Echo6 Environment Reference

Proxmox Cluster (echo6-cluster)

Five nodes running Proxmox VE:

Network Notes

  • media NIC: Original Intel e1000e NIC crashes under sustained NFS load — replaced with USB Realtek RTL8153 GbE adapter on vmbr0
  • Tailscale dns bootstrap: All LXC containers with Tailscale have a systemd drop-in (/etc/systemd/system/tailscaled.service.d/dns-bootstrap.conf) that ensures fallback DNS exists before tailscaled starts, preventing chicken-and-egg DNS resolution failures on reboot

TOC Node Details

  • Hardware: Intel i9-10900X (20 threads), 64GB RAM (4×8GB + 2×16GB DDR4), 512GB NVMe, RTX A4000
  • GPU: Passed through via VFIO to VM 150 (cortex), not used on host
  • VMID ranges: 100-149 (LXC), 150-199 (VMs)
  • Presave backup: /home/zvx/toc-presave/ on Contabo (1.8G) — contains old Ubuntu config

IdahoMesh Headscale Node List

Separate Headscale instance on CT 106 (192.168.1.106), prefix 100.100.0.0/16. Reachable from echo6 tailnet via mesh-bridge (CT 107).

Node Tailscale IP User Type
mesh-bridge 100.100.0.3 malice LXC (bridge)
burley-butte 100.100.0.1 nebra Pi (offline)
mt-isr 100.100.0.5 nebra Pi Zero 2 W

SSH Access

Standard user: zvx Credentials: Source from /home/zvx/projects/.ref/credentials

Most servers use SSH key auth. Exceptions noted below.

# SSH to any server (key auth)
ssh zvx@<ip-address>

# Examples
ssh zvx@192.168.1.244  # TOC (Proxmox host)
ssh zvx@192.168.1.150  # cortex VM
ssh zvx@192.168.1.241  # utility Proxmox
ssh -i ~/.ssh/contabo2_ed25519 root@5.189.158.149  # edge1 (mail-only; formerly Contabo)
ssh zvx@cortex         # cortex via Tailscale hostname
ssh edge2              # edge2 via SSH config alias (admin@100.64.0.26)

edge2 SSH access

edge2 is hardened: PasswordAuthentication no, root login disabled. SSH user is admin with passwordless sudo. The SSH config alias edge2 maps to admin@100.64.0.26.

Authorized keys on edge2 (/home/admin/.ssh/authorized_keys):

  • echo6-contabo2-184.174.35.153 — the original provisioning key (cortex ~/.ssh/contabo2_ed25519)
  • cortex — cortex default id_ed25519
  • matt-desktop-wsl2 — WSL2 default key
  • cookie-sync — Windows native SSH key

To access CTs on edge2: ssh edge2 then sudo pct exec <vmid> -- bash.

Password-auth hosts

These require password authentication (no SSH keys installed):

Host User Password Access
aida-nebra zvx 7redditGold sshpass -p '7redditGold' ssh zvx@aida-nebra
mt-isr isr UfPsfwyMIUIKb1 sshpass -p 'UfPsfwyMIUIKb1' ssh isr@192.168.1.141
mt-burleybutte bb (see credentials) sshpass -p '<pw>' ssh bb@192.168.1.185
matt-desktop administrator Qw1290opzx ssh -o PreferredAuthentications=password -o PubkeyAuthentication=no administrator@192.168.1.254
toc root 7redditGold sshpass -p '7redditGold' ssh -o PubkeyAuthentication=no root@100.64.0.13

Use the Tailscale hostname (aida-nebra) or local IP (192.168.1.253) — both work for aida-nebra. mt-isr is on IdahoMesh tailnet (100.100.0.5) — reachable from echo6 via bridge. matt-desktop is accessible via local IP (192.168.1.254) or Tailscale (100.64.0.10) — requires explicit password auth flags.
