Tableau + syslog-ng - Let's the story begins

In Linux world, syslog has been doing a great job logging most of system and user activities. However finding information from log is not easy at all. With so much data in the log files, it can be a daunting task to just understand the log. 

So with Tableau + syslog-ng, I decide to begin my journey of telling the story from log files. I called this project LogStory. 

This first visualization is capturing when the user login, logout and the duration spent in the session. It will also show when the session is active and refreshed every 3 second. 



You can view it live in http://tableau.fosstech.biz/ServerConn.html

What story should I tell next ?

SLES 15 LVM + XFS Without Separate /boot Partition

Image
GRUB2 allow booting from LVM partition, however I haven't see any documentation on how to setup SLES 15 using LVM + XFS root partition without separate /boot partition. You can even put /boot as one of the logical volume. When separate /boot partition is not created, we will need to create small partition with BIOS boot flag and once this BIOS boot partition is created, you can setup the remaining disk as LVM partition and setup your volume group and logical volumes as usual.    During the installation, choose "Expert Partitioner" > "Start with Existing Partitions". Select your disk and "Create New Partition Table" > "GPT" Select "Partitions" tab and choose "Add Partition" Choose "Custom Size" then enter "8 MiB" as the size. The Role of this partition should be "Raw Volume (unformatted)" Select BIOS Boot as Partition ID Create another partition as LVM pa...

Docker Rootless on Ubuntu (2026 Guide)

Image
Quick one-liner: All the container power, none of the root-level risk. Why This Matters When I first started with Docker, I ran everything as root. It was easy, it worked, and I didn't think twice about it. Then I learned that a container escape vulnerability could give an attacker full root access to my entire system. That's when I switched to rootless Docker — and you should too. Rootless Docker runs the Docker daemon entirely under your regular user account. No sudo required. No root privileges for container operations. If a container gets compromised, the attacker is stuck with your user's permissions — not root. You asked, I delivered: This guide was the #1 request in my LinkedIn poll (Ubuntu/Linux Mint won with 50% of votes). Planning Disk Space In rootless mode, Docker stores all images, containers, volumes, and build cache under your home directory at ~/.local/share/docker . This means your home directory needs enough space to hold every...

pfSense and scp

pfSense and scp doesn't play nice. When you try to scp to admin@pfsense.hostname you will likely encounter the error " Illegal option -[X] " The solution to this is rather simple too, when running scp to pfSense, just use the root account.  Cheers
