Yes. Are you configuring the jail via /etc/rc.conf already? Are you
using the rc script /etc/rc.d/jail to start your jails?
My complete config from /etc/rc.conf is:
| # Enable jails
| # Caching-nameserver jail
You can replace cachingdns with cp or whatever else you want. You can
also create multiple jails with different names.
I don't know if you're following the typical FreeBSD jail documentation
which gives you a complete FreeBSD installation inside the jail. Given
that I only need to run named, I have not done that.
Are you trying to run a complete FreeBSD install that allows user logins
inside your jail? Or are you simply trying to jail a single process? My
example above jails the single process named, and does not have an OS
install inside the jail's root.

I am doing a complete OS inside the jail and am starting it through
I have modified the devfs.rules so that they are now passing random
and urandom as devices. But the installation software is still
reporting that /dev/random is not working properly. Do you know of a
way that I can test /dev/random to see if it is actually working?
