ClusterSSH - What is it all about?

ClusterSSH is a tool for making the same change on multiple servers at the same time. The 'cssh' command opens an administration console and an xterm to all specified hosts. Any text typed into the administration console is replicated to all windows. All windows may also be typed into directly.

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.

Recent Updates

I have now started the re-write for Series 4 which includes moving away from using GNU tools to a standard Perl module layout.

I have also registered the 'App::ClusterSSH' module name on CPAN.

If anyone wishes to help with the code re-write, please email me. If you have any suggestions for extra items (or spot any typos), or you would like access to make changes yourself, please email me.

Some of the bugs in the tracker require specific installs/setups which I do not have access to for fixing/testing purposes. If you are able to help with resolving the current bug list, please email me
