jailkit - tools to make chroot jails easily

Jailkit is a set of utilities to limit user accounts to specific files using chroot() and or specific commands. Setting up a chroot shell, a shell limited to some specific command or a daemon inside a chroot jail is a lot easier and can be automated using these utilities.
Jailkit is a specialized tool that is developed with a focus on security. It will abort in a secure way if the configuration, the system setup or the environment is not 100% secure, and it will send useful log messages that explain what is wrong to syslog.
Jailkit is known to be used in network security appliances from several leading IT security firms, Internet servers from several large enterprise organizations, Internet servers from Internet service providers, as well as many smaller companies and private users that need to secure login in services or in daemon processes.
Currently, Jailkit provide jails for cvs, git, scp sftp, ssh, rsync, procmail, openvpn, vnc, etc.
Jailkit make available the following commands: jk_check, jk_chrootlaunch, jk_chrootsh, jk_cp, jk_init, jk_jailuser, jk_list, jk_lsh, jk_socketd, jk_uchroot, jk_update.
