Well, I should correct myself here, in that these examples are not jails, but merely chroot'd environments. A jail is very similar (in fact, it sets up a chroot internally) but also limits the machine's hostname/IP address, and prevents access to shared resources. I think there's a man page (maybe even two) for it. --K To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
