Identifying system hardware using lshw

You can use the ip command, or directly list the hardware in your system to find the logical name of

your network interface card. However, lshw is also an interesting command to know in case you are

working in an unfamiliar system environment.

sudo lshw

lshw $$help

Use lshw command to export your hardware configuration to a file called $$hardware$.$html$$ in HTML

format $($use the redirection special character $>$ to accomplish this$).$

Transfer this file out of your VM and into your host computer using SFTP and examine the file using a

web browser.

Now try to specify the $$class$$ of hardware in your VM as a network for the lshw command and examine

the output:

sudo lshw $-$class network

Run the command again and redirect the output of this command to a file called $$network$.$txt$($Do NOT

use HTML format this time$).$

Specifying DNS to your DHCP$-$enabled NIC

As you may be aware DHCP can provide many settings to the client. The minimum requirement for a

client to be able to connect to a network is IP$,$ Subnet Mask, and a Gateway $($if connecting to an outside

network or Internet$).$ However, DHCP can also deliver DNS$,$ Domain and many other configurations as

needed. In this exercise, you will specify DNS for your first NIC that is set to DHCP using Netplan.

Edit your netplan $.$yaml file to specify DNS nameserver IP addresses $1\mathrm{.}1\mathrm{.}1\mathrm{.}1$ and $1\mathrm{.}0\mathrm{.}0\mathrm{.}1.$ When done try

the settings and apply. Now ping google.ca to see if your DNS is working $($i$.$e$.$ your system can figure out

what the IP address for the domain google.ca is and can successfully ping the IP address$).$ You can hit

Ctrl$+$C to cancel or stop the command from running $($to stop the ping$).$ You may want to try to ping

$1\mathrm{.}1\mathrm{.}1\mathrm{.}1$ itself if for some reason your DNS service is not resolving names.

You can also verify that netplan applied your settings properly by running:

resolvectl status

It should give you an output similar to this:

Make a copy of your netplan YAML file to your home folder and rename it to $$netplanConfig$.$yaml.txt$$

and download it to your local machine via SFTP$.$
