So much like week 1, the day started with intros and just general talk about Linux experiences. Most of the people from this class were also in the week 1 class I attended 2 weeks ago. A lot of the other students seem to be having a hard time grasping concepts.
Day 1
So far, I have learned more than I did in week 1. A lot of command line tasks to complete. Most of the Linux experience I have is all through using ssh and the CLI. So this really isnt that difficult for me so far. We covered 4 chapters on day 1. I will break them down here.
Chapter 1 - Automated Installation of Red Hat Enterprise Linux
- Create a kickstart file with system-config-kickstart
- Make the kickstart file available to installers
- Create boot media
- Point installer to a kick start file
- Modify a kickstart file
Chapter 2 - Accessing the command line
- Accessing the command line locally
- Accessing the command line using ssh
Chapter 3 - Intermediate command line tools
- Using hard links
- Archives and compression
- Intro to vim
- Basic vim workflow
Chapter 4 - Regular expressions, pipelines, and I/O redirection
- Basic regular expressions
- Using grep
- Pipelines and redirection
I had a little bit of a hard time with the IO redirection as there are SO many options. I hope there isnt much of that on the test, as it seems to be a weak point for me. More to come later.
Day 2
Day 2 went in depth in a few things. I feel like I learned some more as well as really solidified the concepts and objectives that are to be covered on the exam.
Chapter 5 - Network Configuration and troubleshooting
- Network configuration files
- Basic troubleshooting process
- Network troubleshooting tool kit
Chapter 6 - Managing simple partitions and file systems
- Adding file system space
- Encrypting partitions
- Adding swap space
Chapter 7 - Managing flexible storage with logical volume manager
- Review LVM concepts
- Implement LVM storage
- Grow a file system
- Add a disk
- Snapshot as backup
We only covered the 3 chapters on day 2, but it feels like so much was thrown at us. I feel that I am able to remember the tasks given to us, and feel that I will be able to conquor the EX200 exam on Friday.
Day 3
Chapter 8 - Accessing Network File Sharing Services.
- Mounting network shares
- Automount network shares
- NFS
- CIFS
- Using /net
- autofs
Chapter 9 - Managing User Accounts
- User definition
- Manage local users
- Password expiration
- Password policies
- /ect/passwd file
This seemed to be a pretty easy and straight forward chapter. Creating and managing users is a pretty simple concept, and I would imagine that anyone with any linux experience has done it.
Chapter 10 - Network Users Accounts with LDAP
- LDAP Client configuration
- Automounter metacharacters
- getent command
- Network mounting home directories
- autofs
Chapter 11 - Controlling access to files
- Managing groups
- Access control lists
- getfacl command
- setfacl command
- default acl's
- collaborative directory permissions
Chapter 12 - Managing SELinux
- Review basic SELinux concepts
- Displaying and setting SELinux modes
- Displaying and setting SELinux file contexts
- Tuning policy behavior with SELinux booleans
- Monitoring SELinux policy variations
The instructor quickly went over this chapter and flat out told us that this wasnt going to be on the exam. This was also the last topic of the day.
