Red Hat Linux 7.2 Documentation Errata

If you find any errors in the Red Hat Linux documentation, or just have a suggestion, please read the Submitting Documentation Errata page.

x86 Installation Guide

None available

Getting Started Guide

Documentation Resources

The command cd su should be su.


Installing RPMs From the Installation CDs

The sentence "Package descriptions are available online at http://docs.redhat.com" is incorrect. Package descriptions are not available online. Also, the URL for the Red Hat Documentation site is http://www.redhat.com/docs/.

The command cd su should be su.

Customization Guide

Kickstart Options

The langsupport option should be marked required.


Kickstart Options

The part --onprimary option is no longer a valid kickstart option due to a limitation of GNU parted. GNU parted is the partitioning subsystem used by Disk Druid in the installation program.


chkconfig

The warning is incorrect. Services managed by xinetd are immediately affected by chkconfig. For example, if xinetd is running, finger is disabled, and the command chkconfig finger on is executed, finger is immediately enabled without having to restart xinetd manually.

Reference Guide

Firewalling with iptables

The following statement is incorrect:

If you require instructions for constructing iptables rules or setting up a firewall based on these rules, please see the Official Red Hat Linux Customization Guide.

The Official Red Hat Linux Customization Guide does not contain this information. It only discusses using GNOME Lokkit as a method for configuring a basic firewall solution. If you need further information on iptables, refer to the Red Hat Support page on Creating a Firewall.


BIND Configuration Files

The following warning statement is incorrect:

Do manually edit the /etc/named.conf file or any files in the /var/named directory if you are using the BIND Configuration Tool.

This passage, unfortunately, is missing the critical word not. If you do manually edit these files while using bindconf, any changes you make to the files will be overwritten the next time you use bindconf to configure your DNS server.


Configuring Sendmail to Accept Outside Connections

The following excerpt was accidentally left out of the The Official Red Hat Linux Reference Guide:

By default, sendmail does not accept network connections from any host other than the local computer. If you want to configure sendmail as a server for other clients, please edit /etc/mail/sendmail.mc and change DAEMON_OPTIONS to also listen on network devices, or comment out this option all together. You will need to regenerate /etc/sendmail.cf by running:


m4 /etc/mail/sendmail.mc > /etc/sendmail.cf
            

(NOTE: You must have the sendmail-cf package installed for this to work.)


Stopping Spam with Sendmail

The following passage in the The Official Red Hat Linux Reference Guide is incorrect:

Because /etc/mail/access is a database, you need to use makemap to activate your changes by recreating the database map. This is easily done by running the makemap hash /etc/mail/access < /etc/mail/access command as root.

The name of the database is actually /etc/mail/access.db, not /etc/mail/access. The rest of the instructions are correct.


NFS Server Configuration Files

Under the /etc/exports section, an incorrect statement was made about wildcards and IP addresses in the NFS server configuration file. It should read:

wildcards — Where a * or ? character is used to take into account a grouping of fully qualified domain names that match a particular string of letters. Wildcards are not to be used with IP addresses; however, they may accidentally work if reverse DNS lookups fail.
