       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

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

              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


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