vagrant-network101

Status: COMPLETE: DHCP

A project to try out basic Network concepts: DHCP, DNS, PXE, iPXE, HTTP Boot

Exercise 1 - DHCP

Bring up 4 VMs:

• One Server - DHCP - will provide DHCP services on private network 192.168.1.0/28
  • Subnet /28 has 16 hosts(14 usable):
    • NETWORK ID: 192.168.1.0
    • BROADCAST: 192.168.1.15
    • NETWORK RANGE: 192.168.1.1 - 192.168.1.14
    • DHCP IP: 192.168.1.1
    • NETMASK: 255.255.255.240
• Three Servers - DHCP Clients. The private network on NIC2 will be configured by the DHCP. This means IP address assigned on NIC2 will be within the define DHCP range defined above.

Base Usage

$ git clone https://github.com/dlux/vagrant-network101.git
$ cd vagrant-network101
$ vagrant up

# VERIFY DHCP SERVER SETUP:
$ vagrant ssh dhcpserver
$ sudo systemctl status isc-dhcp-server
$ exit

# VERIFY DHCP IP ADDRESS ON CLIENT:
$ vagrant ssh dhcpclient-1
$ ip a

Exercise 2 - Adding DNS

Using base configuration from Exercise1. A new VM is added to serve as the DNS - set to non autostart hence VM must be turn on manually. Additionally consider using same DHCP machine to host DNS by running intall_dns script

E2 - Usage

# TO ADD A DNS SERVER
$ vagrant up
$ vagrant up dnsserver
# ALSO MIGHT PREFER RUNNING install_dns.sh ON SAME DHCP SERVER VM

Exercise 3 - Adding NAT server

Using base configuration from Exercise1. A new VM is added to serve as the NAT - set to non autostart hence VM must be turn on manually. Client1 will be use to test the new NAT server routing traffic via private network

E3 - Usage

# TO ADD A DNS SERVER
$ vagrant up
$ vagrant up natserver

Exercise 4 - Adding PXE server

Using base configuration from Exercise1. A new VM is added to serve as the PXE server. It is set to non autostart hence VM must be turn on manually. PXE server uses fogproject.

Client1 will be use to test PXE server routing traffic via private network.

Status: Incomplete TODO: configure dhcp, create base cirros image.

E4 - Usage

# TO ADD A PXE SERVER
$ vagrant up
$ vagrant up natserver
