# Chroot Jail for SSH Access 
# Tested on Ubuntu 14.04.2 LTS and Debian GNU/Linux 8 (jessie)

# Reference : http://allanfeid.com/content/creating-chroot-jail-ssh-access

# Had to add/change several things to make it work, including:
# - create lib64 folder
# - copy whoami dependencies that ldd doesn't show to fix 'I have no name!'
#   in the customized prompt + create passwd file

Picking the right architecture = Picking the right battles + Managing trade-offs

##Basic Steps

1. Clarify and agree on the scope of the system

  • Who is going to use it?
  • How are they going to use it?
