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 |
[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.
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
~/.clush.conf
This is the per−user configuration file.
/etc/clustershell/clush.conf
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).
