Chroot in OpenSSH
bsdphx writes "OpenSSH developers Damien Miller and Markus Friedl have recently added a nifty feature to make life easier for admins. Now you can easily lock an SSH session into a chroot directory, restrict them to a built-in sftp server and apply these settings per user. And it's dead simple to do. If you need to allow semi-trusted people on your computers, then you want this bad!"
Understanding the issues is better than parroting what you've heard from random sources. Given the OpenBSD and OpenSSH track record for security it's obvious they have some serious clues about security.
