NAME

       clush.conf - Configuration file for clush

DESCRIPTION

       clush(1) obtains configuration options from the following sources in the following order:

          1. command-line options

          2. user configuration file ($XDG_CONFIG_HOME/clustershell/clush.conf)

          3. local pip user installation ($HOME/.local/etc/clustershell/clush.conf)

          4. system-wide configuration file (/etc/clustershell/clush.conf)

       For each parameter, the first obtained value will be used.

       The configuration file has a format in the style of RFC 822 composed of one main section:

       Main   Program options definition

   [Main]
       Configuration parameters of the Main section are described below.

       fanout Size  of  the  sliding window (fanout) of active commands for clush. This fanout is
              used to avoid too many concurrent connections and  to  conserve  resources  on  the
              initiating  hosts. In tree mode, the same fanout value is used on the head node and
              on each gateway (the fanout value is propagated).  That is, if the fanout is 16  on
              the head node, each gateway will initate up to 16 connections to their target nodes
              at the same time.

       connect_timeout
              Timeout in seconds to allow a connection to establish. This parameter is passed  to
              ssh. If set to 0, no timeout occurs.

       command_timeout
              Timeout  in  seconds  to  allow a command to complete since the connection has been
              established. This parameter is  passed  to  ssh.   In  addition,  the  ClusterShell
              library  ensures  that  any  commands  complete  in  less  than ( connect_timeout +
              command_timeout ). If set to 0, no timeout occurs.

       color  Whether to use ANSI colors to surround node or nodeset  prefix/header  with  escape
              sequences  to  display  them  in  color on the terminal. Valid arguments are never,
              always or auto (which use color if standard  output/error  refer  to  a  terminal).
              Colors  are  set to [34m (blue foreground text) for stdout and [31m (red foreground
              text) for stderr, and cannot be modified.

       fd_max Maximum number of open file descriptors permitted per clush process (soft  resource
              limit  for  open  files).  This limit can never exceed the system (hard) limit. The
              fd_max (soft) and system (hard) limits should be high enough to run clush, although
              their values depend on your fanout value.

       history_size
              Set  the  maximum number of history entries saved in the GNU readline history list.
              Negative values imply unlimited history file size.

       node_count
              Should clush display additional (node count) information in buffer header? (yes/no)

       verbosity
              Set the verbosity level: 0 (quiet), 1 (default), 2 (verbose) or more (debug).

       ssh_user
              Set the ssh user to use for remote connection (default is to not specify).

       ssh_path
              Set the ssh binary path to use for remote connection (default is ssh).

       ssh_options
              Set additional options to pass to the underlying ssh command.

       scp_path
              Set the scp binary path to use for remote copy (default is scp).

       scp_options
              Set additional options to pass to the underlying scp  command.  If  not  specified,
              ssh_options are used instead.

       rsh_path
              Set  the  rsh  binary path to use for remote connection (default is rsh). You could
              easily use mrsh or krsh by simply changing this value.

       rcp_path
              Same a rsh_path for rcp command. (Default is rcp)

       rsh_options
              Set additional options to pass to the underlying rsh/rcp command.

EXAMPLES

       Simple configuration file.

   clush.conf
       [Main]
       fanout: 128
       connect_timeout: 15
       command_timeout: 0
       history_size: 100
       color: auto
       fd_max: 10240
       node_count: yes

FILES

       /etc/clustershell/clush.conf
              System-wide clush configuration file.

       $XDG_CONFIG_HOME/clustershell/clush.conf
              User  configuration  file  for  clush.  If   $XDG_CONFIG_HOME   is   not   defined,
              $HOME/.config/clustershell/clush.conf is used instead.

       $HOME/.local/etc/clustershell/clush.conf
              Local user configuration file for clush (default installation for pip --user)

       ~/.clush.conf
              Deprecated per-user clush configuration file.

HISTORY

       As  of  ClusterShell  version  1.3, the External section has been removed from clush.conf.
       External commands whose outputs were used by clush (-a, -g, -X) are  now  handled  by  the
       library itself and defined in groups.conf(5).

SEE ALSO

       clush(1), groups.conf(5).
