Describe your experience with Linux-based systems usage and administration.

In my experience with Linux, I have been involved in installing and configuring server distributions (for example, Ubuntu Server, CentOS). Administration included managing users and access rights, configuring network interfaces, installing and updating packages via managers (apt, yum). I also configured services such as SSH for remote access, Apache/Nginx for web servers, and databases (MySQL, PostgreSQL).

For monitoring, I used standard utilities (top, htop, netstat, journalctl) and set up automated tasks via cron. An important part was ensuring security — configuring firewalls (iptables, ufw), regularly updating the system, and backing up data.

Example command for updating the system and installing a package:

sudo apt update && sudo apt upgrade -y
sudo apt install nginx

I also worked with system logs and logs for troubleshooting, and when necessary, I configured scripts for automating routine tasks.
