A Short IPv6 Guide for Home IPv4 Admins

This guide is for homelab admins who understand IPv4s well but find setting up IPv6 hard or annoying because things work differently. In some ways, managing an IPv6 network can be simpler than IPv4, one just needs to learn some new concepts and discard some old ones.

Let’s begin.

First of all, there are some concepts that one must unlearn from ipv4:

Concept 1

1. Install ipset:

apt-get install ipset

2. Create new ipset:

ipset create tor iphash

kern.maxproc: Maximum number of processes
kern.ngroups: Maximum number of supplemental groups a user can belong to
kern.ipc.shm_allow_removed: Enable/Disable attachment to attached segments marked for removal
kern.ipc.shm_use_phys: Enable/Disable locking of shared memory pages in core
kern.ipc.shmall: Maximum number of pages available for shared memory
kern.ipc.shmseg: Number of segments per process
kern.ipc.shmmni: Number of shared memory identifiers
kern.ipc.shmmin: Minimum shared memory segment size
kern.ipc.shmmax: Maximum shared memory segment size
kern.ipc.semaem: Adjust on exit max value

Download of kernel+initrd works on real hardware (HP/Compaq 6730b),
but this message comes up after a few seconds.

Updated guide (for CrossOver 20.0.0)

• Install dependencies: Xcode developer tools (Command Line); cmake; gcc or clang to compile C code; bison >= 3.0 (can be upgraded via homebrew); xquartz; flex; mingw-w64; pkgconfig; you might also need freetype with brew install freetype
• Make sure the right version of bison is in path: brew upgrade bison then check version and cd /usr/local/Cellar/bison/<version>/bin and export PATH="$(pwd):$PATH" then check with which bison
• Download source (CodeWeavers CrossOver FOSS version Source) and extract it (double click the file in Finder or untar it: tar -xz source.tar.gz)
• Add missing wine/include/distversion.h file with this content:

These are bare-bones instructions for creating a Windows image for bhyve on SmartOS. You will need a platform image that has the fix for OS-7117. Platform images that I've used in testing are here: iso tgz usb

Create a volume that will be the disk.

zfs create -o volblocksize=4k -V 16g -s zones/hdd-windows

This script will be used for booting from the CD.

A minor list of how to create and boot a Bhyve-zone in Joyent SmartOS

cd /opt/local/artifacts/
vim zonemanifestBhyveFreeBSD.json
vmadm create < zonemanifestBhyveFreeBSD.json
curl -kLo /zones/UUID/root/FreeBSD-12.0-RC3-amd64-bootonly.iso

The following line is for KVM, not BHYVE, hence obsoleted for non-legacy boot options

vmadm boot UUID order=cd,once=d cdrom=/FreeBSD-12.0-RC3-amd64-bootonly.iso,ahci

Windows 10 Pro

Windows 10 Pro ISO

Create a fresh Windows 10 Pro ISO file with Microsofts Media Creation Tool. (I created a Windows 10 Pro 64 bit German ISO image)

Save the created image on your SmartOS global zone.

cp ... /zones/Windows10_64de.iso
