There's much to learn in OPS345, and it's the third course in order to be able to learn the new stuff - students must OPS stream, so we're assuming you learned some basics in ULI101/OPS245. As a minimum, you should be comfortable usingwith:* Using a Linux desktop as a workstation,* Using the terminal for various tasks, including:** using Using an ssh client** editing Editing text files (ideally with vi)** file File and permission management** managing Managing users** managing Managing storage devicesincluding LVM, and filesystems, mounting* basic * Managing services using systemctl** Reading and monitoring log files** Using and writing simple shell scripts* Basic networking concepts, including:** public Public IPs and private subnets* systemctl start/stop/status/enable/disable* using and writing simple shell scripts* Simple iptables to check the firewall setupconfigurations* Reading, writing, and oral communication . This last one is so important that many people can BS their way past the fact that they have no technical skills to explain what they learnedat all.
