It is possible that your system may be missing a few of them if the corresponding program that would
need that file is not installed.
Next, we will take a look at each one.
3.7.1.1. /etc/sysconfig/amd
The /etc/sysconfig/amd file contains various parameters used by amd allowing for the automount-
ing and automatic unmounting of file systems.
3.7.1.2. /etc/sysconfig/apmd
The /etc/sysconfig/apmd file is used by apmd as a configuration for what things to
start/stop/change on suspend or resume. It is set up to turn on or off apmd during startup, depending
on whether your hardware supports Advanced Power Management (APM) or if you choose not to use
it. apm is a monitoring daemon that works with power management code within the Linux kernel. It
can alert you to a low battery if you are using Red Hat Linux on a laptop, among other things.
3.7.1.3. /etc/sysconfig/arpwatch
The /etc/sysconfig/arpwatch file is used to pass arguments to the arpwatch daemon at boot
time. The arpwatch daemon maintains a table of Ethernet MAC addresses and their IP address pair-
ings. For more information about what parameters you can use in this file, type man arpwatch. By
default, this file sets the owner of the arpwatch process to the user pcap.
3.7.1.4. /etc/sysconfig/authconfig
The /etc/sysconfig/authconfig file sets the kind of authorization to be used on the host. It
contains one or more of the following lines:
• USEMD5=
value , where value is one of the following:
• yes — MD5 is used for authentication.
• no — MD5 is not used for authentication.
• USEKERBEROS= value , where value is one of the following:
• yes — Kerberos is used for authentication.
• no — Kerberos is not used for authentication.
• USELDAPAUTH= value , where value is one of the following:
• yes — LDAP is used for authentication.
