Errata

Issue	Author's Response
Chapter 11 page 520 says that max number of connection means is amount of connection that a browser can have with one server that is not sensible according to apache documents.I think other description in this page should be revised.	The page says the Max Number of Connections is the number of concurrent connections the web server will service, in line with the Apache documentation. The browser qualifier explains that browsers can make multiple simultaneous connections, so the Max Number of Connections does not equal the number of browsers whose requests can be fulfilled simultaneously. That number can be lower, depending on the time it takes to handle a request and the number of connections a browser makes.
Page 540, 3rd paragraph reads "data needs to be written from disk" should be "data needs to be read from disk".	This is correct, that would be a typo.
Page 88 listing 3-11 #chmod u+x myfile #chmod u-x,og+w myfile #chmod 654 myfile After our update: -rwxr--r- should be: -rw-r-xr--	The correction is accurate.
Chapter 2 page 22 bottom of page referring to Figure 2-10 and states "only disk available to us, /dev/sda Also NOTE: refers to disk /dev/sda in Firgure 2-10 but Figure 2-10 only has an LVM reference.	This errata is correct, both the note on page 22 and the line directly above it should refer to the LVM volume in Figure 2-10, not /dev/sda.
Introduction page xxi in the hightlighted NOTE: "Red Hat Enterprise Linux or Microsoft Windows Server 2007 are examples of operating systems." No such thing as Microsoft Windows Server 2007. There is Microsoft Windows Server 2003 and 2008 however.	That is quite correct - please excuse the typo.
In chapter 17, page 865 in the box CGU should be GNU	Correct.
On page 934 should not the line next_server 192.168.0.0.1 read next_server 192.168.0.1	This is correct. That is a typo.
Chapter 19 in the Installing Puppet section under the sub-heading Red Hat Installation. The Puppet master package from EPEL is listed a puppet-master but in fact is puppet-server. The package listed in the yum install command is correct but citely incorectly in the surrounding text.	This errata is correct.
