Sometimes it may become profitable or necessary to jail the ssh daemon within a chroot. Unluckily there aren't many papers out there that explain the process of creating an appropriate jail and resolving all the necessary dependencies and errors.
This paper will show you how to successfully jail sshd itself. Opposed to many other papers out there it does not try to jail the users after logging in but rather put the entire daemon into the jail. This approach is interesting for anybody paranoid enough to want to protect against remotely exploitable flaws in the used sshd.
