Programs that pitch themselves as CA’s like EJB CA and Dogtag attempt to answer some of those questions by automating the issuing of certificates, using REST interfaces for easy access and LDAP for limiting who can do what.

It’s a good exercise to get the juices flowing: how would you automate this? What are the variables? How does the information flow? How do you do it at scale? What do you keep? What do you throw away? Where are the pain points? Now, of course you could do it all yourself, like Jamie Nguyen does over at Jamie on Linux, and I recommend that you do that at least once. I don’t want to have to worry about open ssl versions, remember a gazillion flags, drop down the command line, remember important bits of information, etc

Once FreeNAS has loaded, it's possible to select from various entries on the main menu, or detach the PC from a monitor and log in to the web interface from another PC on the same network. Select the spare USB drive (FreeNAS will not install on the one containing the OS so fear not if you select the wrong one) with the spacebar.

If nothing appears, you may need to hit the boot menu shortcut for your motherboard (ours is F11) during startup or make sure the USB drive has been successfully set up. When firing up your FreeNAS PC, you should see a boot screen that displays FreeNAS as an option.
