Notice that the ping command actually returned the IP address for the Google server that it connected to, rather than the URL that was requested. This is a handy secondary application for ping, as it can be used to determine the IP address of the server hosting a website. One of the big advantages of ping is that it's pretty much ubiquitous to any network enabled device. All operating systems support it out of the box, and even most embedded devices can use ping! Have a go at the following questions. Any questions about syntax can be answered using the man page for ping (man ping on Linux).

💡 Quick IT Tip: Did you know you can flush DNS on Windows using ipconfig /flushdns? This often fixes connectivity issues without restarting your router. Simple, but effective!”

Did you know that Firefox will soon stop supporting 32-bit Linux systems? 🚨 This significant change is set for 2026 and could affect many users and developers who rely on these systems for their daily operations. Here are some key insights: - Mozilla has announced the end of support for 32-bit Linux versions of Firefox by 2026. - This move reflects a broader industry trend towards prioritizing 64-bit architectures, which offer improved performance and security. Why is this important? - As technology advances, supporting older systems becomes increasingly challenging and less efficient. - This decision aligns with the shift towards modern computing standards, ensuring better security and performance for users. What does this mean for you? - If you're using a 32-bit Linux system, now might be the time to consider upgrading to avoid future compatibility issues. - Organizations should evaluate their systems and plan for transitions to 64-bit architectures. What are your thoughts on this transition? Have you already moved to a 64-bit system, or are you planning to?

💻 Diving into Ubuntu Server at Home! I recently set up my home Ubuntu Server and had a lot of fun learning how to make it SSH-ready with a static IP. 🖥️ In my latest blog, I walk through: Finding your network interface (ens33 or enp3s0) Setting a static IP with Netplan Disabling cloud-init so your settings stick Testing SSH access remotely It’s a simple guide, but perfect for anyone tinkering with Linux, home servers, or just curious about networking. #Linux #Ubuntu #Networking #HomeServer #SSH #DevOps #Netplan #LearningByDoing

These cover most of what you’ll actually use: 🔹 top / htop: real-time resources 🔹 df -h: disk space check 🔹 du -sh: find space hogs 🔹 ps aux | grep: track processes 🔹 tail -f /var/log/... live logs 🔹 systemctl: manage services 🔹 ssh: access servers 🔹 scp / rsync: move files safely Master these, and production stays under control. #linux #devops #sysadmin #production #techinsights

🚨 Disk space – the silent culprit behind VM & service failures! Recently, I ran into an issue where a VM refused to restart services, throwing the error: 👉 “No space left on device” At first, running du -sh * showed normal usage… but the real problem was elsewhere. Here’s what helped me troubleshoot ⬇️ 🔎 Essential Disk Checks in Linux: 💽 Check overall disk usage: df -h 📊 Check inode usage (often overlooked): df -i 📂 Find the biggest directories: sudo du -sh /* | sort -h 🗑️ Detect deleted files still eating space: lsof | grep deleted ⚡ Takeaway: Disk space is not just about “storage”. It directly impacts: ✔️ Service restarts ✔️ VM stability ✔️ Uptime & reliability ✅ Lesson: Always include disk utilization checks (both space & inodes) in your troubleshooting checklist. 💬 What’s your go-to Linux command for catching disk issues quickly? #Linux #DevOps #CloudEngineering #Troubleshooting #SRE

Recently, while working on Proxmox VE customer projects, I often used ethtool to check the mapping between network interface cards and their physical ports. I got tired of repeatedly running commands, so I decided to write a small tool that updates in real time—much more convenient. This tool is suitable for network interface monitoring in Proxmox VE or Linux environments. It provides real-time views of physical NICs and bridge/bond interface statuses, making it easy to check interface-to-physical-port mappings and cable connections—especially handy during system installation.
