Hello

I ran: command: nmtui

I set the IP4 and IP6 to automatic

I set the primary DNS with the IP my cable company gave

When I try to "activate" the connections they fail,

When I run this command,

systemctl restart network

I get an error

"job for network.service failed because the control process exited with the error code. See "systemctl status network.service" and "journalctl -xe" for details

I just had static IPS installed yesterday from my cable provider and trying to set up the server,

Can anyone give me advice or help me?

whats in these files? im assuming centos 7

/etc/resolv.conf

/etc/sysconfig/network

/etc/sysconfig/network-scripts/<interface-name>

I and getting permission denied, when enter those

You need to sudo or use su to access those files as root.

Should be user readable files.

if you still get permission denied, su - to root and run same commands. On third command change <interface-name> to your interface-name.

Also post:

If you can't read /etc/resolv.conf as a user, you can't look up hostnames either.

The normal network startup for systemd based systems is NetworkManager, not network, which is a legacy network startup. These two are not mixable.

what are you trying to achieve?
connect a desktop computer to the internet?
why do you think you need to set the DNS manually? it should just work.
then you should do what it says to get more details.

in any case, i'm pretty sure there's no systemd service called "network.service". it might be "networkd.service".

ahh, i see. you want to run a server.
what else have you done to set up a server?
what system?

Not "service" but there is a network.target that can cause the invocation of other service units.

BTW, one added question to your list is:

What distribution are you using?
