       clush.conf - Configuration file for clush


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

          1. command-line options

          2. user configuration file (~/.clush.conf)

          3. 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

       Configuration parameters of the Main section are described below.

       fanout Size of the sliding window of ssh connectors.

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

              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.

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

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

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

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

              Set the ssh binary path to use for remote connection (default is /usr/bin/ssh).

              Set additional options to pass to the underlying ssh command.


       Simple configuration file.

       fanout: 128
       connect_timeout: 15
       command_timeout: 0
       history_size: 100
       color: auto
       fd_max: 10240
       node_count: yes



              This is the per-user configuration file.


              System-wide configuration file.


       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).
