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
Should clush display additional (node count) information in
buffer header? (yes/no)
Set the verbosity level: 0 (quiet), 1 (default), 2 (verbose) or
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.
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)
