Managing Multiple Linux Servers with ClusterSSH

“If you’re a Linux system administrator, chances are you’ve got
more than one machine that you’re responsible for on a daily basis.
You may even have a bank of machines that you maintain that are
similar — a farm of Web servers, for example. If you have a
need to type the same command into several machines at once, you
can login to each one with SSH and do it serially, or you can save
yourself a lot of time and effort and use a tool like
ClusterSSH.

“ClusterSSH is a Tk/Perl wrapper around standard Linux tools
like XTerm and SSH. As such, it’ll run on just about any
POSIX-compliant OS where the libraries exist — I’ve run it on
Linux, Solaris, and Mac OS X. It requires the Perl libraries Tk
(perl-tk on Debian or Ubuntu) and X11::Protocol
(libx11-protocol-perl on Debian or Ubuntu), in addition to xterm
and OpenSSH. Installation

“Installing ClusterSSH on a Debian or Ubuntu system is trivial
— a simple sudo apt-get install clusterssh will install it
and its dependencies. It is also packaged for use with Fedora, and
it is installable via the ports system on FreeBSD. There’s also a
MacPorts version for use with Mac OS X, if you use an Apple
machine. Of course, it can also be compiled from source.”
