chroot envo builder

. $ ./chroot.sh /bin/{ls,cat,nano,echo,rm,bash} /usr/bin/vi /etc/hosts

. $ sudo groupadd chrootjail . $ sudo adduser user chrootjail

• All what remains is to configure sshd to automaticaly redirect all users from the chrootjail usergroup to the chroot jail at /var/chroot. This can be easily done be editing the sshd configuration file /etc/ssh/sshd_config. Add the following to /etc/ssh/sshd_config:

Match group chrootjail ChrootDirectory /var/chroot/

• and restarting ssh:

$ sudo service ssh restart

$ ssh user@localhost
