Finger, telnet and FTP can be configured via which of the following Linux
configuration files?

A.
inetd.conf

B.
httpd.conf

C.
srv.conf

D.
linux.conf

E.
None of the above.

Explanation:
Inetd should be run at boot time by /etc/rc.local (see rc(8)). It then listens for connections
on certain internet sockets. When a connection is found on one of its sockets, it decides
what service the socket corresponds to, and invokes a program to service the request.
After the program is finished, it continues to listen on the socket (except in some cases
which will be described below). Essentially, inetd allows running one daemon to invoke
several others, reducing load on the system.Inetd.conf is its configuration file.
