Cluster SSH 3.22 (Series 3 branch)
01-23-2008
Cluster SSH opens terminal windows with connections to specified hosts and an administration console. Any text typed into the administration console is replicated to all other connected and active windows. This tool is intended for, but not limited to, cluster administration where the same configuration or commands must be run on each node within the cluster. Performing these commands all at once via this tool ensures all nodes are kept in sync. License: GNU General Public License (GPL)Changes:|

clusters - cluster names database SYNOPSIS
/etc/clusters DESCRIPTION
The clusters file contains information regarding the known clusters in the local naming domain. For each cluster a single line should be present with the following information: clustername whitespace-delimited list of hosts Expansion is recursive if a name on the right hand side is tagged with the expansion marker: ``*''. Items are separated by any number of blanks and/or TAB characters. A `#' indicates the beginning of a comment. Characters up to the end of the line are not interpreted by routines which search the file. Cluster names may contain any printable character other than an upper case character, a field delimiter, NEWLINE, or comment character. The maximum length of a cluster name is 32 characters. This information is used by Sun Cluster system administration tools, like cconsole(1M) to specify a group of nodes to administer. The names used in this database must be host names, as used in the hosts database. The database is available from either NIS or NIS+ maps or a local file. Lookup order can be specified in the /etc/nsswitch.conf file. The default order is nis files. EXAMPLES
