Overall poorly scaffolded learning with little practical value.

The lectures were the best part, though the instructor brought up very complex topics without diving into them. There were some good resources and links to documentation, but just reading docs would have been more valuable than the class, which doesn't cover anything in much depth.

The assessments were terribly written, consisting of several multiple choice questions that often tested irrelevant trivia rather than important concepts (e.g. "what is the name of XYZ distribution's tool for ABC?", rather than "what is a secure procedure for doing ABC?"). The final project was poorly specified: beyond the usual "make reasonable assumptions to fill in the gaps", it didn't even specify what certain types of end users were trying to do in the system it asks you to design. The peer grading instructions did not provide a good rubric or example answers for orienting one's judgement and expectations of other students answers. All in all, as a former teacher, it feels as if the assessments were likely banged out by an inexperienced TA in an afternoon.

Lastly, for this type of course, it's inexcusable that prebuilt virtualized environments and practical problems weren't provided or used in excercises. I came to this course as a developer looking to broaden my ops side experience; I know that the way everyone in industry actually learns things is by experimentation, trial and error. A strong course would have practical labs to create and then pen test the security features discussed; it might ask students to spin up broken images, investigate problems, and fix them to a specification. I've frequently done similar training at tech conferences; it's not hard to design this. Unfortunately, the course design smacks of laziness and unwillingness to put together the materials necessary to actually have students learn and retain the topics.

I don't think I learned much from this course.

The course was boring a little.

The instructor didn't prepare what he needs to talk in the lecture and he was thinking on the fly which I think is not good for teaching.

The course was not practical in my opinion.

There's no practice and there is not enough info for a subject review neither. It's no for beginners(there are some complicated mechanisms introduced) and it's not for experienced(there are simple things introduced)

Most of these Linux commands are depreciated/obsolete and the course is a bit wrong and the questions need to be updated. I work on Linux everyday and this isn't correct information. I would first read a book then try this course and you'll notice the errors

Complete garbage! Too complicated for those not comfortable with GNU Linux and too basic for those who are!!

Got introduced to a lot of new systems used in this domain. Definitely recommend anyone interested to check out. Well explained content. Thanks for sharing!

The course was excellent and the instructor was amazing. The course material was well prepared and very clear. I strongly recommend this course!

Excellent instructor who has a lot of practical knowledge of network security. I would certainly enroll in another course if it were offered through the same instructor.

Truly enlightening course. Can be taken by novices who want to get started with Enterprise Linux and also by professionals looking to up their skills. Highly recommended.

its very interesting courses i have learned . i also suggest to learn this course.

very thankful to coursera team.

The best one I ever had. It included theoretical concepts along with practical knowledge. The trip to the servers was awesome. I have been learning datacenters but after watching this I finally grasped what a data center is. Loved the material

I enjoy the lectures. The professor has a good speaking and teaching style which keeps me interested. Lots of concrete math examples which make it easier to understand. Very good slides which are well formulated and easy to understand

Very good course for the basic user. Even for a user that has a few months of experience with Linux servers, there are some things to learn.

Overall good course with lots of knowledge about the linux server management and security, it's help me clear the basic concepts.

simply i would like to thank the university of Colorado the supervisor of this course and Coursera for the quality of this course

It was very productive and informative course and the way of learning online was very comfortable

Very useful course. The lecturer is a high-level Linux professional. Respect.

A well defined course, beginner friendly, wish had some more content as I felt it got over pretty quick.

It's was a balance between theory and practicals but wasn't up to the expectations. New members may not be able to understand some advanced concepts directly used without prior explanation. Overall, a decent course to start off from, to know the basics of enterprise-level Linux server management.

much harder to follow or keep interested when teacher isn't on screen

Too many "readings" which are simply links to other resources on the web, or which are the PowerPoint slides that he may or may not have used in his video lectures. These readings should really be made into lecture videos. The lectures themselves are wordy and don't really explain what's behind all the lingo he uses.

not Well organized material

I loved the fact that the course presentations are also downloadable for review. The readings are also on point and not too long for supplementary reading. Finally, I like the peer graded assignment. It made me think creatively and the support to upload an optional diagram was great

This course is ideal for junior system administrators who know Linux basics but new to manage Linux server. Some new commands and topics need to be referred further. The instructor has industry hands on skill on the domain. It helped me a lot.Thank you so much.

Excellent course and the topics are very useful, maybe to be more interactive to put a console into the platform but installing a VM is joyful. A suggestion: The command chkconfig is no longer available in Ubuntu. Please update that !
