Ubuntu Manpage: clush.conf - Configuration file for clush

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 of ssh connectors.

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).
