Objectives

Objectives are listed below in each of their sections.


For a lab setup, using something like VirtualBox works great.
In order to practice the objectives below, setup a virtual machine lab:

  • server1.example.com
    • Description: Typically the “client” VM to perform anything from a “client” perspective (ie NFS client) when two servers are involved. Also used when only a single system is required to practice on.
    • CPU/Memory: 1 CPU/1024 MB memory
    • IP: 192.168.1.150 (bridged adapter)
  • server2.example.com
    • Description: Typically the “server” VM to function as a source for “server1” to perform tests (ie NFS server) against when two servers are involved.
    • CPU/Memory: 1 CPU/1024 MB memory
    • IP: 192.168.1.151 (bridged adapter)
  • ipa.example.com
    • Description: FreeIPA LDAP server to install for client authentication practice. FreeIPA also integrates a Kerberos KDC server. (Key Distribution Center)
    • CPU/Memory: 1 CPU/1024 MB memory
    • IP: 192.168.1.152 (bridged adapter)


Install CentOS 7 on all VMs (Basic Server) and set to the multi-user target.
