Hey folks, I stumbled upon this while looking for something else http://www.linux.com/archive/feature/151340 And it is something I could actually really make use of. But right on that site they list 3 different ones, and so I'm wondering what all is out there and what I should use. Is there one that is part of the standard CentOS? thanks, -Alan -- ?Don't eat anything you've ever seen advertised on TV? - Michael Pollan, author of "In Defense of Food"

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. -- Les Mikesell lesmikesell at gmail.com

It's available in .tgz with spec-file and rebuilds nicely on c5 with rpmbuild -tb ... https://computing.llnl.gov/linux/pdsh.html A few examples of what pdsh can do: - pick hosts with compact expressions: -w n[3-10,44] - settable fanout (run on X hosts in parallel) - remote command timeout - pdcp command that allows the copying of file - nifty post-processor that compats output: $ pdsh -w n[1-3],n5 uname -r | dshbak -c ---------------- n[1-3,5] ---------------- 2.6.18-164.11.1.el5 /Peter> Is there one that is part of the standard CentOS? > > thanks, > -Alan-------------- next part -------------- A non-text attachment was scrubbed...

I believe it is available in rpmforge, so there is no need to rebuild it if you don't want. I highly recommend it. In addition to the examples already cited, you can build a text file of commonly used groups of nodes and just use that to point PDSH at. If you really, really want to get fancy you can... but for more advanced uses just peek at the docs. -geoff --------------------------------- Geoff Galitz Blankenheim NRW, Germany http://www.galitz.org/ http://german-way.com/blog/
