RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:

After reading Chapter 2. Securing Your Network I have following two proposals:

1. Several topics mention files in /lib directory. Somewhere in the beginning of the book (1. Document Conventions???) there should be a statement saying that on 64-bit systems some files mentioned in the text may be located in /lib64 instead on /lib.

2. 2.1.4.3.1. The su Command
"5. Open the PAM configuration file for su (/etc/pam.d/su)..."
should not be included in the ordered list because it is confusing. According to the precedent text items in the list describe steps for the GUI alternative to
"usermod -G wheel <username>". Therefore the /etc/pam.d/su step (5th) should be excluded from the list since it is not related to the User Manager. Instead, "/etc/pam.d/su" part should be mentioned separately outside (after) the list.
