Using clusterssh to admin multiple service consoles
We have our service consoles set up to disallow root logins and use sudo (with password) for access. Every once in a while this causes us some pain. How do you update file /etc/filex or run some command across a cluster or a bunch hosts when root privileges are needed?
There are multiple ways to approach this type of issue, but one I have not seen much of in the VMware blogosphere is clusterssh. It allows you to interactively type commands on a number of hosts at the same time. If something sticks out you can enter commands on any of the individual boxes.
Some linux distributions include this in their repositories so it can be pretty easy to give it a try (something like apt-get install clusterssh to install). It supposedly works on OS X too.
