FreeBSD Jail Management jailctl Copyright (c) 2004, 2005 Eirik Øverby (Document last updated on April 6, 2005) INTRODUCTION jailctl was originally written to overcome some of the apparent shortcomings of FreeBSD 4.x-series; the complete lack of utilities to create and manage jails. This situation has changed somewhat with FreeBSD 5.x, but instead of giving up on jailctl I have decided to upgrade it to support this new platform as well - and to reap the benefits of the new tools available in 5.x. Although there are a few other packages out there that help doing this, I wasn't really happy with any of them and - thinking I could do better - decided to write a jail management script myself. Whether or not I have succeeded in creating something useful for anyone other than myself is yet to be determined. FEATURES jailctl is a /bin/sh script, which currently has the ability to: - Start and stop jails - Create jails (with installworld and subsequent cleaning up) - Upgrade jails (with installworld and mergemaster) - Deleting jails - Backing up jails - Restoring jails - Show jail status and process list per jail DOWNLOAD jailctl can be downloaded here. INSTALLATION Consult the INSTALL file for installation instructions. If you don't use the port (sysutils/jailctl) to install, make sure you consult the jailctl(1) man page, after copying the jailctl.1.gz file to /usr/local/man/man1 if necessary (as described in INSTALL). FUTURE PLANS - More per-jail configuration - Support for file-based and remote filesystems for jails - Support for mounting host /usr, /bin, etc. in jails - Tool/option to generate jail configuration defaults from a series of questions, adduser style - Web-interface for jail control - Host-based firewalling on a per-jail basis - ... and more ...
