blackbox Host Configuration

Create zpool10 Storage Pool The host's rpool (default ZFS pool used by Proxmox) can be used for templates and whatnot but I want a big pool for storing all my data. So I created a ZFS RAIDZ2 pool using 6x 10TB HDDs. This is the command I used to build my ZFS...

PCI Passthrough

Linux KVM Virtual Machines

Ensure IOMMU Is Activated First step of this process is to make sure that your hardware is even capable of this type of virtualization. You need to have a motherboard, CPU, and BIOS that has an IOMMU controller and supports Intel-VT-x and Intel-VT-d or AMD-...

Configuration Because I don't want my main management interface to ever change names, I explicitly give it a name based on its MAC address. # /etc/systemd/network/10-management-net.link + [Match] + MACAddress=70:85:c2:fe:4c:b7 + + [Link] + Name=man0 ...

Common Software

mini Host Configuration

Install fail2ban This blocks connections that make repeated failed attempts to authenticate. SSH is covered by default which is what I am interested in, and I'll add additional config to similarly block too many repeated auth failures against the Proxmox web ...

Setup PCI Passthrough

mini Host Configuration

See PCI Passthrough for more detail as to why I am doing these things. Proxmox doesn't need a GPU, so blacklist the GPU and prepare it to be passed for a guest machine. Enable Kernel Modules # /etc/modules # /etc/modules: kernel modules to load at boot tim...

LXC GPU Access

Linux LXC

Giving a LXC guest GPU access allows you to use a GPU in a guest while it is still available for use in the host machine. This is a big advantage over virtual machines where only a single host or guest can have access to a GPU at one time. Even better, multipl...

Multiple Origins

Git

Pushing to multiple origins ensures that a repo is always available. While I use Gitlab as my main repository, I might want to mirror it to Bitbucket, Github, or another GitLab for redundancy. As an example, if my server ever needed to be rebuilt it would be ...

Export Variables From a File

Shell Bash

If you store environment variables in a file and want to quickly export all of them it is actually not as simple as running an export on each line. # source $MY_FILE # export $(cut -d= -f1 $MY_FILE) source Another thing you can do is update ~/.bashrc or ...

Force Client to Use Password Authentication

SSH

Key authentication should always be setup, but sometimes it is necessary to authenticate using passwords—even if for nothing else than to verify passwords are disabled. ssh -o PreferredAuthentications=password -o PubkeyAuthentication=no user@domain.com sou...
