basti

This is going to be a higher-security network services host, mostly to host LDAP and maybe some associated services.

Build notes

This is a mix of notes from the previous provisioning, plus what I did when I renamed her from krolik to basti. I did this build around 2026-05-18

Build a clean Alma10 system than add FreeIPA to it.

rename krolik to basti

basti 300 IN A 192.168.53.10

Prepare network

This will live in a new VLAN, attached to hoshino, with firewalling eventually added.

Prepare hoshino:

Prepare bridge
- VLAN 20, INFRA
- Bridge VLAN on bridge1 (ports Et1-6)
- Untagged on port 5,6 (amaris, basti)
Create interface-VLAN
- name VLAN20_INFRA
- on bridge1
Add an IP address on the VLAN
- 192.168.53.1/24
- network 192.168.53.0
- on interface VLAN20_INFRA
Prep DHCP server on hoshino for the build, create the Network
- address 192.168.53.0/24
- gateway 192.168.53.1
- mask 24
- DNS server 8.8.8.8
- domain thighhighs.top
- next server 192.168.1.25
- boot file name grub/grubx64-improved.efi
Create an IP pool for it
- name: INFRA
- addresses: 192.168.53.10-192.168.53.30
- next pool: none
Create a DHCP Server for the segment
- name: infra
- interface: VLAN20_INFRA
- address pool: INFRA
Update DHCP lease for basti to give correct address
- address: 192.168.53.10
- MAC: E8:FF:1E:D5:60:7A
- server: infra

Boot it up and hope it works!

Do firewalling on hoshino:

We can't use in/out ports because it's part of the bridge, and we don't want to enable ip-firewalling on the bridge because it'll slow it down, so we'll just use src/dst IPs for now.
Google this error for details: "in-bridge-port matcher not possible when bridge use-ip-firewall is disabled"

OS imaging

We're now using servers/neru to serve TFTP and HTTP for PXE boot, no need to have a whole linux machine dedicated to it. Slightly harder to maintain, but should be more bulletproof and doesn't need as much maintenance. A USB stick hosts the bootloader and configs for TFTP, and we run nginx in a container to serve netinstall images from the same directory (/usb1p1/srv/)

Editing kickstart configs is kinda a pain in the arse now because you can't just run vim on the device, but you can edit remotely via an SSHFS mount.

What do we want to even install here anyway?

dnf install mtr traceroute

FreeIPA

Start on the QSG: https://www.freeipa.org/page/Quick_Start_Guide

TBC

MikroDash

This is kinda nice.

Run it like this:

docker run -d -p 3081:3081 -v /persist/mikrodash:/data --name mikrodash --restart=unless-stopped ghcr.io/secops-7/mikrodash:latest

iscsi notes

basti attaches iscsi LUNs from fenny so it doesn't need much local storage.
