Ubuntu images, i'm not sure if CentOS was affected, but on checking the CentOS image I am using here it appears fine (i.e. it's using 1000Hz).

SSH into your new instance.

Fetch the EPEL repository definitions from the Fedora Project - the RightScale image I am using included some EPEL settings so I disabled them (by editing the .repo files, an exercise for the reader!) in favour of using the direct EPEL release rpm -ivh http://www.mirrorservice.org/sites/dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm …

* At least, yum on CentOS 6.4 and older installs an unsupported version of Ruby , which is 1.8.7 (as of summer 2013). YMMV if that's your ruby is that old.

Deploying to S3 with s3cmd

Setting up the bucket

Create your bucket with the AWS console . s3cmd can do it too, but use the AWS console for hosted sites, because there's other settings you can only do in the console anyway.

Linux kernel version 2.6.37 to 3.8.9 are affected by this exploit. I will explain this exploit from the kernel side and the userland side to help readers get a better understanding of how exactly it works.

Hopefully, my long (and insane) story …
