Nope, this is incorrect behaviour. INADDR_ANY in jail means: 10.1.1.2 or 10.1.1.3, but not 10.1.1.4. +> 2. Neat. :) I'm going to add sysctls when I get a chance for the mount +> hiding.

Everything that you can check IMHO is to check every parent directory of opened file if it isn't equal to jail chroot directory. But this is slow and stupid, because there could be many jails with shared chroot directory. +> 3.

Nope, but jail runned in jail can't use IPs that aren't binded to parent jail and securelevels are checked recursively. -- Pawel Jakub Dawidek UNIX Systems Administrator http://garage.freebsd.pl Am I Evil?
