I planned to create a zroot mirror when I installed FreeBSD on the R720 but the supplier shipped only one of the two purchased SSDs. Today the second drive arrived. Let’s create a zroot mirror. In this post: FreeBSD 12 man 8 zpool Posts I looked at: creating a mirrored ZFS Pool out of a single-disk rpool – not FreeBSD Convert Single disk ZFS-On-Root to Mirror – used the GUID via zbd; I

I have obtained a Dell R720 containing 10 x 400GB SSDs. The drives are connected to a RAID controller (H710P) which cannot do JBOD / IT mode. This means the drives are effectively hidden from ZFS, which is never good. In this post: FreeBSD 12.0 ZFS Dell R720 SAS 9207-8i This post describes past work and future plans for this server as I get it ready to be a general purpose server running

I have scripts for monitoring vulns in FreeBSD jails. They use third-party scripts. All I wrote was the Nagios part of the solution. I was preparing slides for my Why I prefer thick jails over thin jails talk at EuroBSDCon 2019. There is still time to register and attend. I was explaining my scripts and was providing links to gist.github.com … I realized I should create a repo: https://github.com/dlangille/freebsd-nagios-jail These scripts do the

zi0r suggested I use hooks to accomplish my patches-outside-distfiles question. In this post: FreeBSD 12.0 poudriere 3.3.2 I started reading the documentation and played with the supplied sample files in /usr/local/etc/poudriere.d/hooks. For background, see FreeBSD custom port patches when using poudriere. Eventually I came up with this solution: mkdir during the start phase mount during the mount phase I put stuff into a gist first, then created this post. The hook This is
I was asked why I was exasperated with iocage: This is the list of issues where I found my name. A given issue may be listed multiple times. Oct 2017 – iocage upgrade is looping: https://github.com/iocage/iocage/issues/399 Jun 2018 – cannot run ‘iocage start’ from my home dir: https://github.com/iocage/iocage/issues/567 Aug 2018 – entries in fstab disappear: https://github.com/iocage/iocage/issues/595 Dec 2018 – Cannot install 12.0 in a jail: https://github.com/iocage/iocage/issues/715 Jan 2019 – iocages puts exec files
I went and did a thing. I ported OwnTrack Recorder to FreeBSD. In this post: FreeBSD 12 owntracks/recoder 0.8.4 I refer to owntracks/recorder as ot-recorder. The FreeBSD service is known as otrecorder On FreeBSD, ot-recorder runs as the ot-recorder user, created by the package. I did not want it running as root. ot-recorder installs mosquitto by default, because it needs it’s libraries. That is also the reason why it installs curl. I chose

When upgrading to LibreNMS 1.53.1, your website will not load. You’ll see a message saying check the logs. There will be nothing useful in the logs. I checked. Nothing. This is how I fixed the loading issue. In this post: FreeBSD 12.0 LibreNMS 1.51 running in a jail Upgrading to 1.53.1 First attempts Running as www OK, let’s run that as www. Eh? What?

Today is the day after BSDCan 2019. The power cables and extension cords from the hacking lounge have been laid to rest in an Ottawa basement until next year. Sitting in my parents garden, I noticed some Nagios cert warnings: I logged into my certificates server (the website from which all my hosts download their certs). The cert looked OK: [dan@webs01:/usr/local/www/certs.unixathome.org/www/certs/x8dtu.unixathome.org] $ ls -l total 14 -rw-r–r– 1 rsyncer rsyncer 1647 May 11
I’ve been making use of some FreeBSD-provided scripts within my Nagios monitoring. Recently, I started seeing a problem after some jail maintenance. This post is about that problem and the fix. Full disclosure: the issue was not what I thought it was and I did not solve it. I’m using: FreeBSD 11.2-RELEASE-p9 The scripts are: 405.pkg-base-audit 410.pkg-audit Where are they from? $ pkg which /usr/local/etc/periodic/security/405.pkg-base-audit /usr/local/etc/periodic/security/405.pkg-base-audit was installed by package base-audit-0.3 You don’t
