Lab 02 DNS + ADDS Role

Linux Configuration

Working Notes

The purpose of this lab was to configure an operating system called Centos. The task was to configure the OS to make it useful and manageable. First the Network adapter had to be changed for the VM to SYS255-03-LAN-jude.lindale. From there the actual network settings needed to be configured by using nmtui and manually inputting the IPv4 address information. The IP Address and Netmask being 10.0.5.3/24, the Gateway 10.0.5.2, the DNS 10.0.5.5, and the search domain jude.local which the DNS is attached to. And to change the hostname to dhcp01-jude. Next was to add a user profile on the linux machine to the wheel group. As root I ran useradd jude which created a profile, then passwd [password] which put a password for the user, and then usermod -aG wheel jude which added the user to the wheel group. After making sure the networking was good, the next task was to go on to the wks01 VM and add dhcp01 to add a A and PTR records for dhcp01 which refers to lab 02. Once added I could ping dhcp01 from PowerShell but could not connect via ssh. This was because the in and out ICMP firewall rules would not allow the connection and therefore had to be changed to allow the connection. Once that had been done I was able to make the connection to then run the commands for the lab.
