Adding 32 GiB of RAM to Lenovo ThinkPad P1 G6
At ${WORK}, we ordered one Lenovo ThinkPad P1 G6 (P/N 21FV000MMX) which came with 32 GiB of RAM. This laptop has two slots for memory modules, so we ordered and waited on one additional 32 GiB memory module.

For some reason a rebooted Security Onion manager node is perceived as a combined manager-search node (this is my hypothesis), filling up the /nsm filesystem with unnecessary, large amounts of data. Here are four shell scripts I find useful.

When the harddrives in the oldest virtualization server at $WORK died, I was virtually left without any test systems running the other BSDs and some select Linux distros. We have another virtualization server with plenty of resources, and I decided to try NetBSD/amd64 10.0-RELEASE, build a few packages, and upgrade the VM to 10.0-STABLE.

Autodesk recently published the 2025 editions of their products. Most notably this time, with the exception of 3ds Max 2025, is that the file numbered 001_002 is a short .exe file, while the file numbered 002_002 is a complete 7-Zip archive.

While following the suggestions of https://github.com/jtesta/ssh-audit/wiki/FreeBSD and security/py-ssh-audit 3.2.0, I figured it’s better to make adjustments to the startup script in libexec/rc/rc.d/sshd.

I decided to play with FreeBSD 13.3-RC1 in VirtualBox. My display is capable of 1920×1200, and we must specify this both in the VirtualBox XML file for the guest and in the guest’s /boot/loader.conf. The font specification goes in the latter file.

We upgraded our Security Onion nodes today. We really had no choice. I was surprised to see the so-elastalert container normally running on the manager being unable to start. I happened to glance at the release notes, and tried the commands suggested there. Suffice it to say, I got nowhere.

In the aftermath of KB5034441, I experimented with creating a 1 GiB large Windows Recovery Partition on a new Microsoft Windows 10 VM, ensuring enough free space for KB5034441 and hopefully any later versions of the “Windows Recovery Environment.”

If Zeek on your forward node (sensor) keeps restarting and its detailed status never changes from “health: starting,” to simply “healthy,” have a look at zeek.config.networks.HOME_NET in the Grid Configuration.
