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."
