What file contains the list of port numbers (and associated names) monitored by inetd? A. /etc/services B. /etc/nsorder C. /etc/nsswitch.conf/ D. /etc/hosts E. None of the above

The correct answer is A. /etc/services.

/etc/services is a text file that contains a list of port numbers and their associated services. The file is used by the inetd daemon to determine which service to start when a connection is made to a particular port.

The file is formatted as follows:

port/protocol service name

For example, the following line in the file indicates that port 80 is used by the HTTP service:

80/tcp http

The file is typically owned by root and has a mode of 644.

The following are the other options:

• B. /etc/nsorder: This file contains the order in which name servers are used to resolve hostnames.
• C. /etc/nsswitch.conf/: This file contains the configuration for the name service switch.
• D. /etc/hosts: This file contains a list of hostnames and their associated IP addresses.
• E. None of the above: This option is incorrect.
