hostmask on an ip address can affect jail DNS

Leave a Comment / DNS, iocage, Jails, named, py-iocage / By /

I encountered, and later solved, a DNS issue on a FreeBSD jail. The jail is my web proxy, of sorts. I have one public IP address, which is dynamic (not relevant, but mentioned only in passing) so all incoming web traffic goes to a single internal RFC-1918 IP address. From there, nginx does reverse proxies out to the various hosts: devgit.freshports.org dev.freshports.org test.freshports.org stage.freshports.org There are more, but you get the idea. Each […]

Unintended shutdown of the #homelab

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

Today was battery replacement day at my place. The UPS batteries were replaced without downtime. That doesn’t mean there wasn’t downtime. I am not documenting this in real-time. This is post-event analysis. First, I wanted to change the battery replacement date, so I ran acptest on the pfSense server, to which the UPS is connected to.

Converting an iocage jail from vnet

Leave a Comment / FreeBSD, iocage, Open Source, SamDrucker / By /

There are known problems with vnet and firewalls. I’ve been plagued by such issues for months. In this case, my git jail, I’m giving up and moving away from vnet jails. This post documents how I did this. Get the IP address Make sure you know the existing IP address of that jail. It might be defined within the jail, via /etc/rc.conf. It might be in the jail configuration. I ssh‘d into the

starting service would freeze the terminal session

I noticed a problem with a newly-created freshports daemon script: starting it would sometime freeze the terminal session. The rc.d script The rc.d script was fairly straight forward: Nothing odd there, right? This first happened a week or so ago. I moved on it and decided to look into later. But wait, there’s more This issue came up again today. The system would be processing incoming commits and it would hang. It would

Creating a new iocage jail

Every time I go to create a new iocage jail, I cannot remember out the command. Here we go, for next time: iocage create -n devgit-ingress01 –thickjail host_hostname=devgit-ingress01.int.unixathome.org ip4_addr=10.0.0.141 –release 12.1-RELEASE iocage create -n devgit-nginx01 –thickjail host_hostname=devgit-nginx01.int.unixathome.org ip4_addr=10.0.0.147 –release 12.1-RELEASE

Renaming and replacing zroot filesystems using mfsBSD

Leave a Comment / FreeBSD, General, Open Source, ZFS / By /

I am replacing one zroot with another because of missing binaries and suspect layout. The existing zroot is an old system predating current zroot layouts. This work is being performed on a test system (that link is not safe for young eyes). In this post: FreeBSD 12.1 mfsBSD 12.1 The failed attempt I tried once, and failed, with with old zroot_old and new zroot_new mounted. zroot_new became unusable and I started again. This

Burning a disk image to a thumbdrive on OSX

Leave a Comment / Open Source, OSX / By /

Every time I go to burn a new image to a thumbdrive I have to remember how. This post aims to fix that so I can just look it up. Case in point: mfsBSD I have downloaded mfsbsd-12.1-RELEASE-amd64.img from https://mfsbsd.vx.sk/files/images/12/amd64/ From the same URL I’ve looked in mfsbsd-12.1-RELEASE-amd64.img.sums.txt and grabbed the md5 hash. I verified the downloaded file via: [dan@pro02:~/Downloads] $ md5 mfsbsd-12.1-RELEASE-amd64.img | grep a79046a330938d284167dac08cc0bfcb MD5 (mfsbsd-12.1-RELEASE-amd64.img) = a79046a330938d284167dac08cc0bfcb Yes, that matches.

replacing an existing zroot with a proper zroot

Leave a Comment / bectl, Disks, FreeBSD, hardware, Open Source / By /

I wrote this post late one night while pondering how to solve this problem. I may have solved it with much less effort. I want to copy a zroot from old drives to new drives. The new drives are in a test box of mine. Once the new drives are configured, I will replace the existing mirror with them. Not shown here, I have already installed FreeBSD 12.1 on the new drives. I

ZFS: adding a drive back into the zpool

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

Today I was updating some servers. One of them was rebooted three times. On the third time, one of the drives went missing. This is how I tracked down which drive, and which slot in the server, and fixed it. I’m writing it mostly so I can remember how to flash the light on the drive. There is also an off-by-one issue to avoid. In this post: FreeBSD 12.1 sesutil ZFS Supermicro 846
