Creating a wireguard connection between my home and colo – failed attempt

Leave a Comment / FreeBSD, wireguard / By /

NOTE: I wrote this, got stuck, then went a slightly different direction: I stopped using wg set Instead, I updated the configuration files directly I was not satisfied with the wg approach Although it is great for modifying things on the file, I don’t think it helps novices learn Wireguard I’m leaving it here anyway. Please use Creating a wireguard connection between my home and colo instead. None of these keys/IP addresses are […]

How I configure dma for mail delivery in jails on my internet hosts

Leave a Comment / dma, Mail / By /

This is based on a series of tweets which I now want to place into blog post. When I go searching for something I’ve done before, I usually check my blog first. dma is “is a small Mail Transport Agent (MTA), designed for home and office use. It accepts mails from locally installed Mail User Agents (MUA) and delivers the mails either locally or to a remote destination. Remote delivery includes several features

mps0: IOC Fault 0x40007e23, Resetting

Here I am, sitting on a beach, writing a blog post, and sipping a cool adult beverage. Reading email. I see this: I quickly ssh into the host to check zpool status: Lines 15-17 are relevant. There was a resilver event, which completed at 08:49:48 The vdev state changed event occurred at 08:49:34 That all seems to tie in, time-wise. More info than you want This displays vdev guids: Line 11 shows the

logcheck – egrep: trailing backslash (\)

Leave a Comment / FreeBSD, Open Source / By /

When updating to FreeBSD 13.1, I started getting these messages from sysutils/logcheck: egrep: trailing backslash (\) This post will document how I tracked down the problem. It is occurring on several hosts. In this post: FreeBSD 13.1 logcheck-1.3.24 Other similar issues I suspect the issue arises because of the change from egrep 2.5.1 under FreeBSD 12.3 to egrep 2.6.0 under FreeBSD 13.1. After the upgrade, I also encountered some egrep: empty (sub)expression messages

I forgot to enable compression on ZFS

Leave a Comment / ZFS / By /

I forgot to enable compression on this FreshPorts node. I have no idea why/how. After doing this, I went to a directory with a lot of space and copied stuff around. [aws-1 dan /jails/ingress01/var/db/freshports/message-queues/archive] % sudo mv 2021_03.tar.gz 2021_03.tar.gz.tmp 21:01:28 [aws-1 dan /jails/ingress01/var/db/freshports/message-queues/archive] % sudo mv 2021_03.tar.gz.tmp 2021_03.tar.gz 21:01:38 That will free up *some* space. But really, most of this zpool really needs to have zfs send | zfs recv done on each

Making my pkg.conf configuration version independent

Leave a Comment / FreeBSD, Open Source, pkg, poudriere / By /

In this post, I will talk about how I modified my pkg configuration so I don’t have to modify it after upgrading a host/jail from one version of FreeBSD to another. You might say that you don’t have to do that. Perhaps you have a different configuration and aren’t doing what I’m doing. HEADS UP: I hit a problem with this approach when updating a jail using mkjail: see https://github.com/mkjail/mkjail/issues/30 In this post:

freebsd-update fetch install -> Cowardly refusing to proceed any further.

Removing an old condensate pump

Leave a Comment / House / By /

I bought a house. Yesterday was the settlement. I gave away some money, got a deed, and now I have a mortgage. Last night was an empty house party for a small group of friends and new neighbors. This morning I had a walk through the house with a finishing carpenter who is now retired. He was helpful in my learning about broken window mechanisms, door repair, ceiling patching, providing contacts for a

Monitoring FreeBSD jails from the host

Leave a Comment / FreeBSD, Jails, Nagios, Network monitoring, nrpe / By /

It was May 2021 when I tweeted about monitoring FreeBSD jails which had jail IP addresses only in the 127.0.0.0/8 range. Yesterday, nearly 6 months later, I did the first test of this. This came up because I’m getting a new FreshPorts node ready. I’ve created a file in the jail to be run from the host. That script runs in the jail but it initiated by a process on the host. In
