NethServer Version: 7.2009
I have encountered a very frustrating problem: Nethserver has cut all ethernet connectivity. I cannot access the GUI to troubleshoot; I am stuck in CLI.
The ethernet card is RTL8125, for which I have installed the correct driver. I had the ethernet connection working fine up to yesterday. The GUI alerted me to one of my DNS hosts not responding. It then cut out after I began a system backup to Backblaze.
The only change in my network is a new ISP. I switched to TekSavvy (a Canadian provider) in order to open port 25 for e-mail. That switch required me to get a DSL connection with PPoE access. Nethserver appears to have automatically conigured PPoE, despite it not being instructed to make such a connection.
So far, I have attempted to reset the network configuration using network-recovery. I have also manually disabled the PPoE connection and my wireless device, so that the ethernet device is the only available external interface. Neither of these actions helped.
When I run nmcli dev status, I get:
enp5s0 ethernet unavailable --
When I run db networks show, I get:
enp5s0=ethernet bootproto=static ipaddr=192.168.0.160 netmask=255.255.255.0 network=192.168.0.1 onboot=yes role=green wlp3s0=ethernet role=

I am going to be porting my installation off of the current computer to other hardware with a much older network card. This will hopefully solve my networking problem. In order to port the installation, however, I first need to resolve the network issue so that I don’t inadvertently wreck my new system.
Any ideas what could be done?
