I have over five years of experience in Linux system administration, managing both physical and virtual servers. I frequently use tools like SSH for remote access, Bash for scripting, and Ansible for configuration management. I also have experience with monitoring tools such as Nagios and Prometheus to ensure system uptime and performance.

I prioritize security updates by regularly checking for vulnerabilities and applying patches as soon as they are available. I use package managers like APT or YUM to automate the update process and ensure all systems are up-to-date. Additionally, I maintain a patch management log to track applied updates and their effectiveness.

I have extensive experience with Docker, having used it to containerize applications and manage multi-container environments. I also have hands-on experience with Kubernetes for orchestrating these containers, including setting up clusters, managing deployments, and scaling applications. My experience includes integrating Kubernetes with CI/CD pipelines for automated deployment.

I start by using basic network diagnostic tools like ping, traceroute, and netstat to identify the source of the issue. If the problem persists, I delve deeper into the network configuration files and logs. I also use Wireshark for packet analysis to pinpoint any anomalies. My approach is systematic, ensuring I cover all potential causes before concluding.

I implement a comprehensive backup strategy using tools like rsync, tar, and cron jobs to automate regular backups. I ensure data redundancy by storing backups on separate physical or cloud storage. For disaster recovery, I maintain detailed documentation and test recovery procedures periodically to ensure they are effective and up-to-date.
