Thank you mike, I will try to call them.

I am going to give my thumbs-up for this book! I bought the previous edition which was based on RHEL5, and it helped me IMMENSELY when I was studying for my RHCSA.

FYI, I've submitted my first set of errata to the publisher. But I fully expect it to be a continuous process, and stand ready to hear more. One reader has pointed out that on p423, Ch 7, Figure 7-3 is a duplicate of Figure 7-4. The correct version of Figure 7-3 is attached to this message.

Please report RHCSA/RHCE book errata soon
 

FYI, if you've found errors other than what's already been reported on my book, I'd appreciate hearing about it in the next couple of days or so.

I've submitted my first batch of errata, and hope it'll be available a couple of weeks after I give the go-ahead.

Any update on errata?

I'm scheduled to take RHCSA course at the end of September. I've found your book very helpful!! I've only been a Linux/Vmware systems engineer for 4 months but have been going to college for 2 1/2 years completing an AAS in Linux networking. I also received my L+ and LPIC-1 certs. I'm excited and nervous about the course!

Thanks for all of your hard work on the book!

I promise to post here when errata is available on the mheducation.com website. I'm hopeful that it'll be there in the next few days. It should be listed at http://www.mhprofessional.com/getpag...ta.php&cat=112 .

Thanks for your kind words on my book. If/when you're comfortable doing so, I'd appreciate a five-star review on Amazon with your thoughts.

Is Red Hat the best form of linux to get certified in as far as for work goes? I am new here, I am trying to figure out what certificates would be best to get first. I figure microsoft and linux are the biggest. Microsoft server 2008 and 2011, and I know linux runs on my work computers. I've seen my computer be booted up in linux, emptied out and then windows was re-installed remotely. I hear Linux is a popular choice for most businesses. Is Red Hat the main form I should study for my caree?

Dear netto12,

While I think the Red Hat certs are best, the answer to your question is "it depends". For example, what version of Linux do you use at work?

One reason why I think Red Hat certs are an excellent choice is the way the exams are given. They are based on all "practical" questions. The questions are based on the objectives listed for exams such as the RHCSA (ref http://www.redhat.com/certification/rhcsa/objectives/ ) and the RHCE (ref http://www.redhat.com/certification/rhce/objectives/ ). During the exam, you sit down at an actual Red Hat system and are asked to configure it to a list of requirements. The score you get depends solely on the way you configure your Red Hat system in the time given.

Based on the practical nature of the Red Hat exams, they are perhaps the most respected exams in the Linux arena. (However, the people behind the LPI exams strongly dispute that claim, and that can be a long discussion. SUSE has their own certifications too.)

If you're new to Linux, the Red Hat certs might be a bit too difficult. Many newer Linux users take the LPI level 1 certs first.

Book Errata
 

FYI, errata for the 6th edition is now available from http://www.mhprofessional.com/produc...sbn=0071765654

Click on the errata link in the left side of the page.

Thanks everyone for your patience!

Awesome, Thanks Mike!

Hello Michael,
I downloaded the errata from the link you gave, but the file "0071765654_Errata_10-14-11.txt" within the archive refers to another file "0071765654_Errata_8-25-11.txt" apparently with more errata. Where can I find this earlier errata file?
Thanks

Dear gonk23,

I gather there was an error in processing new errata from Oct 14, accidentally overwriting the original errata. Original errata from 8-25 attached. (I will delete it from this message as soon as it reappears in some form on the MHprofessional.com site.)

11/8 update

(Since the updated errata is now on the MHprofessional.com site, I deleted the errata from the attachment here.)

Thanks!

setting up test environment
 

I have a physical box with one ethernet nic @ 192.168.1.104. This machine has access to internet through home router/gateway at 192.168.1.1

I have server1 vm with 192.168.122.10 with 192.168.122.1 as GW. VM nic is set to NAT to eth0.

So 2 different networks. I have ip forwarding enabled and i see the rule in ip tables.
I cant get access to internet on VM. What am I doing wrong?

Dear yelena1,

I don't have enough info from your note.

Have you tried the ping commands in Chapter 3, from the localhost through your public IP address?

Have you made sure the DNS server in /etc/resolv.conf is good and is also accessible?
