synctool is a cluster administration tool that keeps configuration files synchronized across all nodes in a cluster. Nodes may be part of a logical group or class, in which case they need a particular subset of configuration files. synctool can restart daemons when needed, if their relevant configuration files have been changed. synctool can also be used to do patch management or other system administrative tasks.

Release Notes: Many new things were added in this major release. synctool now features node range syntax, which can be used on the command-line as well as in the config file to easily select or define ranges of nodes. Templates are new; they allow you to generate config files on the fly from a stanza file and some variables. synctool can now easily manage multiple clusters using one admin node, and it's also better at handling multiple operating systems. The new purge feature is ideal for making perfect mirrors of directory trees.
Release Notes: This release fixed a number of small issues and notably two larger ones: the PATH environment variable is now searched for the configured commands. This helps on multi-platform setups. The --erased-saved option now is an action by itself. Using --erased-saved will no longer trigger other updates to occur inadvertently.
Release Notes: This release fixes a bug in dsh-pkg commandline parsing. A nagios check script has been contributed to the project.
Release Notes: This release fixes a number of bugs present in the previous release. The comma-separated list of nodes and groups on the command line was not being parsed correctly in certain cases. Whenever output was being printed to stderr, the node name would not be printed in front of the message. An alternative way of uniquely identifying a node within the cluster was added. dsh-ping now also supports fping and Solaris ping.
Release Notes: HTML documentation has been added to the project. You may now use "synctool -e" to erase the ".saved" files. You may use the new command "dsh-ping" to check whether your nodes are alive. You may use the new command "dsh-pkg" to do package management. A new terse output mode has been added. The options -1, --single, --diff, and --ref may now be given multiple times on the command-line. Post-scripts for directories are now being run in the target directory rather than in the parent directory. Many new configuration parameters have been added. And there is more.
