Setting up Ubuntu Server at Home with SSH

Happy to share the video on deploying an Ubuntu Server in VirtualBox. What would it help you with? Well, everything you can do on an Ubuntu Server. Furthermore, such a deployment doesn't incur any costs and you get to keep your host (nothing changes there). One of the best use cases for students with such a setup is they can taste different operating Systems and if they want to move to a new OS, test it out first in the VirtualBox. I recently used it to deploy an RC and tested ZTA. And there are a plethora of use cases with such a setup. If you find the video helpful, please feel free to like share and comment: https://lnkd.in/gBAxnP6e #cisco #thenetworkviking #ubuntu #labs #labsetup #serveradministration #linux #resource #zta #secureaccess

Essential Linux Troubleshooting Commands Every SysAdmin Should Know 🐧 Working with Linux servers (CentOS, Ubuntu, etc.) means relying heavily on the terminal. As IT Support Specialists and System Engineers, quick troubleshooting with the right commands can save hours of downtime. Here are some go-to commands for everyday troubleshooting: 🔹 1. System Health top / htop → Monitor CPU, memory & processes uptime → Check load averages 🔹 2. Disk & File System df -h → Check disk usage du -sh * → Find large directories/files 🔹 3. Network ping <host> → Check connectivity netstat -tulnp → View active ports ss -tulwn → Modern alternative to netstat 🔹 4. Logs & Errors tail -f /var/log/syslog (Ubuntu) / /var/log/messages (CentOS) → Real-time logs journalctl -xe → Detailed error logs 🔹 5. Services systemctl status <service> → Check service status systemctl restart <service> → Restart services 🔹 6. Package Management Ubuntu/Debian → apt update && apt upgrade CentOS/RHEL → yum update These are the fundamental tools I use almost daily for keeping Linux systems running smoothly. 💡 What’s your must-use Linux troubleshooting command?

Today, let’s tackle another common confusion: 🔹 shutdown -h now vs shutdown -r now 1️⃣ shutdown -h now The -h flag stands for halt. Immediately powers off the system. Think: h → halt. 2️⃣ shutdown -r now The -r flag stands for reboot. Restarts the system right away. Think: r → restart. ⚡ Pro Tip: Always make sure you’ve saved your work and notified users before running these—especially on shared servers. Small differences, big impact. One halts, the other reboots. #Linux #DevOps #SysAdmin #LinuxTips #CloudComputing
