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 | jail_enable="YES" | jail_list="cachingdns" | | # Caching-nameserver jail | jail_cachingdns_hostname="ns1.example.com" | jail_cachingdns_ip="192.0.2.15" | jail_cachingdns_interface="bge0" | jail_cachingdns_rootdir="/var/jails/caching-dns" | jail_cachingdns_exec="/usr/local/sbin/named" | jail_cachingdns_devfs_enable="YES" | jail_cachingdns_devfs_ruleset="devfsrules_thin_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. -- Chris Cowart Lead Systems Administrator Network & Infrastructure Services, RSSP-IT UC Berkeley
