pssh: Run Command On Multiple SSH Servers

I’ve already written about tentakel tool and shell script hack to run a single command on multiple Linux / UNIX / BSD server. This is useful to save time and run UNIX commands on multiple machines. Linux.com has published an article about a new and better tool called pssh:

If you want to increase your productivity with SSH, you can try a tool that lets you run commands on more than one remote machine at the same time. Parallel ssh, Cluster SSH, and ClusterIt let you specify commands in a single terminal window and send them to a collection of remote machines where they can be executed.

    Take a look at Dancer’s shell, too.

    Hi guys,
    I’ve tried running these versions of pssh on RHEL 5.2:

    The older versions install but say Traceback (most recent call last):
    File "/usr/bin/pssh", line 21, in ?
    from basethread import BaseThread
    ImportError: No module named basethread

    The latest version doesn’t install error: Failed dependencies:
    python(abi) = 2.5 is needed by pssh-1.4.3-1.noarch

    Any ideas?

    instead of this “Parallel Distributed shell” (pdsh) is the good option.
    PSSH is a bit typical to configure.
