freebsd

I just found out that FreeBSD 13.2-RELEASE will be end-of-life support within 1 month time from now. It’s time to upgrade FreeBSD on one of nas boxes to 14.0-RELEASE. The following is to capture the steps used to perform the upgrade. It’s similar to my old post. SSH into the server, and run tmux or screen. You really don’t want to lose SSH connection during the upgrade. $ ssh kenno@nas2 $ tmux Check the current running version of FreeBSD: root@nas2:~ # freebsd-version 13....

FreeBSD 14.0-RELEASE just got relesed at the end of last month, and I wanted to upgrade my NAS server running FreeBSD 13.x-RELEASE to 14.0. Using the installation instruction from [1], I was able to upgrade smoothly without any issues. Here are the steps: # freebsd-update fetch # freebsd-update install # freebsd-update upgrade -r 14.0-RELEASE # freebsd-update install Reboot: # reboot After rebooting, freebsd-update(8)[2] needs to be run again to install the new userland components:...

I recently got IPv6 running at home, with most devices including my iPhone happily get an IPv6 assigned. My NAS running FreeBSD13.2 currently only has an IPv4 assigned, so I’m going to configure IPv6 for it too. I’m still new to IPv6. The way I have it setup on my router, running OPNsense, is to set the “Router Advertisements” to “Unmanaged” with DHCPv6 disabled. “Unmanaged” for SLAAC (A flag), and SLAAC stands for Stateless Address Autoconfiguration....

I feel upgrading FreeBSD from 13.0 to 13.1 is so minor that it might not worth a blog post. The thing is, I just did this upgrade on one of my 2 nas servers a month ago, and now I forgot how to do this already. This post should be short, and I will include the reference(s) at the end if you’d like to learn more about this update process....

A quick note for me to remind myself how to stop/start network service on FreeBSD (13.0). To stop or start, run one of the following commands: # service netif stop # service netif start To restart, just replace stop or start with restart: # service netif restart I also just found out that the above commands will nto restarting the routing service, as they only stop/start/restart network. To restart the routing service on FreeBSD, run:...

Recently, I found out that the ZFS pool on a FreeBSD is running out of space. There is no option to clean up this storage, but there are spare disks. So the next logical thing to do is to add 2 extra disks to the existing (mirror) ZFS pool. This FreeBSD server is a virtual machine (VM), and after attaching 2 physical disks to this VM, I had difficulty identifying these disks....

It’s been quite a while since I last posted something here. It’s not that I haven’t come across many issues in tech, it’s just that I haven’t had enough time to write anything. So I’m going to share how to easily clear the ZFS metadata on a disk previously used in a ZFS pool. Here is an example - I have an external drive, and it is detected as /dev/da0 when plugged into a FreeBSD server....

What was your first text editor when you started using Linux/Unix? Mine was pico. It was very easy to get started with and quite similar to nano. Then I moved to emacs and sticked with it for a long while. Eventually, I’ve switched to vim (or neovim), and that’s what I have been using until now. Well, the thing about text editor or may be this also applies to many other things, you’re only familiar with features that you constantly use....

I wanted to install vim package on FreeBSD 13.0, and did so without realizing that there were over 86 additional dependency packages installed. This was done with pkg install -y vim command. Anyway, I wanted to clean up by removing vim and those dependencies after all this is a headless server. Removing vim package doesn’t remove the installed dependencies. Fortunately, I was able to copy and paste the names of dependency packages and save it to a file....

While creating a new user account on one my servers running FreeBSD 12, I encountered the following error: root@nas2:~ # adduser Username: devops Full name: Ansible Operator Uid (Leave empty for default): Login group [devops]: Login group is devops. Invite devops into other groups? []: Login class [default]: Shell (sh csh tcsh nologin) [sh]: Home directory [/home/devops]: Home directory permissions (Leave empty for default): Use password-based authentication? [yes]: no Lock out the account after creation?...
