Shared server rack in the GLRC as of 2026-02-20. Starting below the yellow Google server, the servers are (from top-to-bottom): Ravioli, Lasagna, Shell, Kurisu, Okabe, Daru, Luka, Mayuri, Maho, Leskinen, Mirrors.

Kurisu, Okabe, Daru, Luka, Mayuri

All nodes in the LUG Proxmox Cluster to run VMs for services.

Current services run by VMs in the cluster include:

LUG Homepage
IRC server
LUG IRC<->Discord<->Matrix Bridge (old bridge)
This Wiki
Matrix server (soon)
Other miscellaneous internal LUG services (PXEboot, LDAP, etc)

Nodes run Proxmox, and all VMs run Debian.

All nodes and VMs sit behind OPNSense and do not have public IP addresses or domain names.

Lasagna, Ravioli

Router/firewalls. Responsible for:

DHCP, DNS, NAT for Server LAN
DHCP for OOB LAN (no internet, restricted from Server LAN)
Wireguard VPN ingress
CARP for public services and internal network redundancy
Port-forwarding traffic to VMs in Proxmox cluster

Runs on OPNSense.
