Lab 04: DHCP - squatchulator/Tech-Journal GitHub Wiki

Intended to show how to install and configure Linux DHCP services on dhcp.yourname.local.

Installing/Configuring DHCP Services

  • Using PuTTY or Powershell, ssh to DHCP01
    • PuTTY can't be downloaded on AD01, so if done from there do through Powershell.
  • You can adjust the lease with 'default-lease-time xxxx (seconds)' and 'max-lease-time xxxx (seconds)' in the conf file.
  • Type ':w' and ':q' to save and quit vi
  • To start DHCP type 'sudo systemctl start dhcpd'. Check the status with 'systemctl status dhcpd'.
  • Enable DHCPD to start on boot with 'systemctl enable dhcpd'

Windows 10 DHCP Client

  • Change IPv4 properties to enable dynamic addressing

Related to DHCP

  • KRB5
    • Short for Kerberos. Kerberos is a network authentication protocol that encrypts the client's identity and proceeding communications once authenticated. It sits on top of UDP and TCP.
  • ICMP
    • Stands for Internet Control Message Protocol. This is used primarily to send and receive messages across networking devices such as error messages or operational information.
  • NBNS
    • Stands for NetBIOS Name Service. It translates human-readable names to IP addresses like DNS, but can run on top of other layer 3 protocols.
