FreeBSD Jail

[img_assist|fid=55|thumb=1|alt=Daemon] I am experimenting with setting up a “jail” inside of FreeBSD (on my Ultra 60). jail is a utility available on FreeBSD that imprisions a process and *all* of its descendants. It can be used as a virtual machine that runs an entire instance of FreeBSD or it can be used to encapsulate a single executable.

I have been playing with it, and I must say it is very cool indeed. Here are some links that will greatly streamline the process of setting up *your* jail:

• Making your own jail rc script
• Jail threads at BSDForums
• jexec - allows you to connect to your jail once it has been started (vi your rc script, presumably)
