Re: [CentOS] best parallel / cluster SSH

It depends on what you need to do.  If you really have enough machines or long-running jobs that a shell loop through them isn't practical, you might want something higher-level like cfengine or puppet, or at least something running under cron to make them independent.

cfengine or puppet (or something else - slackmaster?) are where I want to be eventually - but in the immediate term something like this would help a lot. e.g bouncing my 4 front-end apache servers on 4 different boxes. That sort of thing.

I was actually going to start another "configuration management redux" thread as a follow up to a thread I started a few months ago.
