Introduction to Linux Lab - Zacham17/my-tech-journal GitHub Wiki

Brief Summary

In this lab, I configured a linux VM and added it to the domain. I also used SSH to remotely connect to the linux VM from the workstation VM.

Notes

  • I created a user on the new linux VM with the useradd command.
  • I added the new user to the "wheel" group, which is a local admin group in CentOS Linux.
  • I made sure I was able to connect to other machines on the domain by using the ping command.
  • I utilized Windows Powershell to SSH into the linux VM from the windows workstation VM.

Commands Used In this Lab:

  • useradd : Is used to create a user on the machine.
  • ssh : Is used to establish a remote connection to another host.
  • history : Shows commands previously entered.

Deliverable #6 Commands:

  • df : reports file system disk space usage. It shows the amount of disk space available on the file system. The -h option prints the size output in a human readable format.
  • free : displays the amount of free and used memory in the system. You can use options such as -b, -k, -m, and -g to change what unit to display the output in.
  • w : shows who is logged on and what they are doing. The syntax is w [options] user [...]. Login name, tty name, remote host, login time, idle time, JCPU, PCPU, and the command line of the user's current process are shown by this command.

New Terms/Steps

  • Something in this lab that I wasn’t familiar with was bash history and how to access it.
  • I also wasn’t familiar with the /etc/skel directory and using it when creating users.
  • Other than those topics, I was fairly familiar with the other steps in this lab.
