Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Hello and thank you for viewing my thread. I don't now what I'm doing.
I have installed CentOS 7.4.1708 onto my VPS, updated to the latest kernel and attempted to install WHM/cPanel. During the installation I received a colorful red message that said
cPanel does not support NetworkManager enabled
systems. The installation cannot proceed.
Please consult your system documentation to
remove NetworkManager, replacing it with the network.service
I then removed NetworkManager and attempted to
Code:
systemctl start network.service
I got a message saying "Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details."
After entering systemctl status network.service I got this output
I have googled here and there and found some solutions. Creating a ifcfg-enp0s3 file in /etc/sysconfig/network-scripts directory is one solution. Is this a viable idea? I am also wondering how I can still connect to my vps if I uninstalled the program that was managing my connections (NetworkManager).
If you do not know the solution to this problem but have a good resource for understanding CentOS networking better please feel free to post that too.
Thank you the cPanel documentation did it even though I do not know what it was I was doing. Editing the ifcfg-eth0 and ifcfg-eth0:0 THEN enabling AND starting (What's the difference?) network.services seemed to do fix the problem of:
But now I can no longer SSH to my server. Was I suppose to configure a network interface file before I stopped networkmanager and switched over to network.service? The cPanel directions did not state that. There is one thing I did notice my ifcfg-eth0 and ifcfg-eth0:0 files did not contain a NM_CONTROLLED value that was according to the cPanel instructions suppose to be set to no "NM_CONTROLLED=no". So I added this to both eth0, eth0:0, and ifcfg-lo.
So I turned off network manager, edited the configuration files according to that documentation then enabled and started network.service but that left me unable to ssh to my server (currently vnc). Any ideas? Would configure a network interface file do anything?
Have you checked to see if there is an SSH server listening on port 22 (or whatever you configured it on)? Are you trying to reach it by a particular IP address, and is it still the same?
Simply starting a .service unit won't create the symlinks to get the unit started at boot.
From the systemctl man page
Quote:
enable NAME...
Enable one or more unit files or unit file instances, as specified on the command
line. This will create a number of symlinks as encoded in the "[Install]" sections of
the unit files. After the symlinks have been created, the systemd configuration is
reloaded (in a way that is equivalent to daemon-reload) to ensure the changes are
taken into account immediately. Note that this does not have the effect of also
starting any of the units being enabled. If this is desired, either --now should be
used together with this command, or an additional start command must be invoked for
the unit. Also note that, in case of instance enablement, symlinks named the same as
instances are created in the install location, however they all point to the same
template unit file.
Have you checked to see if there is an SSH server listening on port 22 (or whatever you configured it on)? Are you trying to reach it by a particular IP address, and is it still the same?
Code:
ip address
I have checked the sshd file and nothing has changed there and it is "allowed" through SELlinux. I have been searching the internet to try to find a command to check if the ssh port is open in iptables but can not find out how to do this. I thought I had CSF installed but I guess not. When I type in IP address I get the output of the attached picture. I am still trying to ssh to the same IP address and from the same IP address.
Your config files (ifcfg-eth0 and ifcfg-eth0:0) don't match the network device node name present (ens3)!
So to fix this I would have to change the name of the configuration files (ifcfg-eth0 ifcfg-eth0:0) to match the device node name? If this is correct where do I find the device node name and when I find it do I simply change the name of ifcfg-eth0 file and ifcfg-eth0 file to the name of this device node or do more changes have to be made in the configuration file itself?
