1. Openstack layer2

    A few months ago I implemented an RDO based openstack kilo release private cloud at one of our customers for their development platform. Through time we tackled a couple of issues so the cloud could be fitted into their work flows.

    We stumbled onto some minor issues and some major ones. Let's begin with the minor ones ;)

  2. Pakiti setup

    Nowadays it becomes more and more relevant knowing which version of a package is installed and having an overview of the packages infected by some bugs or security holes. That way you could see which servers are possibly vulnerable for those on the dark side.

    That way I'm sure dropbox can't read the data stored into it. Because no I don't trust anybody on the cloud!

    In the first part I will configure 2 dropbox services using a CentOS 6 Desktop, in the second part I will encrypt those 2 dropbox services using encfs.

    The first account you can just install and configure the normal way provided by dropbox itself. Here I configured my …

    find -type d -print0 | xargs -0 chmod 755
    find -type f -print0 | xargs -0 chmod 644
