Does anyone knows where can I find the first webinar of Sander’s Working with systemd (RHCSA and RHCE) that was on Feb. 13th at 9 AM PST / 6 PM CET ?
Thanks
All Sander’s webinars are removed after one week. Your only chance would rely on somebody having recorded the one that interests you and making it freely available. I’m personally not aware of such a thing. Sorry.
thanks a lot for your website, I would like to suggest these free resources:
http://www.tecmint.com/category/rhcsa/
http://www.tecmint.com/category/rhce/
and the respective ebook “Introducing the RHCSA and RHCE Exam Preparation Guide” for $25
🙂
Thanks. I aware of the Tecmint RHCSA & RHCE resources and I will try to display them somewhere.
However, concerning the ebook, because it is not free, I don’t plan to speak about it.
Thanks for all these resources. You can also check Linux interview questions
Thanks.
I will. Thanks.
