In (HPC) clustering pdsh is very popular. It's available in .tgz with
spec-file and rebuilds nicely on c5 with rpmbuild -tb ...
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
