Missing dependencies from mail/mailman3

Leave a Comment / Mail, Mailman / By /

This started off as a migration. It went down a rabbit hole of incorrect and undeclared dependencies. I’m going to post this as documentation for the required ports update. I’m migrating from Mailman 2.1 to Mailman 3 not because I want to but because Python 2.7 is deprecated. I’m sick of seeing these monitoring messages: In this post: FreeBSD 12.1 mailman-2.1.34 (source) py37-mailman-3.3.1 (destination) Snapshots I’m taking a snapshot of this FreeBSD iocage

Hosting multiple web servers behind a single IP address

Leave a Comment / FreeBSD, nginx, Open Source / By /

Virtual hosts for a website are a thing. One webserver can host multiple websites. They can all be on the same IP address, different IP addresses, different ports, etc. This post is about using a proxy service. Before I started with this solution, at home I hosted every website on the same server. My firewall would redirect incoming ports 80 and 443 to my webserver, and Nginx/Apache would take care of the rest.

Using split DNS for websites hosted locally

Leave a Comment / DNS, named / By /

The dev.freshports.org website is hosted on server in my basement. For you, that IP addresses resolves to a publicly available IP address. For me, that IP address resolves to an RFC 1918 address: $ host dev.freshports.org dev.freshports.org has address 10.55.0.24 Sometimes this is referred to as split dns, also known as split-horizon DNS, split-view DNS, split-brain DNS, or a fricking stupid thing to do). How? I have a DNS zone file at home

Recalibrating an APC UPS

Leave a Comment / FreeBSD, LibreNMS, UPS / By /

This work was done in August. Since then, I have replaced the APC with an Eaton 5PX, and I am much happier. This might make for interesting reading, but that depends on how bored you are.. Following on from my failed calibration attempts, I thought I would try it again this morning before work. In this post: APC UPS SUA2200RM2U with a AP9619 Network Management card LibreNMS 1.66 FreeBSD 12.1 Before It’s 1132

Restoring your non-Apple Time Capsule from your Mac

Leave a Comment / OSX / By /

I have written about backing up your MacBook to a ZFS-based Time Capsule. Today, I restore. I am setting up a laptop to be just like my other laptop. This is not a disaster recovery incident, but it could be. In this post: The laptop is on the same network as the time capsule host (i.e. no VPN). The laptop is on a wired network – not required, but I think that would

I have these boot drives, I want to copy them to another. They both happen to be zroot and bootable. I booted from mfsBSD and imported both new and old zroot, using the pool ID shown by zpool import -N. root@mfsbsd:~ # zpool import -N pool: data01 id: 2668514456528412656 state: ONLINE action: The pool can be imported using its name or numeric identifier. config: data01 ONLINE mirror-0 ONLINE gpt/S59VNS0N809087J_S00 ONLINE gpt/S59VNJ0N631973D_S01 ONLINE mirror-1

In this post, I am creating a 4 drive ZFS pool consisting of two mirror. In this post: I’m booting from mfsBSD 12.1 ZFS Creating partitions On FreeBSD, it is convention to create partitions. It is not necessary, but I don’t use all the space in case a future replacement drive is slightly smaller than these drives. NOTE: I am not, but have not confirmed that this is no longer a problem in
