Question No: 231 – (Topic 2)

The host aubie has the following entry in its /etc/nsswitch.conf file (unrelated lines are omitted):

hosts: nis [NOTFOUND=return] files

And the following in its /etc/inet/hosts file:

#

# Internet host table

#

127.0.0.1 localhost

10.7.8.101 aubie loghost

Given the output of the following command:

# getent hosts aubie

10.7.8.101 aubie

Why is the loghost alias NOT displayed?

  1. The getaliasbyname NIS map is missing.

  2. The Name Service Cache Daemon (nscd) is not running.

  3. The /etc/inet/hosts file contains spaces instead of tabs.

  4. The loghost variable is not defined in the /etc/syslog.conf file.

  5. The NIS map entry for aubie does NOT contain the loghost alias.

Answer: E

/etc/nscd.conf file contains the lines:

#

#

#ident quot;@(#)nscd.conf 1.6 01/01/26 SMIquot;

#

debug-level 0

positive-time-to-live passwd 600

negative-time-to-live passwd 5

suggested-size passwd 211

keep-hot-count passwd 20 old-data-ok passwd no check-files passwd yes

positive-time-to-live hosts 3600

negative-time-to-live hosts 5

suggested-size hosts 211

keep-hot-count hosts 20 old-data-ok hosts no check-files hosts yes
