This document will describe the setup of jail(8) and how-to configure all applications to work properly within a jail(8). It has the following design criteria/assumptions:

• /usr/ports is shared throughout all installations (so are all the configuration for the ports then) and every system build all ports himself.
• my sample jail is called pzwet and is located in file:/usr/jail/pzwet

Important: Your jail server should not run any public facing services which does 'wildcard' binding to IP addresses, else it will 'claim' the service before your jail can take it. Tip: Jails does NOT have a local loopback device, so you will need to use UNIX sockets on places you would normally use the loopback address.

First make sure to install the jail using the ​method in the handbook

pzwet# make -C /usr/ports/security/sudo WITH_INSULTS=yes BATCH=yes install clean pzwet# make -C /usr/ports/devel/subversion WITH_MOD_DAV_SVN=yes APACHE_VERSION=22 BATCH=yes install clean pzwet# make -C /usr/ports/ports-mgmt/portaudit BATCH=yes install clean; /usr/local/sbin/portaudit -Fda

Update port INDEX tree and report on pending upgrades every Saturday: pzwet# echo '0 3 * * sat root /usr/sbin/portsnap -I cron update && /usr/sbin/pkg_version -vIL=' >> /etc/crontab
