I'll spare you the gory details of how I cut myself off from the machine, managed to create a jail with no access etc. etc. But yes, that was it - in summary: jail -c -v Does not actually *show* the fib being set, but will show an error if the setfib call fails. jexec Runs a process in the jail, using the prevailing fib - not the jails fib, you can rectify this by using 'setfib X jexec jail tcsh' I don't know if that last point should be considered a 'bug' or not... Many thanks for your help! -Karl
