SYS255: Week 3 - Linux

CentOS setup guides:

CentOS Setup: Hostname and Static IP

CentOS Setup: Create a user and set password

Working Notes

I'd been running a standard Ubuntu installation on my laptop for a solid few years, but switched to Kubuntu after my hard drive was wiped during some repairs last spring. Because of this, I was not expecting to see anything new for an intro to Linux lab. I was overconfident, and I learned about the history command, and I learned how to set up a static IP and change the hostname through the command line (at least on CentOS). Additionally, while it was not directly a part of the lab, I messed up the directory name for this week's screenshots, and messed around with the git command and ssh-keygen when trying to fix the url. Because Github.com doesn't seem to let you edit the names of images, as far as I can tell, I'd have to delete the image file and upload a replacement one to move it from the directory cncs_journal/wiki_images/sys255/lab3/ to cncs_journal/wiki_images/sys255/lab_3/, to maintain a consistent directory naming system. While I was able to figure out how to clone via ssh, I was not familiar enough with the git command to figure it out in a timely manner. Realizing how much there is for me to still learn, it took me about five seconds of searching on DuckDuckGo to find a How-To Geek article titled 37 Important Linux Commands You Should Know, and I realized how overconfident I really was, having not heard of around a quarter of the listed commands. Certainly better than the average computer user, but probably less than someone who uses Linux as their primary desktop OS and wants to go into Cybersecurity ought to know.

Major Takeaway: don't overestimate my own knowledge of technologies.
