If this post is not authorized on a Kubuntu site, please let me know. If there was a Server forum page on this site, I'd post it there, but I suppose it's unnecessary to use Kubuntu for a headless server.
So I'm still configuring my Ubuntu Server (US) 18.04.1 LTS with SSH, Samba, Webmin, and OpenVPN. The server is running on a Supermicro X9SCM-F mobo. This mobo has 3 LAN ports: 1, 2, and IPMI. ifconfig returns only the lo, loopback port. I removed the cover of the server and watched the 3 ports as I booted the server. When the mobo powers up, all 3 ports are active. During boot up, there's some time when none are active, then they come back active again. After the OS is up and running, LAN2 goes dark (no winky-blinky lights) and ifconfig doesn't "see" any of the ports. I have access to IPMI, but not LAN1 and both of those ports appear to be active.
Because the LAN2 port is active when the board powers up and doesn't go dark until the OS is up, I think it's a SW issue, but I can't imagine what it could be. Any help or links would be most appreciated.
