    Proxmox cluster (3 nodes) unreachable GUI after power outage

    I'll get it done after finals and before my doctor's appointment later this week. I have a good feeling it is my managed switch. Edit: It is my managed switch. Brought Node #3 online that has NIC-teaming. Node #1 still isn't working. So during the weekend i'm going to restore to default network...

    Has anyone configured SecurityOnion for Proxmox/KVM?

    Hello! I configured SO a week ago and I was spending time monitoring alerts and monitoring my family's devices and trying out Red/Blue team exercises on TryHackMe, HackTheBox, and VirtualHackingLabs, but I just found this post again in my email. I put together a writeup for configuring...

    Has anyone configured SecurityOnion for Proxmox/KVM?

    So I added the two virtual NICs as required by SecurityOnion (one is a sniffer interface and another is a management interface). But when I get to the network configuration page I get this error. I believe the problem is that Proxmox is automatically assigning IP addresses via DHCP to...
