description
In this lab we set up the DHCP server in Linux, but we haven't added any DHCP functionality yet, just networking configurations and adding a user

Lab03 - Linux Setup

mntui

• network manager TUI
• used to set up network configuration & can change hostname
• (remember to set search domain to charlotte.local)
• systemctl restart network or systemctl restart NetworkManager to restart network after config change

set hostname

hostnamectl set-hostname dhcp01-charlotte

creating privileged user

• useradd charlotte
• passwd charlotte
• usermod -aG (wheel/sudo) charlotte - RH=wheel, Debain=sudo

ipconfig DNS commands

• /flushdns: clears DNS cache and forces the computer to regain all DNS entries from the DNS server
• /registerdns: re-registers all domain names and IP addresses
