  D. The exports entry on the server machine does not include the option no_root_squash.
  D. The exports entry on the server machine does not include the option no_root_squash.

• Question 473:

  A. uname
  B. limit -a
  C. usrlmt
  D. ulimit
  D. ulimit

• Question 474:

  workgroup = group1

  guest account = nobody

  What else is needed for this to work?

  A. nobody must be a valid group on the server.
  B. nobody must be a user name listed in /etc/passwd.
  C. group1 must be a valid group on the server.
  D. workgroup must be a valid group on the server.
  B. nobody must be a user name listed in /etc/passwd.

• Question 475:

  In the /etc/nsswitch.conf file, which directive specifies what "databases" are queried and in what order for host name lookups?

  hosts

• Question 476:

  How can you enable onscreen (non-printing) numbers in a vi session?

  A. :set num
  B. :se nu
  C. :set -o number
  D. :set +o num

• Question 477:

  The system's timezone may be set by linking /etc/localtime to an appropriate file in which directory? (Provide the full path to the directory, without any country information)

  /usr/share/zoneinfo/

• Question 478:

  What runlevels should never be declared as the default runlevel in /etc/inittab?

  A. 1
  B. 3
  C. 5
  D. 6
  A. 1
  D. 6

  ---

  Standard Runlevel are:

  0 - halt (Do NOT set initdefault to this) 1 - Single user mode 2 - Multiuser, without NFS (The same as 3, if you do not have networking) 3 - Full multiuser mode 4 - unused

  5 - X11

  6 - reboot (Do NOT set initdefault to this) 1 means single user mode and 6 means reboot. Which are not recommended for default runlevel.

• Question 479:

  You have just recompiled a new kernel and rebooted your system with the new kernel. Unfortunately you are getting "Can't locate module" error messages. Which of the following is most likely to be the source of the problem?

  A. You copied the modules to the wrong directory.
  B. You did not configure modular support into the kernel.
  C. You did not run depmod after installing the modules.
  D. You dud not install the modules.
  B. You did not configure modular support into the kernel.

  There is one more step needed for the build process, however. You have created the kernel, but now you need to create all the loadable modules if you have them configured. Be aware that typical distribution kernels tend to have almost every feature installed, plus a few others for good measure. These can typically take an hour or so to build on our Athlon XP1800. The stock kernels are somewhat leaner by default and take, on average, 25 minutes to compile. To build the modules we run: $ make modules If you forget to enter make modules command, you will get that message. Follow these steps while recompile the kernel.

• Question 480:

  Type in the simplest command, including any switchs, to rebuild the modules.dep file after you have made changes to the modules.conf file.

  depmod -a

  depmod creates a list of module dependencies, by reading each module under /lib/modules/version and determining what symbols it exports, and what symbols

  it needs. By default this list is written to modules.dep in the same directory.

  The normal use of depmod is to include the line /sbin/depmod -a in one of the files in /etc/rc.d so the correct module dependencies will be available after booting the system. depmod -e prints a list of all unresolved symbols.
