The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

• a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
• H: preserves hard-links
• A: preserves ACLs

How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

About me

I’m an intermediate/advanced chef user. My main usage has been as a client of the services that chef provides, and not operating the server. My comfort zone is that I am very happy to write and hack on fairly complicated chef cookbooks, LWRPs, and chef-solo work, but I don’t work much with the chef server - I’ve opted to use the hosted service in the past, and very much enjoyed the service.

Why Saltstack?

I’m interested in saltstack. When I first started working with chef in 2011, saltstack was very new, so I learned chef, as the more mature option (though it was still fairly new). Now salt is in a fairly mature phase where it seems to be able to handle the same classes of installation and configuration management that I’ve seen chef work with in the past. This impression is backed up by users of Salt who are clearly using it in their day-to-day operations. So I’m trying it out.

References, etc.
