Lab Configuration 4 - adaley0518/Tech_Journal GitHub Wiki

Steps for Lab Configuration

  1. might have to install DHCP servers. yum install dhcp?

  2. steps to disable IE Enhanced Security Configuration

3.Install PuTTY * run 'putty-64bit-0.72-installer.msi * shortcut to the .exe of putty to open

  1. Connect via PuTTY

    • under Host Name(or IP Address): dhcp01-amber
    • Port: 22
    • connection type: SSH
    • saved Sessions: dhcp01-amber
    • save then click on dhcp01-amber and open
    • login as: amber & enter password
    • 'hostname' --> dhcp01-amber
    • 'whoami' --> amber
    • 'sudo yum install dhcp' ( if i see table with dependencies resolved, worked)

  2. Configuring DHCP Services

  3. Starting DHCP Servies

    • 'systemct1 start dhcpd'
    • 'systemct1 status dhcpd' (should be active and running in green)

  4. Enabling the Service to Start at Boot

    • 'systemct1 enable dhcpd' ( should say: created symlink from etc)

  5. Configuring the Firewall to Allow Incoming DHCP Requests

    • 'firewall-cmd --list-all' (should be public active either way continue so it saves when rebooted)
    • 'firewall-cmd --add-service=dhcp --permanent'
    • 'firewall-cmd --reload'
    • 'firewall-cmd --list-all' (should show services: ssh dhcpv6-client dhcp)
    • type exit till out of PuTTY

  6. Windows 10 DHCP Client

    • on wks01 change the IPv4 networking to 'Obtain an IP address automatically' & 'Obtain DNS server address automatically', press okay

  7. CHECK in wks01

    • First:
      • cmd
      • ipconfig /all
      • should see DHCP Server as 10.0.5.3
      • IP should be in range set earlier '10.0.5.101'
      • domain name: amber.local
      • netmask: 255.255.255.0
      • gateway: 10.0.5.2
      • DNS: 10.0.5.5
    • go back to dhcp01 for PuTTY
      • 'sudo cat /var/log/messages | grep wks01-amber (wks01-amber may vary if it doesn't work)
        • should be about 5 dhcp01-amber logs
    • (use wireshark)go to wks01 (as admin/ amber.daley-adm) powershell
      • 'ipconfig /release'
      • 'ipconfig /renew' (might freeze so use ctrl c)
      • 'ipconfig /all' (should see the same info as in the cmd)
      • after check wireshark to see a packet for 'release' 'discover' 'offer' 'request' and 'ACK'
