pssh

pssh provides a number of commands for executing against a group of computers, using SSH. It's most useful for operating on clusters of homogenously-configured hosts. The package contains: - Parallel ssh (parallel-ssh, upstream calls it pssh), executes commands on multiple hosts in parallel - Parallel scp (parallel-scp, upstream calls it pscp), copies files to multiple remote hosts in parallel - Parallel rsync (parallel-rsync, upstream calls it prsync), efficiently copies files to multiple hosts in parallel - Parallel nuke (parallel-nuke, upstream calls it pnuke), kills processes on multiple remote hosts in parallel - Parallel slurp (parallel-slurp, upstream calls it pslurp), copies files from multiple remote hosts to a central host in parallel These tools are good for controlling large collections of nodes, where faster alternatives such as gexec and pcp are not available.
