Lab 3: DHCP Configuration

I began the lab by booting up my dhcp01 vm and logging in to the root account. I navigated to the system config file in /etc/sysconfig/network-scripts and edited it by adding/modifying these lines: (Name: dhcp01-sam, IPADDR: 10.0.5.3, DNS1: 10.0.5.5, GATEWAY: 10.0.5.2, DOMAIN: samjohnson.local). I restarted the network interface (/etc/init.d/network restart) and began to add a privileged user using the following commands (adduser, passwd, usermod -aG wheel). I used the ping command to test connectivity to my network, and once that was established, I moved on in the lab.
Next, I switched to my ad01 VM, and configured my DNS server to add a forward and backward lookup pointer for the DHCP VM. I tested this by using the WKST VM (Powershell) to ping the DHCP server using the username dhcp01-sam.
Following confirmation that DHCP had been seamlessly added into my network, I pursued a SSH connection to my DHCP server from AD01. To do this, I navigated to 'Manage optional features' and installed OpenSSH server. In the Powershell CLI, I used the command 'ssh samjohnson-adm@dhcp01-sam' to remote login into my Dhcp server. I used command such as (pwd, cd, cd.., ls -l, ls -la, man, mkdir, sudo -i, and history) through ssh to navigate around my dhcp server from my AD01 VM.
