Lab 3.2 How to verify the network connections function
Hello,
I have been working on the exercise 3.2 where I should create the appropriate network configuration files. Although I already did what the solution of this exercise says, I'm not sure how I can verify it the network connections functions.
When I checked the status of the networking services, the ouput is the following:
ronny@lfs-networking:/etc/network$ sudo systemctl status networking │ ● networking.service - Raise network interfaces │ Loaded: loaded (/lib/systemd/system/networking.service; enabled; vendor pre│ Active: active (exited) since Mon 2020-09-14 16:34:06 CST; 3h 51min ago │ Docs: man:interfaces(5) │ Main PID: 318 (code=exited, status=0/SUCCESS) │ Tasks: 0 (limit: 1150) │ Memory: 0B │ CGroup: /system.slice/networking.service
Is this the correct way to check the network connections function?

Hi ronnyhedz,
Line 4 "active" is usually "active(running)" indicating the network service is up. The output shows the "network" service has exited and is non functional.Lets see what you have, please run these commands and post the output:
lsb_release -a
/home/student/LFT/ready-for.sh -V
sudo systemctl | grep -i network
**My test system: **
**[student@centos ~]$ lsb_release -a **

Hello,
This is what I got:
No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 10 (buster) Release: 10 Codename: buster
ronny@lfs-networking:~$ /home/student/LFT/ready-for.sh -V -bash: /home/student/LFT/ready-for.sh: No such file or directory
ronny@lfs-networking:~$ sudo systemctl | grep -i network [sudo] password for ronny: networking.service loaded active exited Raise network interfaces systemd-timesyncd.service loaded active running Network Time Synchronization network.target loaded active active Network
I'm using a debian machine with virtualBox. I'm a ubuntu user but I don't want to mess up my computer while I'm practicing, that's why I created a virtual machine. I'm using debian as a "server" on which I connect through my terminal.

Hi ronnyhedz,
I think I see some of the challenges. We fully understand you do not want to mess with the base system on your machine and VM's are a great way to experiment with very low impact to an installed system.
We provide pre-created Virtual Machine Images that we use to test the class environment and are highly recommended to be used. You may use the same or different distro as you see fit, pick one you are comfortable with. The most common disto's are Ubuntu and CentOS.
Information on the VM is available at: "https://training.linuxfoundation.org/cm/prep/"
There is also a script at "https://training.linuxfoundation.org/cm/prep/" , "ready-for.sh", that helps prepare your system for class please run it in the VM to acquire most of the components to run the class. The instructions are on the web page.
This page also has a section on using VM's and some assistance documents for installing your own VM or machine.Regards Lee
