I am running RHEL8. My computer has two new micro connector nic connections. When I type "ifconfig" or "ip address" the IP address does not print, only the MAC address prints. I used the NetworkManager to configure the ports with IP addresses, Netmask etc. Saved these settings and rebooted the computer. Checking the config scripts in /etc/ the setting that I just set are there. but still only the MAC address appears at "ifconfig" and I cannot ping myself from the command line. Getting error, network not available.

Anything to do with your other RHEL networking threads??

You don't post what the output of your "ip address" command actually is, so it's hard to guess...and you also don't say anything about your hardware, or whether or not you ever had networking functional on that system. But since you've been using Linux for thirteen years now, and are using Red Hat Enterprise 8, have you contacted Red Hat support?? RHEL is a commerical, pay-for distro. If you're using the registered developers version, you still have access to the Red Hat knowledgebase articles as well just by signing in.

What desktop GUI are you using? Because if you don't get an address at all, either you don't have functional hardware, or you haven't filled in the necessary information.

Precisely how? And how did you save the settings?
Do the ifcfg scripts include ONBOOT=yes? If not, the settings are not put into effect.

Can you show us the output of nmcli con? That's the list of all NetworkManager connections and their status.

It is a brand new computer from a vendor. There is a lot of information printed from an ifconfig command.
I used ethtool -o em1 to verify that the ethernet ports were seen by the os. It makes the led at the port flash. I use it to identify which is port 1 and which is port 2. This computer is stand alone so me getting files off of it onto my company network is not an easy task. Our network security is extreme. As soon as I get a file I will post the output on this thread. I set the networking information for both ports in the NetworkControl app included with the OS. Looking at the /etc/sysconfig/network-scripts/ files for each port the data appears in those files. Upon restart of the computer the information persists in those network-scripts files. but the problem persists.

ONBOOT is set to YES.

I used the NetworkControl utility in the OS to make and save the changes.
It is a stand alone computer. Its time consuming to get files off of it to our company network. I will do that and get the information you requested and post it here. Might not be until tomorrow.

Both of those posts are from me one regarding a library that RedHat decided to leave out of version 8. My understanding is that its only function is to support legacy NIS functionality and shouldn't be contributing to the problem that I am seeing.

Here is my config file: What I'm seeing suggests I am stuck in ipv6 when I should be in ipv4. How should I change this configuration to get to where I need to be.

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=no
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=eno1
UUID=19e3b53d-b2d8-4378-8606-02326159ae95
DEVICE=eno1
ONBOOT=yes
IPADDR=192.168.200.72
GATEWAY=192.168.200.104
NETMASK=255.255.0.0
IPV6_PRIVACY=no
HWADDR=3C:EC:EF:1B:9A:54
PREFIX=16
PEERDNS=no
PEERROUTES=no

So essentially a duplicate of your other thread:
https://www.linuxquestions.org/quest...l8-4175686480/

Again: you've been using Linux for thirteen years now, and are using RHEL 8. Have you contacted Red Hat support?? And you still don't answer what desktop GUI you're using, or how you're configuring things. Why can you not set your interface to use DHCP, get a working address, then modify the address accordingly?
