NAMEclush.conf - Configuration file for clush
DESCRIPTIONclush(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 [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 /usr/bin/ssh). ssh_options Set additional options to pass to the underlying ssh command.
EXAMPLESSimple 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~/.clush.conf This is the per-user configuration file. /etc/clustershell/clush.conf System-wide configuration file.
HISTORYAs 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).
