       max verbosity
              This  parameter allows you to control the maximum amount of ver‐
              bose information that you'll allow the daemon to generate (since
              the information goes into the log file). The default is 1, which
              allows the client to request one level of verbosity.

              This also affects the user's ability to request higher levels of
              --info and --debug logging.  If the max value is 2, then no info
              and/or debug value that is higher than what would be set by  -vv
              will  be  honored by the daemon in its logging.  To see how high
              of a verbosity  level  you  need  to  accept  for  a  particular
              info/debug     level,    refer    to    rsync --info=help    and
              rsync --debug=help.  For instance, it takes max-verbosity  4  to
              be able to output debug TIME2 and FLIST3.

       lock file
              This  parameter  specifies  the  file to use to support the "max
              connections" parameter. The rsync daemon uses record locking  on
              this  file  to  ensure  that  the  max  connections limit is not
              exceeded for the modules sharing the lock file.  The default  is
              /var/run/rsyncd.lock.

       read only
              This parameter determines whether clients will be able to upload
              files or not. If "read only" is true then any attempted  uploads
              will fail. If "read only" is false then uploads will be possible
              if file permissions on the daemon side allow them.  The  default
              is for all modules to be read only.

              Note  that  "auth users" can override this setting on a per-user
              basis.

       write only
              This parameter determines whether clients will be able to  down‐
              load  files  or  not. If "write only" is true then any attempted
              downloads will fail. If "write only"  is  false  then  downloads
              will  be  possible  if file permissions on the daemon side allow
              them.  The default is for this parameter to be disabled.

              Helpful hint: you probably want to  specify  "refuse  options  =
              delete" for a write-only module.

       open noatime
              When  set to True, this parameter tells the rsync daemon to open
              files with the O_NOATIME flag (on systems that  support  it)  to
              avoid  changing  the  access  time  of  the files that are being
              transferred.  If your OS does not  support  the  O_NOATIME  flag
              then  rsync  will  silently  ignore this option.  Note also that
              some filesystems are mounted to avoid updating the atime on read
              access even without the O_NOATIME flag being set.

              When  set  to  False,  this parameters ensures that files on the
              server are not opened with O_NOATIME.

              When set to Unset (the default) the user  controls  the  setting
              via --open-noatime.

       list   This parameter determines whether this module is listed when the
              client asks for a listing of available modules.  In addition, if
              this is false, the daemon will pretend the module does not exist
              when a client denied by "hosts allow" or "hosts  deny"  attempts
              to  access  it.   Realize  that  if "reverse lookup" is disabled
              globally but enabled  for  the  module,  the  resulting  reverse
              lookup  to  a potentially client-controlled DNS server may still
              reveal to the client  that  it  hit  an  existing  module.   The
              default is for modules to be listable.

       uid    This  parameter  specifies  the  user  name or user ID that file
              transfers to and from that module should take place as when  the
              daemon was run as root.  In combination with the "gid" parameter
              this determines what file permissions are available. The default
              when  run  by a super-user is to switch to the system's "nobody"
              user.  The default for a non-super-user is to not try to  change
              the user.  See also the "gid" parameter.

              The  RSYNC_USER_NAME environment variable may be used to request
              that rsync run as the authorizing user.   For  example,  if  you
              want  a  rsync to run as the same user that was received for the
              rsync authentication, this setup is useful:

                  uid = %RSYNC_USER_NAME%
                  gid = *

       gid    This parameter specifies one or more group names/IDs  that  will
              be  used  when  accessing the module.  The first one will be the
              default group, and any extra ones be set as supplemental groups.
              You  may  also specify a "*" as the first gid in the list, which
              will be replaced by all the normal  groups  for  the  transfer's
              user  (see  "uid").   The default when run by a super-user is to
              switch to your OS's "nobody" (or perhaps "nogroup")  group  with
              no other supplementary groups.  The default for a non-super-user
              is to not change any group attributes (and indeed, your  OS  may
              not  allow  a  non-super-user  to try to change their group set‐
              tings).

              The specified list is normally split into tokens based on spaces
              and  commas.  However, if the list starts with a comma, then the
              list is only split on commas, which allows a group name to  con‐
              tain a space.  In either case any leading and/or trailing white‐
              space is removed from the tokens and empty tokens are ignored.

       daemon uid
              This parameter specifies a uid under which the daemon will  run.
              The  daemon  usually  runs  as  user root, and when this is left
              unset the user is left unchanged. See also the "uid" parameter.

       daemon gid
              This parameter specifies a gid under which the daemon will  run.
              The  daemon  usually  runs  as group root, and when this is left
              unset, the group is left unchanged. See also the  "gid"  parame‐
              ter.

       fake super
              Setting  "fake  super = yes" for a module causes the daemon side
              to behave as if the --fake-super command-line  option  had  been
              specified.   This  allows  the  full  attributes of a file to be
              stored without having to have the  daemon  actually  running  as
              root.

       filter The  daemon  has its own filter chain that determines what files
              it will let the client access.  This chain is not  sent  to  the
              client  and  is  independent  of any filters the client may have
              specified.  Files excluded by the daemon filter  chain  (daemon-
              excluded  files) are treated as non-existent if the client tries
              to pull them, are skipped with an error message  if  the  client
              tries  to  push  them  (triggering  exit code 23), and are never
              deleted from the module.  You can use daemon filters to  prevent
              clients  from  downloading or tampering with private administra‐
              tive files, such as files you may add to  support  uid/gid  name
              translations.

              The  daemon  filter  chain  is built from the "filter", "include
              from", "include", "exclude from", and "exclude"  parameters,  in
              that  order  of priority.  Anchored patterns are anchored at the
              root of the module.  To prevent access to an entire subtree, for
              example,  "/secret", you must exclude everything in the subtree;
              the easiest way to do this is with a  triple-star  pattern  like
              "/secret/***".

              The  "filter"  parameter  takes a space-separated list of daemon
              filter rules, though it is smart enough to know not to  split  a
              token  at  an  internal space in a rule (e.g. "- /foo - /bar" is
              parsed as two rules).  You may specify one  or  more  merge-file
              rules  using the normal syntax.  Only one "filter" parameter can
              apply to a given module in the config file, so put all the rules
              you  want in a single parameter.  Note that per-directory merge-
              file rules do not provide as much protection  as  global  rules,
              but  they  can  be  used  to  make --delete work better during a
              client  download  operation  if  the  per-dir  merge  files  are
              included  in  the  transfer and the client requests that they be
              used.

       exclude
              This parameter takes a space-separated list  of  daemon  exclude
              patterns.   As with the client --exclude option, patterns can be
              qualified   with   "-"   or   "+"   to    explicitly    indicate
              exclude/include.   Only  one  "exclude" parameter can apply to a
              given module.  See the "filter" parameter for a  description  of
              how excluded files affect the daemon.

       include
              Use an "include" to override the effects of the "exclude" param‐
              eter.  Only one "include" parameter can apply to a given module.
              See  the  "filter"  parameter  for a description of how excluded
              files affect the daemon.

       exclude from
              This parameter specifies the name of a file on the  daemon  that
              contains  daemon  exclude  patterns,  one  per  line.   Only one
              "exclude from" parameter can apply to a  given  module;  if  you
              have  multiple  exclude-from  files,  you  can specify them as a
              merge file in the "filter" parameter.  See the "filter"  parame‐
              ter for a description of how excluded files affect the daemon.

       include from
              Analogue  of  "exclude  from"  for a file of daemon include pat‐
              terns.  Only one "include from" parameter can apply to  a  given
              module.   See  the  "filter"  parameter for a description of how
              excluded files affect the daemon.

       incoming chmod
              This parameter allows you to specify a  set  of  comma-separated
              chmod  strings  that will affect the permissions of all incoming
              files (files that are being  received  by  the  daemon).   These
              changes happen after all other permission calculations, and this
              will even override destination-default and/or  existing  permis‐
              sions  when  the  client  does  not  specify  --perms.   See the
              description of the --chmod rsync option and the chmod(1) manpage
              for information on the format of this string.

       outgoing chmod
              This  parameter  allows  you to specify a set of comma-separated
              chmod strings that will affect the permissions of  all  outgoing
              files  (files  that  are being sent out from the daemon).  These
              changes happen first, making the sent permissions appear  to  be
              different  than  those  stored  in  the  filesystem itself.  For
              instance, you could  disable  group  write  permissions  on  the
              server  while having it appear to be on to the clients.  See the
              description of the --chmod rsync option and the chmod(1) manpage
              for information on the format of this string.

       auth users
              This  parameter specifies a comma and/or space-separated list of
              authorization rules.  In its simplest form, you list  the  user‐
              names  that will be allowed to connect to this module. The user‐
              names do not need to exist on the local system.  The  rules  may
              contain  shell  wildcard characters that will be matched against
              the username provided by the client for authentication. If "auth
              users"  is  set  then  the client will be challenged to supply a
              username and password to connect  to  the  module.  A  challenge
              response  authentication protocol is used for this exchange. The
              plain text usernames and passwords are stored in the file speci‐
              fied  by  the  "secrets  file" parameter. The default is for all
              users to be able to connect without a password (this  is  called
              "anonymous rsync").

              In  addition  to  username  matching,  you can specify groupname
              matching via a '@' prefix.  When using groupname  matching,  the
              authenticating username must be a real user on the system, or it
              will be assumed to be a member of no groups.  For example, spec‐
              ifying  "@rsync" will match the authenticating user if the named
              user is a member of the rsync group.

              Finally, options may  be  specified  after  a  colon  (:).   The
              options allow you to "deny" a user or a group, set the access to
              "ro" (read-only), or set the access to "rw" (read/write).   Set‐
              ting  an auth-rule-specific ro/rw setting overrides the module's
              "read only" setting.

              Be sure to put the rules in  the  order  you  want  them  to  be
              matched,  because  the checking stops at the first matching user
              or group, and that is the only auth that is checked.  For  exam‐
              ple:

                  auth users = joe:deny @guest:deny admin:rw @rsync:ro susan joe sam

              In  the  above  rule,  user  joe will be denied access no matter
              what.  Any user that is in the  group  "guest"  is  also  denied
              access.   The  user  "admin" gets access in read/write mode, but
              only if the admin user is not  in  group  "guest"  (because  the
              admin  user-matching  rule would never be reached if the user is
              in group "guest").  Any other user who is in group "rsync"  will
              get  read-only  access.   Finally, users susan, joe, and sam get
              the ro/rw setting of the module, but only  if  the  user  didn't
              match an earlier group-matching rule.

              If  you need to specify a user or group name with a space in it,
              start your list with a comma to indicate that  the  list  should
              only  be split on commas (though leading and trailing whitespace
              will also be removed, and empty entries are just ignored).   For
              example:

                  auth users = , joe:deny, @Some Group:deny, admin:rw, @RO Group:ro

              See  the  description  of  the secrets file for how you can have
              per-user passwords as well  as  per-group  passwords.   It  also
              explains  how  a user can authenticate using their user password
              or (when applicable) a group password, depending on what rule is
              being authenticated.

              See also the section entitled "USING RSYNC-DAEMON FEATURES VIA A
              REMOTE SHELL CONNECTION" in rsync(1) for information on how han‐
              dle  an rsyncd.conf-level username that differs from the remote-
              shell-level username when using a remote shell to connect to  an
              rsync daemon.

       secrets file
              This  parameter  specifies  the name of a file that contains the
              username:password  and/or  @groupname:password  pairs  used  for
              authenticating  this  module. This file is only consulted if the
              "auth users" parameter is specified.  The file is line-based and
              contains  one  name:password pair per line.  Any line has a hash
              (#) as the very first character on the line is considered a com‐
              ment  and  is skipped.  The passwords can contain any characters
              but be warned that many operating systems limit  the  length  of
              passwords  that  can be typed at the client end, so you may find
              that passwords longer than 8 characters don't work.

              The use of group-specific lines are only relevant when the  mod‐
              ule  is  being  authorized  using  a matching "@groupname" rule.
              When that happens, the user can be authorized via  either  their
              "username:password"  line  or the "@groupname:password" line for
              the group that triggered the authentication.

              It is up to you what  kind  of  password  entries  you  want  to
              include,  either users, groups, or both.  The use of group rules
              in "auth users" does not require that you specify a group  pass‐
              word if you do not want to use shared passwords.

              There  is  no default for the "secrets file" parameter, you must
              choose a name (such as /etc/rsyncd.secrets).  The file must nor‐
              mally  not  be  readable by "other"; see "strict modes".  If the
              file is not found or is rejected, no logins for  a  "user  auth"
              module will be possible.

       strict modes
              This  parameter determines whether or not the permissions on the
              secrets file will be checked.  If "strict modes" is  true,  then
              the  secrets file must not be readable by any user ID other than
              the one that the rsync daemon  is  running  under.   If  "strict
              modes"  is  false,  the  check is not performed.  The default is
              true.  This parameter was added to accommodate rsync running  on
              the Windows operating system.

       hosts allow
              This  parameter  allows  you  to specify a list of comma- and/or
              whitespace-separated patterns that are matched  against  a  con‐
              necting  client's  hostname and IP address.  If none of the pat‐
              terns match, then the connection is rejected.

              Each pattern can be in one of six forms:

              o      a dotted decimal IPv4 address of the form a.b.c.d, or  an
                     IPv6  address  of the form a:b:c::d:e:f. In this case the
                     incoming machine's IP address must match exactly.

              o      an address/mask in the form ipaddr/n where ipaddr is  the
                     IP  address  and  n is the number of one bits in the net‐
                     mask.  All IP addresses which match the masked IP address
                     will be allowed in.

              o      an  address/mask in the form ipaddr/maskaddr where ipaddr
                     is the IP address and maskaddr is the netmask  in  dotted
                     decimal  notation  for  IPv4,  or  similar for IPv6, e.g.
                     ffff:ffff:ffff:ffff:: instead of /64.  All  IP  addresses
                     which match the masked IP address will be allowed in.

              o      a  hostname  pattern  using wildcards. If the hostname of
                     the connecting IP (as determined  by  a  reverse  lookup)
                     matches the wildcarded name (using the same rules as nor‐
                     mal unix filename matching), the client  is  allowed  in.
                     This  only  works  if  "reverse  lookup"  is enabled (the
                     default).

              o      a hostname. A  plain  hostname  is  matched  against  the
                     reverse  DNS of the connecting IP (if "reverse lookup" is
                     enabled), and/or the IP of the given hostname is  matched
                     against   the  connecting  IP  (if  "forward  lookup"  is
                     enabled, as it is by default).  Any match will be allowed
                     in.

              o      an  '@'  followed by a netgroup name, which will match if
                     the reverse DNS of the connecting IP is in the  specified
                     netgroup.

              Note  IPv6  link-local addresses can have a scope in the address
              specification:

                  fe80::1%link1
                  fe80::%link1/64
                  fe80::%link1/ffff:ffff:ffff:ffff::

              You can also combine "hosts allow" with "hosts deny" as a way to
              add  exceptions  to  your  deny  list.  When both parameters are
              specified, the "hosts allow" parameter is checked  first  and  a
              match  results  in  the  client  being  able to connect.  A non-
              allowed host is then matched against the "hosts  deny"  list  to
              see if it should be rejected.  A host that does not match either
              list is allowed to connect.

              The default is no "hosts allow" parameter, which means all hosts
              can connect.

       hosts deny
              This  parameter  allows  you  to specify a list of comma- and/or
              whitespace-separated patterns that are matched  against  a  con‐
              necting  clients hostname and IP address. If the pattern matches
              then the connection is rejected. See the "hosts allow" parameter
              for more information.

              The  default is no "hosts deny" parameter, which means all hosts
              can connect.

       reverse lookup
              Controls whether the daemon performs a  reverse  lookup  on  the
              client's IP address to determine its hostname, which is used for
              "hosts allow" & "hosts deny" checks and  the  "%h"  log  escape.
              This  is  enabled  by default, but you may wish to disable it to
              save time if you know  the  lookup  will  not  return  a  useful
              result,  in  which  case  the daemon will use the name "UNDETER‐
              MINED" instead.

              If this parameter is enabled globally (even by  default),  rsync
              performs  the  lookup as soon as a client connects, so disabling
              it for a module will not avoid the lookup.  Thus,  you  probably
              want  to disable it globally and then enable it for modules that
              need the information.

       forward lookup
              Controls whether the daemon performs a  forward  lookup  on  any
              hostname  specified  in an hosts allow/deny setting.  By default
              this is enabled, allowing the use of an explicit  hostname  that
              would not be returned by reverse DNS of the connecting IP.

       ignore errors
              This  parameter  tells rsyncd to ignore I/O errors on the daemon
              when deciding whether to run the delete phase of  the  transfer.
              Normally  rsync  skips  the --delete step if any I/O errors have
              occurred in order to prevent disastrous deletion due to a tempo‐
              rary  resource  shortage  or other I/O error. In some cases this
              test is counter productive so you can use this parameter to turn
              off this behavior.

       ignore nonreadable
              This  tells the rsync daemon to completely ignore files that are
              not readable by the user. This is  useful  for  public  archives
              that may have some non-readable files among the directories, and
              the sysadmin doesn't want those files to be seen at all.

       transfer logging
              This parameter enables per-file logging of downloads and uploads
              in  a  format somewhat similar to that used by ftp daemons.  The
              daemon always logs the transfer at the end, so if a transfer  is
              aborted, no mention will be made in the log file.

              If  you  want  to  customize the log lines, see the "log format"
              parameter.

       log format
              This parameter allows you to specify the format used for logging
              file  transfers when transfer logging is enabled.  The format is
              a  text  string  containing  embedded  single-character   escape
              sequences  prefixed  with  a percent (%) character.  An optional
              numeric field width may also be specified  between  the  percent
              and  the  escape  letter (e.g.  "%-50n %8l %07p").  In addition,
              one or more apostrophes may be specified prior  to  a  numerical
              escape  to indicate that the numerical value should be made more
              human-readable.  The 3 supported levels are the same as for  the
              --human-readable  command-line option, though the default is for
              human-readability to be off.  Each  added  apostrophe  increases
              the level (e.g. "%''l %'b %f").

              The  default  log  format  is  "%o %h [%a] %m (%u) %f %l", and a
              "%t [%p]" is always prefixed when using the "log  file"  parame‐
              ter.  (A perl script that will summarize this default log format
              is included in the rsync source code distribution in  the  "sup‐
              port" subdirectory: rsyncstats.)

              The single-character escapes that are understood are as follows:

              o      %a the remote IP address (only available for a daemon)

              o      %b the number of bytes actually transferred

              o      %B the permission bits of the file (e.g. rwxrwxrwt)

              o      %c the total size of the block checksums received for the
                     basis file (only when sending)

              o      %C the full-file checksum if it is known  for  the  file.
                     For  older  rsync  protocols/versions,  the  checksum was
                     salted, and is thus not a useful value (and is  not  dis‐
                     played when that is the case). For the checksum to output
                     for a file, either the  --checksum  option  must  be  in-
                     effect  or  the file must have been transferred without a
                     salted checksum being used.   See  the  --checksum-choice
                     option for a way to choose the algorithm.

              o      %f the filename (long form on sender; no trailing "/")

              o      %G the gid of the file (decimal) or "DEFAULT"

              o      %h the remote host name (only available for a daemon)

              o      %i an itemized list of what is being updated

              o      %l the length of the file in bytes

              o      %L  the  string "-> SYMLINK", "=> HARDLINK", or "" (where
                     SYMLINK or HARDLINK is a filename)

              o      %m the module name

              o      %M the last-modified time of the file

              o      %n the filename (short form; trailing "/" on dir)

              o      %o the operation, which is "send", "recv", or "del." (the
                     latter includes the trailing period)

              o      %p the process ID of this rsync session

              o      %P the module path

              o      %t the current date time

              o      %u the authenticated username or an empty string

              o      %U the uid of the file (decimal)

              For  a list of what the characters mean that are output by "%i",
              see the --itemize-changes option in the rsync manpage.

              Note that some of the logged output changes  when  talking  with
              older  rsync  versions.   For  instance, deleted files were only
              output as verbose messages prior to rsync 2.6.4.

       timeout
              This parameter allows you to override the clients choice for I/O
              timeout  for  this  module.  Using this parameter you can ensure
              that rsync won't wait on a dead client forever. The  timeout  is
              specified  in  seconds.  A value of zero means no timeout and is
              the default. A good choice for anonymous rsync  daemons  may  be
              600 (giving a 10 minute timeout).

       refuse options
              This  parameter  allows you to specify a space-separated list of
              rsync command-line options that will be refused  by  your  rsync
              daemon.   You  may  specify the full option name, its one-letter
              abbreviation,  or  a  wild-card  string  that  matches  multiple
              options. Beginning in 3.2.0, you can also negate a match term by
              starting it with a "!".

              When an option is refused, the daemon prints  an  error  message
              and exits.

              For example, this would refuse --checksum (-c) and all the vari‐
              ous delete options:

                  refuse options = c delete

              The reason the above refuses all  delete  options  is  that  the
              options  imply  --delete,  and  implied options are refused just
              like explicit options.

              The use of a negated match allows you to fine-tune your refusals
              after a wild-card, such as this:

                  refuse options = delete-* !delete-during

              Negated matching can also turn your list of refused options into
              a list of accepted options. To do this, begin the  list  with  a
              "*" (to refuse all options) and then specify one or more negated
              matches to accept.  For example:

                  refuse options = * !a !v !compress*

              Don't worry that the "*" will refuse certain vital options  such
              as  --dry-run,  --server, --no-iconv, --protect-args, etc. These
              important options are not matched by wild-card, so they must  be
              overridden by their exact name.  For instance, if you're forcing
              iconv transfers you could use something like this:

                  refuse options = * no-iconv !a !v

              As an additional aid (beginning in 3.2.0), refusing (or "!refus‐
              ing")  the "a" or "archive"  option also affects all the options
              that the --archive option implies (-rdlptgoD), but only  if  the
              option   is  matched  explicitly  (not using a wildcard). If you
              want to do something tricky, you can  use  "archive*"  to  avoid
              this  side-effect,  but keep in mind that no normal rsync client
              ever sends the actual archive option to the server.

              As an additional safety feature, the refusal  of  "delete"  also
              refuses  remove-source-files  when  the daemon is the sender; if
              you  want  the  latter  without  the  former,   instead   refuse
              "delete-*"  as that refuses all the delete modes without affect‐
              ing --remove-source-files.  (Keep  in  mind  that  the  client's
              --delete option typically results in --delete-during.)

              When  un-refusing  delete  options,  you  should  either specify
              "!delete*" (to accept all delete options) or specify  a  limited
              set that includes "delete", such as:

                  refuse options = * !a !delete !delete-during

              ...  whereas  this  accepts  any  delete option except --delete-
              after:

                  refuse options = * !a !delete* delete-after

              A note on refusing "compress" -- it is better to set  the  "dont
              compress" daemon parameter to "*" because that disables compres‐
              sion silently instead of returning  an  error  that  forces  the
              client to remove the -z option.

              If you are un-refusing the compress option, you probably want to
              match "!compress*" so that you also accept the  --compress-level
              option.

              Note  that the "write-devices" option is refused by default, but
              can be explicitly accepted with "!write-devices".   The  options
              "log-file" and "log-file-format" are forcibly refused and cannot
              be accepted.

              Here are all the options that are not matched by wild-cards:

              o      --server: Required for rsync to even work.

              o      --rsh, -e: Required to convey compatibility flags to  the
                     server.

              o      --out-format:  This is required to convey output behavior
                     to a remote receiver.  While rsync passes the older alias
                     --log-format  for  compatibility  reasons,  this  options
                     should not be confused with --log-file-format.

              o      --sender: Use "write only" parameter instead of  refusing
                     this.

              o      --dry-run, -n: Who would want to disable this?

              o      --protect-args, -s: This actually makes transfers safer.

              o      --from0,  -0:  Makes  it easier to accept/refuse --files-
                     from without affecting this helpful modifier.

              o      --iconv: This is auto-disabled based on "charset" parame‐
                     ter.

              o      --no-iconv: Most transfers use this option.

              o      --checksum-seed: Is a fairly rare, safe option.

              o      --write-devices: Is non-wild but also auto-disabled.

       dont compress
              This  parameter allows you to select filenames based on wildcard
              patterns that should not be compressed when pulling  files  from
              the  daemon (no analogous parameter exists to govern the pushing
              of files to a daemon).  Compression can be expensive in terms of
              CPU  usage,  so  it is usually good to not try to compress files
              that won't compress well, such as already compressed files.

              The "dont compress" parameter takes a  space-separated  list  of
              case-insensitive wildcard patterns. Any source filename matching
              one of the patterns will be compressed  as  little  as  possible
              during  the transfer.  If the compression algorithm has an "off"
              level (such as zlib/zlibx) then no compression occurs for  those
              files.  Other algorithms have the level minimized to reduces the
              CPU usage as much as possible.

              See the --skip-compress parameter in the  rsync(1)  manpage  for
              the  list  of  file suffixes that are not compressed by default.
              Specifying a value for the "dont compress" parameter changes the
              default when the daemon is the sender.

       early exec, pre-xfer exec, post-xfer exec
              You  may  specify a command to be run in the early stages of the
              connection, or right before and/or after the transfer.   If  the
              early exec  or  pre-xfer exec command returns an error code, the
              transfer is aborted before it begins.  Any output from the  pre-
              xfer exec command on stdout (up to several KB) will be displayed
              to the user when aborting, but is not displayed  if  the  script
              returns success.  The other programs cannot send any text to the
              user.  All output except for the pre-xfer exec  stdout  goes  to
              the  corresponding  daemon's  stdout/stderr,  which is typically
              discarded.  See the --no-detatch option for a  way  to  see  the
              daemon's output, which can assist with debugging.

              Note  that  the  early exec  command runs before any part of the
              transfer request is known except  for  the  module  name.   This
              helper  script can be used to setup a disk mount or decrypt some
              data into a module dir, but you may need to  use  lock file  and
              max connections  to  avoid  concurrency  issues.   If the client
              rsync specified the --early-input=FILE option, it can send up to
              about  5K  of  data to the stdin of the early script.  The stdin
              will otherwise be empty.

              Note that the post-xfer exec command is still run even if one of
              the  other scripts returns an error code. The pre-xfer exec com‐
              mand will not be run, however, if the early exec command fails.

              The following environment variables will be set, though some are
              specific to the pre-xfer or the post-xfer environment:

              o      RSYNC_MODULE_NAME: The name of the module being accessed.

              o      RSYNC_MODULE_PATH: The path configured for the module.

              o      RSYNC_HOST_ADDR: The accessing host's IP address.

              o      RSYNC_HOST_NAME: The accessing host's name.

              o      RSYNC_USER_NAME:  The  accessing user's name (empty if no
                     user).

              o      RSYNC_PID: A unique number for this transfer.

              o      RSYNC_REQUEST: (pre-xfer only) The module/path info spec‐
                     ified by the user.  Note that the user can specify multi‐
                     ple source files, so the request can  be  something  like
                     "mod/path1 mod/path2", etc.

              o      RSYNC_ARG#: (pre-xfer only) The pre-request arguments are
                     set  in  these  numbered  values.  RSYNC_ARG0  is  always
                     "rsyncd",  followed  by  the  options  that  were used in
                     RSYNC_ARG1, and so on.  There will  be  a  value  of  "."
                     indicating  that  the  options are done and the path args
                     are beginning -- these  contain  similar  information  to
                     RSYNC_REQUEST,  but  with values separated and the module
                     name stripped off.

              o      RSYNC_EXIT_STATUS: (post-xfer  only)  the  server  side's
                     exit value.  This will be 0 for a successful run, a posi‐
                     tive value for an error that the server generated,  or  a
                     -1  if rsync failed to exit properly.  Note that an error
                     that occurs on the client side  does  not  currently  get
                     sent  to  the  server side, so this is not the final exit
                     status for the whole transfer.

              o      RSYNC_RAW_STATUS: (post-xfer only)  the  raw  exit  value
                     from waitpid().

              Even  though  the  commands  can be associated with a particular
              module, they are run using the  permissions  of  the  user  that
              started  the  daemon  (not the module's uid/gid setting) without
              any chroot restrictions.

              These settings honor 2 environment variables: use RSYNC_SHELL to
              set  a  shell  to  use when running the command (which otherwise
              uses   your   system()   call's   default   shell),   and    use
              RSYNC_NO_XFER_EXEC to disable both options completely.

CONFIG DIRECTIVES
       There are currently two config directives available that allow a config
       file to incorporate the contents of other files:  &include and  &merge.
       Both allow a reference to either a file or a directory.  They differ in
       how segregated the file's contents are considered to be.

       The &include directive treats each file as more distinct, with each one
       inheriting  the  defaults  of  the  parent file, starting the parameter
       parsing as globals/defaults, and leaving the defaults unchanged for the
       parsing of the rest of the parent file.

       The  &merge directive, on the other hand, treats the file's contents as
       if it were simply inserted in place of the directive, and thus  it  can
       set  parameters  in  a  module  started in another file, can affect the
       defaults for other files, etc.

       When an &include or &merge directive refers to  a  directory,  it  will
       read in all the *.conf or *.inc files (respectively) that are contained
       inside that directory (without any recursive scanning), with the  files
       sorted  into alpha order.  So, if you have a directory named "rsyncd.d"
       with the files "foo.conf", "bar.conf", and "baz.conf" inside  it,  this
       directive:

           &include /path/rsyncd.d

       would be the same as this set of directives:

           &include /path/rsyncd.d/bar.conf
           &include /path/rsyncd.d/baz.conf
           &include /path/rsyncd.d/foo.conf

       except  that  it adjusts as files are added and removed from the direc‐
       tory.

       The advantage of the &include directive is that you can define  one  or
       more modules in a separate file without worrying about unintended side-
       effects between the self-contained module files.

       The advantage of the &merge directive is that you can load config snip‐
       pets that can be included into multiple module definitions, and you can
       also  set  global  values  that  will  affect  connections   (such   as
       motd file), or globals that will affect other include files.

       For example, this is a useful /etc/rsyncd.conf file:

           port = 873
           log file = /var/log/rsync.log
           pid file = /var/lock/rsync.lock

           &merge /etc/rsyncd.d
           &include /etc/rsyncd.d

       This  would merge any /etc/rsyncd.d/*.inc files (for global values that
       should stay in effect), and then include any /etc/rsyncd.d/*.conf files
       (defining modules without any global-value cross-talk).

AUTHENTICATION STRENGTH
       The  authentication protocol used in rsync is a 128 bit MD4 based chal‐
       lenge response system. This is fairly weak protection, though (with  at
       least one brute-force hash-finding algorithm publicly available), so if
       you want really top-quality security, then I  recommend  that  you  run
       rsync  over ssh.  (Yes, a future version of rsync will switch over to a
       stronger hashing method.)

       Also note that the rsync daemon protocol does not currently provide any
       encryption  of  the  data that is transferred over the connection. Only
       authentication is provided. Use  ssh  as  the  transport  if  you  want
       encryption.

       You  can also make use of SSL/TLS encryption if you put rsync behind an
       SSL proxy.

SSL/TLS Daemon Setup
       When setting up an rsync daemon for access via SSL/TLS, you  will  need
       to  configure  a proxy (such as haproxy or nginx) as the front-end that
       handles the encryption.

       o      You should limit the access to the backend-rsyncd port  to  only
              allow  the  proxy  to connect.  If it is on the same host as the
              proxy, then configuring it to only listen on localhost is a good
              idea.

       o      You  should  consider turning on the proxy protocol parameter if
              your proxy supports  sending  that  information.   The  examples
              below assume that this is enabled.

       An example haproxy setup is as follows:

           frontend fe_rsync-ssl
              bind :::874 ssl crt /etc/letsencrypt/example.com/combined.pem
              mode tcp
              use_backend be_rsync

           backend be_rsync
              mode tcp
              server local-rsync 127.0.0.1:873 check send-proxy

       An example nginx proxy setup is as follows:

           stream {
              server {
                  listen 874 ssl;
                  listen [::]:874 ssl;

                  ssl_certificate /etc/letsencrypt/example.com/fullchain.pem;
                  ssl_certificate_key /etc/letsencrypt/example.com/privkey.pem;

                  proxy_pass localhost:873;
                  proxy_protocol on; # Requires "proxy protocol = true"
                  proxy_timeout 1m;
                  proxy_connect_timeout 5s;
              }
           }

EXAMPLES
       A  simple  rsyncd.conf file that allow anonymous rsync to a ftp area at
       /home/ftp would be:

           [ftp]
                   path = /home/ftp
                   comment = ftp export area

       A more sophisticated example would be:

           uid = nobody
           gid = nobody
           use chroot = yes
           max connections = 4
           syslog facility = local5
           pid file = /var/run/rsyncd.pid

           [ftp]
                   path = /var/ftp/./pub
                   comment = whole ftp area (approx 6.1 GB)

           [sambaftp]
                   path = /var/ftp/./pub/samba
                   comment = Samba ftp area (approx 300 MB)

           [rsyncftp]
                   path = /var/ftp/./pub/rsync
                   comment = rsync ftp area (approx 6 MB)

           [sambawww]
                   path = /public_html/samba
                   comment = Samba WWW pages (approx 240 MB)

           [cvs]
                   path = /data/cvs
                   comment = CVS repository (requires authentication)
                   auth users = tridge, susan
                   secrets file = /etc/rsyncd.secrets

       The /etc/rsyncd.secrets file would look something like this:

           tridge:mypass
           susan:herpass
