Recently, I had to do a deployment on a bunch of servers with no Puppet Agent installed. Unfortunately, adding a decent Puppet Infrastructure to the setup was out of discussion, so I started using mssh and had a little cry. You can imagine, that it didn’t took long to reach the point where mssh wasn’t flexible enough. And let’s face it – once you get used to Puppet everything else doesn’t feel right anymore. The solution to my plight was simple: just use Puppet without a Puppet Master.
Since a fair amount of time, it’s possible to integrate your Juniper Switches and Routers with your Puppet infrastructure. This is done by installing a JunOS-specific Puppet Client directly on the Switch itself (let’s just talk about Switches, but the same applies for Routers) and a few minor modifications on the Puppet Master – of course, your Master will still be able to serve non-JunOS Agents as usual.
Ever wondered what’s that

A few month ago, Google dropped support for RHEL and it’s derivats like CentOS or Scientific Linux of the Chrome Browser. If you want or need to use Google Chrome, you are pretty much screwed. The good news is that the CentOS loving fellow Richard Lloyd hacked a script to backport Chrome with some Fedora libraries to run on Windows NT 3.51 – just kidding – CentOS 6.x just fine.
