Vagrantfile

#
# Vagrant environment with 3 machines:
#  * dhcpd4 - ISC dhcp ipv4 server
#  * dhcpd6 - ISC dhcp ipv6 server
#  * dhcpdoctor - runs dhcpdoctor against eny of the servers
#
# All three are connected to a caommon private network
# IP provisioning is done mostly via shell provisioner, because
# built-in vagrant options are too limited.
# dhcpdoctor has an extra IPv4 and IPv6 subnet so it can sumulate
# running as DHCP relay and still receive replies.
#
# Included centos boxes don't have virtualbox tools installed, so the
# working directory can't be mounted and is instead rsync-ed to VMs.
# To keep the code up to date while developing you sould run rsync-auto
# in a separate shell:
#
#     vagrant rsync-auto
#
