Weird network connectivity problem with my server

Rocky Linux General
1

I was able to setup my home server under RL8.
Thanks to @iwalker and others for their valuable input.
Also this page was very helpful: https://www.server-world.info/en/note?os=Rocky_Linux_8&p=firewalld&f=2

Now to the problem.
When booting the server I don’t have internet access. Only when I log in from the console as root do I get network connectivity. Nothing else need to happen than logging in.
This happens all the time. I booted the server 5 times waiting up to 10 mins after booting and no internet connectivity until I logged in.

Any idea what could cause the problem? I can’t find anything in google.

Thanks,

Wolfgang

You can try these three, first as standard user, then as root:

nmcli device status
nmcli connection show
ifconfig
3

And I just found out that when logging out from root the network connectivity goes away.

Output as normal user

enp3s0 is the pppoe.parent for ppp

That is very clear output, but you were supposed to run ‘ifconfig’, not ‘ip a’.
Can you also show output of ‘ping www.google.com’ in both cases.

@gerry666uk ifconfig was deprecated in 2011. The man pages for ifconfig also state that it’s obsolete. I would suggest not to ask for output from an obsoleted tool set.

@Smoky please provide the output from the following commands:

ip a
ip l
ip r
ip -6 r
firewall-cmd --list-all --zone=... (replace ... with whatever zones you are working with)
nmcli c s
nmcli d s
nmcli c s ppp0
nmcli c s enp2s0
nmcli c s enp3s0
sysctl -a | grep -E 'forwarding'

Unfortunately I cannot upload a .txt file. So this is getting a long post.

I’ve had issues with Network Manager if the connection wasn’t allowed for all users to connect to this network. The GUI Network Manager under the general tab has an option for this. If you use nmtui there is an option “available to all users” you can select this. Which meant I had to login first before I would see my machine. Maybe this could be the same thing since as you login it starts to work? As soon as I enabled that option, I no longer had to login before seeing my machine on the network.

Add to that the fact that there is pppoe in the equation (although it does not seem to be keyed to user).

I think we can close the case. I changed the parameter as suggested by iwalker and it works!
Fabolous!
Thanks
