Initializing n8n process n8n webserver failed, exiting The fix is to add this line -e N8N_LISTEN_ADDRESS=0.0.0.0 In my case, the problem was that IPv6 was disabled in my kernel. Since at least version 1.107.4, the default listen address is ::. sudo docker run -it –rm \ –name n8n \ -e GENERIC_TIMEZONE=”America/New_York” \ -e TZ=”America/New_York” \ -e N8N_ENFORCE_SETTINGS_FILE_PERMISSIONS=false \ -e N8N_RUNNERS_ENABLED=true \ -e N28N_SECURE_COOKIE=false \ -e N8N_METRICS=true \ -e N8N_LISTEN_ADDRESS=0.0.0.0 \ -e QUEUE_HEALTH_CHECK_ACTIVE=true \ -v ./n8n_data:/home/node/.n8n \ docker.n8n.io/n8nio/n8nRead More →

Let’s walk through how to extract meaningful fields like IP address, port, error level, and message content from a raw PHP warning log using regular expressions and Splunk’s rex command.

I recently picked up an older HP 880 gaming desktop and noticed something odd: it came with a 32GB NVMe drive pre-installed, and no other storage device was present. Naturally, I tried installing Windows directly onto the 32GB NVMe, but the installer couldn’t detect it at all. That was my first clue something was off. To proceed, I installed a standard hard drive and successfully installed Windows there. Interestingly, during the installation process, the system still didn’t show the 32GB NVMe as a usable drive. So what’s that mysterious 32GB module actually doing? That’s when I noticed something impressive—this system boots incredibly fast. I’m aRead More →

This was my first visit to Harpers Ferry. Before coming, I tried to find some brief information about the area, but most of it wasn’t very helpful. So, I decided to write this short note to share my experience: What’s the main spot to visit?The highlight of the trip was the overlook point I marked on the map. From there, you get a great view of the bridge and can walk across it toward Maryland Heights. It’s definitely worth seeing. Parking OptionsThere are three main parking areas: Parking Fee:The fee is $20 for 3 days. If you’re at the visitor center, you can pay there.Read More →
